Abstract

This chapter turns to the question of historical responsibility for unavoided climate impacts. It introduces the climate debt claim, according to which certain wealthy or industrialized states owe a debt of compensation to some of those suffering from the unavoided impacts of climate change; where the notion of a debt indicates that the obligation in question falls within the domain of rectificatory justice. The Historical Emissions Debt view, according to which climate debts arise when parties emit more than their fair share of greenhouse gases, is rejected on the basis that there is no fair shares principle for historical use of the climate sink considered in isolation. Two interpretations of the beneficiary pays principle are found to face similar problems. Since none of these accounts appear defensible, it is concluded that those seeking to substantiate a climate debt claim would do better to attempt this by other means.
