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)

Carbon offsetting remains contentious within, at least, philosophy. By posing and then answering a general question about an aspect of the morality of carbon offsetting—Does carbon offsetting make luxury emissions morally permissible?—this essay helps to lessen some of the topic’s contentiousness. Its central question is answered by arguing and defending the view that carbon offsetting makes luxury emissions morally permissible by counteracting potential harm. This essay then shows how this argument links to and offers a common starting point for further (...) examination of offsetting across various disciplines and domains, such as policy and other branches of philosophy like the ethics of risk.

In this paper, we defend three claims about what it will take for an AI system to be a basic moral patient to whom we can owe duties of non-maleficence not to harm her and duties of beneficence to benefit her: (1) Moral patients are mental patients; (2) Mental patients are true intentional systems; and (3) True intentional systems are systematically flexible. We suggest that we should be particularly alert to the possibility of such systematically flexible true intentional systems developing (...) in the areas of exploratory robots and artificial personal assistants. Finally, we argue that in light of our failure to respect the well-being of existing biological moral patients and worries about our limited resources, there are compelling moral reasons to treat artificial moral patiency as something to be avoided at least for now.

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)

First, with respect to our personal relationship to fossil fuels, this chapter introduces arguments about whether we should or even can address our own usage of fossil fuels. This involves determining whether offsetting emissions is morally required and practically possible. Second, with respect to our relationship with fossil fuels at the national level, it discusses forms of local resistance, especially divestment and pipeline protesting. Finally, with respect to our relationship with fossil fuels at the international level, it considers two types (...) of policy. On the one hand, some have argued that we should stop most trade in oil, on the basis that most oil that is traded is not subject to the control of citizens. On the other hand, some have argued that we should price the costs of fossil fuels so that there are market incentives to avoid digging them out of the ground. (shrink)

Many of us believe that we can and do have individual obligations to refrain from contributing to massive collective harms – say, from producing luxury greenhouse gas (GHG) emissions; however, our individual actions are so small as to be practically meaningless. Can we then, justify the intuition that we ought to refrain? In this paper, we argue that this debate may have been mis-framed. Rather than investigating whether or not we have obligations to refrain from contributing to collective action, perhaps (...) we should ask whether we have reason to do so. However, this framing brings challenges of its own, and so we close by asking what problems are generated if we focus on these questions of ‘contributory ethics’. (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.

Greenhouse-gas emissions are indirectly causing future deaths by multiple mechanisms. For example, reduced food and water supplies will exacerbate hunger, disease, violence, and migration. How will anthropogenic global warming (AGW) affect global mortality due to poverty around and beyond 2100? Roughly, how much burned fossil carbon corresponds to one future death? What are the psychological, medical, political, and economic implications? Predicted death tolls are crucial for policy formulation, but uncertainty increases with temporal distance from the present and estimates may be (...) biased. Order-of-magnitude estimates should refer to literature from diverse relevant disciplines. The carbon budget for 2°C AGW (roughly 10 12 tonnes carbon) will indirectly cause roughly 10 9 future premature deaths (10% of projected maximum global population), spread over one to two centuries. This zeroth-order prediction is relative and in addition to existing preventable death rates. It lies between likely best- and worst-case scenarios of roughly 3 × 10 8 and 3 × 10 9, corresponding to plus/minus one standard deviation on a logarithmic scale in a Gaussian probability distribution. It implies that one future premature death is caused every time roughly 1,000 (300–3,000) tonnes of carbon are burned. Therefore, any fossil-fuel project that burns millions of tons of carbon is probably indirectly killing thousands of future people. The prediction may be considered valid, accounting for multiple indirect links between AGW and death rates in a top-down approach, but unreliable due to the uncertainty of climate change feedback and interactions between physical, biological, social, and political climate impacts (e.g., ecological cascade effects and co-extinction). Given universal agreement on the value of human lives, a death toll of this unprecedented magnitude must be avoided at all costs. As a clear political message, the “1,000-tonne rule” can be used to defend human rights, especially in developing countries, and to clarify that climate change is primarily a human rights issue.

