Historical Emissions and free riding.

Abstract

Should the current members of a community compensate the victims of their ancestor’s emissions of greenhouse gases? I argue that the previous generation of polluters may not have been morally responsible for the harms they caused. I also accept the view that the polluters’ descendants cannot be morally responsible for their ancestor’s harmful emissions. However, I show that, while granting this, a suitably defined notion of moral free-riding may still account for the moral obligation of the polluters’ descendants to compensate the current victims of their ancestors’ actions. A concept of trans- generational free-riding is defined. Objections to the idea of using free-riding as part of a theory of justice are rejected. Two different views of moral free-riding are contrasted, with consequences for the amount of compensation to be exigible from the polluters’ descendants. Some final considerations are devoted to the possible relevance of this free-riding-based view for other issues of historical injustice.
