This is the second in a three part series examining the ethical and justice issues discussed by the IPCC Working Group III in its 5th Assessment Report (AR5) . In the first entry in  this series we concluded that although the recent IPCC AR 5 Working Group III report is laudable improvement over prior IPCC reports in regard to identifying ethical and equity issues that should be considered in developing climate change policy, some criticisms are also warranted of how IPCC has articulated the significance and implications of the ethical, justice, and equity principles that should guide nations in developing climate change policies.

In short, we will argue improvement is possible in how IPCC deals with ethics, justice, and equity issues entailed by climate change policy-making despite very significant improvements on these matters in the AR5 report compared to prior IPCC reports.

In this entry we will examine several preliminary ethical and justice issues raised by the new IPCC Working Group III Chapter 3, on Social, Economic, and Ethical Concepts.  The last entry will continue the examination Chapter 3 and then turn to Chapter 4 on Sustainable Development and Equity.

As a preliminary matter, one of the challenges that IPCC faces in its mandate on of ethics and justice issues relevant to climate change policy-making is that it is not IPCC’s role to be prescriptive in deciding what governments should do. It’s mandate is to synthesize the extant social-economic and scientific literature for policy-makers. In this regard, the IPCC chapter on ethics said expressly:

This chapter does not attempt to answer ethical questions, but rather provides policymakers with the tools (concepts, principles, arguments, and methods) to make decisions. (IPCC, 2014.WG III, Ch. 3, pg. 10)

And so it is not IPCC’s role to do ethical analyses of policy issues that raise ethical questions. IPCC can, however, distinguish between prescriptive and descriptive questions that arise in relevant socio-economic literature about climate policy-making, identify important ethical and justice issues that arise in this literature, where there is a consensus on ethics and justice issues in the relevant literature describe the consensus position, where there is no consensus on ethical and justice issues describe the range of reasonable views on these issues, and identify hard and soft law legal principles relevant to how governments should resolve ethical and justice issues that must be faced by policy-makers.

There are several subjects in climate change policy-making which raise important ethical and justice issues. They include policy judgements about:

  1. how much warming will be tolerated, a matter which is implicit but rarely identified when nations make ghg emissions reduction commitments,
  2. any nation’s fair share of safe global emissions, matters which are referred to by the IPCC usually as burden-sharing or effort-sharing considerations and a matter taken up in chapter 4 of IPCC, Working Group III chapter on sustainability and equity,
  3. any nation’s responsibility for funding reasonable adaptation and compensation for losses and damages for those who are harmed by climate change,
  4. when a nation is responsible for its ghg emissions given differences in historical and per capita emissions among nations,
  5. responsibility for funding technology transfer to poor nations,
  6. how to evaluate the effects on and responsibilities to others of climate change technologies that are adopted in response to the threat of climate change, including such technologies as geo-engineering or nuclear power, for instance,
  7. who has a right to participate in climate change policy-making, a topic usually referred to under the topic of procedural justice,
  8. the policy implications of human rights violations caused by climate change,
  9. the responsibility of not only nations but subnational governments, entities, organizations, and individuals for climate change,
  10. when economic analyses of climate change policy options can prescribe or limit national duties or obligations to respond to the threat of climate change,
  11. ethical and justice implications of decisions must be made in the face of scientific uncertainty,
  12. whether action or non-action of other nations is relevant to any nation’s responsibility for climate change,
  13. how to spend limited funds on climate change adaptation,
  14. when politicians may rely on their own uninformed opinion about climate change science,
  15. who is responsible for climate refugees and what their responsibilities are.

nw book advOn some of these issues, the recent IPCC report included a good summary of the extant ethical literature, on other issues important gaps in IPCC’s analysis can be identified, and lastly on a few of these issues, IPCC Working Group III is silent. IPCC reports cannot be expected to be exhaustive on these matters and therefore gaps and omissions in the IPCC reports in regard to ethics and justice issues relevant to policy-making is not necessarily a criticism of IPCC and is here pointed out only for future consideration. In fact, IPCC’s work on the ethical limits of economic arguments is a particularly important contribution to the global climate change debate. What is worthy of criticism, however, is if IPCC’s conclusions on guidance for policy-makers is misleading on ethics and justice issues.

