This paper focuses on a specific proposal connected with the issue of mitigating climate change by reducing GHG concentrations in the atmosphere. The idea of campaigning in favour of a temporary reproductive suspension, to be addressed to a range of citizens of developed countries , is explored. Some details of the proposal are specified, and the proposal itself is defended against four objec- tions: 1. that it encroaches reproductive freedom; 2. that it subtracts from the overall value (...) the value of future lives; 3. that it is costly and ineffectual; 4. that it is unfair, especially when women are considered.

The climate change mitigation effort is being translated into several actions and discourses that make collateral benefits and their rationale increasingly relevant for sustainability, in such a way that they are now a constant part of the political agenda. Taking a broader and consensual perspective, co-benefits are considered here to be emerging advantages of implementing measures to lower greenhouse gases. Starting with the analysis of policy documents referring to two European urban transportation strategies, the emergent co-benefits are problematized (...) and discussed to better understand their moral aspect. Further ethical reflection is conducted after an analysis of some unintended consequences of the co-benefits rationale arising from the examples. The discussion focuses primarily on the challenges of an integrative moral justification for co-benefits and also for their role in the climate change mitigation effort. We also discuss the limitations of the current normative models that frame a co-benefits rationale, both from a moral viewpoint and in relation to the overall climate change mitigation strategy. In this article, we propose the concepts of well-being and freedom, as portrayed by the Capability Approach, as possible guiding notions for the moral and social evaluation of goodness of these emergent benefits as well as their rationale. Additionally, some preliminary conclusions are drawn regarding the potential of the presented concepts to support climate change mitigation action. Finally, we outline a scenario where the Capability Approach is the moral guideline for a co-benefits rationale and illustrates its potential in terms of enhancing climate change mitigation strategy.

Formal arguments have proven that avoiding the Repugnant Conclusion is impossible without rejecting one or more highly plausible population principles. To many, such proofs establish not only a deep challenge for axiology, but also pose an important practical problem of how policymaking can confidently proceed without resolving any of the central questions of population ethics. Here we offer deflationary responses: first to the practical challenge, and then to the more fundamental challenge for axiology. Regarding the practical challenge, (...) we provide an overview of recent literature that explores the implications for public policy of the Repugnant Conclusion and related puzzles within population ethics, and shows that there is more commonality in the implications of different population axiologies than is generally recognized. The upshot is that uncertainty about population ethics presents no important problem for policymaking, and the importance of population ethics to policymaking has been overstated. We then turn to more fundamental issues about axiology, and describe a new series of formal proofs that undermine the idea that any plausible axiology could avoid the Repugnant Conclusion, including those that are assumed to avoid it in the literature. The philosophical upshot is that the Repugnant Conclusion cannot plausibly be avoided, and so it is a mistake to assume as a constraint on a plausible axiology that it must be avoided, as is assumed by most of the literature in population ethics, including by all of the fundamental impossibility theorems.

What are the prospects for using population policy as tool to reduce carbon emissions? In this paper, we review evidence from population science, in order to inform debates in population ethics that, so far, have largely taken place within the academic philosophy literature. In particular, we ask whether fertility policy is likely to have a large effect on carbon emissions, and therefore on temperature change. Our answer is no. Prospects for a policy of fertility-reduction-as-climate-mitigation are (...) limited by population momentum, a demographic factor that limits possible variation in the size of the population, even if fertility rates change very quickly. In particular, a hypothetical policy that instantaneously changed fertility and mortality rates to replacement levels would nevertheless result in a population of over 9 billion people in 2060. We use a leading climate-economy model to project the consequence of such a hypothetical policy for climate change. As a standalone mitigation policy, such a hypothetical change in the size of the future population-much too large to be implementable by any foreseeable government programme-would reduce peak temperature change only to 6.4°C, relative to 7.1°C under the most likely population path. Therefore, fertility reduction is unlikely to be an adequate core approach to climate mitigation. (shrink)

Future population growth is uncertain and matters for climate policy: higher growth entails more emissions and means more people will be vulnerable to climate-related impacts. We show that how future population is valued importantly determines mitigation decisions. Using the Dynamic Integrated Climate-Economy model, we explore two approaches to valuing population: a discounted version of total utilitarianism (TU), which considers total wellbeing and is standard in social cost of carbon dioxide (SCC) models, and of (...) average utilitarianism (AU), which ignores population size and sums only each time period’s discounted average wellbeing. Under both approaches, as population increases the SCC increases, but optimal peak temperature decreases. The effect is larger under TU, because it responds to the fact that a larger population means climate change hurts more people: for example, in 2025, assuming the United Nations (UN)-high rather than UN-low population scenario entails an increase in the SCC of 85% under TU vs. 5% under AU. The difference in the SCC between the two population scenarios under TU is comparable to commonly debated decisions regarding time discounting. Additionally, we estimate the avoided mitigation costs implied by plausible reductions in population growth, finding that large near-term savings ($billions annually) occur under TU; savings under AU emerge in the more distant future. These savings are larger than spending shortfalls for human development policies that may lower fertility. Finally, we show that whether lowering population growth entails overall improvements in wellbeing—rather than merely cost savings—again depends on the ethical approach to valuing population.

