The prominent burden-sharing principles in the emerging literature of the political theory of climate change fail to sufficiently tackle the task they set out to solve. This paper sets out properties that an alternative principle should aim to meet. Based on these properties, it develops a consequentialist moral principle – the wastefulness principle. This principle holds that it is wrong to waste a shared, scarce resource. The paper argues that this principle can be used to solve the question of who (...) should bear the burdens of anthropogenic climate change in a more suitable way than existing principles. After developing the wastefulness principle, this paper discusses in a non-exhaustive manner how it can be employed in the real world, which challenges it might meet, and how additional principles might solve them.

This article contributes to recent work on justice in resilience-based projects for climate adaptation. At present, the model commonly used for guiding normative reflection in this domain is the tripartite model of justice, whereby justice is seen as comprising distributive, procedural and recognitional aspects. After discussing some conceptual problems and practical shortcomings of this model, we propose an alternative model with six forms of justice or kinds of justice demands: distributive, procedural, intergenerational, restorative and retributive justice, and justice in system (...) outcomes. We also illustrate some advantages of this model with respect to representative accounts of the tripartite model. (shrink)

This paper is concerned with the moral concept of harm in the context of the Warsaw International Mechanism for Loss and Damage. This paper delineates between two concepts of wrongful harm: interactional versus architectural. It then examines these options with an eye toward developing a satisfactory normative approach for policy. While the interactional view of wrongful harm supports powerful arguments about moral responsibility, it has some clear limitations. This paper makes a case for the architectural view by underlining that it (...) is not only compatible with the features of the Paris Agreement but also supports a distinctive conception of justice.

Since 2011, the focus of international negotiations under the UNFCCC has been on producing a new climate agreement to be adopted in 2015. This phase of negotiations is known as the Durban Platform for Enhanced Action. The goal has been to update the global effort on climate for long-term cooperation. In this period, various changes have been contemplated on the design of the architecture of the global climate effort. Whereas previously, the negotiation process consisted of setting mandated targets exclusively for (...) developed countries, the current setting requests of each country to pledge its contribution to the climate effort in the form of Intended Nationally Determined Contributions. The shift away from establishing negotiated targets for rich countries alone towards a universal system of participation through intended contributions raised persistent questions on how exactly the new agreement can ensure equitable terms. How to conceptualize equity within the 2015 climate agreement, and beyond, is the focus of this paper. The paper advances a framework on equity, which moves away from substantive moral conceptions of burden allocation toward refining principles of public reason specially designed for the negotiation process under the UNFCCC. The paper outlines the framework’s main features and discusses how it can serve a facilitating role for multilateral discussion on equity on a long-term basis capable of adapting to changing circumstances.

Until recently, climate scientists were unable to link the occurrence of extreme weather events to anthropogenic climate change. In recent years, however, climate science has made considerable advancements, making it possible to assess the influence of anthropogenic climate change on single weather events. Using a new technique called ‘probabilistic event attribution’, scientists are able to assess whether anthropogenic climate change has changed the likelihood of the occurrence of a recorded extreme weather event. These advancements raise the expectation that this branch (...) of climate science can contribute to climate adaptation efforts. This paper examines the normative underpinnings of these policy discussions. To date, the debates revolve around whether the findings of attribution science can be used to establish moral liability for harms resulting from climate change. On close analysis, this normative framework has serious shortcomings. The paper rejects the moral liability framework and suggests, through a review of the international climate negotiations under the UNFCCC, that the science of event attribution can inform adaptation policy within a risk-pooling and climate risk insurance framework. The proposed framework is defended both on normative grounds and on the basis of its potential application within the Warsaw International Mechanism for Loss and Damage under the Cancun Adaptation Framework.

The urgent importance of dealing with the climate crisis has led some influential theorists to argue that at least some demands for justice must give way to pragmatic and strategic considerations. These theorists (Cass Sunstein, Eric Posner, and David Weisbach, all academic lawyers, and John Broome, an academic philosopher) contend that the failures of international negotiations and other efforts to change economic policies and practices have shown that moral exhortations are worse than ineffective. Although Broome's position is similar in these (...) respects to that of Sunstein, Posner and Weisbach, it differs in other important respects, including his understanding of the idea of justice, his disagreement with the policy approach (which he calls "efficiency with sacrifice") favored by the economists Nicholas Stern and William Nordhaus, and his proposal for establishing a new international financial institution, a World Climate Bank, in addition to putting a price on carbon. Elsewhere I offer a critical analysis of the position taken by Posner and Weisbach in their book, Climate Change Justice. Their arguments against allowing principles of distributive justice (narrowly understood) to constrain treaty negotiations fail to rule out the principles of John Rawls' Law of Peoples (which is a conception of the moral basis of a just international order, including states' obligations to secure basic human rights for all). Therefore their arguments against shaping climate treaties to reflect any principles of justice do not succeed in supporting their position. Here I offer a critical analysis of Broome's position. I raise and discuss objections to Broome's proposal for a WCB, and I argue that the continued relevance of these objections is contingent on how the proposal for a WCB may get developed. (shrink)

