Many people are worried about the harmful effects of climate change but nevertheless enjoy some activities that contribute to the emission of greenhouse gas (driving, flying, eating meat, etc.), the main cause of climate change. How should such people make choices between engaging in and refraining from enjoyable greenhouse-gas-emitting activities? In this chapter, we look at the answer provided by decision theory. Some scholars think that the right answer is given by interactive decision theory, or game theory; and moreover think (...) that since private climate decisions are instances of the prisoner’s dilemma, one rationally should engage in these activities provided that one enjoys them. Others think that the right answer is given by expected utility theory, the best-known version of individual decision theory under risk and uncertainty. In this chapter, we review these different answers, with a special focus on the latter answer and the debate it has generated. (shrink)

Some argue that procreation is immoral due to its negative environmental impact. Since living an “eco-gluttonous” lifestyle of excessive resource consumption is wrong in virtue of the fact that it increases greenhouse gas emissions and environmental impact, then bringing another human being into existence must also be wrong, for exactly this same reason. I support this position. It has recently been the subject of criticism, however, primarily on the grounds that such a position (1) is guilty of “double-counting” environmental impacts, (...) and (2) that it over-generalizes to condemn other clearly permissible behaviors, such as saving lives, or certain instances of adoption and immigration. Here, I will defend the environmental argument against procreation from these criticisms. I will do this, first, under the assumption that our individual consumption and emissions cause significant harm. I will then address the problem of causal impotence, and argue that, even if our individual contributions to environmental problems ultimately make no difference to the amount of harm that occurs, procreation is still immoral for many, if not most, of those living in the developed world.

Climate change can be construed as a question of collective responsibility from two different viewpoints: climate change being inherently a collective problem, or collective entities bearing responsibility for climate change. When discussing collective responsibility for climate change, “collective” can thus refer to the problem of climate change itself, or to the entity causing the harm and/or bearing responsibility for it. The first viewpoint focuses on how climate change is a harm that has been caused collectively. Collective action problem refers to (...) an aggregation of individual actions which together produce an outcome that is not intended at the level of an individual action. It cannot be solved by any one agent acting unilaterally. Instead, climate change action must be enacted and supported by numerous agents. The second way to conceptualize climate change as a question of collective responsibility focuses on the collective entities that bear responsibility for climate change. As a global problem, climate change is linked to the realm of international politics, where states, governments, and intergovernmental organizations are the main collective entities. Other important agential collectives in terms of climate responsibility are corporations, including carbon majors who have produced the bulk of emissions. Climate change has also been theorized as a structural injustice, which combines elements from both the viewpoints on what is collective about responsibility for climate change. (shrink)

As a collective action problem, climate change is best tackled by coordination. Most moral philosophers therefore agree on our individual responsibility as political citizens to help establish such coordination. There is disagreement, however, on our individual responsibilities as consumers to reduce emissions before such coordination is established. In this article I argue that from a Kantian deontological perspective we have a perfect duty to refrain from activities that we would not perform if appropriate coordination were established. Moral autonomy means that (...) we do not need to wait for an external lawmaker to tell us what we ought to do. In practice, this means basing our decisions on a shadow price for carbon: if we would not go out for a drive on a sunny Sunday afternoon in a gas-guzzling sport utility vehicle if gas prices were twice as high, we should not do it now. Moreover, we have imperfect duties to reduce emissions by more than our perfect duties require. (shrink)

Many governments are failing to act sufficiently strongly on climate change. Given this, what should motivated affluent individuals in high-consumption societies do? This paper argues that social norms are a particularly valuable target for individual climate action. Within norm-promotion, the paper makes the case for a focus on anti-fossil fuel norms specifically. Section 1 outlines gaps in the existing literature on individuals’ climate change obligations. Section 2 characterises social norms. Section 3 provides seven reasons why social norms are a particularly (...) worthy target for individual climate actors. Section 4 asks which social norms individuals should emphasise, arguing that anti-fossil fuel norms have advantages over emissions reduction and offsetting norms. Section 5 outlines the pathways and mechanisms individuals might exploit to promote anti-fossil fuel norms. (shrink)

