What requirements does morality impose on us in relation to climate change? This question can be asked of individuals, of the entire global population, and of groups of various sizes in between. Given the case for accepting that we all collectively ought to be causing less climate-affecting pollution than we do, what follows from that about the moral status of the actions of members of the larger group? I examine two main ways in which moral requirements on group members can derive from requirements that apply to the larger group. But neither of them seems to apply to the case of climate-affecting pollution. Perhaps this is a case where we together act wrongly, although no-one’s contribution to our doing so is wrong.

This paper presents a moral philosophical account of free riding, specifying the conditions under which failing to pay for nonrival goods is unfair. These conditions do not include the voluntary acceptance of the goods: this controversial claim is supported on the strength of a characterization of the kind of unfairness displayed in paradigm cases of free riding. Thus a "Principle of Fairness" can potentially serve as a foundation for political obligations. The paper also discusses the relation between its moral philosophical account of free riding, and a game theoretic or economic account.