II. Ethical Issues Raised by Economic Arguments About Climate Policy

Perhaps the most important practical ethical and justice issues raised by Working Group III’s work on ethics is its conclusions on the ethical and justice limitations of economic analyses of climate change policy options. This topic is enormously practically important because nations and others who argue against proposed climate change policies usually rely on various economic arguments which often completely ignore the ethical and justice limitations of these arguments (In the case of the United States, see Brown, 2012.) Because most citizens and policy-makers have not been trained in spotting ethically dubious claims that are often hidden in what appear at first glance to be “value-neutral” economic arguments, IPCC’s acknowledgement of the ethical limitations of economic arguments is vitally important.  It is also practically important because the first four IPCC reports, although not completely ignoring all ethical and justice problems with economic arguments about climate change policies, failed to examine the vast majority of ethical problems with economic arguments against climate change policies while making economic analyses of climate change policies the primary focus of Working Group III’s work thereby  leaving the strong impression that economic analyses, including but not limited to cost-benefit analyses, is the preferred way to evaluate the sufficiency of proposed climate change policies.  On this matter, the AR5 report has made important clarifications.

The AR5 III report included a section on this very issue entitled: Economics, Rights, and Duties which we reproduce here it  its entirety because of its importance to this discussion,  followed by comments in bold italics:

Economics can measure and aggregate human wellbeing, but Sections 3.2, 3.3 and 3.4 explain that wellbeing may be only one of several criteria for choosing among alternative mitigation policies.

Other ethical considerations are not reflected in economic valuations, and those considerations may be extremely important for particular decisions that have to be made. For example, some have contended that countries that have emitted a great deal of GHG in the past owe restitution to countries that have been harmed by their emissions. If so, this is an important consideration in determining how much finance rich countries should provide to poorer countries to help with their mitigation efforts. It suggests that economics alone cannot be used to determine who should bear the burden of mitigation.

What ethical considerations can economics cover satisfactorily? Since the methods of economics are concerned with value, they do not take into account of justice and rights in general. However, distributive justice can be accommodated within economics, because it can be understood as a value: specifically the value of equality. The theory of fairness within economics (Fleurbaey, 2008) is an account of distributive justice. It assumes that the level of distributive justice within a society is a function of the wellbeings of individuals, which means it can be reflected in the aggregation of wellbeing. In particular, it may be measured by the degree of inequality in wellbeing, using one of the standard measures of inequality such as the Gini coefficient (Gini, 1912), as discussed in the previous section. The Atkinson measure of inequality (Atkinson, 1970) is based on an additively separable social welfare function (SWF), and is therefore particularly appropriate for representing the prioritarian theory described in Section 3.4.6 . Furthermore, distributive justice can be reflected in weights incorporated into economic evaluations as Section 3.6 explains.

Simply identifying the level of inequality using the Gini Index does not assure that the harms and benefits of climate change policies will be distributed justly. For that a theory of just distribution is needed. The Gini index is also at such a level of abstraction that it is very difficult to use it as a way of thinking about the justice obligations to those most vulnerable to climate change. Even if there is strong economic equality in a nation measured by the Gini index, one cannot conclude that climate change policies are distributively just.

Economics is not well suited to taking into account many other aspects of justice, including compensatory justice. For example, a CBA might not show the drowning of a Pacific island as a big loss, since the island has few inhabitants and relatively little economic activity. It might conclude that more good would be done in total by allowing the island to drown: the cost of the radical action that would be required to save the island by mitigating climate change globally would be much greater than the benefit of saving the island. This might be the correct conclusion in terms of overall aggregation of costs and benefits. But the island’s inhabitants might have a right not to have their homes and livelihoods destroyed as a result of the GHG emissions of richer nations far away. If that is so, their right may override the conclusions of CBA. It may give those nations who emit GHG a duty to protect the people who suffer from it, or at least to make restitution to them for any harms they suffer.

