Six Things That Citizens Around the World Urgently Need to Know About Climate Change In Light of Several Recent Scientific Reports

This article identifies and explains six things that most citizens around the world, although particularly those in developed countries, need to understand about climate change in light of the most recent climate change science. These six things are:

  1. The enormous magnitude of GHG emissions reductions needed to prevent catastrophic warming.
  2. The speed of GHG emissions reductions needed to prevent catastrophic warming.
  3. No nation may either legally or morally use national self-interest alone as justification for their failure to fully meet their obligation under the UNFCCC.
  4. No nation may either legally or morally use scientific uncertainty as justification for their failure to fully meet their obligations under the UNFCCC.
  5. Developed countries must legally, morally, and practically more aggressively reduce their GHG emissions than developing countries
  6. Developed countries must legally, morally, and practically help finance mitigation and adaptation programs in poor developing countries.

The need for broad understanding among civil society of these issues follows from several recent scientific reports on climate change. For instance, on October 8, 2018, the Intergovernmental Panel on Climate Change (IPCC) issued a Special Report on limiting global warming to 1.5 degrees C above pre-industrial temperatures.  This landmark report, along with several additional recent scientific studies published in the last few months including a paper published by the Proceedings of the US National Academy of Sciences on July 21, 2018, Trajectories of  the Earth System in the Anthropocene by Steffen et.al., and a paper published in mid-August of this year in Nature Communications by Anthony et. al., 21st-Century Modeled Permafrost Carbon Emissions Accelerated by Abrupt Thaw Beneath, lead to the conclusion that the international community is facing an urgent existential crisis that threatens life on Earth. Preventing this catastrophe requires the entire international community at all levels of government (national, state, regional, and local) to engage immediately in an unprecedented effort to rapidly reduce GHG emissions to net zero in the next few decades.

Although the October IPCC report on 1.5 degrees C warming received some significant notice in the US media, the recent US elections on November 6th in which climate change played only a very minor role at best, demonstrates a startling lack of understanding about the enormity and urgency of the climate threat facing the international community. Because of the immense ramp-up of programs and efforts needed to reduce the staggering threat of climate change depends on broad understanding of the scale of the problem facing the human race, and given the apparent ignorance of most citizens about the magnitude and urgency of the climate change crisis and other issues discussed in this paper, concerned citizens need to mount an aggressive educational program to inform civil society about aspects of the climate change threat that appear to be poorly understood. These issues include the following:

1. The Immense Magnitude of GHG Reductions Urgently Needed to Prevent Catastrophic Warming

The IPCC Special Report concludes that limiting global warming to 1.5°C would require rapid, far-reaching, and unprecedented changes in all aspects of society.  This is so because to limit warming to 1.5 C, CO2 emissions would need to fall by about 45 percent from 2010 levels by 2030, reaching ‘net zero’ around 2050 according to the IPCC Special Report. This means if global CO2 emissions have not fallen to net zero levels by 2050, any remaining emissions would need to balanced by removing CO2 from the air.

The Steffen et. al. paper also describes how the positive feedbacks depicted in the following graphic, once triggered could initiate other feedbacks creating a cascade of positive feedbacks, each of which could speed up the warming which is already causing great harm and suffering around the world. The paper claims this mechanism could make life on much of the Earth uninhabitable which could lead to social collapse on the global scale and ultimately to warming increases that human reductions of greenhouse gases (GHG) emissions alone would not prevent additional warming until the global system reached a new temperature equilibrium at much higher temperatures than the human race has ever experienced. In other words, cascading positive feedbacks in the climate system could result in humans losing control over reducing disastrous warming.

The Steffen et.al paper also explains how human-induced warming of slightly over 1.0 degrees C is already rapidly approaching levels that may trigger positive climate feedbacks which could greatly accelerate the warming already plaguing the world by causing record floods, deadly heat waves, droughts, increasing tropical diseases, forest fires, more intense and damaging storms, sea level rise, coral bleaching, acidification of oceans, all of which are contributing to increasing the number of refugees which are destabilizing governments around the world.

The Anthony et.al paper also explains that, contrary to common assumptions previously made by many in the international community that positive feedbacks in the climate system that could cause abrupt temperature increases would not likely be triggered if warming could be limited to below 2C above pre-industrial levels, positive feedbacks could be initiated between current temperatures which have risen slightly above 1.1C and 2C. Moreover, the additional warming caused by these feedbacks could initiate other feedbacks creating a cascade of positive feedbacks, each of which could speed up the warming which is already causing great harm and suffering around the world, phenomena which threaten life on earth.

For these reasons, citizens around the world need to understand the urgent need to reduce GHG emissions to net zero as soon as possible.

2The Speed of GHG Reductions Needed to Prevent Catastrophic Warming.

Every day that nations fail to reduce their GHG emissions to levels required of them to achieve a warming limit goal such as 2 degrees C makes the problem worse because the carbon budgets for the whole world that must constrain global emissions to achieve any warming limit goal shrink as emissions continue. Therefore, the speed that nations reduce their GHG emissions reductions is as important as the magnitude of the reductions identified by any national GHG reduction commitment. For this reason, any national commitment on climate change should not only identify the amount of GHG emissions that will be reduced by a certain date, but also the reduction pathway by which these reductions will be achieved.

The following illustration depicts two different GHG reduction pathways for reaching zero emissions by 2050. Although the curve on the top achieves zero GHG emissions at the same time as the curve on the bottom, total emissions during the period are much greater following the emissions reductions pathway under the top curve compared to total emissions under the bottom curve because the lower curve pathway more quickly reduces emissions. Citizens need to understand that waiting to reduce GHG emissions makes the problem worse because waiting consumes more of any shrinking carbon budget that must constrain global emissions to achieve any warming limit goal.

3. No Nation may either Legally or Morally use National Self-interest Alone as Justification for Their Failure to Fully Meet Their Obligations under the UNFCCC.

Because GHG emissions from every country mix rapidly in the atmosphere, all nations’ emissions are contributing to rising atmospheric GHG concentrations thus harming people and ecological systems on which life depends all over the world. The above illustration depicts that the atmosphere is analogous to a bathtub in that it has limited volume and that all nations emitting GHGs are raising atmospheric concentration of GHGs to its current concentration of approximately 407 ppm CO2 (the second line from the bottom in the above bathtub) which level is already causing enormous harm in many vulnerable countries while threatening the entire world if the atmospheric GHG concentration is raised to levels which trip positive feedbacks discussed above (represented by the upper line in the above bathtub). Thus high-emitting countries such as the US may not formulate their climate change policies on the basis of costs and benefits to itself alone. Particularly those nations that are emitting high levels of GHGs must acknowledge and respond to the devastating climate change harms they are already contributing to in other countries and particularly harms to poor people and nations that are most vulnerable to climate change impacts.  Thus in the United States, for instance, the Trump administration’s justification for withdrawing the United States from the Paris Agreement on the basis of “putting US interests first ” is ethically indefensible and tragic because of the damage the Trump climate change policy will cause outside the United States.

The following illustration depicts nations emitting high levels of GHG in red in the top half of the illustration while those countries most vulnerable to climate change impacts are indicated in red in the bottom half of the illustration.

For this reason, as a matter of law, given that nations under the UNFCCC agreed to stabilize GHG concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. (UNFCCC, Art. 2), a nation may not fail to reduce its GHG emissions to its fair share of safe global emissions based on the cost to it because it has ethical and legal duties to other nations not to harm them.

4.  Scientific Uncertainty is Not a Legally or Morally Defensible Justification for Not Adopting Aggressive Climate Change Policy Responses.

Although opponents of climate change policies have justified their opposition on the basis of scientific uncertainty, and despite the fact that the most prestigious scientific organizations have expressly stated their conclusions about the enormous threat of climate change with increasingly higher levels of scientific probability for over 40 years, scientific uncertainty is not a justifiable response for any nation’s unwillingness to adopt climate change policies as a matter of law or morally.

Under international law, including the 1992 United Nations Framework Convention on Climate Change (UNFCCC,  Art. 3.3) which states in relevant part “where there  are threats of serious or irreversible damage, lack of full scientific certainty may not be used as a reason for postponing such measures,” and the “no harm principle”, a principle of customary international law recognized in the Preamble to the UNFCCC, nations may not legally use scientific uncertainty as an excuse for failing to take action to prevent dangerous climate change.

Also as we explained previously in 2008 in The Ethical Duty to Reduce Greenhouse Gas Emissions in the Face of Scientific Uncertainty, nations also have had a strong moral responsibility to take action to reduce the threat of climate change once it was scientifically understood that GHG emissions could cause serious harms even if the harms had not been proven with high degrees of scientific certainty.

Given, that numerous reputable scientific organizations beginning in the late 1970s,  including the US National Academies of Sciences, (See Early Climate Change Consensus at the National Academy) and five reports from the Intergovernmental Panel on Climate Change beginning in 1990 (See IPCC report timeline)  have concluded with increasing levels of certainty that human activities are dangerously threatening people and ecological systems on which life depends, nations have been on strong notice for over four decades that human activities responsible for GHG emissions are dangerous to the human community, thus nations have been on notice about the dangers of climate change for over 40 years and therefore may not legally or morally use scientific uncertainty as an excuse for failing to adopt climate change policies that will reduce their GHG emissions to levels required of them to prevent dangerous climate change.

5. High Emitting Developed Countries, Including the United States, Must Reduce GHG Emissions More Aggressively than Other Countries as a Matter of Law and Practically to Prevent Dangerous Climate Change.

Hiigh-emitting nations have a legal duty under the UNFCCC to reduce their GHG emissions faster than lower emitting nations because they agreed to:

[P]rotect the climate system for the benefit of present and future generations of humankind, on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities. Accordingly, the developed country Parties should take the lead in combating climate change and the adverse effects thereof. (UNFCCC, 1992, Art 3.1)

These principles were re-committed to in the Paris Agreement , Art 2.2 which  provides that:

This Agreement will be implemented to reflect equity and the principle of common but differentiated responsibilities and respective capabilities, in the light of different national circumstances.

Thus under law, hiigh emitting nations, such as the US, have a legal duty under the concept of “equity” to reduce its GHG emissions more rapidly than most other nations.  Although there is reasonable disagreement among nations about what “equity” requires of them,  formulate its ghg emissions reduction target on the basis of equity is not only required by its legal obligations under the UNFCCC, practically the US and other high emitting nations must reduce their GHG emissions by much greater amounts and faster than poor developing nations because if they don’t the poorer nations will have to reduce their GHG emissions almost immediately to near zero CO2 so that global emissions don’t exceed the carbon budget available to prevent a warming limit such as 2 degrees C from being exceeded,

  • There is a basic set of shared ethical principles and precedents that apply to the climate problem…[and] such principles… can put bounds on the plausible interpretation of equity in the burden sharing context…[and] are important in establishing what may be reasonably required of different actors.  (IPCC, 2014, AR5, WG III, Ch. 4, pg .317 )

The IPCC went on to say:

  •  these equity principles can be understood to comprise four key dimensions: responsibility, capacity, equality and the right to sustainable development (IPCC, , AR5, WG III, Ch 4, p. 318).

As a matter of law, therefore, high-emitting countries such as the United States must reduce its GHG emissions to safe levels based on equity at faster levels than other countries as any reasonable interpretation of equity would require the US to make much larger and more rapid GHG reductions than almost all other nations given that the United States (under the concept of responsibility) emitted 5,011,687 metric kilotons (kt) of CO2 equivalent emissions in 2016, second only to China’s 10,432,741 kt CO2. (Netherlands Environmental Agency), also under the concept of responsibility the United States has emitted a greater amount of cumulative CO2 emissions, that is 29.3% of global CO2 emissions between 1850 and 2002, while China emitted 7.6% during the same period, (WRI, Cumulative Emissions) making the US much more responsible for raising atmospheric concentrations of CO2 to the current level of approximately 406 ppm than any country.  Also, under the concept of equality given the US is responsible for 15.56 metric tons per capita CO2 emissions which is more than twice as much as China’s 7.45 metric tons per capita in 2016 (World Bank), as a matter of equity the US must reduce its GHG emissions much more rapidly and steeply than almost all countries.

The following illustration demonstrates why high-emitting nations must also practically reduce emissions more aggressively than other nations because it can be seen that if the high emitting nations such as China, the EU, and USA, depicted near the bottom of the illustration, don’t reduce GHG emissions muchfaster than the rest of the world, and if the international community is going to be restrained by the emissions reduction pathway needed to achieve a warming limit goal, such as the 2 degee C pathway depicted in the illustration, then there is quickly nothing left for the rest of the world. Therefore, high-emitting nations must more aggressively reduce their emissions than lower emitting nations not only as a matter of law but also to retain any hope for the international community to achieve warming limit goals agreed to in the Paris Agreement of as close as possible to 1.5 degrees C but no greater than 2 degrees C.

6. Developed Nations Have a Legal and Moral Duty to Provide Financial Resources to Assist Developing Nartions with both Mitigation and Adaptation Programs and this Financial Assistance is also Practically Indespensible to Prevent Climate-induced Harms in all Countries.

Under the UNFCCC, developed country Parties agreed to provide financial resources to assist developing country Parties in implementing the objectives of the Convention (UNFCCC, Article 4, §3). The Paris Agreement also provides that the developed countries shall provide financial resources to assist developing country Parties with respect to both mitigation and adaptation in continuation of their existing obligations under the Convention. (Paris Agreement, Art, 9.1)

Financial support of developing nation’s mitigation obligations under the UNFCCC  mitigations is not only legally required under the UNFCCC but also practically important because large-scale investments are required to significantly reduce emissions and dangerous climate change will not likely be avoided unless developing nations reduce their GHG emissions to their fair share of safe global emissions. Financial support for developing nations by developed nations is also both legally and ethically required to meet the adaptation needs of developing countries, as significant financial resources are needed by many vulnerable countries to adapt to the adverse climate change.

Climate impacts, such as sea-level rise and more frequent droughts and floods, are already having devastating effects on communities and individuals in developing countries. These impacts on developing countries are already affecting developed nations because, for instance, between 2008 and 2011, approximately 87 million people were displaced due to extreme weather events which is causing a mass migration of refugees which is destabilizing many developed nations, particularly in Europe.(Climate Change in Developing Countries, Government of Canada)  According to the World Health Organization, climate change is expected to contribute to approximately 250,000 additional deaths per year from malnutrition, malaria, diarrhea and heat stress.(World Health Organization, Climate and Health) .

Developing countries are the most impacted by climate change. This is due to many factors, including the economic importance of climate-sensitive sectors for these countries (e.g. agriculture) and the limited financial and human capacity to respond to the impacts of climate change. (Climate Change in Developing Countries, Government of Canada). The Food and Agriculture Organization of the United Nations estimates that by 2030, up to 122 million more people could be forced into extreme poverty due to the effects of climate change—many of them women. (Conflicts Fueled by Climate Change, The Guardian.)

Because climate change is already destabilizing developed countries due to refugees who are fleeing vulnerable areas of poor developing nations that have become inhabitable due to climate change-induced droughts, floods, loss of drinking water, and rising seas, if developed nations do not help finance climate change adaptation programs in developing countries, they will experience growing conflict and stress caused by vulnerable people and refugees in developing countries who are both creating conflicts in their countries and in developed countries they have or are seeking to enter. .