Several philosophers have argued that human enhancements should be considered a potential solution to climate change. In this paper, I consider one such argument offered by S. Matthew Liao, Anders Sandberg, and Rebecca Roache. I argue that, while their argument is plausible, we have an even stronger reason to consider enhancements a potential solution. In particular, enhancements could align our interests with the promotion of a proper response to climate change: if enhancements were in our interest to adopt and also (...) reduced the pernicious effects of climate change, then it would, indirectly, become in our interest to reduce those effects.

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 seem to be good reasons that democratic institutions must be reformed in order to minimize the danger of unsustainable policy decisions infringing upon duties of intergenerational justice. This is why there exist a number of different proposals of how to reform democratic states in order to foster their duties towards the future. However, the debate lacks a systematic assessment of these suggested reforms within a coherent theoretical and norma-tive framework. This paper aims at developing such a framework. We suggest (...) two conceptual dimensions defining the spectrum of different justi-fiable institutional reforms: the relation between democracy and justice as one dimension and the conditions considered relevant for viewing democracies as responsible collective agents as the other. Depending on how we understand this relation and these conditions, it is possible to substantiate a set of types of institutional reforms that will promote democracies’ capacities to comply with their responsibilities towards the future.

It is widely assumed that people have a moral right to procreate. This article explores recent arguments in opposition to procreation in some or all contexts. Some such views are concerned with the risks and harms of life that procreation imposes on non-consenting children. Others articulate concerns for third parties – the environmental damage or opportunity costs that procreation poses to already existing people. The article then surveys arguments that favor procreation despite the risks to the children created and third (...) parties. The best argument for procreation is based on the significant interest people have in forming the parent–child relationship. An important under-discussed middle ground is suggested – one that avoids the criticisms of the anti-natalist while fulfilling the best aims of procreation – viz. adoption. The duty to adopt is summarized and objections to it considered. Thoughtful people who deeply desire to become parents but do not wish to participate in the range of potential procreative harms should consider adoption as a first choice. (shrink)

This dissertation is a contribution to the debate about ‘climate justice’, i.e. a call for a just and feasible distribution of responsibility for addressing climate change. The main argument is a proposal for a cautious, practicable, and necessary step in the right direction: given the set of theoretical and practical obstacles to climate justice, we must begin by making contemporary development practices sustainable. In times of climate change, this is done by recognising and responding to the fact that emissions of (...) greenhouse gases, with climate change as their result, are an immanent threat to any reflectively embraced development project. In the universal pursuit of progress, basic needs of both present and future people are put at risk. Even so, a political stalemate and business-as-usual prevail. The situation is locked up by an uncertainty about the exact impacts of choices made and by the reasonable disagreement of modern societies. The result is passiveness, and the passing on of a slowly and indiscernibly growing problem to future generations. This dissertation brings out a crucial message about the need to make our development sustainable. Instead of delaying action through trying to resolve the intractable epistemic and normative uncertainty fully, the focus should be on vindicating already shared points of practical convergence. On the constructivist method here adopted, the task is to characterise the agent and the situation faced from a practical and first-person point of view. More specifically, to specify the practical problem climate change gives rise to; the moral importance of needs (chapter three); how a principled priority of basic needs can be defended (chapter four), intergenerationally (chapter five) and internationally (chapter six); and what natural and social limits there are to development (chapter seven). These conceptions narrows the practice of development in the present context: it can be concluded that development must not risk the basic needs of anyone implicated. This common ground brackets off disagreement irrelevant to the urgent need to act, and so brings together otherwise deeply divided agents. A sufficientarian basic needs-principle, as the focus of an overlapping consensus, is practicable and anticipatory in the disuniting moral conundrum of climate change. (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.

It is widely recognized that lives and activities can be meaningful or meaningless, but few have appreciated that they can also be anti-meaningful. Anti-meaning is the polar opposite of meaning. Our purpose in this essay is to examine the nature and importance of this new and unfamiliar topic. In the first part, we sketch four theories of anti-meaning that correspond to leading theories of meaning. In the second part, we argue that anti-meaning has significance not only for our attempts to (...) theorize about meaning in life, but also for our ability to lead meaningful lives in the modern world.