Even in areas where the methods of economics can be applied in principle, they cannot be accepted without question (Jamieson, 1992; Sagoff, 2008). Particular simplifying assumptions are always required, as shown throughout this chapter. These assumptions are not always accurate or appropriate, and decision‐makers need to keep in mind the resulting limitations of the economic analyses. For example, climate change will shorten many people’s lives. This harm may in principle be included within a CBA, but it remains highly contentious how that should be done. Another problem is that, because economics can provide concrete, quantitative estimates of some but not all values, less quantifiable considerations may receive less attention than they deserve.

This discussion does not adequately capture serious ethical problems with translating all values into monetary units measured by willingness to pay or its surrogates nor that such transformation may greatly distort ethical obligations to do no harm into changes in commodity value.

The extraordinary scope and scale of climate change raises particular difficulties for economic methods (Stern, forthcoming). First, many of the common methods of valuation in economics are best designed for marginal changes, whereas some of the impacts of climate change and efforts at mitigation are not marginal (Howarth and Norgaard, 1992). Second, the very long time scale of climate change makes the discount rate crucial at the same time as it makes it highly controversial (see Section 3.6.2 ). Third, the scope of the problem means it encompasses the world’s extremes of wealth and poverty, so questions of distribution become especially important and especially difficult. Fourth, measuring non‐market values—such as the existence of species, natural environments, or traditional ways of life of local societies—is fraught with difficulty. Fifth, the uncertainty that surrounds climate change is very great. It includes the likelihood of irreversible changes to societies and to nature, and even a small chance of catastrophe. This degree of uncertainty sets special problems for economics. (Nelson, 2013) (IPCC, 2014.WG III, Ch. 3, pg. 12-13)

Again this discussion does not adequately describe the ethical problems with economic determinations of all values. In fact it leaves the impression that if non-market values can be discovered the problems of transforming all values to commodity values are adequately dealt with.

Chapter 3, also includes additional statements about the ethical limits of economic reasoning sprinkled throughout the chapter. They include:

1. Most normative analyses of solutions to the climate problem implicitly involve contestable ethical assumptions.(IPCC, 2014. WG III, Ch. 3, pg.10)

2. However, the methods of economics are limited in what they can do. They can be based on ethical principles, as Section 3.6 explains. But they cannot take account of every ethical principle. They are suited to measuring and aggregating the wellbeing of humans, but not to taking account of justice and rights (with the exception of distributive justice − see below), or other values apart from human wellbeing. (IPCC, 2014.WG III, Ch. 3, pg. 24)

And so Chapter 3 of the IPCC report contains a number or clear assertions  about the ethical limitations of economic arguments. However there are important gaps missing from this analysis. Also several sections of Chapter 3 that can be interpreted as claims that policy makers are free to choose economic reasoning as justification for climate policies. That is, some of the text reads as if a policy-maker is free to choose whether to base policy  on economic or ethical and justice considerations, choosing between these two ways of evaluation is simply an option. Some of these provisions follow with responses in italics

Chapter 3 page 6 says:

Many different analytic methods are available for evaluating policies. Methods may be quantitative (for example, cost‐benefit analysis, integrated assessment modeling, and multi‐criteria analysis) or qualitative (for example, sociological and participatory approaches). However, no single best method can provide a comprehensive analysis of policies. A mix of methods is often needed to understand the broad effects, attributes, trade‐offs, and complexities of policy choices; moreover, policies often address multiple objectives  (IPCC, 2014.WG III, Ch. 3, pg. 6)

Although economic analyses can provide policy-makers with valuable information such as which technologies will achieve ethically determined goals at lowest cost, thereby providing criteria for making remedies cost-effective, there are serious ethical problems with cost-benefit analyses used prescriptively to set emissions reductions targets. Some of these are alluded to in IPCC Chapters 3 and 4, others are not acknowledged. Because of the prevalence of cost-benefit justifications for climate change policies, future IPCC reports could make a contribution by identifying all of the ethical issues raised by cost-benefit analyses.