All ordinary decisions involve some risk. If I go outside for a walk, I may trip and injure myself. But if I don’t go for a walk, I slightly increase my chances of cardiovascular disease. Typically, we disregard most small risks. When, for practical purposes, is it appropriate for one to ignore risk? This issue looms large because many activities performed by those in wealthy societies, such as driving a car, in some way risk contributing to climate harms. Are these (...) activities morally appropriate? -/- In this paper, I first summarize and respond to some arguments that purport to show that it is appropriate to ignore or discount very small risks. I argue that because our rationality is bounded, it is impossible for us to include every small risk in our decision-making process, and so we may reasonably use heuristics to guide many decisions. However, contrary to some thinkers, I argue that this does not violate the spirit of expected value theory; it merely shows that we should adopt a so-called "two-level" view. Our use of heuristics allows for the reasonable ignoring of some risks, and this perhaps explains why one might be inclined to think that individual climate-related risks are negligible. However, virtually all greenhouse-gas emitting activities in fact have some climate risk on the negative side of the ledger, and the use of heuristics does not permit the general ignoring of climate-change-related risk by individuals on grounds of expediency of judgment and decision-making.

Many have begun to despair that climate justice will prevail even in a minimal form. The affective dimensions of such despair, we suggest, threaten to make climate action appear too demanding. Thus, despair constitutes a moral challenge to individual climate action that has not yet received adequate attention. In response, we defend a duty to act in hope for a more just (climate) future. However, as we see it, this duty falls differentially upon the shoulders of more and less advantaged (...) agents in society. From arguments by Black thinkers like Derrick Bell, we draw a set of distinctions between two types of hope: one for ideal justice, and one for more modest change; and between two types of hopeful actions, those undertaken through formal political channels and those we call 'extra-political' actions; and between two sites of differential moral burdens, those of the privileged and those of the oppressed. Ours is a case for facing even bleak realities, demanding otherwise, and acting in hope to achieve a better future. (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)

With respect to climate change, what is wanted is an account that morally condemns the production of ‘luxury’ greenhouse gas emissions (e.g., joyriding in an SUV), but not ‘subsistence’ emissions (e.g., cooking meals). Now, our individual greenhouse gas emissions either cause harm, or they do not—and those who condemn the production of luxury emissions generally stake their position on the grounds that they do cause harm. Meanwhile, those seeking to defend the moral permissibility of luxury emissions generally do so by (...) arguing that our individual emissions do not cause harm. Here, I argue that, if our individual emissions do cause harm, then this entails too much. For, it entails not only that our luxury emissions are morally impermissible, but that our subsistence emissions are too. This is an undesirable result. Therefore, I propose that we embrace our other option. Namely, I propose that we accept that our individual emissions do not cause harm; or at least, that they make no perceptible difference with respect to the harms associated with climate change. The result of this admission is not as bad as you might think. For, I argue, even if we are individually causally impotent with respect to the harms of climate change, there remains a plausible route toward the moral condemnation of our individual luxury emissions—contrary to what others have argued. What is more, only by accepting our individual causal impotence can we successfully ground the permissibility of our individual subsistence emissions. (shrink)

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)

The tragedy of the commons is a primary contributing factor in ensuring that humanity makes no serious inroads in averting climate change. As a recent Canadian politician pointed out, we could shut down the Canadian economy tomorrow, and it would make no measurable difference in global greenhouse gas emissions. When coordinated effort is required, it would seem that doing the “right thing” alone is irrational: it will harm oneself with no positive consequences as a result. Such is the tragedy. And (...) that is the challenge that we take up here. Though Garrett Hardin suggests that the solution is a governmental process that rules over all contenders, since a world government seems unlikely before the planet hits the tippy point, we suggest an educational initiative instead: one that holds a mirror up to the behaviour of individuals, rather than to the behaviour of individuals in groups. Such an educational initiative would be focused on priming individuals to keep constant track of what they do as individuals as opposed to focusing on the behaviour of humanity in general. Such an educational initiative would focus on tackling the “problem solvers” rather than just “the problem”. (shrink)