Anthropogenic climate change has become a hot button issue in the scientific, economic, political, and ethical sectors. While the science behind climate change is clear, responses in the economic and political realms have been unfulfilling. On the economic front, companies have marketed themselves as pioneers in the quest to go green while simultaneously engaging in environmentally destructive practices and on the political front, politicians have failed to make any significant global progress. I argue that climate change needs to be framed (...) as an ethical issue to make serious progress towards the path to a sustainable human civilization. In an effort to motivate the urgency needed to confront climate change, I argue that climate change seriously affects human beings living here and now, and if one cares about unnecessarily harming fellow innocent living human beings, then one should care about one’s own environmental impact related to climate change. Since this argument does not depend upon any specific philosophical, religious, or ethical tradition but applies regardless of one’s particular background, I hope to induce genuine concern among all human beings regarding this issue.

Obligations to reduce one’s green house gas emissions appear to be difficult to justify prior to large-scale collective action because an individual’s emissions have virtually no impact on the environmental problem. However, I show that individuals’ emissions choices raise the question of whether or not they can be justified as fair use of what remains of a safe global emissions budget. This is true both before and after major mitigation efforts are in place. Nevertheless, it remains difficult to establish an (...) obligation to reduce personal emissions because it appears unlikely that governments will in fact maintain safe emissions budgets. The result, I claim, is that under current conditions we lack outcome, fairness, promotional, virtue or duty based grounds for seeing personal emissions reductions as morally obligatory. (shrink)

By providing an explicit estimate of the harms caused by personal greenhouse gas emissions, John Nolt (in his “How Harmful are the Average American’s Greenhouse Gas Emissions?”) hopes to undermine tendencies to downplay these emissions and their impacts on global climate change. He estimates that an average American would be responsible for one two-billionth of the suffering or death of two billion people (over 1000 years). He treats this as equivalent to being responsible for the suffering or death of one (...) person. In my paper I argue that these are not equivalent, and that the former is less problematic than the latter. I end with the suggestion that, in terms of personal emissions, having fewer children is more effective than merely reducing our current emissions. (shrink)

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)

The potential upscaling of carbon dioxide removal (CDR) technologies to meet states’ net-zero targets may enable individuals to remove emissions by purchasing carbon removal certificates. In this paper, I argue for two concepts of individual responsibility to capture the moral responsibility of individuals to remove carbon dioxide from the atmosphere through CDR technologies. The first is that of liability, a direct responsibility to remove carbon in order to minimize one’s carbon footprint. The second is a shared political responsibility to remove (...) carbon that individuals have by virtue of being part of weak collectives responsible for mitigating climate change or by virtue of participating in structures that contribute to climate change. I argue that the concept of shared political responsibility can be used to determine how CDR technologies should or should not be implemented. Finally, I discuss how these two responsibilities are related. (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.

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)

We argue that the prudential benefits of long-distance leisure travel can justify such trips even though there are strong and important reasons against long-distance flying. This is because prudential benefits can render otherwise impermissible actions permissible, and because, according to dominant theories about wellbeing, long-distance leisure travel provides significant prudential benefits. However, this ‘wellbeing argument’ for long-distance leisure travel must be qualified in two ways. First, because travellers are epistemically privileged with respect to knowledge about what is good for them, (...) they must look critically at their own assessment of the prudential benefits of a trip. Second, the wellbeing argument is unlikely to support prudential arguments for long-distance leisure trips made by frequent flyers. (shrink)

In this article I hold that utilitarians are wrong to want to disaggregate climate- induced harm, whether in terms of chaotic or linear causality. This is not because individual emissions do not count, in probabilistic terms, for risk projections of overall climate dam- age, rather because individual emissions only contribute to increasing atmospheric CO2 concentration if the anthropogenic flow of CO2 exceeds the amount of CO2 that can be naturally taken up by the biosphere, over a given time segment. I (...) therefore maintain that individual climate duties consist of reforming the social and technological structures that make each individual emission part of a collective phenomenon, global warming, which leads to an enormous global disutility, climate change. In the final part of the article, I ar- gue that utilitarian ethics would have much more to say if, instead of focusing on the dis- aggregation of climate-induced harm, it addressed the key issues of the energy transition, i.e. carbon pricing, research and development in green technologies and climate finance.

