Nation-states are seen as reasonable candidates to whom to assign remedial responsibilities for climate change harms. A natural question arises: Based on what justification should these responsibilities be assigned to states? Three prominent principles have been proposed: the “Polluter pays,” the “Beneficiary pays,” and the “Ability to pay.” However, each principle faces important objections when considered in isolation. Building on David Miller's multi-principle theory of remedial responsibility, I propose and justify an account of remedial responsibility for the case of climate (...) change. I complement the account with a guiding algorithm that arranges these (and more) principles in a systematic way to make remedial responsibilities for climate change harms applicable. This guiding algorithm resolves the objections that arise when the principles are applied in isolation. (shrink)