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)

Many environmental philosophers have argued that there is an obligation for individuals to reduce their individual carbon footprints. However, few of them have addressed whether this obligation would entail a corresponding duty to limit one’s family size. In this paper, I examine several reasons that one might view procreative acts as an exception to a more general duty to reduce one’s individual greenhouse gas emissions. I conclude that none of these reasons are convincing. Thus, if there is an obligation to (...) reduce one’s unnecessary greenhouse gas emissions, then people should also limit the size of their families when they have the means to do so. (shrink)

Several philosophers deny that an individual person’s emissions of greenhouse gas do any harm; I call these “individual denialists.” I argue that each individual’s emissions may do harm, and that they certainly do expected harm. I respond to the denialists’ arguments.

This article provides theoretical foundations to the widespread intuition that an individual duty to reduce one's carbon emissions should not be overly demanding, and should leave some space to personal life-projects. It does so by looking into the moral structure of aggregative problems such as climate change, and argues that contributing to climate change is less wrong than causing the same amount of harm in paradigm cases of harm-doing. It follows that strong agent-relative reasons, such as consideration of the agent's (...) most important life-projects, are likely sometimes to outweigh the reasons for refraining from contributing to climate change, especially when there is no alternative course of action. This, however, does not mean that individual carbon-emitters are off the hook, since a lot can be done to reduce carbon emissions without jeopardising one's most important life-projects. (shrink)

The topic of my thesis is individual and collective responsibility for collectively caused systemic harms, with climate change as the case study. Can an individual be responsible for these harms, and if so, how? Furthermore, what does it mean to say that a collective is responsible? A related question, and the second main theme, is how ignorance and knowledge affect our responsibility. -/- My aim is to show that despite the various complexities involved, an individual can have responsibility to address (...) climate change. I argue that climate change is not a problem just for states and international bodies, but also for individuals. There are three possible sources of moral responsibility for individuals in relation to climate change harms: direct responsibility (individuals qua individuals), shared responsibility as members (individuals qua members of collective agents), and shared responsibility as constituents (individuals qua constituents of unorganised collectives). -/- Accounts that deny individual responsibility fail to either take our interdependent reality seriously or fail to understand marginal participation (or in the case direct responsibility, fail to appreciate the nature of the climate change phenomenon). Individuals can be complicit in climate change harms, either as members of collective agents (e.g. as citizens of states or employees of a corporation) or as constituents of unorganised collectives (e.g. as consumers or polluters). -/- Although I focus on individual complicity, I do not deny the obligations of collective agents. However, nation-states, governments, and international bodies are not the only relevant collective agents in climate ethics: other collective agents, such as corporations, matter also and can have obligations concerning making sure that their activities are as carbon-neutral as possible. In addition, those corporations that have engaged in lobbying against climate regulation through creating and disseminating misleading information have acquired themselves additional obligations to mitigate climate change and compensate for the harm they have caused. Even so, the ethical claims can only be understood by individual members of these collective agents because only they can feel the pull of moral claims. I suggest that we could distinguish between what one must possess in order to be capable of making moral claims (i.e. moral agency conditions), and what it means to have the ability to exhibit such claims through one’s conduct. -/- Individual direct responsibility is to not to increase the probable risk of serious harm to other people, at least as long as we can do so at a less than significant cost to ourselves. It is limited to relatively wealthy individuals. Offsetting is not a reliable way to meet this duty; we need to look at the emissions from our lifestyle choices (within the available infrastructure). Shared responsibility qua members of collective agents is the key individual responsibility, and it presses especially on those occupying key positions within key collective agents. Saying that, our shared responsibility qua constituents of unorganised collectives has the potential to be decisive in whether some action is taken or not, either through a set of actions that can signal certain acceptance or support, or as a form of political support from the grass roots.