The following illustration depicts the number of  refugees who are fleeing or who have fled climate change.

For this reason, developed country financing assistance for emissions reduction and adaptation programs in developing countries is not only legally required but practically necessary to reduce climate change-induced problems and conflicts in developed countries.

Ethical Issues with Relying on Pricing Carbon as a Policy Response to Climate Change.

I. Introduction.

This entry will examine ethical issues raised by relying on putting a price on carbon as a policy response to reduce the threat of climate change.

Establishing a price on carbon emissions as a response to reduce a government’s greenhouse gas (GHG) emissions has received strong support around the world. One observer of global climate change policy developments has concluded:

Not only is there a robust consensus among economists, but they have been remarkably successful in spreading the gospel to the wider world as well. Climate activists, wonks, funders, politicians, progressives, and even conservatives (the few who take climate seriously) all sing from the same hymnal. It has become conventional wisdom that a price on carbon is the sine qua non of serious climate policy. (Roberts, 2016)

This article will identify potential ethical problems with relying on carbon pricing to reduce the enormous threat of climate change despite the widespread popularity of pricing carbon regimes. As we shall see, although a few ethicists have ethical problems with any carbon pricing scheme, many others approve of carbon pricing schemes provided that the regime design adequately deals with certain ethical issues that carbon pricing regimes frequently raise.

Climate pricing regimes vary greatly from the government to government and among different types of carbon pricing regimes. However, there are two basic methods for using a price on carbon to reduce greenhouse (GHG) emissions.

The first is to distribute carbon caps, often referred to as carbon allowances, to GHG emitters usually followed by a tightening of the cap over time to achieve desired GHG  emissions reduction goals.  Those who have more allowances than they need may sell allowances to those who do not have enough.  Thus carbon allowances may be bought and sold, a scheme that is often justified by economists by claiming that this approach leads to GHG reductions at the lowest cost thereby finding an efficient solution to climate change while the amount`of GHG emissions achieved by the scheme may be determined by the total amount of allowances permitted. This method is usually referred to as “cap and trade”

Many cap and trade regimes allow those who need additional allowances to reduce GHG emissions to levels required by the cap to fund GHG emissions reduction projects often anywhere in the world including in places without a cap and get credit for the amount of GHG reductions achieved by the funded project, which credit then can be applied to determine whether the cap has been achieved. Different trading regimes have different rules specifying where and under what conditions emissions credits can be obtained by funding projects in other places.

The other common carbon pricing scheme is for government to charge a price for carbon emissions, a method usually referred to as carbon taxing. The carbon tax works also to lower GHG emissions because it makes technologies which produce less GHG per unit of energy more attractive thereby creating strong incentives for energy users to switch to energy technologies which produce less GHG emissions per unit of energy produced.  A price on carbon also creates incentives for all those responsible for GHG emissions to do what they can to emit less GHGs, including, for instance, reducing their carbon footprints by driving less, walking more, lowering thermostats in the winter, adding insulation to buildings, etc.

For these reasons, putting a price on carbon emissions as a policy response to human-induced climate change has strong global support particularly among economists.

This article will identify ethical issues created by (a) any carbon pricing scheme, (b) cap and trade regimes, and (c) carbon taxing regimes. This analysis will be followed by several conclusions.

II. Ethical Issues Raised By Any Carbon Pricing Scheme.

Although many ethicists who have identified ethical issues raised by policy responses to climate change that rely on putting a price on carbon acknowledge that pricing schemes have shown to be effective in reducing GHG emissions often at lower costs than other regulatory approaches, some ethicists nonetheless oppose carbon pricing schemes because of certain ethical problems with these schemes. Many other ethicists who acknowledge potential ethical problems with carbon pricing schemes believe these problems can be adequately dealt with by appropriate carbon pricing regime design. Yet even if ethical problems raised by carbon pricing regimes can be averted through carbon pricing regime design, policymakers and citizens need to understand these ethical problems so that they can be mitigated in the design of the carbon pricing scheme.

An ethical approach to climate change would limit GHG emissions by law at levels necessary to prevent human-induced climate change harms to people and ecological systems. For instance, many governments have established legal requirements on the percentage of renewable energy required of electricity providers, a policy response that does no rely on pricing carbon. An ethical approach to climate change is based on different justifications for reducing change harms than some economic approaches. As Vanderhelen said:

An ethical approach to climate policy is based on different assumptions than economic-based policy assumptions. The ethical approach says we should act on climate change now, not because the future costs of inaction exceed those of mitigation, but because the failure to do so harms others. It is our ethical duty to avoid this. (Vanderhelen, 2011)

And so an ethical approach to climate change requires those who are responsible for human-induced climate change harms to comply with their duty to not harm others without regard to the economic value of costs and benefits of climate change policy responses. All national governments in the world have duties to take actions that reduce GHG emissions from their jurisdiction to the nation’s fair share of safe global GHG emissions under the Paris Agreement and the United Nations Framework Convention on Climate Change. 
In addition, an ethical approach to climate change also identifies ethical issues raised by carbon pricing schemes including the following:

A.  Assuring the price will achieve GHG reductions at levels entailed by the government’s ethical obligations.

The amount and speed of GHG emissions reductions that government policies should achieve is fundamentally an ethical question that economic reasoning alone cannot determine. As the Intergovernmental Panel on Climate Change concluded in its 5th Assessment Report:

  • How should the burden of mitigating climate change be divided among countries? It raises difficult questions of fairness, and rights, all of which are in the sphere of ethics. (IPCC, 2014, WG III, Ch. 3, pg. 215).
  • The methods of economics are limited in what they can do. They are suited to measuring and aggregating the wellbeing of humans, but not in taking account of justice and rights (IPCC, 2014, AR5, WG III, Ch. 3, pg.224).
  • What ethical considerations can economics cover satisfactorily? Since the methods of economics are concerned with value, they do not take account of justice and rights in general. (IPCC, 2014,.AR5, WG III, Ch. 3, pg. 225).
  • Economics is not well suited to taking into account many other aspects of justice, including compensatory justice (IPCC,2014, AR5, WG III, Ch. 3,pg. 225).
  • [I]t is morally proper to allocate burdens associated with our common global climate challenge according to ethical principles. (IPCC, 2014, AR5, WG III, Ch. 4, pg. 317).

Thus, no carbon pricing scheme alone without consideration of ethical issues can determine what the magnitude and timing of a government’s GHG emissions reduction goals should be because a government’s GHG emissions reduction goals must be based on fairness, justice, and obligations to not harm others or the ecological systems on which life depends without the consent of those who will be harmed. These are essentially ethical matters that economic rationality alone cannot deal with. Proponents of carbon pricing schemes claim that pricing regimes allow those responsible for reducing GHG emissions to achieve reductions at the lowest cost, yet the amount of reductions that a nation is obligated to achieve is essentially an ethical matter.  So the goal of any pricing scheme should be designed to achieve ethically justified national GHG emissions reduction targets.

All nations in the world have agreed under the 2015 Paris Accord that they are duty bound to adopt policies that will enable the international community to limit warming to between 1.5 degrees C and 2.0 degrees C, the warming limit goal, on the basis of equity and common but differentiated responsibilities and respective capabilities in light of national circumstances, the ‘equity’ requirement under the Paris Agreement.(UNFCCC, Paris Agreement, 2015, Art 2.) And so all nations have an ethical duty to determine their GHG emissions reduction goals which at a minimum would limit warming to as close as possible to 1.5 degrees C although no greater than 2.0 degrees C on the basis of what equity requires of it to achieve these warming limits. Equity is understood by philosophers as a synonym for distributive justice.

Although there are differences among ethicists about what equity requires,  “equity” may not be construed to mean anything that a nation claims it to mean, such as national economic self-interest. As IPCC said, despite ambiguity about what equity means:

there is a basic set of shared ethical premises and precedents that apply to the climate problem that can facilitate impartial reasoning that can help put bounds on the plausible interpretations of ‘equity’ in the burden sharing context. Even in the absence of a formal, globally agreed burden sharing framework, such principles are important in establishing expectations of what may be reasonably required of different actors. (IPCC, (IPCC, 2014, AR5, WG III, Ch. 4, pg. 317).

The IPCC went on to say that these equity principles can be understood to comprise four key dimensions: responsibility, capacity, equality and the right to sustainable development. (IPCC, 2014, AR5, WG III, Ch. 4,  pg 317)

As a result, because some pricing regimes will not reduce national GHG  emissions to levels required by their national obligations under the Paris Agreement even those nations that have adopted some kind of carbon pricing regime have had to enact other climate change policies to achieve the nation’s GHG reduction goals. For this reason and because some politicians have conditioned their support for a proposed carbon pricing scheme on acceptance of legal provisions that prohibit policy responses that are in addition to a carbon pricing scheme under consideration by a legislature, policymakers and citizens need to understand that any carbon pricing scheme must assure that a government’s emissions reduction policies will achieve the government’s ethically determined carbon emissions reduction obligations.  Thus they must oppose legislation that prohibits a government from supplementing carbon pricing schemes with other laws to reduce GHG emissions.

Thus the quantity of the price placed on carbon under a taxing scheme or the magnitude of allowances under a cap and trade regime should be established after express determination of the government’s ethically prescribed obligations to reduce GHG emissions to its fair share of adequately safe global emissions.

Every national GHG emissions reduction target is implicitly a position on two profound ethical questions among others. They are:

  • the amount of warming and associated harms the nation is willing to inflict on others including poor vulnerable people and nations, Since all nations have agreed under the Paris Agreement to limit warming to as close as possible to 1.5 degrees C and no greater than 2.0 degrees C, these warming limits should be the default assumptions of governments’ GHG reduction target formulation;
  • the nation’s fair share of total global GHG emissions that may not be exceeded to keep global warming from exceeding the Paris Agreement’s warming limit goals of 1.5 degrees C to 2.0 degrees C

Thus, to make sense of the acceptability of any carbon pricing scheme, government’s should; (a) identify its GHG reduction target, (b) how the target achieves its GHG emissions reduction obligations in regard to warming limits and fairness, (c) the date by which the target will be achieved, and (e) the reduction pathway that will achieve the GHG reduction goal.

The date by which the GHG reductions will be achieved is ethically relevant because any delay in achieving required reductions affects the remaining carbon budget that is available to assure that any warming limit goal is achieved. Carbon budgets that must constrain global GHG emissions to achieve any warming limit goal such as the 1.5 degrees C to  2.0 degrees C warming limit goals under the Paris Agreement continue to shrink until total GHG emissions are reduced to levels that will stabilize atmospheric GHG concentrations at levels that will not cause warming greater than the warming limit goal. Therefore both the magnitude of the government’s GHG emissions reduction goals and the time it takes to achieve the goal are relevant factors in regard to whether any government will achieve GHG reductions that represent its fair share of safe global emissions. In fact the reduction pathway by which the reduction goal will be achieved is also relevant to whether a government will reduce its GHG emissions to levels required of it by its obligations because pathways which produce rapid reductions early in any period will consume less of a shrinking carbon budget than pathways that achieve most of the reductions at later times in the relevant period.  This fact is depicted in this chart.

This chart demonstrates that different GHG reduction pathways may consume different amounts of any relevant carbon budget even if the percent amount of reductions, in this case, 100% reduction by 2050, is the same for the different pathways. The amount of the budget consumed by the two pathways is represented by the areas underneath the curves.

B. Intrinsic Ethical Problems With Any Carbon Pricing Scheme.

A few ethicists argue that relying on putting a price on carbon to achieve a government’s obligations is ethically problematic without regard to the details of the pricing scheme.

Ethicist Michael Sandel, for instance, in a 1967 OpEd in the New York Times entitled It’s Immoral to Buy the Right to Pollute identified the following ethical problems with pricing carbon after acknowledging that trading GHG emissions allowances could make compliance for the United States cheaper and less painful. (Sandel, 1967)

Turning pollution into a commodity to be bought and sold removes the moral stigma that is properly associated with it. If a company is fined by a government for spewing excessive pollutants into the air, the government conveys its judgment that the polluter has done something wrong. A fee, on the other hand, makes pollution just another cost of doing business, like wages, benefits, and rent. (Sandel, 1967)

The distinction between a fine and a fee for despoiling the environment is not one we should give up too easily. Suppose there was a $100 fine for throwing a beer can into the Grand Canyon, and a wealthy hiker decided to pay $100 for the convenience. Would there be nothing wrong with his treating the fine as if it were simply an expensive dumping charge?

Or consider the fine for parking in a place reserved for the disabled. If a busy contractor needs to park near his building site and is willing to pay the fine, is there nothing wrong with his treating that space as an expensive parking lot?

In effacing the distinction between a fine and a fee, emission trading is like a recent proposal to open carpool lanes on Los Angeles freeways to drivers without passengers who are willing to pay a fee. Such drivers are now fined for slipping into carpool lanes; under the market proposal, they would enjoy a quicker commute without opprobrium. (Sandel, 1967)

Some human behavior is so morally reprehensible that charging a price for the behavior to create a disincentive is widely seen as morally unacceptable. For instance, most societies would agree that a strategy to reduce child prostitution that relies on increasing the price of child prostitution or taxing a sexual transaction in which children are involved is morally unacceptable. Because some countries’ GHG emissions are far greater than any reasonable determination of their fair share of safe global emissions and these GHG emissions are already contributing to the killing or harming millions of people around the world while threatening tens of millions of others, allowing GHG emitters to continue to emit GHGs at unsafe levels if they are willing to pay the price required by a government rather then establishing a legally determined maximum emissions rate consistent with the emitter’s morally determined emissions limits can be argued to be as morally unacceptable as dealing with child prostitution by imposing a tax. Even though a tax might achieve the same amount of reductions as a legal limit implemented by an enforceable cap on GHG emissions amounts, applying a tax implicitly signals that it is morally permissible to continue emitting GHGs at current levels as long as the carbon tax is paid. Thus, the tax can diminish the moral stigma entailed by status quo levels of emissions.

Putting a price on carbon as a policy response to climate change is often justified by economists as a way to make sure that market transactions consider the value of harms caused by climate change that are unpriced in market transactions.  For instance, because the price of coal does not consider the value of the harms caused by the burning of coal that will be experienced by some people who are not participants in the sale of the coal, putting a price on carbon equivalent to the value of the harms caused by the burning of coal is a way of assuring that the value of the harms caused by the coal are considered in the market transaction. This addition to the price is referred to as a Pigovian tax or a tax on any market transaction that generates negative externalities, so that the value of the negative externalities is included in the market price.  Most economists recommend that the amount of the tax be based on the social cost of the negative externalities where the social costs are measured in dollars or other monetary units determined by the amount people would be willing to pay to prevent the harm. Once the cost the harms is determined and included in a tax, the market will be able to operate efficiently.

