The emission of greenhouse gases causes climate change. Therefore, many support a global cap on emissions. How then should the emissions allowed under this cap be distributed? We first show that above average past emissions cannot be used to justify a right to above average current emissions. We then sketch three basic principles of distributive justice and argue, first, that prioritarian standards are the most plausible and, second, that they speak in favour of giving people of developing countries higher emission (...) rights than people of industrialised countries. In order to support this point it has to be shown, inter alia, in what ways the higher past emissions of industrialised countries are relevant for today’s distribution of emission rights. (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)

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)

I investigate whether any plausible moral arguments can be made for ‘grandfathering’ emission rights (that is, for setting emission targets for developed countries in line with their present or past emission levels) on the basis of a Lockean theory of property rights.

Climate change can be interpreted as a unique case of historical injustice involving issues of both intergenerational and global justice. We split the issue into two separate questions. First, how should emission rights be distributed? Second, who should come up for the costs of coping with climate change? We regard the first question as being an issue of pure distributive justice and argue on prioritarian grounds that the developing world should receive higher per capita emission rights than the developed world. (...) This is justified by the fact that the latter already owns a larger share of benefits associated with emission generating activities because of its past record of industrialisation. The second question appears to be an issue of compensatory justice. After defining what we mean by compensation, we show that different kinds of compensatory principles run into problems when used to justify payments by historical emitters of the North to people suffering from climate change in the South. As an alternative, we propose to view payments from wealthy countries for adaptation to climate change in vulnerable countries rather as a measure based on concerns of global distributive justice.

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)

Given that there is a forceful case for thinking that the affluent are morally required to devote a substantial proportion of what they have to helping the poor, Garrett Cullity examines, refines and defends an argument of this form. He then identifies its limits.

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)

The Kyoto Protocol on global warming has provoked great controversy in part because it calls for heavier burdens on wealthy countries than on developing countries in the effort to control climate change. The U.S. Senate voted unanimously to oppose any agreement that does not require emissions reductions in low-income countries. The ethics of this position are examined in this paper which shows that there are good moral reasons for supporting the provisions of the Kyoto Protocol. Such a conclusion follows easily (...) from considerations of distributive justice but can also be supported by more narrowly self-interested arguments. (shrink)
