This paper examines what would be a fair distribution of the right to emit greenhouse gases. It distinguishes between views that treat the distribution of this right on its own (Isolationist Views) and those that treat it in conjunction with the distribution of other goods (Integrationist Views). The most widely held view treats adopts an Isolationist approach and holds that emission rights should be distributed equally. This paper provides a critique of this 'equal per capita' view, and the isolationist assumptions (...) on which it depends. It examines four arguments for this view, finding each wanting. It then presents two general challenges to the 'equal per capita' view, and, indeed, any views which treat the distribution of greenhouse gas emissions in isolation from other goods. It concludes by outlining and defending an alternative (Integrationist) approach to the distribution of rights to emit greenhouse gases. (shrink)

This paper examines explore the issues of intergenerational equity raised by climate change. A number of different reasons have been suggested as to why current generations may legitimately favor devoting resources to contemporaries rather than to future generations. These - either individually or jointly - challenge the case for combating climate change. In this paper, I distinguish between three different kinds of reason for favoring contemporaries. I argue that none of these arguments is persuasive. My answer in each case appeals (...) to the concept of human rights. It maintains that a human rights-centered perspective to climate change enables us to address each of these reasons. (shrink)

Early discussions of ?climate justice? have been dominated by economists rather than political philosophers. More recently, analytical liberal political philosophers have joined the debate. However, the philosophical discussion of climate justice remains in its early stages. This paper considers one promising approach based on human rights, which has been advocated recently by several theorists, including Simon Caney, Henry Shue and Tim Hayward. A basic argument supporting the claim that anthropogenic climate change violates human rights is presented. Four objections to this (...) argument are examined: the ?future persons? objection; the ?risk? objection; the ?collective causation? objection; and the ?demandingness? objection. This critical examination leads to a more detailed specification and defence of the claim that anthropogenic climate change violates human rights. (shrink)

If dangerous climate change is to be avoided, it is vital that carbon sinks such as tropical rainforests are protected. But protecting them has costs. These include opportunity costs: the potential economic benefits which those who currently control rainforests have to give up when they are protected. But who should bear those costs? Should countries which happen to have rainforests within their territories sacrifice their own economic development, because of our broader global interests in protecting key carbon sinks? This essay (...) develops an argument from the “principle of fairness,” which seeks to establish that outsiders should pay states with rainforests so as to share the costs of protection. If they do not, they can be condemned for free-riding on forest states. The argument is, I suggest, compelling and also capable of enjoying support from adherents of a wide variety of positions on global justice. (shrink)

Climate change poses grave threats to many people, including the most vulnerable. This prompts the question of who should bear the burden of combating ?dangerous? climate change. Many appeal to the Polluter Pays Principle. I argue that it should play an important role in any adequate analysis of the responsibility to combat climate change, but suggest that it suffers from three limitations and that it needs to be revised. I then consider the Ability to Pay Principle and consider four objections (...) to this principle. I suggest that, when suitably modified, it can supplement the Polluter Pays Principle. (shrink)

The paper argues against the assumption that citizens of industrialized countries bear responsibility for greenhouse emissions in the nineteenth and early twentieth centuries. An array of arguments for such a historic responsibility is refuted. The crucial role of the assumption of a liability for bona fide misappropriation in a state of nature (Lockean strict liability) is pointed out.

In this paper, I explore the question of how the costs of undertaking an important type of climate change mitigation should be shared amongst states seeking an environmentally effective and equitable response to global climate change. While much of the normative literature on climate mitigation has focused on burden sharing within the context of reductions in emissions of greenhouse gas, I explore the question of how the costs of protecting tropical forests in order to harness their climate mitigation potential should (...) be distributed amongst developing and developed states. In response to this question, I outline and defend a ‘beneficiary pays’ account of forestry mitigation burden sharing that requires affluent states to finance measures supporting avoided deforestation while less affluent states, within whose territory these forests tend to be located, implement these measures. The normative basis for this account, I argue, is a principle of ‘unjust enrichment’ according to which developed states must bear much of the cost of avoided deforestation for its climate mitigation potential because of the huge economic benefits their citizens have accumulated from productive activities that have contributed to climate change.