Economists thus justify a tax set in this way because it enables the market to maximize preferences. But ethics is interested not in maximizing preferences people have but in assuring that people’s preferences are those that people should have morally.  For ethicists, it is wrong to harm people without their consent, even if those causing the harm could pay victims money calculated by the market value of the harm. That is, according to most ethicists it is morally wrong to harm people or the ecological systems on which life depends even if those causing the harm are willing to compensate those harmed. Some ethicists therefore argue, putting a price on carbon as a policy response to climate change does not pass ethical scrutiny unless the price prevents all non-trivial harms to life, health, and ecological property that people have not consented to. Given that some human rights have already been demonstrated to be violated by climate change (UNHR, 2018), any price on carbon that allows human rights violations to continue does not pass ethical scrutiny.

And so putting a price on carbon does not pass ethical scrutiny as long as the price does not prevent the harms that people have right to object to without their consent.

Although the money from the carbon tax could be used to compensate people for harms caused by climate change, this potential use of the tax revenues does not ethically justify continuing the behavior which causes serious harms to others without the consent of those who are harmed. In addition, because those being harmed by GHG emissions are people all around the world, if the revenue from a tax is to be used to compensate those who will be harmed by the GHG emission, the revenues from a tax would have to be distributed worldwide.  At this time there is no such global revenue stream from national carbon pricing schemes.

Many citizens and institutions around the world including many colleges and universities have significantly reduced their carbon footprint because they believed they had a moral obligation to do so as long as their GHG emissions could contribute to harming people, animals, ecological systems on which life depends, or things of great value to people.  A sense of moral obligation, without doubt, motivates, at least some people and institutions, to do the right thing. Yet pricing carbon as a response to climate change does not create a legal prohibition to reduce GHG emissions but only an economic incentive to do so.  A government could always legally prohibit activities that create GHG emissions that create harms, an approach to changing behavior that was the dominant strategy in environmental law for many decades. Economists, however, have often objected to these “command and control’  approaches because they claim that market-based mechanisms can achieve needed reductions in a more efficient economic way, that is, at a price that includes consideration of the value of the harms created.

At least in the United States, many of the proponents of carbon pricing are failing to educate civil society about the moral obligations of all nations and people to reduce GHG emissions to their fair share of safe global emissions, a concern particularly in light of the very limited time left to limit warming to non-catastrophic levels. These proponents often passionately advocate for the adoption of a carbon pricing scheme because they are accurately convinced that a price on carbon will reduce GHG emissions, yet ignore discussing the non-discretionary moral duty to reduce GHG emissions thus inadvertently leaving the impression that provided that those who are willing to pay a price placed on carbon they have no moral obligation to cease activities which are responsible for carbon emissions. 

Economists often justify their market-based solutions as a method for maximizing the enjoyment of human preferences.  They thus calculate the value of harms avoided by climate policies by determining a market value of the harm and if there is no market value they often determine the value of the harms by determining what people are willing to pay to prevent the harm. This allows the economists to compare the cost of reducing GHG emissions against the value of harms prevented through pricing and in so doing allows a policymaker to select a policy option which maximizes human preferences. Yet, as we have seen ethics is concerned not solely with efficiently achieving the preferences people have but with establishing what preferences people should have in light of their moral obligations.

Under an ethical approach to climate change based on an injunction against harming others, because any additional GHG are raising GHG atmospheric levels which are already increasing harms people are suffering from droughts, floods, intense storms, tropical storms, and heat waves among other causes of  climate-induced harms, an ethical argument can be made that any carbon pricing scheme should seek to achieve the lowest feasible GHG emissions levels as quickly as possible. Ethics refuses to define what is ‘feasible’ in terms of the balance of costs and benefits. Ethics requires that harm to innocent victims must be avoided, even when the cost of reducing pollution exceeds the monetary value of harms to life and ecological systems on which life depends. Not all economists, of course, argue that government policies should be based on cost-benefit analysis but many do.

An ethical approach to climate change also requires that polluters should pay for the harms and damages they create as well as the costs to them of reducing the pollution.  Many carbon pricing schemes ignore the duty of GHG emitters to compensate those who have been harmed by their GHG emissions and base the amount of the tax on the amount of money needed to reduce GHG emissions while ignoring any obligations to compensate those who have been harmed by their emissions. This problem could be remedied by basing any price on the amount of money needed to compensate those who have experienced loses and damages or by providing separate funds to compensate those who are harmed by climate change but most carbon pricing schemes fail to take these matters into consideration.

Ethicists also acknowledge that climate-related harms are more likely to affect the poor, not just those who are now being asked to contribute toward its mitigation. For this reason, many ethicists prefer laws that prohibit certain immoral behaviors over laws that allow people to continue their immoral behavior if they are willing to pay higher prices entailed by the value of the harms caused by their behavior.

Economists often support pricing schemes if the pricing leads to the market incentivizing the use of alternative technologies that don’t create the harms of concern. In such cases, the morality of the pricing scheme likely depends on whether the technical transformation created by the pricing scheme will take place soon enough to prevent the harms of concern.

However, even in these cases, many ethicists believe that human activities that create morally unacceptable levels of GHG emissions should be responded to as moral obligations and only support pricing schemes so long as the scheme will enable reducing GHG emissions to morally acceptable levels as rapidly as possible. However, even so, some ethicists warn against erasing the moral stigma entailed by morally unacceptable levels of GHG emissions that could occur by allowing some to continue to exceed their moral obligations if they are willing to pay to do so.

Pope Francis in Laudato Si, the papal encyclical released in July 2015, questions whether market capitalism can effectively protect the poor, and in one passage specifically criticized “the strategy of buying and selling ‘carbon credits.’ More specifically Laudato Si argues that:

The strategy of buying and selling ‘carbon credits’ can lead to a new form of speculation which would not help reduce the emission of polluting gases worldwide. This system seems to provide a quick and easy solution under the guise of a certain commitment to the environment, but in no way does it allow for the radical change which present circumstances require. Rather, it may simply become a ploy which permits maintaining the excessive consumption of some countries and sectors. (Laudato Si 171).

The Pope’s objection appears to be based in part on the fact that a carbon pricing scheme will allow those who can afford to continue emitting GHGs after paying the pricing fee to do so while those that are unable to afford to pay the fee will need to reduce the activities that create GHG emissions. Yet this problem can be somewhat ameliorated by carbon pricing regime design decisions on how revenues are distributed or how allowances to emit are allocated.  However, these decisions raise questions of distributive justice, that is questions about how burdens or benefits of public policy should be allocated to comply with what fairness requires. For this reason, carbon pricing schemes often raise serious questions of distributive justice.

In addition if revenues from pricing schemes are to be used to help compensate those who are most harmed by climate change, given that those who are most harmed are often very poor people in poor nations that usually have done little to cause climate change, the revenues would need to transferred to poor nations and people around the world. Yet no national carbon pricing schemes have yet proposed such international financial transfers.

III. Ethical Issues Raised by Cap and Trade GHG Emissions Reduction Schemes

This paper next examines the following ethical issues raised by cap and trade regimes that are additional to those discussed in Section II.

A very detailed examination of some ethical issues raised by cap and trade regimes by Simone Carey and Cameron Hepburn is entitled Carbon Trading: Unethical, Unjust, and Ineffective? The Carey/Hepburn paper discusses in detail the following ethical issues raised by cap and trade regimes that are in addition to those discussed above. The following is a summary of issues discussed by the Carey/Hepburn paper.

A. Rights to use nature cannot be owned

Because GHG emitters that receive allowances or buy allowances from those that have excess allowances could under some trading mechanisms hold or bank these allowances, holders of allowances could be understood under some trading schemes to have a right pollute the atmosphere at levels entailed by the allowances they hold. However, most ethicists believe that no one should have a property right to pollute the atmosphere.  Because in absence of a rule that would prevent the owner of allowances to bank the allowances for use far into the future, the owners of the allowances could accumulate the right to pollute far into the future. As a result, some ethicists have argued that allowances should be limited to a specific time period and be understood to be revocable if the science changes and concludes that greater reductions are necessary then those that were understood to be necessary to prevent harm when the allowances were distributed.

B  Responsibilities to abate harms cannot be transferred to others

Some ethicists believe that some human responsibilities should not be allowed to be transferred to others. For instance, it is generally believed to be ethically unacceptable for those who are potentially subject to being drafted into the military to be able to buy their way out of this obligation by paying someone else to agree to take one’s place if he or she is drafted. For this reason, some ethicists claim that is ethically problematic for high GHG emitters to get a credit for reductions made by others while not requiring more of the high emitters to reduce their emissions.

C. Distributive justice issues with how allowances and revenues are allocated

Because those with the money to do so can buy scarce allowances, participants in a cap and trade regime can wind up with vastly unequal levels of allowances creating significant differences among participants in rights to emit GHGs. In addition, because rules determining who can get allowances and what is done with the money generated from allowance trading can create great imbalances, rules for allocating allowances and revenues from sales of allowances should be consistent with what distributive justice requires to assure fair burden and benefit sharing. Distributive justice requires that people should be treated equally unless there are morally relevant reasons for treating people differently. There is no reason in principle for allowance and revenue allocations to lead to a more unequal distribution of wealth. It will depend on how the cap and trade scheme is designed.

These issues are discussed in more detail by the Carey/Hepburn paper.

D. Ethical issues created by the fact that some cap and trade regimes allow high emitters of GHGs to count emissions reductions made by projects of others funded by the emitters in achieving the high emitters’ GHG reduction obligations.  

Some cap and trade regimes allow those with GHG emissions reduction obligations to count the reduction of GHG emissions made by others’ projects funded by the emitter as a credit in achieving the emitter’s cap obligations. Economists justify this feature of cap and trade because it allows emitters to achieve GHG reductions at a lower price, However, not all GHG reduction strategies will reduce GHG emissions with equal probabilities that GHG reductions made by the emitter would actually have achieved. For instance, an electricity supplier can commit to reducing its emissions to amounts that will be achieved with high levels of confidence by installing non-fossil energy but if the electricity supplier relies on funding a forestation project in a third world country to obtain a credit for its emissions reductions. the actual reductions to be achieved by the funded project are much more speculative because of problems in assuring that any forest project will keep GHG reductions achieved by photosynthesis of the forest out of the atmosphere forever. Thus funding a project to achieve GHG emissions credits raises issues about the reliability of achieving specific GHG emission reduction amounts that are more reliable if the person responsible for GHG emissions must assure that GHG emissions will actually be achieved.

Thus cap and trade regimes often also raise the following ethical problems which were discussed in more detail in a prior entry on this website. (Brown, Ethical Issues Raised By Carbon Trading, 2010).:

a. Permanence. Many proposed projects for carbon trading raise serious questions about whether the carbon reduced by a project will stay out of the atmosphere forever. Yet permanent storage of carbon is needed to assure equivalence between emissions reductions avoided if no credits were issued and atmospheric carbon reductions attributable to a project which creates carbon credits. This is so because emissions reductions should guarantee that some quantity of GHG will not wind up in the atmosphere, yet some projects which are used to substitute for emissions reductions at a source have difficulty in demonstrating that the quantities of carbon reductions projected will actually be achieved. For instance, carbon stored in forests, soils, or geological carbon sequestration projects could be released to the atmosphere under the certain conditions. For example, rapid temperature change could kill trees thus releasing back into the atmosphere carbon stored in the trees. This problem is usually referred to as the problem of “permanence” of carbon reduction projects. For this reason, only projects that assure permanent reduction of carbon in the atmosphere can be categorized as environmentally effective projects and should be used to offset activities which actually release carbon.

b. Leakage. Many proposed projects for carbon trading raise serious questions about whether carbon reduced by a project at one location will result in actual reductions in emissions because the activity which is the subject of the trade could be resumed at another location. For example, paying people to plant trees in location A is not environmentally effective if these same people that receive the money chop down trees at place B. This is the problem usually referred to as “leakage.” Forest and other kinds of bio-sequestration projects that sequester carbon in particular often create leakage challenges. Industrial projects can also create leakage problems if the industry gets credit for reducing carbon at one industrial plant while moving the carbon producing activities to another place. If leakage occurs, then the trade is not environmentally effective.

c.  Additionality. Getting a credit for a project which is used in a trade will also not be environmentally effective if the project would have happened anyway for other reasons. This is so because trading regimes usually assume that a GHG emitter should get credit because of their willingness to invest in projects that reduce carbon emissions that would not happen without the incentive to get credit for carbon reductions. If the project would happen without the investment of the emitter, then the investment in the project is not “additional” to business as usual. This is the problem usually referred to as the “additionality” problem.

d.  Enforcement of trading regimeA trading regime is environmentally ineffective if its conditions cannot be enforced. Although enforcement of trading regimes is sometimes practical when the project on which the trade is based is within the jurisdiction of the government issuing the allowances, enforcement is particularly challenging when the project is located outside of allowance issuing government. In such cases, enforcement must be “out-sourced” to other institutions or governments In addition, while many hundreds of millions of dollars are being invested in setting up emissions trading schemes all over the world, virtually no resources are being channeled into their enforcement or verification. Although most cap and trade regimes have built-in carbon reduction verification steps, verification remains extremely difficult for many types of carbon reduction projects for which credits are being issued because of the lack of enforcement or long-term verification potential. This enforcement challenge is exacerbated when projects for which credits are issued are in poor countries without the technical capability to enforce or verify that reductions have been made. Because of this, a strong case can be made that those who desire to rely on projects that have dubious enforcement and verification potential should have the burden of demonstrating enforcement and verification potential before they may obtain credits generated from these projects.

 e. Distributive justice and internal allocation of a government-wide cap. How a cap is allocated among entities within a government creates many potential distributive justice problems. Governments sometimes distribute a cap they have by giving away allowances, auctioning allowances, and other ad hoc considerations that often take into account political feasibility. Each of these methods of distributing a cap raises distributive justice issues that are often ignored for political reasons. For instance, both auctioning allowances and giving away allowances could be significantly regressive, making higher-income households better off while making lower-income households worse off. Auctioning could also be regressive if the most wealthy get the most permits forcing those without the financial resources into non-polluting options. Sometimes governments choose to allocate the cap by placing caps on “upstream” carbon users such as coal and petroleum companies and ignoring “downstream” carbon emitters such as coal-fired industrial users. A decision to place a cap upstream makes the climate change regime easier to administer but could have regressive effects on those least able to afford increased fuel costs. An upstream cap also can create little incentives for those who can afford to waste energy to change behavior. In contrast, downstream caps puts the responsibility on energy users. There is no ethically neutral way to decide these design questions.

f. Distributive justice and revenue from allowancesWhen allowances are auctioned or otherwise purchased, governments must make decisions about how to use allowance revenues. These decisions raise a host of distributive justice issues that are often ignored for political reasons. Some governments have chosen, for instance, to use allowance revenues to fund climate change technology research, to meet international obligations to fund climate change adaptation projects in developing countries, to fund programs to reduce deforestation projects in developing countries, to buy off politically powerful opponents to climate change legislation, to help those least able to cope with rising energy costs, or to subsidize nuclear power, geologic carbon sequestration, or renewable energy.  Thus, decisions about how to allocate revenues from distributing allowances raise distributive justice issue

IV. Ethical Issues With Carbon Taxes.

In addition to the ethical issues that apply to all carbon pricing regimes identified in section II of this entry, carbon taxing regimes can raise the following additional ethical issues.

a. Distributive Justice and a Carbon Tax.  Carbon taxing regimes must decide who must pay the tax and just as is the case for cap and trade regimes in the allocation of allowances, taxing schemes may choose to apply the tax either to upstream producers of carbon fuels such as petroleum or coal companies that distribute fossil fuels or further downstream to entities such as electricity generators who consume the fossil fuels. Upstream taxation creates fewer taxable entities who have a huge tax burden. Therefore the decision on who to tax creates different winners and losers, an outcome which has political significance particularly in places where fossil energy is mostly produced. If the tax is based on the amount of CO2 per unit of energy, then some fossil fuel industries such as coal production will pay a much higher tax per unit of energy, a fact which most greatly affects those places and communities that produce fuels with higher CO2 emissions levels per unit of energy.  This fact creates heavy burdens from the tax for those who are dependent on the sale of fuel with higher CO2 production levels. And so a decision about who must pay a tax has distributive justice implications.