 Any decision about climate change is likely to promote some values and damage others. These may  be values of very different sorts. In decision making, different values must therefore be put together or balanced against each other. (IPCC, 2014. WG III, Ch. 3, pg. 6)

This provision can be understood as condoning a consequentialist approach to climate policy that fails to acknowledge deontological limits. Since when any nation makes policy on climate change it affects poor people and vulnerable nations around the world, there are serious procedural justice issues which go unacknowledged in this section and,  for the most part, all throughout Chapter 3. Nowhere does the chapter acknowledge that when a climate policy is  under development at the national level,  nations have no right to compare costs to them of implementing policies  with the harms to others that have not consented to the method of valuation being used to determine quantitative value.

Ideally, emissions should be reduced in each place to just the extent that makes the marginal cost of further reductions the same everywhere. One way of achieving this result is to have a carbon price that is uniform across the world; or it might be approximated by a mix of policy instruments (see Section 3.8 ). (IPCC, 2014.WG III, Ch. 3, pg. 26)

This statement fails to acknowledge that emissions reductions amounts should be different in different places according to well accepted principles of distributive justice. Although other sections of the chapter acknowledge that responsibility for climate change is a matter of distributive justice, this section and others leave the impression that climate policy can be based upon economic efficiency grounds alone. The way to cure this problem is to continue to reference other sections that recognize ethical limits in setting policy on the basis of efficiency.

(IPCC, 2014.WG III, Ch. 3, pg. 6)

Since, for efficiency, mitigation should take place where it is cheapest, emissions of GHG should be reduced in many developing countries, as well as in rich ones. However, it does not follow that mitigation must be paid for by those developing countries; rich countries may pay for mitigation that takes place in poor countries. Financial flows between countries make it possible to separate the question of where mitigation should take place from the question of who should pay for it. Because mitigating climate change demands very large‐scale action, if put in place these transfers might become a significant factor in the international distribution of wealth. Provided appropriate financial transfers are made, the question of where mitigation should take place is largely a matter for the  economic theory of efficiency, tempered by ethical considerations. But the distribution of wealth is amatter of justice among countries, and a major issue in the politics of climate change (Stanton, 2011). It is partly a matter of distributive justice, which economics can take into account, but compensatory justice may also be involved, which is an issue for ethics. (Section 3.3).(IPCC, 2014.WG III, Ch. 3, pg. 26)

There are a host of  potential ethical problems with mitigation taking place in one part of the world to satisfy the ethical obligations of a nation in another part of the world which is emitting above its fair share of safe global emissions that are not mentioned in this article. Included in these problems are:

  • Environmental Sufficiency. There are many technical challenges in assuring that a project in one part of the world that seeks to reduce ghg by an amount that otherwise would be required of a polluter will actually succeed in achieving the reductions particularly when the method of reduction is reliant on biological removal of carbon.
  • Permanence. Many proposed projects for reducing carbon in one part of the world to offset reductions ethically required in another part of the world raise serious questions about whether the carbon reduced by the project will stay out of the atmosphere forever, a requirement that is required to achieve the environmental equivalence to ghg emissions reductions that would be achieved at the source.
  • Leakage. Many proposed projects used to offset emissions reductions of high-emitters 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 offset is resumed at another location.
  • Additionality. A project that is proposed in another part of the world to offset emissions reductions of a high-emitting entity may not be environmentally effective if the project would have happened anyway for other reasons.
  • Allowing Delay In Investing In New Technology. The ability to rely on a cheaper emissions reductions project in another part of the world as a substitute of reducing emissions creates an excuse for high-emitting entities to delay investment in technologies that will reduce the pollution load. This may create a practical problem when emissions reductions obligations are tightened in the future. 