Environmental ethicists have not reached a consensus about whether or not individuals who contribute to climate change have a moral obligation to reduce their personal greenhouse gas emissions. In this paper, I side with those who think that such individuals do have such an obligation by appealing to the concept of integrity. I argue that adopting a political commitment to work toward a collective solution to climate change—a commitment we all ought to share—requires also adopting a personal commitment to reduce (...) one’s emissions. On these grounds, individuals who contribute to climate change have a prima facie moral duty to lower their personal greenhouse gas emissions. After presenting this argument and supporting each of its premises, I defend it from two major lines of objection: skepticism about integrity’s status as a virtue and concerns that the resulting moral duty would be too demanding to be morally required. I then consider the role that an appeal to integrity could play in galvanizing the American public to take personal and political action regarding climate change. (shrink)

There are a number of cases where, collectively, groups cause harm, and yet no single individual’s contribution to the collective makes any difference to the amount of harm that is caused. For instance, though human activity is collectively causing climate change, my individual greenhouse gas emissions are neither necessary nor sufficient for any harm that results from climate change. Some (e.g., Sinnott-Armstrong) take this to indicate that there is no individual moral obligation to reduce emissions. There is a collective action (...) problem here, to which I offer a solution. My solution rests on an argument for a (sometimes) bare moral difference between intending harm and foreseeing with near certainty that harm will result as an unintended side-effect of one’s action. I conclude that we have a moral obligation to reduce our individual emissions; and, more broadly, an obligation to not participate in many other harmful group activities (e.g., factory-farming).

The degradation of natural resources in the environment is, technically speaking, a form of depleting a public good. Public goods are notorious for free-riding among egoists, but the marginality of individual contributions provides no less an obstacle, both to moral duty and motivation. This article discusses the problems of minimized and missing causal involvement on the empirical side; and, in the applicability of classical moral arguments, on the ethical side. It. suggests that individual responsibility is derived on the basis of (...) implicit advantage-taking from participation in collective action. (shrink)

The political representation of future generations would change the relationship between public decisions and the members of democratic political systems. In this paper we examine the implication of these changes on the responsibility of the living members for the future effects of current polices with special reference to climate change. The claim defended is that the collective responsibility of the living members for future outcomes diminishes when public decisions are made less responsive to them. In order to explain why this (...) is the case a ‘participatory account' of collective responsibility is developed according to which collective responsibility is premised on the extent to which public decisions depend on their members. The paper concludes with a discussion on the grounds for valuing collective outcome responsibility and why the conflict between this norm and the claim that future generations should be granted political representation poses fundamental questions about the value of democracy.

Does the decision to relax by taking a drive rather than by taking a walk cause harm? In particular, do the additional carbon emissions caused by such a decision make anyone worse off? Recently several philosophers have argued that the answer is no, and on this basis have gone on to claim that act-consequentialism cannot provide a moral reason for individuals to voluntarily reduce their emissions. The reasoning typically consists of two steps. First, the effect of individual emissions on the (...) weather is miniscule: the planet’s meteorological system is so large, and the size of individual emissions so tiny, that whatever impact an individual emission has on the weather must be vanishingly small. Second, vanishingly small impacts aren’t morally relevant because no one could possibly tell the difference between such an impact occurring and it not occurring. In this paper, we show why both steps are mistaken, and hence why act-consequentialism implies that each of us has an individual obligation to do what we can to stop damaging the climate, including by refraining from, or perhaps by purchasing offsets against, our own individual luxury carbon emissions.