How the tax revenues are used by the government also has enormous political and distributive justice implications. Policymakers are faced with many competing ways of using tax revenues generated by putting a price on carbon.  Many parts of the world that have established a carbon tax use it primarily to subsidize technologies that produce lower amounts of GHG per unit of energy such as wind and solar power. Other governments use the revenues to ease the burden on those who are most affected by the tax, including poor people. Thus how the revenues of a carbon tax are distributed raises deep questions of distributive justice which also create issues of political feasibility.

b. Amount of the tax. 

As we have seen all carbon pricing schemes raise ethical issues about whether the price is sufficient to achieve GHG emissions reductions consistent with the government’s ethically determined obligations to reduce GHG emissions. A pricing  regime that is based on taxing carbon emissions raises more challenging questions about whether the tax is ethically stringent enough than cap and trade regimes because governments are able more easily assure that the cap is stringent enough than a regime based on taxing carbon because the size of the cap may be set directly on the magnitude of GHG reductions required for the government to achieve its ethically determined GHG emissions reductions obligations while the sufficiency of a tax must rely on economic modelling to determine the magnitude of reductions that will be achieved by different levels of the tax. Determining the amount GHG reductions that will be achieved by different levels of the tax is always somewhat of a guessing game due to the inherent imprecision of economic modeling to predict how entities and people will respond to different price signals. For this reason, taxing schemes that seek to assure that the government will reduce GHG emissions reductions levels congruent with the government’s ethically determined reduction obligations should include accelerator provisions that would increase the amount of the tax once it is determined that actual GHG reductions are not consistent with reductions pathways required to achieve ethically determined reductions obligations. However, because experience with carbon taxing programs around the world has demonstrated that political backlash will likely arise that undermines government support for continuing a carbon tax that is judged to be too high, governments which seriously seek to reduce their GHG emissions through imposing a tax alone may need to consider back up strategies rather than rapidly accelerating taxes if the original tax does not achieve the GHG reductions required of it by its ethical obligations.

c. Considering responsibility for prior emissions, an issue relevant to distributive  justice. 

Distributive justice supports an allocation of burden sharing obligations on the basis of who is most responsible for causing the current problem. Carbon tax regimes are usually forward-looking; in that most schemes make everyone pay the same price for using the atmosphere’s capacity to absorb CO2.    Thus the scheme ignores responsibility determined by looking backward at questions such as:

  • Who caused the problem?
  • Who benefited from past emissions?
  • Who is in the best position to fix the problem?

To deal with these questions, a carbon tax may need to be supplemented by additional policies, for example by tax credits for poor people or sharing of tax revenues with those who must pay the tax but who have done little to cause the current problem so that the tax scheme can consider the distributive justice implications of looking backward at who is most responsible for the current problem

V. Conclusions.

As we have seen carbon pricing schemes designed to reduce GHG emissions raise a host of ethical issues and problems.

Although many of these ethical problems can be dealt with by the pricing carbon regime design, given the enormous threat to life and ecological systems created by human-induced climate change, perhaps the most important ethical issue raised by carbon pricing regime is whether the carbon pricing regime will be successful in reducing a government’s GHG emissions to its fair share of safe global emissions.

Because there is limited political support for enacting carbon pricing schemes with sufficient pricing levels to achieve the enormous reductions in GHG emissions now necessary to prevent very dangerous climate change, carbon pricing schemes will likely require policy responses in addition to carbon pricing alone.

Because of the need to judge whether any carbon pricing scheme will achieve a government’s ethically determined GHG emissions reduction obligations, all proposed carbon pricing schemes should be clear and transparent on how the pricing scheme will achieve the government’s ethically determined GHG reduction goals. A pricing scheme could contribute to achieving a nation’s GHG reduction obligations either by establishing a price that will sufficiently reduce a government’s GHG emissions to achieve the nation’s GHG reduction obligations by itself or in combination with other GHG reduction policies. However, to judge the adequacy of the pricing scheme, governments should explain the role of any carbon pricing scheme in achieving its ethically determined GHG reduction obligations.

COMMENTS

The following comments on this entry were made by Eric Haites, an economic consultant for Margaree Consultants Inc, in Toronto

 

Ethical Issues Entailed by Pricing Carbon as a Policy Response to Climate Change confuses benefit-cost analysis with carbon pricing and criticizes carbon pricing on grounds that also apply to non-price policies.

Carbon pricing policies – cap and trade systems (CTSs) and carbon taxes – are regulatory measures to limit greenhouse gas emissions (GHGs) by specified sources within a jurisdiction. They may be implemented in conjunction with or as substitutes for non-price regulations such as subsidies for non-carbon energy, minimum gasoline efficiency standards for vehicles, funding for affordable public transportation, requirements/incentives to increase the supply of renewable energy and energy efficiency standards for buildings.

Benefit-cost analysis of climate change compares the estimated costs of different levels of global emissions reductions with the estimated value of reduced global climate change damages associated with those emission reductions. Benefit-cost analysis of climate change is extremely complex conceptually and in practice. Since the analysis must span a century or more due to the long atmospheric lives of greenhouse gases, the calculations are very sensitive to the discount rate and have large uncertainty ranges.

A CTS or carbon tax can be implemented by a jurisdiction to help achieve its GHG reduction goal regardless of how that goal is established. A country that has a nationally determined contribution under the Paris Agreement can use carbon pricing and/or non-price policies to meet its commitment.

It is true that many economics textbooks suggest that the carbon tax be set at the level determined by benefit-cost analysis, but that is not necessary and is based on the implicit assumption that an emissions reduction goal has not been established by other means, such as international negotiations.

Many of the criticisms of carbon pricing policies do not specify an alternative policy. If emissions are to be reduced, the alternative is a set of non-price regulations including efficiency standards and increased reliance on renewable energy. In practice, neither carbon pricing nor non-price regulations cover all GHG emissions, so there are regulated emissions and exempt emissions under every policy.

Consider then the claim that it is immoral to buy the right to pollute. Before a regulation is implemented, the right to pollute in unlimited quantities is free. Regulations impose costs and/or quantity limits on the right to pollute. In the case of a carbon tax, there is a cost for each ton of GHGs emitted by specified sources. In the case of a CTS, total emissions by specified sources are capped. In the case of non-price regulations there is a compliance cost, but any remaining emissions are free and unrestricted. The cost of an efficient automobile is higher, but its emissions are not priced or restricted.

One of the arguments by Simone Carey and Cameron Hepburn cited by the paper is that the rights to nature can not be owned. Many CTSs explicitly state that the allowances are not property rights. Almost all of the CTSs have cancelled or greatly devalued surplus allowances.

In the paper, the discussion of the distinction between a fine and a fee is misleading for a CTS. Every CTS has penalties for non-compliance, so the correct comparison is the fine for a CTS and that for a non-price policy. The non-compliance penalty for most CTSs is a reduction in emissions equal to the exceedance plus a penalty. To use the analogy in the paper, a CTS requires the offender to pick up the beer can and pay a penalty. In contrast, a non-price regulation only imposes a fine.

The paper raises the concern that “the tax can diminish the moral stigma entailed by status quo levels of emissions.” Why would the moral stigma associated with residual emissions differ? Are the residual emissions by a source subject to a carbon tax morally less acceptable than those by the owner of a more efficient automobile. Sources subject to carbon pricing policies have a financial incentive to make emission reductions that cost less than the tax/allowance price. Sources subject to non-price policies have no incentive to reduce their emissions.[1]

Issues of distributive justice arise for all regulations; which sources are regulated, how stringent is the regulation, how should groups that are adversely affected by compensated? The paper clearly identifies these issues for CTSs and carbon taxes. But they apply equally to non-price regulations. Who pays for the more efficient vehicles and buildings, the public transit and the additional renewable energy? Those costs will be borne by specific groups or the government. Carbon pricing policies have the advantage that they generate revenue that can be used to help address distributive justice.

The paper argues that past emissions should be considered when addressing distributive justice. Presumably, this consideration applies to any policy, not just carbon pricing. In practice the ability to do this is limited due to lack of data and the long atmospheric lives of GHGs. Non-price regulations often differentiate between existing and new sources and CTSs address this concern through their allowance allocations.

In summary, carbon pricing can be implemented by a government to help meet its GHG emissions reduction target regardless of how that target is established. A CTS or carbon tax can be implemented alone, jointly or in combination with non-price policies. In practice all jurisdictions with a pricing policy also implement non-price policies. Many of the ethical criticisms of pricing policies apply to non-price policies as well. Price policies have the advantage of raising revenue that can be used to address distributive justice.

[1] Indeed, they may have a financial incentive to increase emissions. A more efficient vehicle may have a lower operating cost per km so the owner may drive more.

Resonse to comments

I agree that levels of GHG reductions achieved by a pricing scheme need not be determined by Cost-Benefit Analysis although some economists recommend this. In such cases the ethical issues discussed in this paper apply

Mr, Haite is correct that the articles criticism of carbon pricing schemes may also apply to other responses to climate change, However, if the level of reductions that constitute a nation’s GHG reduction target are based on a nation;s ethical obligations, then the problem entailed by some carbon pricing scheme’s allowing emitters to continue emit as long as they pay  a tax is not possible.

 

Why Overcoming Instrumental Rationality In Climate Change Policy Controversies Is a First Order Problem Preventing Ethical Principles From Getting Traction to Guide Climate Change Policy Formation

 

I. The Failure of Ethical Principles to Get Traction in Climate Change Policy Formation.

This entry will explain why a type of rationality, referred to as instrumental rationality, both dominates policy formation on climate change around the world and is responsible for the failure of ethical principles to guide government responses to climate change.

As we have explained frequently on Ethicsandclimate.org, climate change is a problem with features that particularly require that it be seen and responded to as an ethical problem even more than other environmental problems. These features include that: 

  • First, it is a problem that is being caused by some people in one part of the world who are putting others in other places who have often done little to cause the problem at great risk. 
  • Second, the harms to those at most risk are not mere inconveniences but potentially catastrophic harms to life and natural resources on which life depends.  In fact, unless humans adequately respond to climate change’s growing threats, most of life on Earth is threatened.
  • Finally climate change is a problem about which many of its greatest victims can do little to protect themselves by petitioning their governments for protection. The victims’ best hope is that the those high-emitting nations and people causing the problem will see that they have duties to climate change victims to avoid harming them.

The ethical dimensions of climate change are important to understand because unless those nations and individuals that are emitting high levels of greenhouse gases (GHGs) reduce their emissions in accordance with their ethical obligations, climate change will  eventually cause great harm to all but particularly to those who are most vulnerable to climate change impacts and who usually have done little to cause the great harm. 

There are many ethical principles that should, without controversy, guide national responses to climate change. These include, for instance:

  • Governments around the world have agreed under the 1992 United Nations Framework Convention on Climate Change (UNFCCC, 1992) and agreements by parties under this treaty since then, including the Paris Agreement (Paris Agreement 2015), to adopt national climate change policies on the basis of several ethical principles including the duty to establish national policies in accordance with equity and common but differentiated responsibilities (UNFCCC, 1992, Art 3.1), to apply the precautionary principle that prohibits nations from using scientific uncertainty as an excuse for not taking action to prevent dangerous anthropocentric interference with the climate system (UNFCCC, 1992, Art 3.3), and the principle that developed countries have the obligation to take the lead on reducing the threat of climate change (UNFCCC,1992, Art 3.1), and to enact policies that limit warming to between 1.5 to 2.0 degrees C (United Nations, 2015 Art 2)
  • In addition there are numerous other non-controversial ethical norms that are understood to apply to nations as a matter of international law to global environmental problems such as climate change including the “no harm principle” which obligates nations to prevent people or entities within their jurisdiction from harming people and nations outside their borders (UNFCCC,1992, Preamble), and the “polluter pays principle” which requires those nations causing harm from pollution to pay for the damages they cause (Rio Declaration, 1992, Principle 16).

Yet most nations are completely ignoring these ethical obligations when they formulate policy responses to climate change (National Climate Justice. Lessons Learned).

A research project led by Widener University Commonwealth Law School and the University of Auckland found that despite express national promises under the Paris Agreement to base national climate commitments known as Nationally Determined Contributions (NDCs) to reduce the threat of climate change to prevent warming as close as possible to 1.5°C but no more than 2°C, on the basis of equity and common but differentiated responsibilities, all 24 nations studied actually set their NDCs on economic self-interest. Yet this conclusion was not determinable from the documents that nations submitted to the UNFCCC Secretariat when the nations submitted their NDCs (National Climate Justice, Lessons Learned). The study also found that environmental NGOs in the country that supported national action on climate change did not seem to understand how to critique the failure of the nation to set its NDC on the basis of the nation’s ethical obligations including ethical obligations that the nation expressly agreed to.

Every national commitment to reduce greenhouse gas (GOHG) emissions, or NDC, is implicitly a position on two profound ethical questions among others. They are:

  • the amount of warming and associated harms the nation is willing to inflict on poor vulnerable people and nations, and
  • the nation’s fair share of global GHG emissions that may not be exceeded to keep global warming from exceeding a warming limit goal.

Yet nations around the world are setting their NDCs on economic self-interest and ignoring their ethical responsibilities on these issues.

Although reasonable people may disagree on what equity requires of nations to reduce their GHG emissions, national economic self-interest as a justification for their GHG reduction targets does not pass minimum ethical scrutiny. In this regard the Intergovernmental Panel on Climate Change (IPCC) said its fifth assessment report that despite ambiguity about what equity means:

There is a basic set of shared ethical premises and precedents that apply to the climate problem that can facilitate impartial reasoning that can help put bounds on the plausible interpretations of ‘equity’ in the burden sharing context. Even in the absence of a formal, globally agreed burden sharing framework, such principles are important in expectations of what may be reasonably required of different actors. (IPCC, 2014).

The IPCC went on to say that these equity principles can be understood to comprise four key dimensions: responsibility, capacity, equality and the right to sustainable development (IPCC, 2014).

And so ethical principles are failing to guide national climate change policy formation despite the uncontroversial applicability of several ethical principles that should guide national climate change policies.

The failure of ethical principles to get traction in guiding policy is a much broader problem than in regard to climate change policy formation alone.  Despite the emergence of the academic sub-discipline of environmental ethics in the late 1970s, ethical principles are failing to influence environmental policy-making for most environmental problems.