Population ethics is the subfield of philosophy that focuses on the moral aspects of how actions affect who exists in a particular population and what quality of life they have. The choices regarding what policies are adopted in response to climate change will affect the identities of those who exist in the future, the size of future populations, and the quality of life that future people will have. This chapter examines the nonidentity problem, various theoretical outlooks on (...) population ethics, some recent policy proposals aimed at reducing fertility, and the relationship between population reduction and the impacts of climate change. After summarizing the relevant issues, the relevance of the discourse to climate policy is highlighted, and points of consensus and dissensus are noted. Disagreement on some of the key theoretical questions in population ethics is significant and poses a challenge for deriving meaningful conclusions about climate policy. Fortunately, emerging points of consensus on other aspects of climate policy and its relationship to population provide reasons to think moral decision-making about these matters is far from hopeless.

This article explores the main similarities and differences between Derek Parfit’s notion of imprecise comparability and a related notion I have proposed of parity. I argue that the main difference between imprecise comparability and parity can be understood by reference to ‘the standard view’. The standard view claims that 1) differences between cardinally ranked items can always be measured by a scale of units of the relevant value, and 2) all rankings proceed in terms of the trichotomy of ‘better than’, (...) ‘worse than’, and ‘equally good’. Imprecise comparability, which can be understood in terms of the more familiar notions of cardinality and incommensurability, rejects only the first claim while parity rejects both claims of the standard view. -/- I then argue that insofar as those attracted to imprecise comparability assume that all rankings are trichotomous, as Parfit appears to, the view should be rejected. This is because imprecise equality is not a form of equality but is a sui generis ‘fourth’ basic way in which items can be ranked. We should, I argue, understand imprecise equality as parity, and imprecise comparability as entailing ‘tetrachotomy’ – that if two items are comparable, one must better than, worse than, equal to, or on a par with the other. Thus those attracted to the idea that cardinality can be imprecise should abandon trichotomy and accept parity and tetrachotomy instead. -/- Finally, I illustrate the difference between Parfit’s trichotomous notion of imprecise comparability and parity by examining how each notion might be employed in different solutions to the problem posed by the Repugnant Conclusion in population ethics. I suggest that parity provides the arguably more ecumenical solution to the problem. (shrink)

It has been argued that the most impactful choice an individual could make, with respect to mitigating greenhouse gas emissions, is to have fewer children. This paper brings up a related aspect of individuals’ reproductive choices that has been neglected in the climate ethics literature: the timing aspect. It is argued that, from a climate change perspective, it does not matter only how many children people bring into existence, but also when they are brought into existence. The (...) reason is that the age at which parents choose to procreate affects the number of people that will live simultaneously on the planet, which is in turn relevant for climate change. This provides individuals another means by which they can decrease their emissions. (shrink)

Climate change poses a serious problem for established ethical theories. There is no dearth of literature on the subject of climate ethics that break down the complexity of the issue, thereby enabling one to arrive at partial conclusions such as: 'historical justice demands us to do this...' or 'intergenerational justice demands us to do that...'. In contrast, this article attempts to face up to this complexity, that is: to end with a synthesis of the arguments into what can (...) be considered to be the most reasonable and fairest approach to the politics of climate change on a global scale. A significant part of the paper is devoted to the questions whether or not a) historical emissions and b) population changes are relevant to how emissions rights should be distributed. I discuss the merits and drawbacks of each perspective and briefly outline the normative justifications. (shrink)

This chapter qualitatively lays out some of the ways that climate change impacts are evaluated in integrated assessment models (IAMs). Putting aside the physical representations of these models, it first discusses some key social or structural assumptions, such as the damage functions and the way growth is modeled. Second, it turns to the moral assumptions, including parameters associated with intertemporal evaluation and interpersonal inequality aversion, but also assumptions in population ethics about how different-sized populations are compared and how (...) we think about distributing goods across or within times. The intention is to survey the morally important assumptions that go into estimates of the social cost of carbon, the marginal cost of an additional tonne of carbon dioxide to society. (shrink)