The debate surrounding individual climate duties is divided between collectivists and unilateralists. The fair shares argument is the most influential unilateralist position. In this paper, I demonstrate how a Kantian approach could solve three problems the fair share argument faces. Firstly, the Kantian focus on an agent’s will avoids skepticism regarding the causal connections between individual actions and climate effects. Secondly, a Kantian argument for the imperfect duty to minimally restrict our emissions to an equal share justifies egalitarian fair shares. (...) Thirdly, a Kantian ethical approach has direct political implications, taking away concerns about a distracting focus on individual efforts. (shrink)

This volume bridges contemporary philosophical conceptions of risk and responsibility and offers an extensive examination of the topic. It shows that risk and responsibility combine in ways that give rise to new philosophical questions and problems. Philosophical interest in the relationship between risk and responsibility continues to rise, due in no small part due to environmental crises, emerging technologies, legal developments, and new medical advances. Despite such interest, scholars are just now working out how to conceive of the links between (...) risk and responsibility, the implications that risks may have to conceptions of responsibility (and vice versa), as well as how such theorizing might play out in applied cases. With contributions from leading scholars, this volume brings together new work examining the interplay between risk and responsibility, exploring its varied philosophical aspects and applications to contemporary issues in law, bioethics, technology, and environmental ethics. Risk and Responsibility in Context will be of interest to philosophers working in ethics, bioethics, philosophy of law, and philosophy of technology, as well as scholars and practitioners in law, health and science management, public policy, and environmental studies.

Over the last decade, a number of climate ethicists have turned their attention to the question of individual moral obligations to reduce greenhouse gas emissions. Important problems face their efforts, especially what is called the problem of inconsequentialism. The problems, I argue, arise largely from the failure to treat individual obligations as a matter of justice, a failure that stems from the common modern assumption that justice primarily concerns social institutions. I develop an alternative approach by appealing to the account (...) of justice as a virtue in Thomas Aquinas. This approach allows us to talk about individual obligations to reduce emissions as obligations of justice, even in the current context of institutional failure. At the same time, I argue that approaching climate change in Thomistic terms requires an important modification of Aquinas’s understanding of justice. (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)

Enormous harms, such as climate change, often occur as the result of large numbers of individuals acting separately. In collective action problems, an individual has so little chance of making a difference to these harms that changing their behavior has insignificant expected utility. Even so, it is intuitive that individuals in many collective action problems should not be parts of groups that cause these great harms. This paper gives an account of when we do and do not have obligations to (...) change our behavior in collective action problems. It also addresses a question insufficiently explored in the literature on this topic: when obligations arising out of collective action problems conflict with other obligations, what should we do? The paper explains how to adjudicate conflicts involving two collective action problems and conflicts involving collective action problems and other sorts of obligations. (shrink)

Humans ought to do much more in order to remedy the severe harm caused by climate change. While there seems to be an overall consensus that governments and other national and international political agents need to resolve the problem, there is no agreement yet on the role and responsibility of individuals in this process. In this paper, I suggest an argument of integrity that offers strong pro tanto moral reasons for individuals to reduce their personal greenhouse gas emissions. Hourdequin (2010) (...) has presented an argument of integrity to justify a corresponding obligation. In this paper, I argue that even though Hourdequin’s argument is appealing, it has important limitations. I advance the argument in light of the current literature so that it is not subject to these limitations and establishes an overall more comprehensive justification for why individuals ought to reduce their personal emissions.

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)

Personal carbon footprints have become a subject of major concern among those who worry about global climate change. Conventional wisdom holds that individuals have a duty to reduce their impacts on the climate system by restricting their carbon footprints. However, I defend a new argument for thinking that this conventional wisdom is mistaken. Individuals, I argue, have a duty to take actions to combat the world’s problems. But since climate change is only one of a nearly endless list of such (...) problems, individuals’ obligations to take action as activists do not specifically require reductions in personal carbon footprints. Moreover, this is true even in spite of the fact that we are personally implicated in causing climate change. This paper also argues that many of those who decide to combat climate change by reducing their carbon footprints are likely doing more than they can justify in this regard. Although most people are not doing enough to combat world problems, a proper devotion to activism would seek a balance with other life demands that many climate activists currently eschew. (shrink)