Chapter 3 also treats other important ethical issues that arise in climate change policy formation. They include:

3.3 Justice, equity and responsibility,

3.3.1 Causal and moral responsibility

3.3.2 Intergenerational justice and rights of future people

3.3.3 Intergenerational justice: distributive justice

3.3.4 Historical responsibility and distributive justice

3.3.5 Intra‐generational justice: compensatory justice and historical responsibility

3.3.6 Legal concepts of historical responsibility

3.3.7 Geoengineering, ethics, and justice

3.4 Values and wellbeing

3.4.1 Non‐human values

3.4.2 Cultural and social values

3.4.3 Wellbeing

3.4.4 Aggregation of wellbeing

3.4.5 Lifetime wellbeing

3.4.6 Social welfare functions

3.4.7 Valuing population

III. Some Additional Gaps In Chapter 3

Some of the gaps in Chapter 3 on ethical issues raised by climate change policy-making include: (1) ethics of decision-making in the face of scientific uncertainty, (2) whether action or non-action of other nations affects a nation’s responsibility for climate change, (3) how to spend limited funds on climate change adaptation, (4) when politicians may rely on their own uninformed opinion about climate change science, and (5) who is responsible to for climate refugees and what are their responsibilities.

The last entry in this series will continue the analyses of IPCC  Chapter 3 on Social, Economic, and Ethical Concepts and Chapter 4 on Sustainability and Equity.

ClimateEthics Analysis Moves to Widener University School of Law As EthicsandClimate.org

Dear former subscribers to ClimateEthics and new visitors  to Ethicsandclimate.org:

 

After over 80 articles on the ethics of climate change at ClimateEthics.org, I am moving to Widener University School of Law where the analyses formerly posted on ClimateEthics as well as new posts will continue at this site, EthicsandClimate.org. 

Climate change must be understood essentially as a civilization challenging ethical and moral problem. This realization has profound practical consequences for policy formation.   Yet the ethical implications of policy responses have usually been ignored in policy debates that have now spanned thirty years. Despite 20 years of international negotiations to come up with a global solution to climate change under the United Nations Framework Convention on Climate Change, the ethical and justice dimensions of national positions remain the key missing element in the positions of national governments.

This site examines the ethical dimensions of climate science, economics, politics, policy responses, trading, atmospheric greenhouse gas stabilization goals, as well as the obligations of nations, governments, businesses, organizations, and individuals to respond to climate change and pay for adaptation responses and damages.

The site will follow the positions taken by governments in international climate change negotiations and subject them to an ethical critique. The site will subject arguments made by proponents and opponents of  climate change policies to ethical scrutiny.

The site believes that turning up the volume on the ethical dimensions of climate change is key to moving the world to a just solution to climate change.

Because many of the most important ethical issues that need to be faced in climate change policy formation are often hidden in dense  scientific and economic discourses that most people, including many policy professionals, have difficulty in unpacking, this sites seeks to help those concerned about climate change understand the ethical issues often obscured by what first appears to be the “value-neutral” languages of science and economics.

For these reasons, the purpose of this site is to help civil society understand, debate, and respond to the ethical dimensions of climate change.

The Ethics of Carbon Cap and Trade Continued: Going Deeper On Our Original Analysis

I. Introduction.

This post continues exploration of ethical issues raised by the numerous carbon cap and trade regimes that have arisen or are under consideration around the world.

One of the happy surprises of publishing ClimateEthics is that occasionally we get comments on our entries that raise very important and thought-provoking questions about our initial ethical analysis. This is a response to helpful comments by Robert Sullivan on our recent entry on the Ethics of Carbon Trading. This post originally appeared at: http://rockblogs.psu.edu/climate/2010/06/ethical-issues-raised-by-carbon-cap-and-trade-regimes.html. The section numbers referenced below refer to sections in the original article. In that article, ClimateEthics examined ethical questions that arise in cap and trade programs. These ethical questions fell into the following categories: (a) Justice of the Cap, (b) Creating Property Rights in the Atmosphere, (c) Environmental Effectiveness, (d) Distributive Justice, and (e) Procedural Justice

In the last post, ClimateEthics explained that the purpose of the analysis was not to resolve all the many ethical issues raised by cap and trade but to encourage further exploration of these ethical issues. Thanks to the comments of Robert Sullivan, this post attempts to go deeper on some of the issues raised in the earlier post with the goal of continuing the exploration of the ethics of cap and trade regimes.