Obstacles to achieving a global climate treaty include disagreements about questions of justice raised by the UNFCCC's principle that countries should respond to climate change by taking cooperative action "in accordance with their common but differentiated responsibilities and respective capabilities and their social and economic conditions". Aiming to circumvent such disagreements, Climate Change Justice authors Eric Posner and David Weisbach argue against shaping treaty proposals according to requirements of either distributive or corrective justice. The USA's climate envoy, Todd Stern, takes (...) a similar position. In this article I explain the practical and theoretical drawbacks of Posner & Weisbach's welfarist perspective and propose an alternative. I show that their arguments fail to rule out John Rawls' non-utilitarian, political conception of international justice and human rights, the Law of Peoples. On this basis I develop a conception of climate justice that highlights implications of some of Rawls' principles and adds a principle for determining fair shares of climate -treaty-related benefits and burdens. I propose this conception as a moral framework for negotiating a treaty that would promote human welfare consistently with requirements of justice, and I argue that a treaty proposal satisfying these requirements could best satisfy Posner & Weisbach's own feasibility criteria.

There is a growing need to implement anticipatory climate change adaptation measures, particularly in vulnerable sectors, such as in agriculture. However, setting goals to adapt is wrought with several challenges. This paper discusses two sets of challenges to goals of anticipatory adaptation, of empirical and normative character. The first set of challenges concern issues such as the extent to which the climate will change, the local impacts of such changes, and available adaptive responses. In the second set of uncertainties are (...) issues such as the distribution of burdens to enhance adaptive capacities in vulnerable agents with a legitimate claim to such resources, and what anticipatory adaptation ideally should result in. While previous discussions have been limited to either discuss the first or second set of uncertainties, this paper suggests that both dimensions should be considered when setting goals in social planning with long time frames. A taxonomy will be suggested that combines both dimensions. Furthermore, strategies for managing situations in which there are either empirical, or normative, uncertainties will be proposed which could be used in social decision-making with long planning time-frames in which goals must be set.

Environmental philosophies concerning our obligations to each other and the natural world too rarely address the aftermath of environmental injustice. Ideally we would never do each other wrong; given that we do, as fallible and imperfect agents, we require non-ideal ethical guidance. Margaret Walker’s work on moral repair and Annette Baier’s work on cross-generational communality together provide useful hermeneutical tools for understanding and enacting meaningful responses to intergenerational injustice, and in particular, for anthropogenic climate change. By blending Baier’s cross-generational approach (...) with Walker’s emphasis on victim subjectivity and moral repair, I propose that a reparative model of intergenerational justice can provide some much needed direction on non-ideal moral issues comparatively neglected in climate-ethics debates today.

Action must be taken to combat climate change. Yet, how the costs of climate action should be allocated among states remains a question. One popular answer—the polluter-pays principle (PPP)—stipulates that those responsible for causing the problem should pay to address it. While intuitively plausible, the PPP has been subjected to withering criticism in recent years. It is timely, following the Paris Agreement, to develop a new version: one that does not focus on historical production-based emissions but rather allocates climate burdens (...) in proportion to each state’s annual consumption-based emissions. This change in carbon accounting results in a fairer and more environmentally effective principle for distributing climate duties. (shrink)

Written both for general readers and college students, Dialogues on Climate Justice provides an engaging philosophical introduction to climate justice, and should be of interest to anyone wanting to think seriously about the climate crisis. -/- The story follows the life and conversations of Hope, a fictional protagonist whose life is shaped by a terrifyingly real problem: climate change. From the election of Donald Trump in 2016 until the 2060s, the book documents Hope’s discussions with a diverse cast of characters. (...) As she ages, her conversations move from establishing the nature of the problem, to engaging with climate skepticism, to exploring her own climate responsibilities, through managing contentious international negotiations, to considering big technological fixes, and finally, as an older woman, to reflecting with her granddaughter on what one generation owes another. Following a philosophical tradition established by Plato more than two thousand years ago, these dialogues are not only philosophically substantive and carefully argued, but also distinctly human. The differing perspectives on display mirror those involved in real-world climate dialogues going on today. (shrink)

This paper discusses two approaches to climate ethics for practicalreflection and decision-making in concrete local climate changegovernance. After a brief review of the main conceptual frameworksin climate ethics research, we show that none of these leadingapproaches is sufficiently context specific and pluralistic to provideguidance appropriate for concrete local climate governance. Asalternatives, we present principlism as a methodology of midlevelprinciples and environmental pragmatism as an ethicalapproach. We argue that the two methodologies of principlismand pragmatism offer a new pluralistic framework that allows (...) realworldconditions and contexts to be properly integrated into ethicalanalysis and decision-making in climate governance.