The claim that ethical principles are rarely guiding environmental policy formation is strongly supported by the comments of the founder of the journal Environmental Ethics, Eugene Hargrove, who in 2003 published an essay “What’s Wrong ? Who’s to Blame? (Hargrove, 2003). This essay invited reflection on why environmental ethics has not had an influence on environmental policy.  Just three years later, Robert Frodeman, in the  same journal in an article entitled “The Policy Turn in Environmental Ethics” also reflected on the huge failure of environmental ethics to achieve traction in environmental policy formation (Frodeman, 2006).

Since its inception in the late 1970s, academic environmental ethics has been mostly focused on theoretical issues while completely failing to help policy makers understand what is ethically wrong with specific arguments made by opponents of environmental policies who almost always use arguments derived from instrumental rationality which hide dubious unstated norms that are the justification for the arguments and which would often fail minimum ethical scrutiny if the norms were made express and critically reflected on.

One of the reasons why ethical principles have failed to affect environmental policymaking is the failure of the academic discipline of environmental ethics to pay attention to actual controversies that arise in environmental policymaking debates. Academic environmental ethics since its inception in the late 1970s has been almost exclusively focused on theoretical issues, such as how to ground a biocentric or ecocentric ethics, while completely failing to help policymakers understand what is ethically wrong with specific arguments made by opponents of environmental policies who almost always rely on arguments derived from instrumental rationality which hide or ignore dubious unstated norms on which the arguments are based. 

II. The Problem of Instrumental Rationality

This article now explains why a first order task that needs to be addressed before ethical principles can play their appropriate role in shaping environmental public policy is to open policymaking arguments on environmental issues including climate change to express ethical reflection. This is a first order task because throughout the world those responsible for environmental policymaking are following instrumental reason, a mode of reason which hides or ignores ethical questions, to determine the acceptability of environmental policies. It is a first order problem because before one can consider what ethical principles should guide policy formation, policymaking must be made open to ethical critique and reflection. If policymakers don’t see and respond to the ethical issues that are implicitly raised by arguments raised against proposed policies, they can’t apply the appropriate ethical rules.

Instrumental rationality is a mode of rationality that is exclusively concerned with the search for efficient means or scientific facts which, consequently, is not concerned with assessing the goals—or ends— that policies should pursue. This form of rationality has existed throughout history, but has become increasingly more dominant in post-Enlightenment liberal democratic capitalist societies (Cruickshank,2014).

Ethics rationality, on the other hand, is concerned about what the goals of society should be. Ethical reasoning seeks to determine what should be the goal of human behavior by examining what is right or wrong, what is permissible or impermissible, what actions are obligatory or non-obligatory, and how burdens of preventing harm should be justly distributed.

Instrumental rationality, because it focuses on means, usually ignores ethical questions about what the goals of policy should be despite the fact that every argument against a proposed environmental policy already contains an unstated norm.  For instance, a claim that a proposed climate change policy should not be adopted because it imposes unacceptable costs rests on the unstated norm that the government should not adopt policies that impose significant costs on the economy or specific industries.

Scientific and economic reasoning, which have increasingly dominated public policy-making from the beginning of the Enlightenment, almost always focuses on how to achieve goals, not on what goals or ends should be desired.

Economic rationality often focuses on how to maximize human preferences. Ethics asks a different question of economic activity, namely what preferences humans should have.

Scientific reasoning usually tests hypotheses to determine what “is.”  Moral philosophers believe that determining what “is,” which is the proper domain of science, cannot determine what “ought” to be, which is the domain of ethics.

Yet instrumental rationality that scientists and economists deploy in their search for scientific and economic facts has dominated public life and higher education for several centuries.

That instrumental rationality dominates environmental policy making is clear given that most government environmental agencies are staffed exclusively by engineers, scientists, economists, and lawyers but very infrequently by employees trained in ethics. This is huge problem because very few employees of environmental agencies or scientific organizations that make policy recommendations can spot problematic ethical issues that should be acknowledged in policy debates and particularly ethical issues that are ignored or hidden when instrumental rationality is deployed to make policy recommendations. Although employees of government agencies responsible for policy formation often understand they should apply policy rules entailed by relevant laws, many relevant laws do not contain clear rules on how to respond to economic and uncertainty arguments against proposed environmental policies.

Instrumental rationality dominates public policy formation for at least two reasons:

First, sociologists, including Max Weber, have predicted that instrumental rationality would over time crowd out ethical rationality in modern societies because increasingly complex human problems would be relegated to bureaucracies run by technical experts whose expertise depends on the use of instrumental rationality. Since the power of experts depends, in part, on maintaining the fiction that their expertise is the central key to solving modern problems, these experts are reluctant to acknowledge that their analytic tools for solving problems are often ethically inadequate and sometimes ethically inappropriate (Thomas, 2017). Moreover particularly in capitalist societies, wealthy interests are able to hire experts and frequently do so to fight government action which would reduce profits.

Second, opponents of proposed environmental policies usually frame opposition to these policies on the basis of excessive costs to governments or specific industries or lack of scientific certainty about harms the policy seeks to prevent. These arguments very frequently hide controversial normative assumptions implicitly embedded in the arguments. For instance, cost arguments made in opposition to environmental policies often rest on the very ethically dubious idea that any policy which creates significant cost to a nation, regional economy, or to a specific industry should not be adopted even when the problematic behavior causes serious harm to people or nations who have not consented to be harmed.  The public debate in response to these claims often narrowly focuses on the magnitude of the costs or whether the regulatory action will create jobs and in so doing ignores several serious ethical problems with these arguments.

In policy disputes about matters in which potential harms are acknowledged by opponents of proposed policies, the public debate about the acceptability of the harms is often limited to some form of “cost-benefit analysis”(CBA).

Yet CBAs frequently hide important ethical issues. If, for instance, a CBA concludes that government action to protect vulnerable people or ecological systems should not be taken because costs of taking action to reduce an environmental threat outweigh the economic value of harms avoided by the proposed regulation, controversial ethical assumptions may be hidden in factual assertions about the magnitude of the costs or value of benefits particularly if:

  • Potentially but not fully proven catastrophic harms were ignored in the CBA.
  • The costs of taking action would be imposed upon parties that are harming others, yet the victims of the harm have not consented to be harmed.
  • Things that were believed to be sacred by one culture are valued in the CBA as if they were commodities whose value can be measured adequately by “willingness-to-pay” monetary measures. CBAs usually commodify all human values and thus value is restricted to monetary value while ignoring other values including sacred value or beliefs that certain entities should not be for sale. Thus in CBAs, usually the value of things that could be harmed are measured by human preferences measured in monetary values. Yet ethics is concerned with what preferences people should hold, not simply what preferences people hold.
  • Human rights will be violated if regulatory action is not taken.
  • The proposed government action implements the ethical duty of people to not harm others on the basis of self-interest.
  • The CBA determined economic value of entities that might be harmed are determined without obtaining the consent of those who might be harmed.
  • The benefits of government action to protect the environment are discounted too greatly in calculations that seek to allow future benefits of action to be compared to current costs to those who must act to prevent harm (Brown, 2008).

Thus, if a decision to take no government action on a potential environmental problem is justified only as a matter of imbalance between costs and benefits, very dubious ethical assumptions are frequently hidden in the CBA calculations while ethical principles, including those that have been widely acknowledged as valid and applicable to government policy formation are often ignored.

In this writer’s experience, proponents of environmental policies also not only rarely identify the ethical problems with the use of CBAs or almost any cost-based argument made in opposition to proposed policies, they almost always respond to the cost-based arguments by making counter cost claims. And so public debate about proposed policies usually focuses on economic  “factual” claims while ignoring ethical principles.

Evidence of the utter dominance of instrumental rationality in the United State includes executive orders of several US presidents which require that any US proposed regulation must satisfy a CBA before it may be promulgated (Congressional Research Service, 2017).

This is so despite the fact that, as we have seen, a CBA used as a prescriptive guide to policymaking often hides many controversial ethical issues including, for instance, the duty of nations to not harm others on the basis of national economic self-interest.

Using cost to those causing harm to others as justification for failing to abate the harm also violates well-established principles of international environmental law including the “polluter pays principle” (Rio Declaration,1992, Principle 16 ) and the “no harm principle.” (UNFCCC,1992, Preamble)..

Yet the United States continues to very frequently base the acceptability of environmental regulations on the results of a CBA.

In 1997, while working as the Program Manager for United Nations Organizations in the US Environmental Protection Agency (EPA) Office of International Affairs, this author closely observed the US debate about whether the US should agree to the Kyoto Protocol under the UNFCCC. This debate focused exclusively on two different CBAs, one completed by the US EPA and the other by the US Department of Energy which reached slightly different conclusions about the magnitude of negative impacts on US GDP if the US agreed to be bound by the Protocol. Amazingly both CBAs examined costs and benefits to the United States alone if the United States ratified the Kyoto Protocol while completely ignoring potentially harsh climate impacts on poor people around the world and the most vulnerable nations. Yet no one in the US government nor NGOs participating in the debate about whether the US should ratify the Kyoto Protocol raised any ethical problems with the US reliance on CBAs that examined costs and benefits to the US alone as a tool to determine the appropriateness of US action on climate change.

In most Western capitalist countries, corporations and their industry associations have huge political power to frame public policy questions and don’t hesitate to exercise their power to prevent any government action that could lower corporate profits.  And so the public debate on proposed policies often focuses on economic “facts,” not ethical duties, despite the almost universally accepted ethical norm agreed to by almost all religions and nations that people should not harm others on the basis of self-interest.

Opposition arguments against proposed environmental policies often rest on the unstated very dubious norm that regulatory action limiting commercial activities should not be taken unless the harms are proven by the government with high degrees of scientific certainty even in cases where achieving high levels of certainty is scientifically difficult or very prohibitively expensive.

For over 30  years, opponents of US action on climate change have frequently based their opposition on scientific uncertainty about human-caused climate change harms despite the fact that the United States agreed to the “precautionary principle” when it agreed to the UNFCCC in 1992. (UNFCCC. 1992, Art 3.3) This principle says that governments will no longer fail to take action on the basis of scientific uncertainty. Yet advocates of national action on climate change in response to opponents’ scientific uncertainty arguments almost always simply claim that the scientific “facts” of harm have been sufficiently scientifically demonstrated not on the ethical rule that precaution is required once it is scientifically established that significant harm might be created by certain human activities.

If a government decides not to act to reduce the threat of environmental harm on the basis of lack of proof of harm, such a decision can hide important ethical questions particularly if:

  • The government assumes that the proponents of government action to prevent environmental harm should shoulder the burden of proof of demonstrating harm particularly in matters where proof is very expensive, difficult to demonstrate, or cannot be fully demonstrated before potential harms are experienced..
  • There is credible but uncertain evidence that the current activity may be approaching thresholds that could trigger very serious consequences.
  • If the government waits until all uncertainties are resolved it will be too late to prevent serious harm.
  • Some very serious potential harm is judged to be low probability just because the mechanism for causing serious harm is not completely understood so that the probability of the serious harm cannot be confidently evaluated.
  • The victims of potential harm have not consented to put at risk.

All of these considerations are relevant to climate change yet, the United States has failed to decisively act on climate change since international climate change negotiations began 30 years ago because opponents of US climate change policies have claimed that there is insufficient proof of human-induced climate change caused harms.

Although the most prestigious scientific institutions in the world including most national academies of science and the Intergovernmental Panel on Climate Change have concluded with high levels of confidence that humans are causing and threatening great harms from human-induced climate change, even conceding, for the sake of argument, that great harms from human induced climate change are not yet proven, ethical principles requires that action should be taken to reduce the threat of climate change. Yet the ethical basis for requiring action is almost never discussed in the US public debate about whether scientific uncertainty about human-induced climate change is an appropriate justification for US unwillingness to act on climate change.

Scientists employed by environmental agencies usually focus on understanding the environmental harms and risks of various human activities and whether proposed government action will acceptably reduce threats to human health and the environment. The goals of environmental regulatory action are usually given to them by law or regulation such as water pollution should be reduced to prevent unreasonable harm to humans or ecological systems. Yet, in the face of scientific uncertainty about whether human actions may cause harm, scientists cannot determine who should have the burden of proof or what quantity of proof should satisfy the burden of proof by scientific methods alone because these are fundamentally ethical questions.

An understanding the ethical problems with instrumental rationality leads to an understanding of why nations often ignore even well-established ethical principles in policy formation such as the ethical principle that no nation should harm others outside their jurisdiction on the basis of national economic interest.

For this reason, a first-order problem on the road to a world which formulates policies guided by ethical principles is to open policy formation controversies to express consideration of ethical issues. This goal requires that those engaged in policy formation spot and identify the ethical issues frequently hidden in economic and scientific arguments against proposed policies that currently dominate policy formation controversies on environmental issues around the world.

Unfortunately most professionals engaged in environmental policy formation have no training that would help them identify the hidden ethical issues embedded in arguments made against environmental and sustainable development policies. Nor do those NGOs who participate in  controversies about these issues have the training to spot ethical problems made by opponents of proposed policies that are derived from various forms of instrumental rationality.

The Moral Outrageousness of Trump’s Decision on the Paris Agreement

 

 

 

 

 

 

When Pope Francis in May of 2015 issued his Laudata Si encyclical which called climate change a moral issue, it got global attention. Yet despite extensive international media coverage of worldwide condemnation of President Trump’s decision to remove the United States from the Paris agreement, there has been relatively little coverage of why the Trump decision should be understood not only as a dangerous break with the international community but as a profoundly immoral choice.

Climate change has certain features that more than any other global environmental problem call for responding to it as a moral problem. First, it is a problem caused mostly by high-emitting developed countries that are putting relatively low emitting developing countries most at risk. Second, the potential harms to the most vulnerable nations and people are not mere inconveniences but include catastrophic threats to life and the ecological systems on which life depends. Third, those people and nations most at risk can do little to protect themselves by petitioning their governments to shield them; their best hope is that high-emitting nations will respond to their obligations to not harm others. Fourth CO2 emissions become well mixed in the atmosphere so that COatmosphere concentrations are roughly the same around the world regardless of the source of the emissions. Therefore unlike other air pollution problems which most threaten only those nations and communities located within the pollution plume, greenhouse gas emissions from any one country are threatening people and other countries around the world.  This means that US greenhouse gas emissions are causing and threatening enormous harm all over the world.

Under the 2015 Paris accord, 195 nations agreed to cooperate to limit warming to as close as possible to 1.5°C and no more than 2.0°C.  Even nations that have historically opposed strong international action on climate change, including most of the OPEC countries, agreed to this warming limit goal because there is a broad scientific consensus that warming above these amounts will not only cause harsh climate impacts to millions around the word, but could lead to abrupt climate change which could create great danger for much of the human race. The international community’s condemnation of the Trump decision is attributable to the understanding that achieving the Paris agreement’s warming limit goals will require the cooperation of all nations and particularly high emitting nations including the United States to adopt greenhouse gas reduction targets more ambitious than nations have committed to thus far. For this reason, most nations view the Trump decision as outrageously dangerous.

