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)

If we agree with the notion of a global community, then we must extend our concepts of justice, fairness, and equity beyond national borders by supporting measures to decrease global warming and to increase foreign aid, argues Peter Singer.

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 prospect of dangerous climate change requires Humanity to limit the emission of greenhouse gases. This in turn raises the question of how the permission to emit greenhouse gases should be distributed and among whom. In this article the author criticises three principles of distributive justice that have often been advanced in this context. He also argues that the predominantly statist way in which the question is framed occludes some morally relevant considerations. The latter part of the article turns from (...) critique and advances a new way of addressing the problem. In particular, first, it proposes four key theses that should guide our normative analysis; and, second, it outlines how these four theses can be realised in practice. (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.

Treaty Norms and Climate Change MitigationDarrel MoellendorfCurrently the international community is discussing the regulatory framework to replace the Kyoto Protocol after 2012. The unveiling of the new framework is scheduled to occur at the December 2009 COP in Copenhagen. The stakes are high, since any treaty will affect the development prospects of per capita poor countries and will determine the climate change–related costs borne by poor people for centuries to come. Failure to arrive at an agreement would have grave effects (...) on the development prospects of poor countries, many of which will experience the most severe effects of climate change. The original UNFCCC treaty recognizes these kinds of concerns and requires that further treaty negotiation pay them heed. Any agreement will be required to conform to UNFCCC norms related to sustainable development and the equitable distribution of responsibilities. In this paper I argue that UNFCCC norms tightly constrain the range of acceptable agreements for the distribution of burdens to mitigate climate change. I conclude that any legitimate treaty must put much heavier mitigation burdens on industrialized developed countries. Of the various proposals that have received international attention, two in particular stand out as possibly satisfying UNFCCC norms regarding the distribution of responsibilities. (shrink)

A currently popular proposal for fairly distributing emission quotas is the equal shares view, which holds that that emission quotas should be distributed to all human beings globally on an equal per capita basis. In this paper I aim to show that a number of arguments in favour of equal shares are based on a misleading analysis of climate change as a global commons problem. I argue that a correct understanding of the way in which climate change results from the (...) overuse of a global commons shows those who defend equal shares using commons arguments to be harbouring more controversial commitments than might at first appear. I then discuss two options for equal shares theorists who wish to maintain the view in the face of my critique, and attempt to show that one approach holds more promise than the other. (shrink)

What does it matter if the climate changes? This kind of question does not admit of a scientific answer. Natural science can tell us what some of its biophysical effects are likely to be; social scientists can estimate what consequences such effects could have for human lives and livelihoods. But how should we respond? The question is, at root, about how we think we should live—and different people have myriad different ideas about this. The distinctive task of ethics is to (...) bring some clarity and order to these ideas. (shrink)

Climate change and many environmental problems are caused by the accumulated effects of repeated actions by multiple individuals. Instead of relying on collective responsibility, I argue for a non-atomistic individual responsibility towards such environmental problems, encompassing omissions, ways of life, and consequences mediated by other agents. I suggest that the degree of causal responsibility of the agent must be balanced with the degree of capacity-responsibility determined by the availability of doable alternatives. Then, the more an agent has powers as a (...) group member, the more she is responsible to design the social structure and the infrastructures of the group towards sustainability. Finally, one can hold another agent responsible only if the accused is not in a vulnerable position and if she is capable to take reparative and adaptive actions. (shrink)
