This article identifies social justice dilemmas associated with the necessity to adapt to climate change, examines how they are currently addressed by the climate change regime, and proposes solutions to overcome prevailing gaps and ambiguities. We argue that the key justice dilemmas of adaptation include responsibility for climate change impacts, the level and burden sharing of assistance to vulnerable countries for adaptation, distribution of assistance between recipient countries and adaptation measures, and fair participation in planning and making decisions on adaptation. (...) We demonstrate how the climate change regime largely omits responsibility but makes a general commitment to assistance. However, the regime has so far failed to operationalise assistance and has made only minor progress towards eliminating obstacles for fair participation. We propose the adoption of four principles for fair adaptation in the climate change regime. These include avoiding dangerous climate change, forward-looking responsibility, putting the most vulnerable first and equal participation of all. We argue that a safe maximum standard of 400–500 ppm of CO2 concentrations in the atmosphere and a carbon tax of $20–50 per carbon equivalent ton could provide the initial instruments for operationalising the principles.

Since the last ice age, when ice enveloped most of the northern continents, the earth has warmed by about five degrees. Within a century, it is likely to warm by another four or five. This revolution in our climate will have immense and mostly harmful effects on the lives of people not yet born. We are inflicting this harm on our descendants by dumping greenhouse gases into the atmosphere. We can mitigate the harm a little by taking measures to control (...) our emissions of these gases, and to adapt to the changes by, for instance, building sea walls around coastlines threatened by rising sea levels. But these measures will be very expensive, and the costs will be born by us, the present generation, whereas the benefits will come to future generations. How much should we sacrifice for the sake of the future? Economists and philosophers have independently worked on the question of our responsibility to future generations. This book brings their work together and applies it to global warming. It suggests a programme for future research on the economic and ethical issues. The book is intended for economists, and for philosophers and other social scientists who have a little knowledge of economic methods. (shrink)

The peculiar features of the climate change problem pose substantial obstacles to our ability to make the hard choices necessary to address it. Climate change involves the convergence of a set of global, intergenerational and theoretical problems. This convergence justifies calling it a 'perfect moral storm'. One consequence of this storm is that, even if the other difficult ethical questions surrounding climate change could be answered, we might still find it difficult to act. For the storm makes us extremely vulnerable (...) to moral corruption. (shrink)

In this book some options concerning the greenhouse effect are assessed from a welfarist point of view: business as usual, stabilization of greenhouse gas emissions and reduction by 25% and by 60%. Up to today only economic analyses of such options are available, which monetize welfare losses. Because this is found to be wanting from a moral point of view, the present study welfarizes (among others) monetary losses on the basis of a hedonistic utilitarianism and other, justice incorporating, welfare ethics. (...) For these welfarist evaluations information about the social consequences of the four options are collected from the literature and eventually corrected; then the consequences for individual well-being are assessed based on psychological research about well-being dependent on the social situation of the individual; finally the aggregation formulas of the respective welfare ethics are applied to these data. Assessments by other types of ethics, e.g. Kantian ethic, are included. The strongest abatement option is found to be optimum with great unanimity. - In addition a cost-welfare analysis of greenhouse gas abatement is undertaken revealing efficient cost-welfare ratios for these measures and the most efficient ratio for the strongest option. - A final, more theoretical part discusses the moral obligations following from such evaluations. The notion of 'moral obligation' is explained in a way that, apart from moral goodness of the required act, reinforcement by formal or informal sanctions is another necessary condition for moral obligations. This leads to a conception of a historical morality according to which the demands of morality rise in the long run. Applying this conception to the greenhouse effect implies that presently we have the moral duty to raise the standards of greenhouse gas abatement as much as is politically feasible. (shrink)

Economics has played an important role in assessing climate change impacts, and the effects of various individual and policy response strategies. Proponents of a key role for economics in analysis of climate change policies and goals argue that its capacity to incorporate and compare a variety of costs and benefits makes it uniquely useful for normative assessment. Critics of economic analysis of climate change have questioned not only its empirical capacities, but also its fundamental usefulness given some of the important (...) but often implicit assumptions on which it is based. After reviewing this debate and its implications for public policy on climate change, the paper sketches a way in which more technical economic analysis and public dialogue might be combined.

The scientific evidence and understanding underpinning societal responsibility for the accelerating pace of climate change has become increasingly strong over the past hundred years. Although many nations have begun to take actions that have the potential to eventually slow the pace of change, contention over the issue continues in the United States, particularly in the nation's capital. A major cause appears to arise from different interpretations of the evidence arising from different perspectives on the issue, including those of the scientific, (...) environmental, fossil-fuel generating, technological, economic and ethical communities. In addition, the public encounters a cacophony of intermixed perspectives from the media and elected officials. While each perspective provides some useful insights, each alone contributes to inhibiting development of the national political consensus needed to responsibly address climate change. Without leadership that balances and reconciles competing perspectives, it is unlikely that a sufficient limiting of emissions will be enacted to prevent significant changes in climate that will impose increasing challenges for those in both developing and developed nations.

Climate change is an ethical issue, because it involves the distribution of a scarce resource – the capacity of the atmosphere to absorb our waste gases without producing consequences that no one wants. Various principles might be used to decide what distribution is just. This commentary argues that on any plausible principle, the industrialised nations should be doing much more than they are doing now, and much more than they are required to do by the Kyoto protocol, to reduce their (...) greenhouse gas emissions. The commentary also responds specifically to some issues raised by MacCracken, Toman and Gardiner, including feasibility, the discount rate, and grounds for pessimism. (shrink)
