Sometimes ignorance is an excuse. If an agent did not know and could not have known that her action would realize some bad outcome, then it is plausible to maintain that she is not to blame for realizing that outcome, even when the act that leads to this outcome is wrong. This general thought can be brought to bear in the context of climate change insofar as we think (a) that the actions of individual agents play some role in realizing (...) climate harms and (b) that these actions are apt targets for being considered right or wrong. Are agents who are ignorant about climate change and the way their actions contribute to it excused because of their ignorance, or is their ignorance culpable? In this paper I examine these questions from the perspective of recent developments in the theories of responsibility for ignorant action and characterize their verdicts. After developing some objections to existing attempts to explore these questions, I characterize two influential theories of moral responsibility and discuss their implications for three different types of ignorance about climate change. I conclude with some recommendations for how we should react to the face of the theories' conflicting verdicts. The answer to the question posed in the title, then, is: "Well, it's complicated.".

This article start from two opposing intuitions in the environmental duties debate. On the one hand, if our lifestyle causes environmental harm, then we have a duty to reduce that impact through lifestyle changes. On the other hand, many people share the intuition that environmental duties cannot demand to alter our lifestyle radically for environmental reasons. These two intuitions underlie the current dualism in the environmental duties debate: those arguing for lifestyle changes and those arguing that our duties are limited (...) to promoting just environmental institutions. The paper has two goals: first, to grasp the underlying reasons for the two intuitions, and, second, to provide a proposal that integrates both intuitions. The paper consists of two main parts. The first part examines the ‘our-duties-should-be-limited’ intuition. Two interpretations are discussed, one under the title ‘what I do make no difference’, dealing with causality and collective action, and one under the title ‘my duty cannot be to change my lifestyle completely’, which discusses demandingness, fairness and value conflict. The second part shows how the ‘lifestyle-matters’ intuition can still play an important role. This part consists of two sections, one on ‘how to make a difference’, which deals with the idea of a cooperative ethos, and the other with ‘why lifestyle matters’, discussing expressive rationality and integrity. These ideas allow giving an important place to lifestyle duties, while avoiding the possible counterproductive effect of a private duties account. (shrink)

In this paper I argue that individuals are, prior to the existence of just institutions requiring that they do so, bound as a matter of global distributive justice to restrict their use, or share the benefits fairly of any use beyond their entitlements, of the Earth’s capacity to absorb greenhouse gases (EAC) to within a specified justifiable range. As part of the search for an adequate account of climate morality, I approach the task by revisiting, and drawing inspiration from, two (...) prominent models from classical political philosophy for thinking about norms (rights, permissions, limits, etc.) regarding “pre-institutional” appropriation of unowned resources; Locke and Kant, respectively. The basic resources they develop—connected to fundamental norms of equality and rights to self-preservation and freedom—in order to generate their particular schema for distributive shares prior to the existence of just institutions can be usefully and plausibly connected up with the scarce, valuable, rival, non-excludable, global, and unowned resource that is EAC in order to undergird a picture of individual climate duties in the contemporary world. It is a picture that comes with some fairly radical implications, especially for the well-off. (shrink)