Trump justified his decision by his claim that removing the United States from the Paris agreement was consistent with his goal of adopting policies that put America first. According to Trump staying in the Paris Agreement would cost America as much as 2.7 million lost jobs by 2025 including 440,000 fewer manufacturing jobs. This claim was based on a dubious study by National Economic Research Associates which was funded by the U.S. Chamber of Commerce and the American Council for Capitol Formation.  This study has been widely criticized for several reasons including that it neither counted the number of jobs which would be created in the renewable energy industry in a transformed energy sector nor the economic benefits of preventing climate change caused harms.

Yet it is the Trump assertion that the United States can base its energy policy primarily on putting US economic interests first while ignoring US obligations to not harm others that most clearly provokes moral outrage around the world. The moral principle that people may not harm others on the basis of self-interest is recognized by the vast majority of the world’s religions and in international law under the “no harm principle”.  The “no- harm’ rule is a principle of customary international law whereby a nation is duty-bound to prevent, reduce, and control the risk of environmental harm to other nations caused by activities within the nation  For these reasons, the Trump decision on the Paris Agreement is a moral travesty.

Reflections on the Marrakech Climate Negotiations In Light of the American Election

marraketch-symbol

I arrived in Marrakech on Thursday am, November 10 just as the news of the election of Donald Trump was hitting the world like a large meteor hitting the Atlantic Ocean.

I had come to Marrakech to participate in international climate negotiations to which 193 countries had come in hope of making progress on finding a global solution to the increasingly frightening climate change emergency.  All 193 countries had agreed in Paris the year before to work together to try to limit warming to as close as possible to 1.5 degrees C but no more than 2 degrees C. The international community was convinced that their previous promise to work to limit warming to 2 degrees C was much too dangerous particularly for many desperately poor countries. Yet to achieve the new warming limits, nations will need to greatly strengthen their commitments made in Paris, a goal which was the organizing focus of the Marraketch meeting.

On the first day of the negotiations, I was listening to two women, one from the Maldives and the other from Bangladesh, describing the suffering their families and communities were already experiencing from floods and rising seas. They also pleaded for much more aggressive action from developed countries to reduce GHG emissions as  waves of grief, despair and sadness about the US election were reverberating through the huge Marrakech negotiating complex.

As I encountered colleagues from previous climate negotiations, every conversation began with sorrowful laments about the US election. Particularly those of us who were veterans of most of the 23 year climate negotiating history were painfully aware of the anomaly that the Obama administration represented compared to the administrations of prior US Presidents as a positive force in the international efforts to find a global solution to climate change’s enormous threats.  We therefore felt deep grief about the Trump election and his promise to rip up the Paris Agreement and reestablish coal as an energy source.

For most of the 23 year history of the climate negotiations, the United States, along with two or three other nations,  often played a blocking role in international efforts to find a global solution to climate change. In no small part because of the delay caused by US obstruction, the world is running out of time to prevent potentially very dangerous climate change despite the Obama’s administrations recent more positive commitments.

The climate change disinformation campaign funded by many fossil fuel companies and free market fundamentalist foundations that started in the United States in the late 1980s and moved to several other developed countries is in no small part responsible for the rise of atmospheric CO2 to 403 ppm from about 320 ppm, a level that existed when calls to control GHG emissions began in earnest in the 1970s.

Because the international community has not found a way yet to actually reduce global GHG emissions to safe levels, and some parts of the world are already experiencing life-threatening floods and droughts, killer heat waves and storm surges, and rises in tropical diseases, the success of US climate change opponents in blocking meaningful US climate change policies has created a monumental threat to the entire world. Now President-elect Trump is threatening to reinstate the United State as the chief obstructionist on climate change issues among nations.

Yet shortly before the Marrakech COP, optimism about chances for preventing catastrophic warming was rising as 55 countries representing 55% of global emissions ratified the Paris Agreement allowing the Paris deal to come into effect on October 4th of this year, more quickly than expected. At the beginning of the Marrakech negotiation session, it appeared to me that the Trump election had punctured the optimism filled balloon that was rising shortly before the Marrakech COP.

Compared to many of the first 21 international climate negotiating meetings, which are referred to as Conference of the Parties or COPs under the 1992 United Nations Convention on Climate Change (UNFCCC), the agenda and expectations for the Marrakech session (COP22) were modest despite a growing sense of urgency and alarm among climate scientists that time is running short to prevent extraordinarily  dangerous climate change.

The most important agenda items for Marrakech were filling in details of general decisions made in the Paris Agreement that must be clarified if the accord’s goal of limiting warming to as close as possible to  1.5 degrees C but no greater than 2 degrees C has any chance of being achieved.

And so much of the Marrakech negotiations were focused on such non-sexy issues as:

(a) how a global dialogue that the Paris Agreement calls for on assessing the state of affairs in 2018 will be organized,

(b) how to assure the clarity and sufficiency of information that nations must provide with their commitments under the Paris agreement prior to five-year “stocktakes” and to implement the Paris Agreement’s “transparency mechanism,”

 (c) how to make progress on the financing promises of developed countries for developing country programs on adaptation and mitigation,

(d) how to assure that the Paris Agreement’s market mechanisms which give governments flexibility in how they achieve GHG emissions reduction commitments don’t undermine the Agreement’s warming limit goal.

Although these issues are not as politically explosive as issues that were under consideration in the other 21 COPs, they are nonetheless crucial steps that must be taken to implement the Paris accord.

The fog of sadness triggered by the Trump election coupled with the lack of visible progress on increasing the ambition of national commitments so urgently needed to keep warming to non-dangerous levels initially created a dark mood in the negotiating complex. However, as the negotiations continued into the second week, at least this writer was buoyed by the determination, if not outright defiance, of people and countries from around the world that I kept experiencing during the last few days of the COP.

In addition to the negotiations, much of what goes on at a COP are in numerous side-events, where reports are heard from non-government organizations, national and international scientific institutions, research organizations, and businesses supporting technologies that have hope of contributing to the solution to climate change. Being at a COP is like having a two-week intensive course on all that is going on with climate change around the world.

marraketch-positive

At one of  the side events I attended, I began to notice the rise of a positive defiance that countries around the world were displaying about the future of the Paris Agreement despite the bad news from the United States. This positive mood was fueled in part by the numerous examples of rapid progress being made around the world in installing non-fossil energy. Also all countries acted at the COP as if they understood that climate change was a very serious global threat that urgently required the cooperation of all nations to prevent catastrophic harm to people and ecological systems on which life depends.

In one side event, the energy Secretary from Vermont reported that one in every twenty jobs in her state were in the solar industry and that solar energy is already transforming Vermont’s energy supply.

Johnathan Pershing, lead US negotiator, claimed that the US solar industry was employing over 2,500,000 people while only 86,000 were working in the coal industry.

One of the side events discussed growing cooperation on climate change between California and several Canadian Provinces along with growing regional cooperation around the world on climate issues

Many of the 193 countries participating in the Marrakech negotiations had displays which depicted not only significant amounts of installed renewable energy in their countries, but plans for greatly expanded use or climate friendly technologies including electric vehicles and green building in the years ahead.

There was considerable discussion in Marrakech about the rapidly expanding and ambitious role that cities around the world have committed to play to fight climate change. Recently 7,100 cities from 119 countries and six continents, representing more than 600 million inhabitants, over 8% of the world’s population have committed to cooperate together under the Global Covenant of Mayors for Climate & Energy. In addition 20 of the world’s largest cities have committed to achieve carbon neutrality or at minimum to reduce GHG emissions by 80% by 2050. The cities include: Adelaide, Australia, Berlin, Germany, Boston MA, Boulder CO, Copenhagen,Denmark, London, United Kingdom, Melbourne, Australia, Minneapolis MN, New York City NY, Oslo, Norway, Portland OR, Rio de Janeiro, Brazil, San Francisco CA, Seattle WA, Stockholm, Sweden, Sydney, Australia,Toronto, Canada, Vancouver, Canada, Washington, DC, and Yokohama, Japan.

Several times throughout the COP I heard participants proclaim defiantly that they were going to “Trump Proof” the world. They claimed they were going to go ahead with or without the United States.  Several claimed that if the United States pulled out of the Paris deal, they would pursue economic sanctions against the United States

The day before I left Marrakech, I felt a positive change in my mood. I had been affected by positive energy from thousands around the world attending the COP. They promised to strive to implement the Paris Agreement without the United States. However, only if the United States aggressively reduces its GHG emissions is there much hope of preventing climate change that will harm millions of the worlds poorest people because 20 % of global GHG emissions come from the United States..

The Marrakech COP produced a few very modest advancements in the Paris deal while deferring important decisions to the next COP which will be held in Bonn, Germany next year.

Urgent Call to Climate Journalists Around The World: Research Concludes You Are Tragically Failing to Cover Climate Change Issues Through An Ethical and Justice Lens

Slide1

Research conducted by Widener University Commonwealth Law School and the University of Auckland concludes that national debates about climate change policies and the press coverage of these issues are for the most part ignoring the obvious ethical and moral problems both with how nations are justifying climate change commitments and the arguments of climate change policy opponents at the national level. (See Nationalclimatejustice.org under “lessons learned.”) This is so despite the fact that:

(a)  It is impossible for a nation to think clearly about climate policy until the nation takes a position on two ethical issues: (1) what warming limit the nation is seeking to achieve through its policy, and (d) what is the nation’s fair share of safe global emissions. These are ethical issues that can’t be decided through economic or scientific analysis alone.

(b) Climate change policy making raises numerous ethical issues that arise in policy formulation. (See below)

(c) Ethical arguments made in response to the arguments of climate change policy arguments are often the strongest arguments that can be made in response to the claims of climate  policy opponents because most arguments made by opponents of climate policies fail  to pass minimum ethical scrutiny.

(d) Climate change more than any other environmental problem has features that scream for attention to see it fundamentally as a moral, ethical, and justice issue. These features include: (a) It is a problem overwhelmingly caused by high-emitting nations and individuals that is putting poor people and nations who have done little to cause the problem at greatest risk, (b) the harms to the victims are potentially catastrophic losses of life or the destruction of ecosystems on which life depends, (c) those most at risk usually can’t petition their own governments for protection, their best hope is that high emitters of ghgs will respond to their moral obligations to not harm others, and, (d) any solution to the enormous threat of climate change requires high emitting nations to lower their ghg emissions to their fair share of safe global emissions, a classic problem of distributive justice.

Our research has discovered that most journalists and national debates about climate policies around the world  have largely ignored the numerous ethical issues that arise in climate policy formation and instead usually have narrowly responded to the arguments of the opponents of climate policy which have almost always been variations of claims that climate change policies should be opposed because: (a) they will harm national economic interests, or (b) there is too much scientific uncertainty to warrant action.

Yet numerous issues arise in climate change policy formation for which ethical and moral considerations are indispensable to resolve these issues and moral arguments about these issues are by far the strongest responses to arguments on these issues usually made by opponents of climate policies. The issues include:

  • Can a nation justify its unwillingness to adopt climate change policies primarily on the basis of national economic interest alone?
  • When is scientific uncertainty an ethically acceptable excuse for non-action for a potentially catastrophic problem like climate change given that waiting until the uncertainties are resolved makes the problem worse and more difficult to solve?

Why ethics requires that Intended Nationally Determined Contributions (INDCs) identify: (1) tonnes of CO2eq emissions reduced rather than a percent reduction from a baseline year, (b) the temperature limit and associated carbon budget that the INDC is seeking to achieve, (c) the equity principles that the nation relied on to assure the justice of its INDC, and (d) For Annex 1 countries, ghg emissions in 1990, the common baseline year.

INDC implications aubrey

COP-21 INDCs Compared With Carbon Budgets to achieve a warming limit of: (a)  3 to 4 degrees C, (b) a 50% probability of 2 degrees C, (c) a 66% probability of 2 degrees C , and, (d)  1.5 degrees C.  Global Commons Institute, Aubrey Meyer.

I. Introduction.

The above chart by the Global Commons Institute compares INDCs filed by nations with the UNFCCC before Paris with the reductions that would be needed by the entire world to live within carbon budgets that may not be exceeded if warming will be limited to;  between 3 degrees and 4 degrees C, a 50% chance of limiting warming to 2 degrees C, a 66% chance of limiting warming to 2 degrees C, and a reasonable chance of limiting warming to 1.5 degrees C.

A quick glance at the chart makes it clear that the INDCs that have been submitted by nations so far makes it very unlikely that the international community will be successful in limiting warming to 2 degrees C and virtually impossible to limit warming to 1.5 degrees C unless nations make significant increases in the ambition of their INDCs.

This entry argues that because nations have clear ethical duties to make national commitments on ghg emissions reductions consistent with their fair share of safe global emissions, they have duties to provide clear and transparent information about how their INDCs satisfies the nation’s ethical duty to limit its ghg emissions to levels which are sufficiently ambitious and fair so that citizens around the world can evaluate whether a nation has satisfied its ethical obligations. Furthermore, because national INDCs that have been submitted to the UNFCCC do not contain crucial information that is necessary to evaluate the nation’s compliance with its ethical obligations, nations must submit additional information to allow citizens around the world to  evaluate national compliance with its ethical obligations to prevent dangerous climate change.

All developed countries and some non-Annex 1 countries have submitted INDCs that have made commitments on the basis of percent reductions below a baseline year such as 1990 or 2005 by a specific date such as 2030, 2050, etc.

Although nations were encouraged by the Lima COP-20  decision in 2014  to include in their INDC submissions information that was transparent as to  why their INDC was sufficiently ambitious and fair, few nations have done this.

As of October 8th, 2015, 121 INDC submissions have been filed with the UNFCCC, reflecting 148 countries (including the European Union member states), and covering around 86% of global emissions in 2010 (excluding land use and forest emissions) and 87% of global population.) Most nations have not submitted information that is useful in determining the adequacy of the ambition or fairness of the INDCs submitted.

II. Why nations have a strong ethical duty to be clearly transparent on how they satisfied their ethical obligations to reduce its ghg emissions to the nation’s fair share of safe global emissions. 

A strong ethical case can be made that if nations have duties to limit their ghg emissions to their fair share of safe global emissions, a conclusion that follows both as a matter of ethics and justice and several international legal principles including, among others, the “no harm principle,” and promises nations made in the 1992 UNFCCC to adopt policies and measures required to prevent dangerous anthropocentric interference with the climate system in accordance with equity and common but differentiated responsibilities, nations have a duty to clearly explain how their national ghg emissions reductions commitments arguably satisfy their ethical obligations to limit their ghg emissions to the nation’s fair share of safe global emissions.

Because information submitted by nations with their INDCs does not contain sufficient information to help evaluate the ethical acceptability of national INDCs, nations should submit additional information needed to evaluate a nation’s compliance with its ethical obligations to prevent dangerous climate change.

The ethical duty to clearly explain how a nation satisfied its ethical obligations for climate change follows from the ethical duty of nations to not harm others beyond their national boundary. Although nations could reasonably disagree on what equity frameworks should guide national commitments on ghg emissions, no nation can deny its responsibility to reduce its ghg emissions on the basis of equity and principles of distributive justice to levels that will prevent dangerous climate impacts around the world. Unless nations specifically identify the equity principles that have guided their ghg emissions reductions, and the assumptions about warming limits entailed by their INDC,  nations and citizens around the world who may be harmed by illigitmate uses of common pool resources have an insufficient factual basis to challenge the potentially unethical responses of nations to their ethical obligations.  From this it is clear that nations have a strong duty to be clear on how they satisfied their ethical responsibilities for climate change. Yet almost all INDCs submitted thus far have either no information or inadequate information on how the nation satisfied its ethical duties in regard to the sufficient ambition or the justice of its INDC.