This book examines the link between population growth and environmental impact and explores the implications of this connection for the ethics of procreation. In light of climate change, species extinctions, and other looming environmental crises, Trevor Hedberg argues that we have a collective moral duty to halt population growth to prevent environmental harms from escalating. This book assesses a variety of policies that could help us meet this moral duty, confronts the conflict between protecting the welfare of (...) future people and upholding procreative freedom, evaluates the ethical dimensions of individual procreative decisions, and sketches the implications of population growth for issues like abortion and immigration. It is not a book of tidy solutions: Hedberg highlights some scenarios where nothing we can do will enable us to avoid treating some people unjustly. In such scenarios, the overall objective is to determine which of our available options will minimize the injustice that occurs. This book will be of great interest to those studying environmental ethics, environmental policy, climate change, sustainability, and population policy. (shrink)

Climate change is imposing intensified and novel selection pressures on organisms by altering abiotic and biotic environmental conditions on Earth, but studies demonstrating genetic adaptation to climate change mediated selection are still scarce. Evidence is accumulating to indicate that both genetic and ecological constrains may often limit populations' abilities to adapt to large scale effects of climate warming. These constraints may predispose many organisms to respond to climate change with range shifts and phenotypic plasticity, rather than (...) through evolutionary adaptation. In general, broad conclusions about the role of evolutionary adaptation in mitigating climate change induced fitness loss in the wild are as yet difficult to make.Editor's suggested further reading in BioEssays: How will fish that evolved at constant sub‐zero temperatures cope with global warming?

There is a growing movement advocating for using closed border policies as a tool for solving the climate crisis. On this view, which I call the green border argument, fighting climate change requires drastic reductions in the global population and/or per capita greenhouse gas (GHG) emissions. However, immigration into high-income countries—particularly from low-income countries—increases per capita emissions while leaving the population untouched. Therefore, the green border theorist argues, we should limit entry into high-income countries. I explain (...) why this is a mistake and why the political left should embrace a pro climate and pro migrant politic. -/- First, the argument significantly overstates the impact of immigration on global GHG emissions. Second, the progressive green border argument is normatively incoherent. It advocates for closing borders and eliminating poverty and other rights violations in sending countries. However, given the relationship between emissions and income, this argument would require rejecting all poverty reduction strategies—a conclusion the progressive theorist wants to avoid. Third, the argument is counterproductive. An open border politic better promotes climate justice. A key reason is that high-income countries perceive immigration to be one of the most serious short- and medium- term costs of climate change. Whereas closure allows them to avoid this “cost,” open borders would force them to eliminate push factors, incentivizing global adaptation and mitigation strategies. Moreover, a closed border politic creates divisions between those affected, undermining cross-border solidarity and contributing to the perception that environmentalism is a white, middle-class movement.

According to the Intergovernmental Panel on Climate Change, human population growth is one of the two primary causes of increased greenhouse gas emissions and accelerating global climate change. Slowing or ending population growth could be a cost effective, environmentally advantageous means to mitigate climate change, providing important benefits to both human and natural communities. Yet population policy has attracted relatively little attention from ethicists, policy analysts, or policy makers dealing with this issue. In part, (...) this is because addressing population matters means wading into a host of contentious ethical issues, including family planning, abortion, and immigration. This article reviews the scientific literature regarding voluntary population control's potential contribution to climate change mitigation. It considers possible reasons for the failure of climate ethicists, analysts, and policy makers to adequately assess that contribution or implement policies that take advantage of it, with particular reference to the resistance to accepting limits to growth. It explores some of the ethical issues at stake, considering arguments for and against noncoercive population control and asking whether coercive population policies are ever morally justified. It also argues that three consensus positions in the climate ethics literature regarding acceptable levels of risk, unacceptable harms, and a putative right to economic development, necessarily imply support for voluntary population control.

This paper focuses on the relations between population ethics and metaethics. Population ethics gives rise to well-known paradoxes, such as the paradox of mere addition. After presenting a version of this paradox, it is argued that a different way to dismantle it might be by considering it as a way to change our standard view of justification in moral theory. Two possible views are considered: a non-cognitivist approach to justification and to the explanation of inconsistency in morals; Parfit's (...) suggestion that certain paradoxes might be «quarantined» without shaking our confidence in moral theories encapsulating them.

Climate change poses real and immediate impacts to the public health of populations around the globe. Adverse impacts are expected to continue throughout the century. Emphasizing co-benefits of climate action for health, combining adaptation and mitigation efforts, and increasing interagency coordination can effectively address both public health and climate change challenges.