This paper examines how employing the capabilities approach in conceptualizing sustainable development allows reasoning and specifying claims for more sustainable lifestyles. In doing so, it focuses on the example of food consumption because it constitutes an ‘sustainability hotspot’ as well as a paradigmatic example for the tensions between individual lifestyles on the one hand and societal consequences of such lifestyles on the other. The arguments developed in the paper allow rebutting two common objections against claims for individual changes in food (...) consumption. These are, first, that more sustainable food consumption constitutes a societal issue so that asking individuals to behave more sustainably is unnecessary. The second objection argues that such claims infringe on the individuals’ freedom of choice and morally overburden individuals. I first outline a conception of sustainable development that draws on the capabilities approach. Subsequently, I develop a more specific account of what is meant by more sustainable food production and consumption. Finally, I draw on this account to rebut the above-mentioned objections against claims for more sustainable food consumption. (shrink)

Humans are causing global climate change (GCC), and such climate change causes harms. Robin Attfield explained how individuals should be understood to be culpable for these harms. In this paper, I use a critical analysis of Attfield’s explanatory framework to explore further difficulties in accounting for corporate responsibility for these harms. I begin by arguing that there are some problems with his framework as it is applied to individuals that emit greenhouse gases (GHGs). I then show that it will be (...) very difficult to extend this framework to corporations. This is not a criticism of Attfield’s work (as he does not discuss corporate responsibility for those harms associated with GCC), but it will serve to show the difficulty in philosophically explaining corporations’ moral culpability when it comes to these harms. In fact, one positive conclusion of this paper is that it highlights a new area of concern that has been ignored in discussions of corporate responsibilities—that of mediated responsibilities—which is how Attfield understands our responsibilities regarding GCC. The discussion of this concern will draw attention to another positive conclusion of this paper: the harms associated with CO2 are very unlike the harms associated with other airborne-emitted substances, which will indicate that we will need new ways of understanding how individuals and corporations are philosophically responsible for these harms. The final positive conclusion of this paper will be a discussion of what the constraints should be on new approaches to explaining our culpability. (shrink)

Six planetary boundaries have already been exceeded, including climate change, loss of biodiversity, chemical pollution, and land-system change. The health research sector contributes to the environmental crisis we are facing, though to a lesser extent than healthcare or agriculture sectors. It could take steps to reduce its environmental impact but generally has not done so, even as the planetary emergency worsens. So far, the normative case for why the health research sector should rectify that failure has not been made. This (...) paper argues strong philosophical grounds, derived from theories of health and social justice, exist to support the claim that the sector has a duty to avoid or minimise causing or contributing to ecological harms that threaten human health or worsen health inequity. The paper next develops ideas about the duty’s content, explaining why it should entail more than reducing carbon emissions, and considers what limits might be placed on the duty. (shrink)

This work employs Elizabeth Cripps’ collectivist account of responsibility for climate change in order to ground an individual duty to reduce one’s GHG emissions. This is significant not only as a critique of Cripps, but also as an indication that even on some collectivist footings, individuals can be assigned primary duties to reduce their emissions. Following Cripps, this work holds the unstructured group of GHG emitters weakly collectively responsible for climate change harms. However, it argues against Cripps that what follows (...) from this is a corresponding collective duty to act qua group to bring about an end to the harm and a derivative duty for each emitter to promote the required organization of a group capable of this. Instead, this work argues that acts of GHG emission, to the extent that they are avoidable and performed with requisite knowledge, make one into a member of a group that is morally responsible for climate-related harms. Thus, individual emitters who can do otherwise should recognize themselves as members of a group that collectively harms. Subsequently, they should take all possible steps in order to renounce their membership (e.g. by reducing their GHG emissions). (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.