Many suggest that we should look backward and measure the differences among various parties' past emissions of greenhouse gases to allocate moral responsibility to remedy climate change. Such backward-looking approaches face two key objections: that previous emitters were unaware of the consequences of their actions, and that the emitters who should be held responsible have disappeared. I assess several arguments that try to counter these objections: the argument from strict liability, arguments that the beneficiary of harmful or unjust emissions should (...) pay, and arguments from distributive justice. I argue that none of these successfully justify a backward-looking approach to the temporally remote portion of the climate burden. (shrink)

National greenhouse-gas accounting should reflect how countries’ policies and behaviours affect global emissions. Actions that contribute to reduced global emissions should be credited, and actions that increase them should be penalized. This is essential if accounting is to serve as accurate guidance for climate policy. Yet this principle is not satisfied by the two most common accounting methods. Production-based accounting used under the Kyoto Protocol does not account for carbon leakage — the phenomenon of countries reducing their domestic emissions by (...) shifting carbon-intensive production abroad1. Consumption-based accounting2,3 does not credit countries for cleaning up their export industries, and it also punishes some types of trade that could contribute to more carbon efficient production worldwide. We propose an improvement to consumption-based carbon accounting that takes technology differences in export sectors into account and thereby tends to more correctly reflect how national policy changes affect total global emissions. We also present empirical results showing how this new measure redraws the global emissions map. (shrink)

Should the current members of a community compensate the victims of their ancestor’s emissions of greenhouse gases? I argue that the previous generation of polluters may not have been morally responsible for the harms they caused.I also accept the view that the polluters’ descendants cannot be morally responsible for their ancestor’s harmful emissions. However, I show that, while granting this, a suitably defined notion of moral free-riding may still account for the moral obligation of the polluters’ descendants to compensate the (...) current victims of their ancestors’ actions. A concept of transgenerational free-riding is defined. Objections to the idea of using free-riding as part of a theory of justice are rejected. Two different views of moral free-riding are contrasted, with consequences for the amount of compensation to be exigible from the polluters’ descendants. Some final considerations are devoted to the possible relevance of this free-riding-based view for other issues of historical injustice. (shrink)

Very few moral philosophers have written on climate change.1 This is puzzling, for several reasons. First, many politicians and policy makers claim that climate change is not only the most serious environmental problem currently facing the world, but also one of the most important international problems per se.2 Second, many of those working in other disciplines describe climate change as fundamentally an ethical issue.3.

“[T]he Precautionary Principle still has neither a commonly accepted definition nor a set of criteria to guide its implementation. “There is”, Freestone … cogently observes, “a certain paradox in the widespread and rapid adoption of the Precautionary Principle”: While it is applauded as a “good thing”, no one is quite sure about what it really means or how it might be..

This paper examines the responsibilities of states to assist and to receive stateless people who are forced to leave their state territory due to rising seas and other unavoidable climate change impacts and the rights of ‘climate refugees’ to choose their host state. The paper employs a praxeological method of non-ideal theorising, which entails identifying and negotiating the unavoidable tensions and trade-offs associated with different framings of state responsibility in order to find a path forward that maximises the protection of (...) climate refugees within the constraints imposed by political feasibility. It argues that the responsibility of states to support climate refugees through financial and technical assistance should be treated separately from their responsibility to receive them. The former is a differentiated responsibility grounded in the ability to pay principle, or relative capability, while the latter is a common responsibility grounded in the fact that all states have causally contributed to their plight, albeit in varying degrees which cannot be, and need not be, precisely determined. A common state ‘responsibility to receive’ is linked with a right on the part of climate refugees to choose their host to suit their circumstances, which would provide a form of partial compensation for the injustice and trauma of their loss and damage. This right is expected to become more viable, and the political willingness of states to receive them more likely, the more that climate refugees are assured of adequate support for resettlement according to states’ differentiated responsibilities to assist.

Increasing global economic integration and recent military interventions in the name of human rights have forced questions of global justice into political discussions. Is the unequal distribution of wealth across the globe just? What's wrong with imperialism? Are the most indebted countries obligated to pay back their loans to international financ.

Esteemed philosopher John Broome avoids the familiar ideological stances on climate change policy and examines the issue through an invigorating new lens. As he considers the moral dimensions of climate change, he reasons clearly through what universal standards of goodness and justice require of us, both as citizens and as governments. His conclusions—some as demanding as they are logical—will challenge and enlighten. Eco-conscious readers may be surprised to hear they have a duty to offset all their carbon emissions, while policy (...) makers will grapple with Broome’s analysis of what if anything is owed to future generations. From the science of greenhouse gases to the intricate logic of cap and trade, Broome reveals how the principles that underlie everyday decision making also provide simple and effective ideas for confronting climate change. Climate Matters is an essential contribution to one of the paramount issues of our time. (shrink)