Travis Rieder's Toward a Small Family Ethic confronts the effects of population growth and addresses what individual procreative obligations might follow from it. In this review, I summarize the main arguments that Rieder deploys to defend his position that those with large ecological footprints morally ought to follow a small family ethic. I express sympathy with some of his claims and praise the book's accessibility, but its short length inevitably means that some important issues are omitted or given only (...) superficial treatment. I highlight a few of those issues at the end of the review. (shrink)

Despite the substantial research into the peculiar political and legal status of climate migrants, there is comparatively little exploration of the particular forms of loss such migrants might face or how efforts might mitigate such loss. This paper aims to begin filling that void by characterizing such loss, using the framework of the UNFCC’s Warsaw Mechanism, as agential harm. Using existing models for thinking about the preservation of values and links with the past, I aim to use this idea (...) of a threat to agency to discuss how migration could occur to better preserve the agential control of displaced populations.

In 2020, COVID-19, the Australia bushfires, and other global threats served as vivid reminders that human and nonhuman fates are increasingly linked. Human use of nonhuman animals contributes to pandemics, climate change, and other global threats which, in turn, contribute to biodiversity loss, ecosystem collapse, and nonhuman suffering. Jeff Sebo argues that humans have a moral responsibility to include animals in global health and environmental policy. In particular, we should reduce our use of animals as part of our pandemic (...) and climate change mitigation efforts and increase our support for animals as part of our adaptation efforts. Applying and extending frameworks such as One Health and the Green New Deal, Sebo calls for reducing support for factory farming, deforestation, and the wildlife trade; increasing support for humane, healthful, and sustainable alternatives; and considering human and nonhuman needs holistically. Sebo also considers connections with practical issues such as education, employment, social services, and infrastructure, as well as with theoretical issues such as well-being, moral status, political status, and population ethics. In all cases, he shows that these issues are both important and complex, and that we should neither underestimate our responsibilities because of our limitations, nor underestimate our limitations because of our responsibilities. Both an urgent call to action and a survey of what ethical and effective action requires, Saving Animals, Saving Ourselves is an invaluable resource for scholars, advocates, policy-makers, and anyone interested in what kind of world we should attempt to build and how.

The ‘Lima Call for Climate Action’ decision marked the conclusion of the 20th session of the Conference of Parties to the United Nations Framework Convention on Climate Change. It expresses how the 196 UNFCCC Parties intend to negotiate the elements of a new agreement to be opened for signature in Paris at COP21. This ‘Paris Agreement’ would govern Parties starting in 2020, when the Kyoto Protocol's second commitment period ends. The new agreement would also move Parties beyond the (...)

Adults in the United States are having fewer biological children in part due to worries about climate change and population growth, yet Christian environmental ethicists frequently avoid or dismiss these “eco-reproductive” concerns. I argue that these avoidances lead to important limitations in the literature, which I address by employing a pragmatic approach for religious ethics. Learning from environmentalists who are critically engaging with their Christian inheritances, I find that informants draw upon religious repertoires to “kinnovate.” Namely, they (...) expand notions of family beyond biological lineage by taking up vocations as godparents, youth mentors, foster parents, or chosen kin. I claim that these practices of Christian kinnovation are significant because they help to advance creative moral responses to eco-reproductive concerns in religious contexts—interventions that currently remain underdeveloped in relevant ethical and theological literatures.

The population ethics literature has long focused on attempts to avoid the repugnant conclusion. We show that a large set of social orderings that are conventionally understood to escape the repugnant conclusion do not in fact avoid it in all instances. As we demonstrate, prior results depend on formal definitions of the repugnant conclusion that exclude some repugnant cases, for reasons inessential to any "repugnance" (or other meaningful normative properties) of the repugnant conclusion. In (...) particular, the literature traditionally formalizes the repugnant conclusion to exclude cases that include an unaffected sub-population. We relax this normatively irrelevant exclusion, and others. Using several more inclusive formalizations of the repugnant conclusion, we then prove that any plausible social ordering implies some instance of the repugnant conclusion. This understanding-that it is impossible to avoid all instances of the repugnant conclusion-is broader than the traditional understanding in the literature that the repugnant conclusion can only be escaped at unappealing theoretical costs. Therefore, the repugnant conclusion provides no methodological guidance for theory or policy-making, because it does not discriminate among candidate social orderings. So escaping the repugnant conclusion should not be a core goal of the population ethics literature. (shrink)

Climate change policy decisions are inescapably intertwined with future generations. Even if all carbon dioxide emissions were to be stopped today, most aspects of climate change would persist for hundreds of years, thus inevitably raising questions of intergenerational justice and sustainability. -/- The chapter begins with a short overview of discount rate debate in climate economics, followed by the observation that discounting implicitly makes the assumption that natural capital is always substitutable with man-made capital. The chapter explains (...) why non-substitutability matters if we are to take intergenerational justice seriously and invest aptly in mitigation. Non-substitutability simply implies that there are some forms of capital that cannot be substituted by another, and so consumption of one cannot be compensated with additional stocks of the other. The non-substitutability of critical natural capital can be defended without empirical data about preferences or the need to view the environment as a superior good, and the argument is presented through the language of keeping options open. -/- Those alive today make decisions about what natural capital to use and what to save for future. These choices are often represented as different points in a continuum of sustainability: weak sustainability is associated with a high degree of substitutability and therefore a lot of flexibility over what capital to consume, whereas strong sustainability is more stringent on substitutability. While it may be that in economical understanding weak and strong sustainability collapse into one another, philosophically the emphasis is slightly different. The chapter discusses how normative sustainability can be supported without ignoring opportunity costs and trade-offs. (shrink)

