The environmental crisis challenges the adequacy of traditional moral theories, particularly in the case of act consequentialism – the view that an act is morally right if and only if it brings about the best available outcome. Although anthropogenic climate change threatens the well-being of billions of humans and trillions of non-human animals, it is difficult for an act consequentialist to condemn actions that contribute to it, as each individual action makes no difference to the probability of whether climate change (...) will occur. Or so one argument goes. This chapter examines the limits and possibilities of a consequentialist approach to climate ethics. It discusses various types of consequentialist theories applicable to the current environmental situation. It outlines outcome-based strategies to address the no-difference problem and to promote individual climate action. Finally, it considers environmental cases of evaluative uncertainty and how a consequentialist could deal with them. (shrink)

ABSTRACT Offsetting is a very ineffective way to do good. Offsetting your lifetime emissions may increase aggregated life expectancy by at most seven years, while giving the amount it costs to offset your lifetime emissions to a malaria charity saves in expectation the life of at least one child. Is there any moral reason to offset rather than giving to some charity that does good so much more effectively? There might be such a reason if your offsetting compensated or somehow (...) benefitted the victims of your emission, since that could mean that you would satisfy the duty not to harm others by emitting and offsetting. But that is typically not true. If your emission harms some person and your offsetting benefits some person, then these are most likely different people. Hence, I conclude, we have a stronger reason to give to effective charities than we have to offset our emissions. (shrink)

Why should we refrain from doing things that, taken collectively, are environmentally destructive, if our individual acts seem almost certain to make no difference? According to the expected consequences approach, we should refrain from doing these things because our individual acts have small risks of causing great harm, which outweigh the expected benefits of performing them. Several authors have argued convincingly that this provides a plausible account of our moral reasons to do things like vote for policies that will reduce (...) our countries’ greenhouse gas emissions, adopt plant-based diets, and otherwise reduce our individual emissions. But this approach has recently been challenged by authors like Bernward Gesang and Julia Nefsky. Gesang contends that it may be genuinely impossible for our individual emissions to make a morally relevant difference. Nefsky argues more generally that the expected consequences approach cannot adequately explain our reasons not to do things if there is no precise fact of the matter about whether their outcomes are harmful. -/- In the following chapter, author Howard Nye defends the expected consequences approach against these objections. Nye contends that Gesang has shown at most that our emissions could have metaphysically indeterministic effects that lack precise objective chances. He argues, moreover, that the expected consequences approach can draw upon existing extensions to cases of indeterminism and imprecise probabilities to deliver the result that we have the same moral reasons to reduce our emissions in Gesang’s scenario as in deterministic scenarios. Nye also shows how the expected consequences approach can draw upon these extensions to handle Nefsky’s concern about the absence of precise facts concerning whether the outcomes of certain acts are harmful. The author concludes that the expected consequences approach provides a fully adequate account of our moral reasons to take both political and personal action to reduce our ecological footprints.

Many morally significant outcomes can be brought about only if several individuals contribute to them. However, individual contributions to collective outcomes often fail to have morally significant effects on their own. Some have concluded from this that it is permissible to do nothing. What I call ‘the problem of insignificant hands’ is the challenge of determining whether and when people are obligated to contribute. For this to be the case, I argue, the prospect of helping to bring about the outcome (...) has to be good enough. Furthermore, the individual must be in a position to increase the probability of its being brought about to an appropriate extent. Finally, I argue that when too few are willing to contribute, people may have a duty to increase their number. Thus, someone can be obligated to contribute or to get others to contribute. This prospect account is consistent with Kantianism, contractualism and rule consequentialism but inconsistent with act consequentialism. (shrink)

Climate change compels us to rethink the ethics of our dietary choices and has become an interesting issue for ethicists concerned about diets, including animal ethicists. The defenders of veganism have found that climate change provides a new reason to support their cause because many animal-based foods have high greenhouse gas emissions. The new style of argumentation, the ‘climatic argument for veganism’, may benefit animals by persuading even those who are not concerned about animals themselves but worry about climate change. (...) The arguments about the high emissions of animal-based food, and a resulting moral obligation to abstain from eating such products, are an addition to the prior forms of argument for principled veganism grounded on the moral standing of, and concern for, nonhuman animals. In this paper, we examine whether the climatic argument for veganism is convincing. We propose a formulation for the amended version of the argument and discuss its implications and differences compared to the moral obligations of principled veganism. We also reflect upon the implications of our findings on agricultural and food ethics more generally. (shrink)

Many economists have argued convincingly that automated systems employing present-day artificial intelligence have already caused massive technological displacement, which has led to stagnant real wages, fewer middle- income jobs, and increased economic inequality in developed countries like Canada and the United States. To address this problem various individuals have proposed measures to increase workers’ living standards, including the adoption of a universal basic income, increased public investment in education, increased minimum wages, increased worker control of firms, and investment in a (...) Green New Deal that will provide substantial employment in transitioning to green energy, buildings, and agriculture. In this paper I argue that both left-wing and right-wing positions in political philosophy, such as John Rawls’s Justice as Fairness and Robert Nozick’s Entitlement Theory, are committed to the conclusion that we should take political action to counteract the effects of technological displacement by undertaking such measures to increase workers’ living standards.

