Abstract
(en) In the recent debate about who should provide international climate finance (ICF) to developing countries on concessional terms, some have argued that the ultra-rich should cover a significant proportion of the associated costs. This would apply regardless of the climate responsibilities or level of development of the countries in which the ultra-rich reside. In this article, I examine whether the rich-pay-for-ICF proposal aligns with any reasonable viewpoint on climate justice. To do so, I test the claim against a hybrid model of remedial responsibility for climate change that combines outcome responsibility and the ability to pay. I argue that the rich-pay-for-ICF proposal can be justified on normative grounds by distinguishing between the weighty and frivolous interests of emitters and investors, and by adopting a broad and objective view of equal sacrifice. Finally, I propose a global policy toolbox for implementing the rich-pay-for-ICF proposal in a manner consistent with the aforementioned hybrid model of responsibility.