Climate ethics and environmental ethics sometimes provide conflicting action guidance. For instance, favored climate policies to avoid global mean increases beyond 1.5-2 °C may have detrimental effects on biodiversity by requiring transforming environmental areas into croplands for bioenergy and for negative emission technologies. From this follows a potential moral conflict between the demands of climate ethics, according to which transforming natural ecosystems to cropland for bioenergy is permissible and perhaps even obligatory if it reduces risks of (...) class='Hi'>climate change, and the demands of environmental ethics, according to which transforming natural ecosystems into croplands is prohibited if it reduces biodiversity, assuming that biodiversity, or its components, have moral standing. Consequently, there is a choice: either preserve biodiversity, but accept higher risks of dangerous climate change; or reduce the risks of dangerous climate change with the aid of negative emission technologies but increase biodiversity deterioration. In this paper I investigate other options like lower population growth and relying on technological efficiency; I conclude that neither will ultimately be consistent with both climate and environmental ethics. I argue that both climate and environmental ethics can support limiting the consumption of energy while mitigating emissions of greenhouse gases and preserving biodiversity, hence resolving the conflicting moral recommendations. I further suggest that virtues such as humility and simplicity can accommodate just such an expansion of moral concern and provide environmental ethical guidance in climate policies. (shrink)

This paper examines structural barriers to the adoption of climate change mitigation practices and the evolution of a climate change ethic among American farmers. It examines how seed corn contracts in Michigan constrain the choices of farmers and allow farmers to rationalize the over-application of fertilizer and associated water pollution and greenhouse gas emissions. Seed corn contracts use a competitive “tournament” system where farmers are rewarded for maximizing yields. Interviews and a focus group were used to understand (...) fertilizer over-application and barriers to participating in a climate change mitigation program. Results indicate that farmers agree that they over-apply fertilizer but would be unlikely to participate in a mitigation program due to their contracts and lack of support from seed corn companies. Because only a few companies control access to the seed corn market, farmers feel they have few choices. Farmers rationalized their practices as their only option given the competitive nature of their contracts and blamed other sources of pollution. Despite increasing efforts to educate farmers about climate change, structural barriers will continue to constrain participation in mitigation efforts and the development of a climate change ethic.

ObjectivePhysical and mental well-being are threatened by climate change. Since hospitals in high-income countries contribute significantly to climate change through their greenhouse gas (GHG) emissions, the medical ethics imperative of ‘do no harm’ imposes a responsibility on hospitals to decarbonise. We investigated hospital stakeholders’ perceptions of hospitals’ GHG emissions sources and the sense of responsibility for reducing GHG emissions in a hospital.MethodsWe conducted 29 semistructured qualitative expert interviews at one of Germany’s largest hospitals, Heidelberg University Hospital. Five patients, (...) 12 clinical and 12 administrative employees on different levels were selected using purposive maximum variation sampling. Interviews were transcribed verbatim and analysed using the framework approach.ResultsConcerning GHG emissions, hospital stakeholders perceived energy and waste as most relevant emission sources followed by mobility. Climate change mitigation in general was considered as important. However, in their role as patients or employees, hospital stakeholders felt less responsible for climate change mitigation. They saw providing best possible medical care to be the top priority in hospitals and were often concerned that patients’ health could be jeopardised by climate change mitigation measures.ConclusionPerceptions of most important emission sources did not coincide with those in literature, highlighting the need to inform stakeholders, for instance, about pharmaceuticals as important emission source. A frequently perceived conflict between reducing emissions and providing high-quality medical care could be eased, if reducing emissions would not only be justified as a contribution to mitigation, but also as a contribution to preventing ill health—a basic principle of medical ethics.