III. The ethical basis for why national INDCs should specify; (a) the number of tons of ghg emissions that will be reduced by implementation of the INDC by a specific date, (b) the warming limit and associated carbon budget that the nation’s INDC is seeking to achieve in cooperation with other nations, (c) the equity principles assumed by the nation in determining the fairness of its INDC, and (d) for Annex 1 nations,  emissions reductions that will be achieved by the INDC from 1990, a common baseline year. 

Any national ghg emissions reduction commitment is implicitly a position on two ethical questions, namely, first, what safe atmospheric ghg concentration level the commitment is designed to achieve and, second, what equity framework or principles of distributive justice the INDC is based on. Although some nations have acknowledged their ethical duties to base their INDC on ethically justifiable criteria, almost all INDC submissions have not explained how specific emissions reductions commitments link to a specific desired atmospheric ghg concentration levels and its associated carbon budget that will provide some level of confidence that a warming limit will be achieved nor why their ghg emissions reductions commitment is fair as a matter of distributive justice.

In fact no nation has explained quantitatively how its commitment is related to an atmospheric carbon budget or a specific equity framework. In addition the information submitted with INDCs submitted so far make it virtually impossible to rigorously evaluate the adequacy of the INDC as a matter of ethics and justice.

Almost all INDCs that have been submitted thus far by developed nations commit to a percentage reduction in ghg emissions from a baseline year by a a stated year. Although some nations acknowledge that their climate policies should be guided by ethical principles, no nation has expressly explained quantitatively how their commitments were specifically guided by ethical principles.

Because the acceptability of an INDC is a matter of ethics and justice, and citizens need additional information about the INDC to be able to evaluate the ethical acceptability of the INDC, INDCs submitted should be supplemented by additional information because an INDC expressed as a percent reduction from a given baseline year by a certain future date does not reveal:

(a) the percentage of the global carbon budget that will be consumed by the nation’s emissions because a percentage reduction commitment does not say when the reductions will be achieved yet the speed with which the reductions are achieved will affect the tonnes of any remaining carbon budget with quicker reductions consuming less amounts of the available carbon budget while waiting until the end of the period to achieve the percent reduction committed to will consume much more of the remaining carbon budget;

 

(b) the carbon budget in gigatons of CO2eq that the INDC is seeking to achieve. Because different carbon budgets will provide different levels of confidence that warming will be limited to specific temperature increases and the amount of temperature increase that an INDC has implicitly deemed to be acceptable to the nation is an ethical issue at its core, the nation should be required to link the INDC to a specific carbon budget so that the ambition of the INDC can be evaluated through an ethical lens.

 

(c) the equity framework or principles assumed by the nation in determining how much of a global carbon budget should be allocated to the nation in establishing its INDC such as contraction and  convergence, ghg development rights, historical emissions responsibilities, or other principles of distributive justice.  Although reasonable people may disagree what equity framework is just, nations should be expected to expressly specify the equity framework or principles of  distributive justice they used in determining their INDC so that citizens around the world can evaluate claims about fairness made by a nation in setting its INDC.

 

(d) the fairness of the baseline year selected such as 1990. Some nations including the United States have selected baseline years such as 2005 which represents the year of its peak emissions, 13 years after the United States agreed in the 1992 UNFCCC to adopt policies and measures to prevent dangerous climate change that would return ghg emissions to levels that existed before 1992 by 2000. Although the international community could reasonably adopt different baseline years, ideally the baseline year should be consistent among nations so that citizens could more easily compare commitments and understand how a nation has taken responsibility for policies they adopted or failed to adopt after the nation agreed to adopt climate policies and measure in the 1992 UNFCCC. Although a strong case can be made that historical ghg emissions before 1990 should be considered in determining a nation’s fair share of safe global emissions, selecting a common baseline year such as 1990 would facilitate easier citizen comparison of national commitments while retaining the rights of nations to make arguments that historical ghg emissions should be considered in any equity framework.

For these reasons, ghg emissions reductions commitments in INDCs should be: (a) stated in tons of ghg emissions reductions rather then percent reductions  from a baseline year, (b) identify the temperature limit and its associated carbon budget that the INDC is seeking to achieve to satisfy its ethical responsibilities to prevent dangerous climate change, (c) identify the equity framework or principles a nation followed to assure that its ghg emissions reductions were fair and just, and (d) compute its ghg emissions reductions commitment from the baseline year of 1990.

Obama Implicitly Acknowledges the Enormous Damage Caused By the Fossil Fuel Corporate Funded Climate Change Disinformation Campaign and Its Political Mercenaries

obama alaska

During his speech on August 31 in Alaska, President Obama not only spoke about the enormity of the climate change threat and the urgency of strong action, he also acknowledged that the United States has responsibility for causing the problem. He said:

I’ve come here today, as the leader of the world’s largest economy and its second largest emitter, to say that the United States recognizes our role in creating this problem, and we embrace our responsibility to help solve it. 

He spoke in clear terms about the enormity of the climate change threat:.

Our understanding of climate change advances each day.  Human activity is disrupting the climate, in many ways faster than we previously thought.  The science is stark.  It is sharpening.  It proves that this once-distant threat is now very much in the present. But the point is that climate change is no longer some far-off problem.  It is happening here.  It is happening now.  Climate change is already disrupting our agriculture and ecosystems, our water and food supplies, our energy, our infrastructure, human health, human safety — now.  Today.  And climate change is a trend that affects all trends — economic trends, security trends.  Everything will be impacted.  And it becomes more dramatic with each passing year. 

But if those trend lines continue the way they are, there’s not going to be a nation on this Earth that’s not impacted negatively.  People will suffer.  Economies will suffer.  Entire nations will find themselves under severe, severe problems.  More drought; more floods; rising sea levels; greater migration; more refugees; more scarcity; more conflict.

If we were to abandon our course of action, if we stop trying to build a clean-energy economy and reduce carbon pollution, if we do nothing to keep the glaciers from melting faster, and oceans from rising faster, and forests from burning faster, and storms from growing stronger, we will condemn our children to a planet beyond their capacity to repair:  Submerged countries.  Abandoned cities.  Fields no longer growing.  Indigenous peoples who can’t carry out traditions that stretch back millennia.  Entire industries of people who can’t practice their livelihoods.  Desperate refugees seeking the sanctuary of nations not their own.  Political disruptions that could trigger multiple conflicts around the globe.

President Obama also acknowledged that because nations have delayed in taking meaningful climate action, the world is running out of time to prevent catastrophic warming. More specifically he said:

On this issue, of all issues, there is such a thing as being too late. That moment is almost upon us.

And so President Obama admitted that: (a) climate change is a civilization challenging problem with dire potential consequences for nations and vulnerable people around the world, (b) the world is running out of time to prevent catastrophic warming, and, (c) the United States has responsibility for causing the problem.

The United States is not only responsible for the current crisis because, as President Obama noted, it is the second highest emitter of ghg in the world behind China,  it has historically emitted much more ghgs into the atmosphere than any other country including China, it is currently near the top of all nations in per capita ghg emissions, and the US has been responsible more than any other developed nation for the failure of the international community to adopt meaningful ghg emissions reduction targets from the beginning of international climate negotiations in 1990 until the Obama administration. (For a detailed description of the blocking role that the United States has played in international climate negotiations since 1990 until the Obama administration, See Brown, 2002, American Heat; Ethical Problems the US Response to Global Warming, and Brown, 2013,  Climate Chang Ethics: Navigating the Perfect Moral Storm)

In the Alaska speech, President Obama did not discuss the forces in the United States that have successfully undermined proposals for serious US climate change policies, matters which have been extensively discussed here under the category of “climate change disinformation campaign.”  Since the mid-1980s a well-funded  climate change disinformation campaign has successfully fought against US climate change policies. (For a discussion of the climate change disinformation campaign see, for example: The Climate Change Disinformation Campaign: What Kind Of Crime Against Humanity, Tort, Human Rights Violation, Malfeasance, Transgression, Villainy, Or Wrongdoing Is It? Part One: Is The Disinformation Campaign a Crime Against Humanity or A Civil Tort? ) This campaign has largely been funded by fossil fuel companies and free-market fundamentalists foundations although recently it has been difficult to track the funding. (See, New Study Concludes That Tracking Funding Of The Ethically Abhorrent Climate Disinformation Campaign Is Now Impossible)

As we have documented in numerous articles on the disinformation campaign on this website, although responsible scientific skepticism is necessary for science to advance, the climate change disinformation campaign has been involved not in the pursuit of responsible scientific skepticism but in tactics that are morally reprehensible including: (a) telling lies about mainstream climate scientific evidence or engaging in reckless disregard for the truth, (b) focusing on unknowns about climate science while ignoring settled climate change science, that is cherry-picking the evidence, (c) creating front groups and Astroturf groups that hide the real parties in interest behind claims, (d) making specious claims about “good science”, (e) manufacturing science sounding claims about climate change by holding conferences in which claims are made and documents are released that have not been subjected to scientific peer-review, and (d) cyber bullying journalists and scientists. These tactics are not responsible scientific skepticism but disinformation.

In the late 1980s, the European Union proposed that all developed countries should accept binding ghg emissions reductions targets. These targets would have likely been agreed to in the United Nations Framework Convention on Climate Change if the United States did not oppose them. The  United States virtually standing alone prevented the inclusion of binding targets in the treaty which was finalized in 1992 and ratified by the US in that same year. During the next 20 years, the US continued to block a meaningful global solution to climate change while being one of only a handful of nations that did not ratify the Kyoto Protocol, a treaty in which most developed countries accepted a ghg reduction target.

During this time, the climate change disinformation campaign also successfully prevented enactment of meaningful US domestic climate change laws and policies.

For the last several decades, US media has largely failed to cover the fact that the longer the world waits to make significant reductions in ghgs, the more difficult the problem becomes to solve. In this regard, the staggering enormity of the current challenge to the world to prevent dangerous climate change is rarely commented on in the US media despite the fact the 25 year delay in facing this problem has now made the  problem a civilization challenging problem.  For instance, James Hansen in a recent affidavit submitted in a legal proceeding against the State of Oregon asserted that the world must now reduce ghg emissions at a rate of 6% per year to avoid dangerous climate change. Yet as Hansen notes, if the world began to phase out of fossil fuel in 2005 the rate of reductions needed would only be 3.5% while waiting until 2020 will require a 15% reduction per year. Thus the delay in confronting climate change that is attributable to a large extent to the climate change disinformation campaign and its political mercenaries has made the problem much more difficult to solve with the result that harsh climate change impacts are much more likely. Because the harshest impacts from climate change will likely be experienced by some of  the world’s poorest people in Africa,Southeast Asia, and other parts of the world, the damage caused by the climate change disinformation campaign may become a global catastrophe.

And so the world is now facing a civilization challenging problem entailed by the need to rapidly reduce greenhouse gases to avoid catastrophic climate change.

Although President Obama has announced administrative measures that would begin to reduce US ghg emissions, these measures are now being intensely fought by the climate change disinformation campaign and its political representatives and the Obama commitments still don’t represent the US fair share of safe global ghg emissions. In fact, in his August 31 speech, President Obama said after describing his climate initiatives: “But we’re not moving fast enough.”   And now it may be too late to prevent huge climate change induced harms because the world has lost 25 years in reducing the threat of climate change in no small measure due to the United States opposition to a meaningful global solution.

President Obama’s August 31 speech in Alaska implicitly acknowledged this conclusion. Yet the US media largely continues to fail to cover the enormous damage that has been caused by the delay in confronting human-induced warming  .

Questions That Should Be Asked of Opponents of Climate Change Policies, Including Politicians, To Help Expose the Ethical, Moral, and Justice Problems with Their Positions

Bathtub revised

I. Introduction

If climate change, as the Pope’s recent encyclical claims, is a profound global justice, ethical, and moral problem, this paper identifies questions that should be asked of opponents of climate change policies to expose the ethical problems with their positions.

Although the Pope bases his claim that climate change is a moral problem on theological arguments derived mostly from Catholic teachings, this paper begins with a brief description of unique features of climate change that lead to an understanding that this enormous global threat must be understood fundamentally and essentially as a moral, ethical, and justice problem as a matter of secular ethics also. This is followed by questions designed to assure that opponents of climate change policies are required to expressly respond to ethical problems with their most frequent arguments made against climate change policies. These questions are organized according to the most frequent arguments made against climate change policies which are claims that climate change policies: (a) will impose unacceptable costs on a national economy or specific industries or prevent nations from pursuing other national priorities, (b) should not be adopted because of scientific uncertainty about climate change impacts, or (c) are both unfair and ineffective as long as high emitting nations such as China or India do not adopt meaningful ghg emissions reduction policies. Following each question is a short explanation of the strong ethical arguments for rejecting the arguments of the climate change policy opponents that have triggered the specific questions.

II. Why Climate Change Must be Understood as an Ethical, Moral, and Justice Problem.

Climate change must be understood and responded to as a profound problem of global justice, ethics, and morality. This is so because in addition to the theological reasons given by Pope Francis recently: (a) it is a problem mostly caused by some nations and people emitting high-levels of greenhouse gases (ghg) in one part of the world who are harming or threatening tens of millions of living people and countless numbers of future generations throughout the world who include some of the world’s poorest people who have done little to cause the problem, (b) the harms to many of the world’s most vulnerable victims of climate change are potentially catastrophic, (c) many people most at risk from climate change often can’t protect themselves by petitioning their governments; their best hope is that those causing the problem will see that justice requires them to greatly lower their ghg emissions, (d) to protect the world’s most vulnerable people nations must limit their ghg emissions to levels that constitute their fair share of safe global emissions, and, (e) climate change is preventing some people from enjoying the most basic human rights including rights to life and security among others. Because climate change is a profound problem of ethics, morality and justice those causing the problem may not use self-interest alone as justification for their policy responses to human-induced warming, they must respond in ways consistent with their responsibilities and duties to others. In light of this the following questions should be asked of those who oppose national action on climate change on the basis of excessive cost to national economies, scientific uncertainty, or unfairness if other high emitting nations refuse to reduce their ghg emissions. .

III.  Questions That Should Be Asked of Those Opposing Climate Change to Expose the Ethical and Moral Problems with Their Opposition.  

A. Questions to be asked of those opposing government action on climate change on the basis of cost to the economy, cost to specific industries, job destruction, or other economic arguments that oppose adoption of climate change policies.

When you argue that governments should not adopt policies to reduce ghg emissions to their fair share of safe global emissions on the basis that climate policies will impose unacceptable costs on national economies, destroy specific industries, kill jobs, or prevent the nation from investing in other national priorities:

1. Do you deny high-emitting nations not only have economic interests but also duties and obligations to nations and people most vulnerable to climate impacts to limit their ghg emissions to their fair share of safe global emissions?