Climate change and justice are so closely associated that many people take it for granted that a global climate treaty should--indeed, must--directly address both issues together. But, in fact, this would be a serious mistake, one that, by dooming effective international limits on greenhouse gases, would actually make the world's poor and developing nations far worse off. This is the provocative and original argument of Climate Change Justice. Eric Posner and David Weisbach strongly favor both a climate change agreement and (...) efforts to improve economic justice. But they make a powerful case that the best--and possibly only--way to get an effective climate treaty is to exclude measures designed to redistribute wealth or address historical wrongs against underdeveloped countries. In clear language, Climate Change Justice proposes four basic principles for designing the only kind of climate treaty that will work--a forward-looking agreement that requires every country to make greenhouse--gas reductions but still makes every country better off in its own view. This kind of treaty has the best chance of actually controlling climate change and improving the welfare of people around the world. (shrink)

Climate change is a global problem that is predominantly an intergenerational conflict, and which takes place in a setting where our ethical impulses are weak. This "perfect moral storm" poses a profound challenge to humanity. This book explains how the "perfect storm" metaphor makes sense of our current malaise, and why a better ethics can help see our way out.

In a new preface, Peter Singer discusses the prospects for the ethical approach he advocates."--BOOK JACKET.

This commentary argues in defence of equal per capita emissions with historical accountability as a general rule for allocating the right to emit greenhouse gases. Historical accountability takes into account historical inequalities in per capita emissions. Implicitly it gives every human being an equal share of the global resource atmosphere, independent of place or time. Three reasons are put forward to argue why historical accountability should be the guiding principle for an international agreement allocating rights of emissions. In addition, as (...) it has been dismissed by many scholars, six arguments are given to refute objections against historical accountability. (shrink)

It is widely recognized that changes are occurring to the earth’s climate and, further, that these changes threaten important human interests. This raises the question of who should bear the burdens of addressing global climate change. This paper aims to provide an answer to this question. To do so it focuses on the principle that those who cause the problem are morally responsible for solving it (the ‘polluterpays’ principle). It argues thatwhilethishasconsiderable appeal it cannot provide a complete account of who (...) should bear the burdens of global climate change. It proposes three ways in which this principle needs to be supplemented, and compares the resulting moral theory with the principle of ‘common but differentiated responsibility’. (shrink)

Is drastic action against global warming essential to avoid impoverishing our descendants? Or does it mean robbing the poor to give to the rich? We do not yet know. Yet most of us can agree on the importance of minimising expected deprivation. Because of the vast number of future generations, if there is any significant risk of catastrophe, this implies drastic and expensive carbon abatement unless we discount the future. I argue that we should not discount. Instead, the rich countries (...) should stump up the funds to support abatement both for themselves and the poor states of the world. Yet to ask the present generation to assume all the costs of drastic mitigation.is unfair.Worse still, it is politically unrealistic.We can square the circle by shifting part of the burden to our descendants. Even if we divert investment from other parts of the economy or increase public debt, future people should be richer, so long as we avert catastrophe. If so, it is fair for them to assume much of the cost of abatement.What we must not do is to expose them to the threat of disaster by not doing enough. (shrink)

In order to decide whether a comprehensive treaty covering all greenhouse gases is the best next step after UNCED, one needs to distinguish among the four questions about the international justice of such international arrangements: (1) What is a fair allocation of the costs of preventing the global warming that is still avoidable?; (2) What is a fair allocation of the costs of coping with the social consequences of the global warming that will not in fact be avoided?; (3) What (...) background allocation of wealth would allow international bargaining (about issues like 1 and 2) to be a fair process?; and (4) What is a fair allocation of emissions of greenhouse gases (over the long-term and during the transition to the long-term allocation)? In answering each question we must specify from whom any transfers should come and to whom any transfers should go. As the grounds for the answers we usually face a choice between fault-based principles and no-fault principles. (shrink)

In recent years, climate policy under the United Nations system has been characterized by bottom-up, national approaches to climate mitigation. This raises concerns about the overall effectiveness of these mitigation policies, for example due to carbon leakage. In response to these concerns, authors have repeatedly suggested that policy makers consider a consumption-based climate policy approach. We analyze the potential merits of a switch to a consumption-based policy approach using the criteria of justice and economic efficiency. We argue that emissions must (...) be understood as being contributed by both, consumers and producers, but that this fact does not by itself settle the question whether consumption or production ought to serve as the climate policy base. Rather, the perspective of justice necessitates an analysis of the distributive consequences of switching from a production- to a consumption-based policy. -/- We find that both (global) cost-effectiveness and justice can be improved if the unilateral climate policies of industrialized countries are based on emissions from consumption. There are preconditions, however, the switch in the policy base must be accompanied by clean technology transfer, and if implemented by border carbon adjustments, import tax revenues need to be channeled to developing and emerging economies. We further show that in such a setting, export rebates are of minor importance for efficiency and justice. (shrink)
