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)

Action must be taken to combat climate change. Yet, how the costs of climate action should be allocated among states remains a question. One popular answer—the polluter-pays principle (PPP)—stipulates that those responsible for causing the problem should pay to address it. While intuitively plausible, the PPP has been subjected to withering criticism in recent years. It is timely, following the Paris Agreement, to develop a new version: one that does not focus on historical production-based emissions but rather allocates climate burdens (...) in proportion to each state’s annual consumption-based emissions. This change in carbon accounting results in a fairer and more environmentally effective principle for distributing climate duties. (shrink)

The paper examines two backward-looking principles about how the costs of mitigating and adapting to climate change should be distributed. According to the polluter pays principle, such costs should be borne by those who caused climate change. According to the beneficiary pays principle, they should be borne by those who have benefited from the activities causing climate change, regardless of whether they took part in such activities or not. The paper unpacks both principles, considers their main problems and contends that, (...) when properly combined, they can address such problems. (shrink)