This paper discusses the inefficacy problem that arises in contexts of “collective harm.‘ These are contexts in which by acting in a certain sort of way, people collectively cause harm, or fail to prevent it, but no individual act of the relevant sort seems to itself make a difference. The inefficacy problem is that if acting in the relevant way won’t make a difference, it’s unclear why it would be wrong. Each individual can argue, “things will be just as bad (...) whether or not I act in this way, so there’s no point in doing otherwise.‘ The goal of this paper is to give an overview of some of the main responses available to the problem and to highlight central issues that arise for each type of response. In the final section, I explain what I take to be the most promising strategy and discuss the form that this strategy should take. (shrink)

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)

Our thesis is that there is no moral requirement to refrain from emitting reasonable amounts of greenhouse gases solely in order to enjoy oneself. Joyriding in a gas guzzler provides our paradigm example. We first distinguish this claim that there is no moral requirement to refrain from joyguzzling from other more radical claims. We then review several different proposed objections to our view. These include: the claim that joyguzzling exemplifies a vice, causes or contributes to harm, has negative expected value, (...) exceeds our fair share of global emissions, and undermines political duties. We show why none of these objections succeeds and conclude that no good reason has yet been proposed that shows why joyguzzling violates a moral requirement. (shrink)

An anthropocentric scope for clinical medical ethics (CME) has largely separated this area of bioethics from environmental concerns. In this article, we first identify and reconcile the ethical issues imposed on CME by climate change including the dispersion of related causes and effects, the transdisciplinary and transhuman nature of climate change, and the historic divorce of CME from the environment. We then establish how several moral theories undergirding modern CME, such as virtue ethics, feminist ethics, and several theories of justice, (...) promote both a flourishing of human medical practice and the environment. We conclude by defining an expanded the scope of CME as inclusive of not only patients, families, physicians, and other health professionals but other humans, non-humans, and their shared environment. We then apply this scope and theory to a widely used framework for applying CME, the Four Topics model, to construct a climate conscious approach to CME. (shrink)

The extent of our duties to mitigate climate change is commonly conceptualized in terms of temperature goals like the 1.5°C and the 2°C target and corresponding emissions budgets. While I do acknowledge the political advantages of any framework that is relatively easy to understand, I argue that this particular framework does not capture the true extent of our mitigation duties. Instead I argue for a more differentiated approach that is based on the well-known distinction between subsistence and luxury emissions. At (...) the heart of this approach lies the argument that we have no budget of substantial, net-positive luxury emissions left. In a world in which dangerous climate change has begun, we must expect all further substantial, net-positive luxury emissions to cause harm. Since they lack the kind of justification needed for them to be nevertheless permissible, I conclude that we must stop emitting them with immediate effect. I also briefly discuss the difficult case of subsistence emissions and offer some first thoughts on the morality of a third category of emissions, what I call ‘transition emissions’. (shrink)

Since materially opulent lifestyles are a significant cause of environmental degradation, environmentalists often call for us to live more simply. This call is typically focused on consumption. But our environmental footprint is a function of our paid work as well as our purchases. Consequently, environmentalists should also urge us to work less. Defending this claim is the project of this paper. Reducing our economic productivity, I argue, can often be expected to make both the world and our characters better. And, (...) contrary to what some have suggested, working less than is normal needn’t involve unfairly free-riding on the productive efforts of others. (shrink)

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.".

Climate change and many environmental problems are caused by the accumulated effects of repeated actions by multiple individuals. Instead of relying on collective responsibility, I argue for a non-atomistic individual responsibility towards such environmental problems, encompassing omissions, ways of life, and consequences mediated by other agents. I suggest that the degree of causal responsibility of the agent must be balanced with the degree of capacity-responsibility determined by the availability of doable alternatives. Then, the more an agent has powers as a (...) group member, the more she is responsible to design the social structure and the infrastructures of the group towards sustainability. Finally, one can hold another agent responsible only if the accused is not in a vulnerable position and if she is capable to take reparative and adaptive actions. (shrink)