II. Specific Issues

1: Justice Of The Cap

In the original post, ClimateEthics argued that if the total society-wide cap, before it is allocated among emitters within the jurisdiction of the government allocating the cap, is less than the government’s fair share of safe global emissions, then the cap is not environmentally just particularly to those who are vulnerable to harsh climate change impacts. We also claimed that most existing cap and trade regimes could be accused of being insufficient as a matter of justice.

A. Comment -Mr. Sullivan says:

The first issue is justice of the cap. I agree with you that the world is not doing nearly enough to even put us on a pathway to avoiding catastrophic climate change let alone following that path. However, I don’t see a failure of caps being strict enough as an indication of the inherently unethical or unjust nature of cap and trade or emissions trading per se. Without having read any of the references you include on countries’ obligations, I am not sure I agree with the statement “many cap and trade regimes do not derive the quantity of the cap from these international obligations”. There is an international obligation under Article 2 of the UNFCCC to prevent “dangerous anthropogenic interference with the climate system”, and this is further articulated in the QELRCs set out in the Kyoto Protocol (see the first part of Art 2 of the UNFCCC which links into the KP, and also note the clarifying text at the end of Art 2 around also ensuring sustainable development). While I agree that the Kyoto caps are insufficient to meet Art 2 of the UNFCCC over the long term, the Kyoto caps do indeed reflect the most detailed set of international obligations with respect to GHG caps to date. I would argue these are the dominant obligations of countries under public international law, and the cap and trade system set up by the Kyoto Protocol complies with these obligations as does the European Emissions Trading Scheme. However, I also acknowledge that here you may be drawing a distinction between a countries legal obligations under public international law and some other sort of other (ethical?) obligations premised on cuts that are needed to avoid catastrophic climate change and some means of allocating these cuts amongst countries.

Whether or not a cap and trade represents a “fair share” is another issue. The caps are the result of political negotiations, and if there was no cap and trade there may still be emission reduction commitments and targets but I don’t think they would necessarily be any fairer simply because they were not linked to cap and trade. If anything developed countries would be less willing to assume steeper cuts, making cap and trade an ethical imperative as the most likely means of achieving the steepest global reductions.

B. Our Response

Mr. Sullivan probes appropriately about elements of our claim that if the cap is unjust the entire cap and trade regime may be unjust. It appears to us that there are several different questions Mr. Sullivan raises.

First, Mr. Sullivan asks what is the basis for our claim that many caps do not meet a nation’s fair share of safe global emissions.
Answer, there is a growing scientific consensus that to prevent dangerous climate change the world most likely needs to reduce global emissions by between 25 to 40 per cent by 2020.

A rich literature on this issue exists. In citing this literature it is important to acknowledge that because there is uncertainty about climate sensitivity, that is we don’t know for sure how much warming will be experienced at equilibrium from different concentrations of CO 2 equivalent in the atmosphere, various emissions reductions targets are recommended to give different levels of confidence that warming will be limited to additional warming targets such as 1.5 0C or 2 0C. We must also acknowledge that there is great controversy about whether 20C.should be the global warming limit target or 1.50C or even lower temperature should be the target. In addition, it should be recognized that there is no ethically neutral way of making this decision because of the inherent uncertainty in the climate sensitivity coupled with uncertainty about at what temperatures the Earth will experience rapid non-linear responses of the climate system. For this reason, determining a global target raises a host of ethical questions which are beyond the scope of this post. These ethical questions include who should have the burden of proof about what temperature levels are safe and what quantity of proof should satisfy the burden of proof. Nevertheless, there appears to be a growing scientific consensus that 20C should be, at the very minimum. a global warming temperature limit target that should be the goal of the UNFCCC.. However, as we will see, we don’t have to decide this to conclude that current caps are ethically problematic (see below). For a discussion of what reductions are needed to achieve a 20C, see.

