Recent work in applied ethics has advanced a raft of arguments regarding individual responsibilities to address collective challenges like climate change or the welfare and environmental impacts of meat production. Frequently, such arguments suggest that individual actors have a responsibility to be more conscientious with their consumption decisions, that they can and should harness the power of the market to bring about a desired outcome. A common response to these arguments, and a challenge in particular to act-consequentialist reasoning, is that (...) it “makes no difference” if one takes conscious consumption action or not – that one is “causally impotent” to change an outcome. In this paper, I break causal impotence objections into three distinct lines of argument and present causal indeterminacy as a third, unexplored variation of much more common causal impotence lines. I suggest that the causal indeterminacy argument presents additional challenges to consequentialist moral theory because it acknowledges that individual actions can have an impact on outcome, but suggests instead that the outcome can neither be known nor secured by the action itself.

In order for states to fulfil their moral duties, costs must be passed to individual citizens. This paper asks how these costs should be distributed. I advocate the common-sense answer: the distribution of costs should, insofar as possible, track the reasons behind the state’s duty. This answer faces a number of problems, which I attempt to solve.

According to some scholars, while sets of greenhouse gases emissions generate harms deriving from climate change, which can be mitigated through collective actions, individual emissions and mitigation activities seem to be causally insufficient to cause harms. If so, single individuals are neither responsible for climate harms, nor they have mitigation duties. If this view were true, there would be collective responsibility for climate harms without individual responsibility and collective mitigation duties without individual duties: this is puzzling. This paper explores a (...) way to solve this puzzle. First, it will be argued that individual emissions, though not proper and full-fledged causes, causally contribute to raise the probability of climate harms. As a consequence, individuals are in fact responsible for their expected contributions to climate harms – this is contributive responsibility for likely outcomes. Second, it will be argued that people have responsibility also for the possible impacts of their individual emissions on climate harms. People can plausibly be regarded as individually responsible for the possible outcomes of their actions in close possible alternative worlds – this is robust responsibility. Non-causal individual responsibility for climate harms is plausible, and the puzzle may be solved. (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)