This essay addresses moral aspects of using carbon offsets for counteracting individuals’ luxury emissions. After introducing and outlining the main topics and terms related to carbon offsetting, this essay answers three objections that have been levied against carbon offsetting: objections from the indulgences analogy, objections from the directness of the duty not to harm, and separateness objections. The essay argues that advocates for offsetting have resources to defend against these criticisms by pointing to particularities of individual emissions’ harmfulness, as well (...) as the preemptive nature of offsetting. The essay then shows that in spite of these defenses there is reason to regard not emitting as a better option because of a host of problems that plague offsetting in its current forms. The essay concludes that offsetting enhances individuals’ options for discharging their duty not to harm, but that standards of justice and efficacy need to be adopted. (shrink)

I defend the view that individual agents have instrumental moral reasons for and against contributing to collective actions. I distinguish three versions of this view found in the literature and argue that only one withstands scrutiny: the version on which each individual contribution to a collective action is a cause of the latter’s large-scale outcomes. The central difficulty with this view is its apparent incompatibility with leading theories of causation. Against these theories I motivate a general structural principle about causation (...) which enables instrumentalism to deliver the intuitively correct verdicts about individual agents’ moral reasons in cases of collective action.

Journal of Social Philosophy, EarlyView.

According to the counterfactual comparative account, an event harms a person if and only if it makes things worse for her. Cases of overdetermination and preemption pose a serious challenge to CCA since, in these cases, although it is evident that people are harmed, there are no individual events that harm them. However, while there are no individual events that make people worse off in cases of overdetermination and preemption, there are pluralities of events that do so. In light of (...) this feature of these cases, several philosophers have suggested that it is these pluralities that do the harming. In this article, I will argue that although the most prominent accounts of plural harm – e.g., Neil Feit’s account – fare better than one might initially think, they fail to deal adequately with a number of intriguing cases of preemption first introduced by Alastair Norcross. I will also introduce a new view on plural harm and argue that this view, apart from dealing with the cases of overdetermination and preemption that the other accounts of plural harm handle, also deals adequately with Norcross’s cases.

Most philosophers and psychologists who have explored the psychology of climate change have focused only on motivational issues—getting people to act on what morality requires of them. This is misleading, however, because there are other psychological processes directed not at motivation but rather our ability to grasp the implications of climate change in a general way—what Stephen Gardiner has called the ‘grasping problem’. Taking the grasping problem as my departure point, I draw two conclusions from the relevant psychological literature: 1) (...) ethicists and policy makers should focus less on changing individuals’ behaviors and more on changing policy; and 2) even though solutions to climate change must come at the level of policy, progress on this front will be limited by incompatible moral norms.

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)

Do I cause global warming, climate change and their related harms when I go for a leisure drive with my gas-guzzling car? The current verdict seems to be that I do not; the emissions produced by my drive are much too insignificant to make a difference for the occurrence of global warming and its related harms. I argue that our verdict on this issue depends on what we mean by ‘causation’. If we for instance assume a simple counterfactual analysis of (...) causation according to which ‘C causes E’ means ‘if C had not occurred, E would not have occurred’, we must conclude that a single drive does not cause global warming. However, this analysis of causation is well-known for giving counterintuitive results in some important cases. If we instead adopt Lewis’s analysis of causation, it turns out that it is indeterminate whether I cause global warming when I go for a single drive. Still, in contexts where we seek to control or understand global warming, there is a pressure to adopt a more fragile view of this event. When we adopt such a view, it turns out that a single drive does cause global warming. This means that we cannot like Sinnott-Armstrong and Kingston and Sinnott-Armstrong reject the idea that I should refrain from going for a leisure drive simply because such a drive does not cause global warming.

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 paper discusses the moral justification behind placing a tax on foods in correlation with their greenhouse gas emissions. The background is a report from 2016 by the Danish Council of Ethics promoting a national tax on the consumption of meat from ruminants as an initial step to curb the 19–29% of total anthropogenic greenhouse gas emissions stemming from the food sector. The paper describes the contribution of food production and consumption to climate change and how a change in diet, (...) away from ruminant meat in particular, could lead to substantial reductions in GHG emissions from food production and consumption. We discuss whether, given the anticipated effects on humans and the nature of climate change, individual consumers have a moral responsibility to change their diet and/or whether governments are justified in restricting the individual consumer’s freedom of choice through taxation in order to effectively reduce emissions. The paper concludes that such an intervention is warranted and necessary, both from an efficiency perspective and from an ethical perspective. (shrink)