See for example,

A. Emissions Cut Of 40% Below 1990 Levels By 2020 Needed For Industrial Countries For 2°C Limit, Potsdam Institute for Climate Research, http://www.pik-potsdam.de/news/press-releases/emissions-cut-of-40-below-1990-levels-by-2020-needed-for-industrial-countries-for-2b0c-limit

B. How To Avoid Dangerous Climate Change, Union of Concerned Scientists, http://www.ucsusa.org/assets/documents/global_warming/emissions-target-report.pdf

C. Climate targets ‘must be bolder’ a statement of one group of scientists on this issue: http://www.sciencealert.com.au/news/20091809-19778.html

However, given that global emissions most likely need to be reduced by at least 25% below 1990 levels by 2020 at the very minimum to give any reasonable confidence that the world will avoid rapid non-linear warming, one can conclude that national commitments made pursuant to the Copenhagen Accord will not achieve what is needed to achieve the 25% minimum reductions by 2020 because they just don’t add up to 25% reductions. A fortiori, individual high-emitting nations can be accused of not meeting their fair share of safe global emissions because fairness would require that high-emitting nations would have to achieve lower emissions than what is needed for the globe, yet no high emitting nations have made commitments at a levels which now appear to be necessary to achieve the 20C target for the entire world.

For this reason, a strong case can be made that existing caps on high-emitting countries do not achieve what justice would require of high-emitting nations to avoid dangerous climate change to others.
Second, Mr. Sullivan appropriately asks ClimateEthics whether given some of the caps that nations have agreed to are now legally recognized by international law such as the Kyoto Protocol, how can we say they are unethical.

We would argue that legal validity does not equal ethical sufficiency given that: (a) nations have never claimed that the emissions reductions commitments they have agreed to in accepting a cap represent their fair share of safe global emissions, (b) nations seem to base the legitimacy of their emissions reductions targets on national self-interest not international responsibility, and (c) nations have negotiated the cap that they have accepted on the basis of what was viewed by them to be politically viable. . We, therefore, don’t agree that legal commitments can be construed to satisfy ethical obligations.

One could of course argue, that making any legal commitments in a cap is better than no commitments. We would agree. However, ClimateEthics believes it is important to acknowledge that existing caps do not achieve what would be required of nations if they took their ethical responsibilities seriously to reduce their emissions to their fair share of safe global emissions.

Along this line, we believe it would be an improvement to require in international negotiations that each government be required to expressly articulate what atmospheric concentrations of ghg emissions their commitments are designed to achieve. No national target makes any sense unless it is seen implicitly as a position on a safe global atmospheric concentration target but nations are not asked to explain what global targets will be achieved by their voluntary targets and why their emissions commitments should be understood to constitute their fair share of total global emissions.

Third, we understand Mr. Sullivan to be asking once the cap is agreed in international negotiations, can we claim that the entire cap and trade regime is unjust.

We think this question raises interesting ethical issues not yet dealt with. Another way of stating this question is- if the world has agreed to caps in an international agreement, given the agreement how can we say the entire cap and trade regime is unjust. We believe the trade features of cap and trade could lead to seeing the entire scheme as unjust if the cap is unjust for the following reasons. If country A only agrees to a 10% reduction by 2020 when their fair share is 25% for instance, and they actually achieve 15% reduction they can sell the 5% excess tons to country B to be counted against country B’s target. This then creates two injustices. First country A has not achieved its fair target. Second it gets unjust revenues because the cap was set too low. This also gives the buying entity, country B a right to exceed its fair share of safe global emissions because it has bought credits from country A. From the standpoint of a country that is very vulnerable to climate change impacts, the trading scheme is unethical.

Ethical Issues Raised By Carbon Trading

I-Introduction

This post examines ethical issues raised by the cap and trade regimes that have emerged to solve the climate change crisis in the last decade. These regimes have emerged: (1) at the international level under the Kyoto Protocol, (2) at the regional international level including in the European Union and between US states and the Canadian provinces, and (3) at the sub-national level including among Northeastern U.S states. There is also a large voluntary carbon trading market that has emerged around the world that is not the focus of this post although these regimes raise many ethical issues considered here.