It is often claimed that reducing population size would be advantageous for climate change mitigation, on the grounds that lower population would naturally correspond to lower emissions. This apparently obvious claim is in fact seriously misleading. Reducing population size would indeed, other suitable things being equal, reduce the emissions rate. But it is well recognised that the primary determinant of the eventual amount of climate change is not the emissions rate, but rather cumulative emissions. (...) It is far less clear whether reducing population size would reduce cumulative emissions, or would in any other way prove an advantage for reasons related to climate change. This paper identifies and briefly discusses the issues relevant to assessing that less clear question. (shrink)

As a subspecies of the climate justice debate, a compelling moral case can be made that actors should receive their fair share of benefits and burdens, and more specifically, that those who benefit from the provision of public goods ought, under some circumstances, to share in the costs of their provision. The climate justice debate has paid relatively scant attention, however, to the possible adverse side-effects of climate mitigation mechanisms. The article reviews such global public goods-protecting (...) techniques as compensation payments for keeping rainforests intact, and climate engineering, for their adverse impact on human rights and biodiversity. Espousing a consequentialist ethical perspective, it calls for increased vigilance in institutionally designing and implementing climate change mitigation mechanisms, however well-intentioned these may be.

Climate change confronts us with our most pressing challenges today. The global consensus is clear that human activity is mostly to blame for its harmful effects, but there is disagreement about what should be done. While no shortage of proposals from ecological footprints and the polluter pays principle to adaptation technology and economic reforms, each offers a solution – but is climate change a problem we can solve? In this provocative new book, these popular proposals for ending or (...) overcoming the threat of climate change are shown to offer no easy escape and each rest on an important mistake. Thom Brooks argues that a future environmental catastrophe is an event we can only delay or endure, but not avoid. This raises new ethical questions about how we should think about climate change. How should we reconceive sustainability without a status quo? Why is action more urgent and necessary than previously thought? What can we do to motivate and inspire hope? Many have misunderstood the kind of problem that climate change presents – as well as the daunting challenges we must face and overcome. Climate Change Ethics for an Endangered World is a critical guide on how we can better understand the fragile world around us before it is too late. This innovative book will be of great interest to students and scholars of climate change, climate justice, environmental policy and environmental ethics. "This book offers a rare combination of tough-mindedness, analytic rigor, and passion as it tackles the greatest challenge of our time―climate change. For Brooks, it’s past time to acknowledge that climate change cannot be solved though the careful selection of good polices. Climate change is an unavoidable tragedy that we must endure but may be able to survive. Offering a program that emphasizes flexibility and adaptation, Brooks brings original insights to a debate that too long has been bogged down in wishful thinking and empty scholasticism."

The repugnant conclusion can be formulated as follows: For any population consisting of people with very high positive welfare, there is a better population in which everyone has a very low positive welfare, other things being equal. As the name indicates, this conclusion appears unacceptable. Yet it has proven to be surprisingly difficult to find a theory that avoids it without implying other very counterintuitive conclusions. Moreover, the conclusion is a problem not just for total utilitarians or (...) those committed to welfarism but for all moral theories according to which welfare matters at least when all other things are equal, which arguably is a minimal adequacy condition for any moral theory. And, not the least, how to deal with it has implications for the present generations’ duties to future generations and intergenerational justice. The question as to how the repugnant conclusion should be dealt with has thus become one of the cardinal challenges of modern ethics, and the inquiry into what it shows about the nature of ethics has opened up many new avenues for research. This chapter covers the different suggestions in the literature on how to do deal with the conclusion, both on the axiological and on the normative levels. Moreover, the conclusion and different ways of deriving it are explained in detail. (shrink)

We are in the midst of a crisis of climate change and environmental degradation that will only get worse, unless significant changes are rapidly made. Globally, the healthcare sector causes a large share of our total environmental footprint: 4.4% of greenhouse gases. Sustainable healthcare has emerged as a way for healthcare sectors in high‐income countries to help mitigate climate change by reducing their emissions. Whether global health should be sustainable and what ethical grounds might exist to support such (...) a claim are not questions that have been investigated. The paper argues that global health practice—the delivery of health services to underserved populations in resource‐poor areas of the world—should be sustainable as a matter of climate justice and solidarity. Reducing climate change‐related risks and harms for the vulnerable is integral to the mission of global health and thus it is necessary to consider the climate impact of its practice. The field has a duty to provide sustainable health services that are responsive to climate change‐related changes in the local burden of disease and to build sustainable health system infrastructure. Specific responsibilities for global health funders, managers, and implementers to uphold the duty are proposed. To conclude, the paper considers what limits might be placed on the duty to deliver sustainable global healthcare. (shrink)