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)

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)

Over the last decade, climate neutrality has emerged as an empowering, new concept—and it has given rise to concerns that it may be conducive to greenwashing and a disregard for justice and sustainability. Are these concerns justified? This paper argues that there is a qualified case for climate neutrality as part of an integrated approach to climate ethics. There are ethical and economic arguments for climate neutrality. An ethical conception of climate neutrality puts critical emphasis on reduction as well as (...) transparent measurement, substitution and stakeholder involvement so as to counter a prevailing focus on compensation.

Although actions of individuals do contribute to climate change, the question whether or not they, too, are morally obligated to reduce the GHG emissions in their responsibility has not yet been addressed sufficiently. First, I discuss prominent objections to such a duty. I argue that whether individuals ought to reduce their emissions depends on whether or not they exceed their fair share of emission rights. In a next step I discuss several proposals for establishing fair shares and also take practical (...) considerations into account. I conclude that individuals should not always be obliged to reduce their emissions to what is their fair share for they may depend on carbon-intensive structures. Instead, they have a Kantian imperfect duty to reduce their emissions ‘as far as can reasonably be demanded of them’. In addition, they should press governments to introduce proper regulation. At the end, I further specify both duties. (shrink)

Discussions of harm are central in the climate ethics literature. Especially in the rapidly emerging body of work addressing the question of whether or not individuals are morally responsible for their greenhouse gas (GHG) emissions, whether or in what way individuals’ emissions are harmful is a hotly debated question. John Nolt’s recent paper, “How harmful are the average American’s greenhouse gas emissions?” illustrates the prevalence of this framing (Nolt 2011). Here I take a step back and ask what we mean (...) by the concept “harmful” when talking about climate change. I argue, as several respondents to Nolt have suggested (e.g., Attfield 2011, Odenbaugh 2011), that we should not be so quick to apply our standard .. (shrink)

There is a difference between acting with a probability of making a difference to who is harmed, and worsening someone’s prospect. This difference is relevant to debates about the ethics of offsetting, since it means that showing that emitting-and-offsetting has the first feature is not a way of showing that it has the second feature. In an earlier paper, we illustrate this difference with an example of a lottery in which you shake the bag from which a ball will be (...) drawn to determine the identity of the person who will suffer a harm. Here, we reply to Stefansson and Willners’ criticism of that example, explaining how their reply makes a mistake about the point of the example. (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.

In this paper I examine the relation between Social Cost of Carbon (SCC) estimates, abatement cost analyses, and individual climate duties. I first highlight the stakes that SCC and abatement cost estimates potentially have for the content of individual duties to either pay the full or fair cost of their carbon emissions, or offset the volume of their emissions. I survey four methodological options (a minimalist approach, a precautionary approach, an averaging approach, and what I call a ‘sufficiency-bounded’ precautionary approach) (...) for conceptualizing the terrain of individual duties in light of SCC and abatement cost estimates that are both contentious and evolving.

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)

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 rapidly expanding literature on the ethics of climate engineering, a lot has been made of the fact that stratospheric aerosol injection would for the first time create a world whose climate had been intentionally shaped by deliberate human decisions. Intention has always mattered in ethics. Due to the importance of intention in assigning culpability for harms, one might expect that the moral responsibility for any harms created during an attempt to reconstruct the global climate using stratospheric aerosols would (...) be considerable. This article investigates such an expectation by making a comparison between the culpability for any unintended harms resulting from stratospheric aerosol injection and culpability for the unintended harms already taking place due to carbon emissions. To make this comparison, both types of unintended harms are viewed through the lens of the doctrine of double effect. The conclusion reached goes against what many might expect. The article closes by suggesting that a good way to read this surprising conclusion is that it points toward the continuing moral importance of prioritizing emission reductions. (shrink)

Environmental philosophies concerning our obligations to each other and the natural world too rarely address the aftermath of environmental injustice.
