Abstract

Within the last two decades, a philosophical field of individual climate ethics has taken off. This subdiscipline interrogates the individual’s moral responsibility in causing and preventing climate harm. On the one hand, environmental movements have long emphasized the importance of individual lifestyle changes in solving collective action problems like air pollution. In this tradition, personal obligations to reduce carbon emissions are well-founded. This is the climate individualist view. Against this thinking, skeptics of climate individualism argue that unilateral emissions reductions will not make a difference to climate harms and insist that individuals instead have moral obligations to promote effective institutions through collective action. This is the climate collectivist camp. Climate individualists have replied to the climate collectivist’s charge in two ways. First, they have denied the description by arguing that individual emitting behaviors do cause harm or otherwise might make a difference. Second, they have denied the prescription by arguing that individual emissions reductions are required even if they do not make a difference. This chapter critically summarizes the arguments that have arisen in this debate, including the problem of inconsequentialism, the moral grounds of collective responsibility, and noncausal accounts of individual responsibility for climate harms. Ultimately, this chapter identifies a consensus in the literature that climate individualism is correct. It then turns to the emerging and contested discussion regarding the extent of individual obligations to minimize contribution to climate harms.