Treaty Norms and Climate Change MitigationDarrel MoellendorfCurrently the international community is discussing the regulatory framework to replace the Kyoto Protocol after 2012. The unveiling of the new framework is scheduled to occur at the December 2009 COP in Copenhagen. The stakes are high, since any treaty will affect the development prospects of per capita poor countries and will determine the climate change–related costs borne by poor people for centuries to come. Failure to arrive at an agreement would have (...) grave effects on the development prospects of poor countries, many of which will experience the most severe effects of climate change. The original UNFCCC treaty recognizes these kinds of concerns and requires that further treaty negotiation pay them heed. Any agreement will be required to conform to UNFCCC norms related to sustainable development and the equitable distribution of responsibilities. In this paper I argue that UNFCCC norms tightly constrain the range of acceptable agreements for the distribution of burdens to mitigate climate change. I conclude that any legitimate treaty must put much heavier mitigation burdens on industrialized developed countries. Of the various proposals that have received international attention, two in particular stand out as possibly satisfying UNFCCC norms regarding the distribution of responsibilities. (shrink)

The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research. We believe, however, that the Repugnant Conclusion now receives too much focus. Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.

In this article we address the so-called argument of «individual causal inefficacy» (ICI), according to which CO2-emission-generating actions are morally neutral with regards to climate change, in so far as, taken in their singularity, they are neither sufficient nor necessary to cause climate change. In the first part, we address the main substantive objection to ICI: if a single emission, analysed in isolation, does not cause any disutility, it is impossible to explain why climate change (which is (...) the result of a sum of emissions) is the source of an enormous disutility; thus, ICI should be rejected in so far as it leads to a conclusion that is logically inconsistent. We argue, contrary to this, that it is possible to hold together ICI and individual moral responsibility for climate change, given the characteristics of the natural carbon cycle and of net-zero emissions. In the second part, accordingly, we propose a theory of individual responsibility for climate change which is based on the distinction between individual and collective freedom to emit, compatibly with a given mitigation target. This theory allows us to maintain that there exists a moral duty to reduce individual emissions, without having to demonstrate the fallacy of ICI. This duty is based on distributive reasons, which can prescind from the direct causal relationship between individual polluting actions and climate damage. (shrink)

According to Critical-Level Views in population axiology, an extra life improves a population only if that life’s welfare exceeds some fixed ‘critical level.’ An extra life at the critical level leaves the new population equally good as the original. According to Critical-Range Views, an extra life improves a population only if that life’s welfare exceeds some fixed ‘critical range.’ An extra life within the critical range leaves the new population incommensurable with the original. -/- In (...) this paper, I sharpen some old objections to these views and offer some new ones. Critical-Level Views cannot avoid certain Repugnant and Sadistic Conclusions. Critical-Range Views imply that lives featuring no good or bad components whatsoever can nevertheless swallow up and neutralise goodness or badness. Both classes of view entail that certain small changes in welfare correspond to worryingly large differences in contributive value. -/- I then offer a view that retains much of the appeal of Critical-Level and Critical-Range Views while avoiding the above pitfalls. On the Imprecise Exchange Rates View, the quantity of some good required to outweigh a given unit of some bad is imprecise. This imprecision is the source of incommensurability between lives and populations. (shrink)

The primary responsibility for global climate change responsiveness is usually attributed to nation states. This is reflected in the United Nations’ processes aimed at enrolling governments in mitigation and adaptation programmes. Such an approach begs the question of how global climate change (GCC) responsiveness might proceed if a national government is hostile to the issue, as appears likely to be the case in the USA. This paper addresses this concern by documenting the percentage of the population (...) of the USA who are ‘covered’ by at least one of six examples of GCC responsiveness at sub-federal – state and municipality – levels. Of the population of the USA, 25.8% lives in states where all of the state-level initiatives surveyed are in effect, whereas only 4.4% are not covered by any of the six. This coverage has increased as compared to earlier surveys (Lutsey, N., and D. Sperling. 2008. “America’s Bottom-Up Climate Change Mitigation Policy.” Energy Policy 36: 673–685. doi:10.1016/j.enpol.2007.10.018). This finding suggests that there is more practical hope for GCC responsiveness than might be commonly appreciated and this also has ramifications for research in accounting. (shrink)

Analysing the demands of global justice for the distribution of resources is a complex task and requires consideration of a broad range of issues. Of particular relevance is the effect that different distributions will have on global population growth and individual welfare. Since changes in the consumption and distribution of resources can have major effects on the welfare of the global population, and the rate at which it increases, it is important to establish meaningful principles to ensure a (...) just distribution of resources. In order to establish such principles we must consider the scope of any reproductive rights, and rights to other goods, such as food and health care, as well as examine the extent of duties correlating to those rights. In addition to the impact that distributions of global goods have on the welfare of current generations, it is also important to consider what duties we have, if any, to future generations. -/- The final version of this paper is available to download here: http://dx.doi.org/10.1002/9780470015902.a0024140.