At the international level, under the Kyoto Protocol to the United Nations Framework Convention on Climate Change there are three different trading regimes. They are:

(a) Emissions Trading (ET) -A mechanism that allows a nation with a Kyoto target to buy d allowances from a country with a Kyoto target that does need all of its allowances.

(b) Joint Implementation (JI)-A mechanism that allows project financing by nation with a Kyoto target in another country with a Kyoto target.

(c) Clean Development Mechanism (CDM)-A mechanism that allows nations with Kyoto targets to finance projects in developing countries that reduce greenhouse gas emissions.

The goal of this post is to spot the major ethical issues raised by carbon cap and trade regimes that have emerged around world, not necessarily to resolve these issues.

Spotting ethical issues raised by cap and trade regimes will not necessarily lead to a consensus about what should be done about these issues because there are competing ethical theories that might reach different conclusions about these trading regimes including utilitarian, rights, virtue, relationship, and ecological based theories among others. However, for some issues there may be an overlapping consensus among ethical theories about what ethics requires. (Brown et al., 2006). For other issues there may be agreement among ethical theories that some positions on cap and trade issues are ethically problematic no matter what ethical theory is applied to analyze the issue under consideration. Therefore, spotting ethical issues raised by carbon cap and trade regimes may be practically valuable despite the inability on some issues to determine unambiguously what ethics demands, if spotting the ethical questions leads to eliminating from consideration some positions on these issues that fail to pass minimum ethical scrutiny. (Brown et al., 2006)

The purpose of this post is not to resolve all ethical issues entailed by cap and trade regimes but to encourage further ethical reflection about these issues. Cap and trade regimes have in a very short time reached wide support around the world with only very limited ethical reflection on the issues discussed in this chapter. Because uncritical acceptance of these existing regimes may lead to significant injustices and given that there may be opportunity to change and restructure existing regimes in the future, this post is meant to encourage ethical reflection on existing as well as future cap and trade regimes.

Although existing cap and trade regimes differ in many of their details, they all have the following common steps. First a government establishes an emission limitation for total emissions from the government’s jurisdiction and then permits or allowances are either given away or auctioned off and in this way create a society-wide “cap.” The cap is expected to be “tightened,” that is, reduced over the years, thus increasing the costs over time of future allowances. The permits allow holders to emit ghgs usually in tons of carbon for a specific period. To enable trading, rules are established that allow those entities with caps to meet their obligations either by purchasing unneeded allowances from others that have caps, funding projects that reduce emissions at places under the control of others, or purchasing off-sets created by carbon reduction projects somewhere in the world.

Cap and trade regimes are usually justified on several different grounds including:

• Trading provides a mechanism for making carbon emissions reductions at lowest possible cost. Because carbon is well mixed in the atmosphere, it doesn’t make any difference where reductions are made in the world to lower future atmospheric concentrations of ghgs. Therefore emitters of carbon can finance inexpensive projects to reduce carbon emissions and apply reductions achieved by these projects against their reduction obligations and in so doing reduce ghg emissions that cause climate change. In this way, cap and trade regimes maximize the efficiency of carbon reductions. And so cap and trade regimes are usually supported on the grounds that they provide the flexibility to achieve the greatest reductions at lowest possible cost.

• Proponents of cap and trade regimes often point to a successful program still in place in the US that has been declared to reduce 40% sulfur emissions (SOx) by coal-burning power plants in the period
1990-2004. (EDF, 2009)

• Cap and trade regimes provide economic benefits to developing countries through CDM credits and other “off-sets” thus helping developing countries economically.

• Cap and trade regimes keep high-cost emitters in the political game because they can reduce their emissions at low cost and thereby help minimize political opposition for climate change legislation.

This post next looks at the following ethical issues entailed by cap and trade regimes:

a. Justice of the Cap

b. Allocating Global Commons Resources as Property Rights.

c. Environmental Effectiveness

d. Distributive Justice

e. Procedural Justice
