What responsibilities does each of us have to reduce or limit our greenhouse gas emissions? Advocates of individual emissions reductions acknowledge that there are limits to what we can reasonably demand from individuals. Climate ethics has not yet systematically explored those limits. Instead, it has become popular to suggest that such judgements should be ‘context-sensitive’ but this does not tell us what role different contextual factors should play in our moral thinking. The current approach to theory development in climate ethics (...) is not likely to be the most effective way to fill this gap. In existing work, climate ethicists use hypothetical cases to consider what can be reasonably demanded of individuals in particular situations. In contrast, ‘climate ethics with an ethnographic sensibility’ uses qualitative social science methods to collect original data in which real individuals describe their own situations. These real-life cases are more realistic, more detailed and cover a broader range of circumstances than hypothetical cases. Normative analysis of real-life cases can help us to develop a more systematic understanding of the role that different contextual factors should play in determining individual climate responsibilities. It can also help us to avoid the twin dangers of ‘idealization’ and ‘special pleading’. (shrink)

In the climate ethics debate, scholars largely agree that individuals should promote institutions that ensure the reduction of greenhouse gas emissions. This paper aims to establish that there are individual duties beyond compliance with and promotion of institutions. Duties of individuals to reduce their emissions are often objected to by arguing that an individual’s emissions do not make a morally relevant difference. We challenge this argument from inconsequentialism in two ways. We first show why the argument also seems to undermine (...) the case for duties to promote institutions that the arguments’ proponents endorse. Second, we argue that individuals ought to cut emissions if they exceed their fair share of emissions entitlements and, by emitting, contribute to climate-related harm. In response to inconsequentialism, we specify the notion of ‘contribution’ via the so-called NESS theory, according to which an act is causally relevant for and contributes to an outcome if it is a Necessary Element of a Set of conditions that is Sufficient for the outcome. After refuting two objections to our approach, we conclude by discussing how to deal with possible conflicts between duties to promote institutions and to reduce one’s emissions. (shrink)

Anthropogenic climate change threatens humanity as a whole, making its mitigation a matter of pressing concern. Mitigation efforts at the institutional level are necessary to successfully change the course of climate change, but thus far governments and industries have been ineffective at reducing greenhouse gas emissions. A point of philosophical contention is whether individuals have a moral responsibility to reduce their own emissions given the lack of institutional action. I argue that they do by redefining climate change as a collective (...) impact. Individual emitters share collective responsibility for that impact, which translates to an individual duty to reduce their contribution. (shrink)

This article substantiates the common intuition that it is wrong to contribute to dangerous climate change for no significant reason. To advance this claim, I first propose a basic principle that one has the moral obligation to act in accordance with the weight of moral reasons. I further claim that there are significant moral reasons for individuals not to emit greenhouse gases, as many other climate ethicists have already argued. Then, I assert that there are often no significant moral (or (...) excusing) reasons to emit greenhouse gases. In any such trivial-cost – but not necessarily trivial-impact – cases, the individual then has an obligation to refrain. Finally, I apply the moral weighing principle to everyday situations of emitting and establish two surprisingly substantial implications: the relevance of virtues to the interpersonal assessment of environmentally harmful actions and the extensive individual ethical obligations that exist short of moral purity.
