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)

Dale Jamieson has claimed that conventional human-directed ethical concepts are an inadequate means for accurately understanding our duty to respond to climate change. Furthermore, he suggests that a responsibility to respect nature can instead provide the appropriate framework with which to understand such a duty. Stephen Gardiner has responded by claiming that climate change is a clear case of ethical responsibility, but the failure of institutions to respond to it creates a (not unprecedented) political problem. In assessing the debate between (...) Gardiner and Jamieson, I develop an analysis which shows a three-part structure to the problem of climate change, in which the problem Gardiner identifies is only one of three sub-problems of climate change. This analysis highlights difficulties with Jamieson’s argument that the duty of respect for nature is necessary for a full understanding of climate ethics, and suggests how a human-directed approach based on the three-part analysis can avoid Jamieson’s charge of inadequacy.

Deep decarbonization – slashing global greenhouse gas emissions to net-zero – now dominates global climate policy. Two recent books assess feasible routes to achieve deep decarbonization. Bill Gates’ How to Avoid a Climate Disaster explains in depth why deep decarbonization requires significant innovations in tech, and Danny Cullenward and David Victor’s Making Climate Policy Work emphasizes the importance of policy innovation (beyond carbon pricing) for driving clean tech breakthroughs. In this critical review essay, I summarize and assess both books. In (...) the final section, I raise several normative questions, which the pair of books might lead us to. (shrink)

Faced with political opponents, proponents of climate justice should consider how politically feasible different principles of climate justice are. I focus in this chapter on the political feasibility of an “ability to pay principle” as a proposal for dividing the burdens of past emissions and emissions from the global poor. I argue that a formulation of an ability to pay principle with a voluntarist scope, restricted only to agreed upon collective goals, is significantly more politically feasible than one with a (...) preventative scope, which focuses on preventing a very bad outcome. A voluntarist ability to pay principle can much more clearly be justified to both constrained policy makers and reactionary citizens as a solution to a collective action problem among states that have already bound themselves to collectively solving the problem. A voluntarist principle also has a stronger precedent as a principle of international law. Thus, those philosophers concerned with the political feasibility of an ability-to-pay principle should carefully consider using a voluntarist rather than a preventative formulation. The chapter proceeds as follows. First, I outline what I mean by “political feasibility” and distinguish it from other conceptions of feasibility. Second, I explore the different rationales for a preventative ability to pay principle. Third, I introduce my voluntarist formulation of the ability to pay principle. I then reply to objections to that formulation, arguing that the drawbacks of a voluntarist formulation are not as dire as they might appear. (shrink)