This question is designed to expose a strong ethical and moral problem with those who refuse to reduce their ghg emissions on the basis of costs to them, a position that ignores that those harming others have strong ethical, moral, and legal responsibilities to not harm others. This strong ethical and moral responsibility is derivable both from the universally accepted moral principles including the widely accepted golden rule which requires people to treat others as they wish to be treated, and international law including, but not limited to the “no harm” rule  which is a widely recognized principle of customary international law whereby a State is duty-bound to prevent, reduce and control the risk of environmental harm to other states and a rule agreed to by all nations in the preamble to the UNFCCC, the “polluter-pays principle” agreed to by almost all nations in the 1992 Rio Declaration, human rights law which requires nations to assure that their citizens enjoy human rights, and many other legal theories including tort law. 

2.  Do you agree that no nation has a right to kill other people or destroy the ecological systems on which life depends simply because reducing ghg emissions will impose costs on the high-emitting nation?

Like question one, this question is designed to expose more explicitly than previous questions that those nations who refuse to limit ghg emissions to their fair share of safe global emissions are implicitly ignoring their very strong ethical duty to not kill or greatly harm others.

3. Do you deny that all high ghg emitting developed nations under the UNFCCC has a duty to adopt policies that prevent harms from climate change to  human health and ecological systems on which life depends which the nation is causing in other nations?

In addition to the ethical problems with cost arguments identified above in response to questions one and two, this question is also designed to expose that a nation that refuses to reduce its ghg emissions to its fair share of safe global emissions is violating promises it made under the UNFCCC to adopt ” policies and measures to prevent dangerous anthropocentric interference with the climate system.” and that the developed nations have promised to take the lead in reducing ghg emissions.

4. Do you deny the applicability of the well-established international norm that polluters should pay for the harms caused by their pollution and that if a nation or entity refuses to reduce its ghg emissions it is responsible for any damages or harms caused by their ghg emissions?

This question is designed to more expressly expose the ethical issue identified in response to question one, namely that high-emitting nations are responsible for the harms they are causing to others under the “polluter pays” principle of international law. This rule is also a basis for concluding that high-emitting nations have a duty to pay for the damages caused by ghg emissions from their country that exceed their fair share of global emissions.

5. Do you agree that a nation that refuses to reduce its ghg emission to its fair share of safe global ghg emissions on the basis of cost to it is implicitly taking  a position on how high atmospheric concentrations of ghgs should be allowed to rise and that the higher atmosphere ghg concentrations rise the more people and the ecological systems on which life depends will be harmed?.

This question is designed to expose that refusals of nations to reduce their emissions to their fair share of safe global emissions is implicitly a position on acceptable levels of atmospheric ghg concentrations which is essentially a moral issue because a position on acceptable atmospheric ghg concentrations is a position of a nation on who it is willing to kill or greatly harm by their ghg emissions. 

6. Do you agree that a national ghg emissions target that is based on cost to it must be understood as implicitly a position on a global emissions reduction pathway necessary to stabilize atmospheric ghg concentrations at safe levels and that the longer a nation waits to reduce its ghg emissions to its fair share of safe global emissions the smaller is  the remaining carbon budget for the entire world that may not be exceeded to prevent dangerous climate change?

This question is designed to expose the fact that because delays in ghg emissions based on costs to the polluter makes the enormous threat of  climate change much more difficult to solve and more likely that serious harms and damages will be experienced, therefore arguments for delays in reducing ghg emissions based upon cost raise moral and ethical issues because the delays are making the problem worse. 

7. Do you agree that nations which emit ghgs at levels beyond their fair share of safe global emissions have a duty to help pay for reasonable adaptation needs and unavoidable damages of low-emitting vulnerable countries and individuals who have done little to cause climate change?

This question is designed to expose the fact that a nation’s  refusal to lower its  ghg emissions to its fair share of safe global emissions on the basis of costs creates financial obligations to pay for resulting harms and damages.

8. Do you agree that all the costs of inaction on climate change must be considered by nations who refuse to reduce their ghg emissions to their fair share of safe global emissions on the basis of cost to them?

This question is designed to expose that fact that a nation which refuses to reduce its ghg emissions on the basis of costs to it have a strong duty to expressly consider all the costs of damages created by inaction.  

9. Given that the United States and most other developed anions have  for over twenty-five years failed to adequately respond to climate change because of alleged unacceptable costs to each nation and that due to the delay ghg emissions reductions now needed to avoid potentially catastrophic climate change are much steeper and costly than what would be required if these nations acted twenty five years ago, is it just for the United States and other developed nations  to now defend further inaction on climate change on the basis of cost to it?

This question is designed to expose the fact that previous unwillingness to reduce ghg emissions by a nation has caused dangerous delays which should be understood to create moral obligations to delay no longer in reducing ghg emissions to the nation’s fair share of safe global emissions. 

10. Do you believe that a nation who desires to delay to reduce its ghg emissions on the basis of costs to it, should have a responsibility to consult with those who will be harmed by the delay before delay is initiated?

This question is designed to expose the fact that procedural justice requires that that those who seek to put others at greater risk on the basis of cost has a duty as a matter of procedural justice to seek consensus from those who may be harmed by non-action. 

B. Questions to be Asked of Those Opposing Action on Climate Change on the Basis of Scientific Uncertainty.

When you argue that nations such as the United States or states, regional, or local governments, businesses, organizations, or individuals that emit high levels of greenhouse gases (ghg) need not reduce their ghg emissions to their fair share of safe global emissions because of scientific uncertainty about adverse climate change impacts:

1. On what specific basis do you disregard the conclusions of the United States Academy of Sciences, and numerous other Academies of Sciences Around the World including the Royal Academy of the UK,  over a hundred of the most prestigious scientific organizations whose membership includes those with expertise relevant to the science of climate change, including the American Association for the Advancement of Science, the American Geophysical Union, the American Institute of Physics, the American Meteorological Society, the Royal Meteorological Society,  and according to the American Academy of Sciences 97 percent of scientists who actually do peer-reviewed research on climate change which conclusions hold that the Earth is warming, that the warming is mostly human caused, and that harsh impacts from warming are already being experienced in parts of the world, and that the international community is running out of time to prevent catastrophic warming.

This question is designed to expose the ethical conclusion that nations who are put on notice by the most prestigious and responsible scientific organizations  in the world that ghg emissions from their jurisdictions are causing great harm to vulnerable people around the world have an ethical duty to accept the burden of proof to prove that their ghg emissions are not causing harm. That is once there is a reasonable scientific basis for concluding that some nations or entities are causing great harm, the question of who should have the burden of proof is an ethical and not simply a scientific question.  Thus the question is designed to bring attention to the ethical duty of those who are engaged in risky behavior to produce credible scientific evidence that demonstrates that their behavior is not causing harm if they choose to use uncertainty as justification for continuing the risky behavior.   That risky behavior is not acceptable because there is some uncertainty about the harm that will be caused by the behavior is clear from law around the world that makes dangerous behavior unacceptable and often criminal. For instance, it is not a defense to reckless driving that the police could not prove the driving would cause harm. Nations and people have a moral duty to  stop engaging in behaviors that might be causing harm once they are put on notice that their behavior is dangerous.  

2. Assuming, for the sake of argument, that there are some remaining scientific uncertainties about climate change impacts, are you arguing that no action of climate change should be taken until all scientific uncertainties are resolved given that waiting to resolve uncertainties before action is taken will virtually guarantee that it will too late to prevent catastrophic human-induced climate change harms to people and ecological systems around the world?

This question is designed to bring attention to the ethical duty to take action in the face of uncertainty if waiting until the uncertainties are resolved will produce greater harm if the harms are caused particularly for problems like climate change that the predicted harms are likely catastrophic to some people and regions.. 

3. Given that waiting until uncertainties are resolved will make climate change harms worse and the scale of reductions needed to prevent dangerous climate change much more daunting, do you deny that those who are most vulnerable to climate change’s harshest potential impacts have a right to participate in any decision about whether a nation should wait to act to reduce the threat of climate change because of scientific uncertainty?

This question is designed to expose the ethical duty entailed by procedural justice to obtain consensus from those who will be harmed by any delay in taking action on the basis of uncertainty when delay will likely increase the harms to those most vulnerable to the dangerous behavior. 

4. Should a developed nation such as  the United States which has much higher historical and per capita emissions than other nations be able to justify its refusal to reduce its ghg emissions to its fair share of safe global emissions on the basis of scientific uncertainty, given that if the mainstream science is correct, the world is rapidly running out of time to prevent warming above 2 degrees C, a temperature limit which if exceeded may cause rapid, non-linear climate change.

This question, following up on question one is designed to expose the ethical duty of high-emitting developed countries like the United States to refrain from further delay on climate change on the basis of scientific uncertainty given that the nation’s  non-action on climate change is  already responsible for putting the international community in great danger from climate change. 

5. If you claim that there is no evidence of human causation of climate change are you aware that there are multiple “fingerprint” studies and “attribution” studies which point to human causation of observed warming?

This question. following up on question one, is designed to expose the fact that there is a strong ethical duty to assume human causation of climate change if there is reliable evidence of human causation and that those who seek to justify non-action on climate change because they claim that human causation has not been proven have a very strong ethical duty to demonstrate that humans are not causing climate change with high levels of proof. More specifically in regard to the question of human causation, opponents of climate change policies that deny human causation should be expected to specifically respond to the numerous “foot-print” and “attribution” studies that the international community has relied on to make conclusions about human causation.

6. When you claim that the United States or other nations emitting high levels of ghgs need not adopt climate change policies because adverse climate change impacts have not yet been proven, are you claiming that climate change skeptics have proven in peer reviewed scientific literature that human-induced climate change will not create harsh adverse impacts to the human health and the ecological systems of others on which their life often depends and if so what is that proof?

This question is designed to expose that those who seek to rely on scientific uncertainty as justification for non-action on climate change have a strong ethical duty to produce very credible scientific evidence that supports the conclusion that human activities releasing ghgs are not causing climate change and its impacts. 

7. If you concede that climate skeptics have not proven in peer-reviewed journals that human-induced warming is not a very serious threat to human health and ecological systems, given that human-induced warming could create catastrophic warming the longer the human community waits to respond to reduce the threat of climate change and the more difficult it will be to prevent dangerous warming, do you agree that those responsible for rising atmospheric ghg concentrations have a duty to demonstrate that their ghg emissions are safe?

This question is designed to provoke express ethical reflection on the fact that those most responsible for dangerous atmospheric concentrations of ghg have a strong ethical duty to demonstrate that additional levels of ghg in the atmosphere are safe. 

8. Given that in ratifying the United Nations Framework Convention on Climate Change (UNFCCC) the United States in 1992 agreed under Article 3 of that treaty to not use scientific uncertainty as an excuse for postponing climate change policies, do you believe the United States is now free to ignore this promise by refusing to take action on climate change on the basis of scientific uncertainty? Article 3 states:

The Parties should take precautionary measures to anticipate, prevent or minimize the causes of climate change and mitigate its adverse effects. Where there are threats of serious or irreversible damage, lack of full scientific certainty should not be used as a reason for postponing such measures, taking into account that policies and measures to deal with climate change should be cost-effective so as to ensure global benefits at the lowest possible cost. (UNFCCC, Art 3)

This question is designed to bring attention to the fact that because all nations that ratified the UNFCCC agreed to not use scientific uncertainty as an excuse for not reducing their ghg emissions, they have an ethical duty to keep their promises.

9. If a nation such as the United States which emits high-levels of ghgs refuses to reduce its emissions to its fair share of safe global emissions on the basis that there is too much scientific uncertainty to warrant action, if it turns out that human-induced climate change actually seriously harms the health of tens of millions of vulnerable people around the world and ecological systems on which their life depends, should the nation be financially responsible for the harms that could have been avoided if preventative action had been taken earlier?

This question is designed to bring attention to the ethical duty of nations to pay for damages that result from their delays in taking action on the basis of scientific uncertainty. 

10. Do you agree that if a government is warned by some of the most prestigious scientific institutions in the world that activities within its jurisdiction are causing great harm to and gravely threatening hundreds of millions of people outside their government’s jurisdiction, government officials who could take steps to assure that activities of their citizens do not harm or threaten others should not be able escape responsibility for preventing harm caused by simply declaring that they are not scientists?

This question is designed to expose that those politicians who refuse to reduce their government’s ghg on the basis that they are not scientists cannot ethically justify non-action on climate change on this basis because once they are put on notice by respected scientific organizations that ghg from their government jurisdiction are harming others, they have a duty to prevent dangerous behavior or establish credible scientific evidence that the alleged dangerous behavior is safe. 

C. Questions to be asked of those opposing government action climate change on the basis that other nations such as China and India have not reduced their ghg emissions.

When you argue that nations such as the United States need not reduce its ghg emissions to its fair share of safe global emission because other nations such as China have not taken action,

1. Are you claiming that no nation has a duty to reduce its ghgs emissions to its fair share of safe global emissions until all other nations reduce their greenhouse gas emissions accordingly?

This question is designed to expose the ethical duty of all nations to reduce their ghg emissions to their fair share of safe global emissions regardless of what other nations do because any nation emitting ghg emissions above its fair share of safe global emissions is contributing to elevated atmospheric ghg concentrations which are harming and threatening others. 

2. If you claim that the US or other developed nation  has no duty to act on climate change until China acts, do you agree that economic competitors such has China have no duty to reduce their emissions until the United States does so?

This question is designed to bring attention to the fact if the United States or other high-emitting nation has no duty to reduce its ghg emissions to its fair share of safe global emissions until other nations do the same, no nation has a duty to act until the US responds to its obligations, a patently absurd conclusion. 

3. Are you aware that the claim frequently made by opponents of US  and other national action on climate change that if the country acts to reduce its ghg emissions and China or other developing country dose not act it will make no difference because climate change will still happen is not true because ghg emissions from nations exceeding their fair share of safe global emissions are responsible for rising atmospheric concentrations of ghgs?

This question is designed to correct the false claim that as long as a country such as China does not act, any action by a high-emitting nation such as the  United States to reduce its ghg emissions makes no difference. This is factually not true because as long as a developed nation’s ghg emissions are above its fair share of safe global emissions they are contributing to rising atmospheric concentrations of ghgs. 

4. Are you aware that the United States agreed when it ratified the United Nations Framework Convention on Climate Change in 1992 to adopt policies and measures to prevent dangerous anthropogenic interference with the climate system on the basis of equity and common but differentiated responsibilities and that developed nations agreed to take the lead in reducing the threat of climate change?

This question is designed to bring attention to the fact that the United States and other developed nations have promised to take action to reduce their ghg emissions to their fair share of safe global emissions regardless of what other nations do under the UNFCCC.

6. Are you aware that all nations have a duty under customary international law to prevent harm by ensuring that activities within their jurisdiction or control do not cause damage to the environment of other States or of areas beyond the limits of national jurisdiction?

This question is designed to expose the ethical duty of the United States and other high-emitting nations under international law to prevent its citizens from engaging in activities which cause climate change damages as a matter international law without regard to what other nations do.

7. Are you aware that the United States is much more responsible for elevated atmospheric ghg concentrations than any other country including China because of US historical and per capita emissions?

This question is designed to expose the strong ethical obligation of the United States and many other high-emitting nations to reduce their ghg emissions without regard to what other nations do because they are  more responsible for dangerous elevated atmospheric levels of ghgs than any countries.