Climate change is considered one of the most pressing problems for life on Earth. Climate engineering technologies, it is believed, can offer a potential response to climate change and effective solutions to deal with its effects. However, these technologies may also pose risks. This chapter explores the ethical issues raised by climate engineering. It is divided into two parts. The first part asks what the ethical constraints of the technology might be and how moral responsibility in (...) climate engineering technologies might be articulated. The second part explores the role that artificial intelligence (AI) in information and communication technologies (ICTs) could play in relation to climate change and mitigation and adaptation measures.

Totalism states that one population is better than another iff it has higher total welfare. One counterintuitive consequence is the Repugnant Conclusion (RC). Totalism also entails that a very large population of animals with lives barely worth living is better than a smaller population of happier humans. Furthermore, the strategies that have been used to avoid the troubling normative implications of the RC do not work in the animal case, so we may have reason to bring (...) about such a population. I introduce the notion of ‘Efficiency of Welfare Production’ – that animals of different species vary in the efficiency with which they convert resources into welfare. If we want to maximize total welfare, without any speciesist bias, we should identify which species is most efficient and try to maximize the population of that species. This has counterintuitive implications whether we accept hedonism or a more sophisticated theory of welfare. (shrink)

In this paper I discuss ethical issues related to mitigation of climate change. In particular, I focus on mitigation of climate change to the extent this change is caused by livestock production. I support the view—on which many different ethical approaches converge—that the present generation has a moral obligation to mitigate climate change for the benefit of future generations and that developed countries should take the lead in the process. Moreover, I argue that since livestock (...) production is an important contributing factor to climate change, we should undertake mitigation measures also in this sector and not only in, for example, the transport and energy sectors. However, technological solutions do not seem sufficient in the livestock sector, leaving us with the option of reduced meat production and consumption. In order to reach significant results in mitigation of climate change, political steering seems necessary. With this in mind, I argue in favor of a tax on meat consumption. (shrink)

Urban residents have the potential to play a key role in helping to facilitate ecological resilience of wilderness areas and ecosystems beyond the city by helping ensure the migration of nonhuman climate refugee populations. Three ethical frameworks related to this issue could determine whether we have an ethical duty to help nonhuman climate refugee populations: ethical individualism, ethical holism, and species ethics. Using each of these frameworks could support the stronger view that policy makers and members of the (...) public have a moral duty to mitigate the impacts of climate induced migration, or the weaker claim that these impacts should be taken into account when making land-use and planning decisions in urban contexts.

Global climate change is one of the most daunting ethical and political challenges confronting humanity in the twenty-first century. The intergenerational and transnational ethical issues raised by climate change have been the focus of a significant body of scholarship. In this new collection of essays, leading scholars engage and respond to first-generation scholarship and argue for new ways of thinking about our ethical obligations to present and future generations. Topics addressed in these essays include moral accountability for energy (...) consumption and emissions, egalitarian and libertarian perspectives on mitigation, justice in relation to cap and trade schemes, the ethics of adaptation and the ethical dimensions of the impact of climate change on nature.

Given that mitigating climate change is a large-scale global issue, what obligations do individuals have to lower their personal carbon emissions? I survey recent suggestions by Walter Sinnott-Armstrong and Dale Jamieson and offer models for thinking about their respective approaches. I then present a third model based on the notion of structural violence. While the three models are not mutually incompatible, each one suggests a different focus for mitigating climate change. In the end, I agree with Sinnott-Armstrong that (...) people have limited moral obligations to directly lower personal emissions, but I offer different reasons for this conclusion, namely that the structural arrangements of our lives place a limit on how much individuals can restrict their own emissions. Thus, individuals should focus their efforts on changing the systems instead (e.g., the design of cities, laws and regulation, etc.), which will lead to lower emissions on a larger scale. (shrink)

In this paper we analyse and discuss the views of Swedish stakeholders on how to mitigate climate change to the extent it is caused by meat production. The stakeholders include meat producer organisations, governmental agencies with direct influence on meat production, political parties as well as non-governmental organisations. Representatives of twelve organisations were interviewed. Several organisations argued against the mitigation option of reducing beef production despite the higher greenhouse gas intensity of beef compared to pork and chicken meat (...) (according to life cycle analysis). Regarding feed production some organisations proposed use of the best available industrial fertilizers, others were against all use of such fertilizers. Several organizations suggested domestic production of more protein-rich fodder and use of manure for biogas production. Regarding meat consumption the focus was on throwing away less food as waste and on eating less meat but the best (most climate friendly) meat, which was considered to be Swedish meat in contrast to imported meat. There was agreement on many issues. Most disagreement was found regarding political steering. We find many of the stakeholders’ mitigation proposals regarding meat production and consumption acceptable. However, we are to some extent critical to their defence of Swedish beef production. We also point out certain problems with the suggestion to reduce consumption of imported meat but not of domestically produced meat. (shrink)
