Abstract

Kant’s ethics provides surprising resources for addressing duties with respect to climate change. First, I show how Kant’s moral metaphysics, according to which the self is a phenomenon, provides a distinctive ground to mitigate the harm of climate change for future generations. In short, the physical appearances of our actions are grounded in an atemporal existence from which our intrinsic moral value derives. As such, the a priori basis for addressing climate duties to the present is no different from that of duties to address climate duties to the future, though we must consider present circumstances in order to act effectively. Second, I show that recent helpful contributions towards understanding the resources of Kantian ethics for addressing climate face the following prima facie dilemma: perfect duties to reduce emissions are overly demanding because it requires reduction below subsistence levels, while imperfect duties to reduce emissions are not demanding enough to address the climate crisis. Without ruling out the existence of perfect duties to address climate, I analyze the latter horn of the dilemma and show how imperfect duties can be more demanding than one might have thought, given that we are in a climate emergency. Recent work on the role of emergency in Kant’s ethics has shown that there are resources for making sense of the prioritization of some concerns as more pressing. Overall, the aim of this contribution is to highlight some of the prospects and problems that face Kantian approaches to climate ethics.
