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.

In recent years there has been a good deal of discussion of equality’s place in the best account of distribution or distributive justice. One central question has been whether egalitarianism should give way to a principle requiring us to give priority to the worse off. In this article, I shall begin by arguing that the grounding of equality is indeed insecure and that the priority principle appears to have certain advantages over egalitarianism. But I shall then claim that the priority (...) principle itself is ungrounded and that the priority principle should itself give way to a sufficiency principle based — indirectly, via the notion of an impartial spectator — on compassion for those who are badly off.

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)

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)

Utilitarians, maximinners, prioritarians, and sufficientarians each provide examples of situations demonstrating, often apparently compellingly, that a sensible ethical observer must adopt their view and reject the others. I argue, to the contrary, that an attractive ethic is eclectic or pluralistic, in the sense of coinciding with these apparently different views in different regions of the space of social states. I reject the view that an appealing ethic can be universally maximin, prioritarian, or utilitarian. Key Words: distributive justice • utilitarianism • (...) maximin • sufficiency • priority. (shrink)
