This paper adopts justificatory moral pluralism – a multilevel framework for justifying the choice by different agents of the most appropriate norms and values to guide their decisions and actions – to climate change. Its main objective is to investigate how ethics may effectively help achieve a better result in deciding how to mitigate, adapt, or compensate by enhancing the moral acceptability of the available policies or actions that are most likely to counter the effects of climate change. JMP presents (...) agents – individuals, nonstate, and state – with a thorough yet flexible process of matching policies and actions with ethical theories, raising the robustness of moral reasons for politically efficient and individually motivating courses of action against climate change. JMP triggers climate responsibility and sensibility in agents, engaging them in discussing and finding out individually and collectively the most acceptable paths for the decarbonisation transition that is fast approaching.