Human beings are the cause of many current environmental problems. This poses the question of how to respond to these problems at the national and international level. However, many people ask themselves whether they should personally contribute to solving these problems and how they could (best) do so. This is the focus of this Special Issue on Individual Environmental Responsibility. The introduction proposes a way to structure this complex debate by distinguishing three broad clusters of arguments. The first cluster tackles (...) the kind of ethical theory we need to properly address different aspects of individual responsibility. The second cluster asks what individuals should do from an ethical point of view. The third cluster investigates the role of contextual factors and the limits of demandingness in individual obligations. This introduction presents the papers of the Special Issue and the interrelations between them using those clusters of arguments as reference. (shrink)

The relationship between knowledge, belief, and ethics is an inaugural theme in philosophy; more recently, under the title “ethics of belief” philosophers have worked to develop the appropriate methodology for studying the nexus of epistemology, ethics, and psychology. The title “ethics of belief” comes from a 19th-century paper written by British philosopher and mathematician W.K. Clifford. Clifford argues that we are morally responsible for our beliefs because each belief that we form creates the cognitive circumstances for related beliefs to follow, (...) and we inevitably influence each other through those beliefs. This study argues that recent cognitive research supports Cliffordian insights regarding patterns of belief formation and social influence. From the confirmation offered by such research, it follows that informational accuracy holds serious ethical significance in public discourse. Although scientific and epistemological matters are not always thought to be linked to normative morality, this study builds on Clifford's initial insights to show their linkage is fundamental to inquiry itself. In turn, Clifford's ethical and epistemic outline can inform a framework grounded in “public reason” under which seemingly opposed science communication strategies are philosophically united. With public discourse on climate change as the key example, empirically informed and grounded strategies for science communication in the public sphere are considered. (shrink)

The importance and urgency of using ethical principles in the creation and content of climate change policy is well recognised. This article closely examines the World Conservation Union’s (IUCN) engagement in ethical elements of international climate policy for abatement. The primary finding is the use of narrow framing around ‘nature based solutions’. The IUCNs’ own policy references to ethical principles such as fairness and justice are not adequately applied to the content of policy or to its critique. Recommendations are made (...) on how the IUCN (and NGOs generally) could enhance its ethical engagement to act consistently with the claim of moral leadership. (shrink)

Both intertemporal and intratemporal equity are central to the examination of policy towards climate change. However, many discussions of intertemporal issues have been marred by serious analytical errors, particularly in applying standard approaches to discounting; the errors arise, in part, from paying insufficient attention to the magnitude of potential damages, and in part from overlooking problems with market information. Some of the philosophical concepts and principles of Paper 1 are applied to the analytics and ethics of pure-time discounting and infinite-horizon (...) models, providing helpful insights into orderings of welfare streams and obligations towards future generations. Such principles give little support for the idea of discrimination by date of birth. Intratemporal issues are central to problematic and slow-moving international discussions and are the second focus of this paper. A way forward is to cast the policy issues and analyses in a way that keeps equity issues central and embeds them in the challenge of fostering the dynamic transition to the low-carbon economy in both developed and developing countries. This avoids the trap of seeing issues primarily in terms of burden-sharing and zero-sum games – that leads to inaction and the most inequitable outcome of all. (shrink)

In this article, we claim that recent developments in climate science and renewable energy should prompt a reframing of debates surrounding climate change mitigation. Taken together, we argue that these developments suggest (1) global climate collapse in this century is a non-negligible risk, (2) mitigation offers substantial benefits to current generations, and (3) mitigation by some can generate social tipping dynamics that could ultimately make renewables cheaper than fossil fuels. We explain how these claims undermine familiar framings of climate change, (...) wherein mitigation is understood as self-sacrifice that individuals and governments must be morally persuaded or incentivized to undertake.

This paper uses a novel account of non-ideal political action that can justify radical responses to severe climate injustice, including and especially deliberate attempts to engineer the climate system in order reflect sunlight into space and cooling the planet. In particular, it discusses the question of what those suffering from climate injustice may do in order to secure their fundamental rights and interests in the face of severe climate change impacts. Using the example of risky geoengineering strategies such as sulfate (...) aerosol injections, I argue that peoples that are innocently subject to severely negative climate change impacts may have a special permission to engage in large-scale yet risky climate interventions to prevent them. Furthermore, this can be true even if those interventions wrongly harm innocent people. (shrink)

Many academics and world leaders have declared that there is a moral imperative to address climate change. But such claims often fall on deaf ears because the nature of the threat posed by global warming lacks many of the features of a paradigmatic moral transgression [Jamieson, Dale. 2007. The moral and political challenges of climate change. Working Paper, New York University, New York]. This paper explores these psychological obstacles to moral engagement about climate change. I argue that the temporal and (...) psychosocial distance of the threat of global warming undermines the kind of affective response that motivates moral concern. I conclude by suggesting that images focusing more on the personal and short-term consequences of global warming will generate stronger moral reactions. (shrink)

The paper argues against the assumption that citizens of industrialized countries bear responsibility for greenhouse emissions in the nineteenth and early twentieth centuries. An array of arguments for such a historic responsibility is refuted. The crucial role of the assumption of a liability for bona fide misappropriation in a state of nature (Lockean strict liability) is pointed out.

This paper focuses on one particular case that connects climate justice and climate economics. Its contribution is twofold. First, it aims at providing a sound normative foundation for carbon pricing mechanisms around the notions of a ‘right to energy’, the ‘duty not-to-harm’ and an argument for ‘restricted compensation’. Second, it identifies the normative elements from theories of climate justice that should guide the design of market-based instruments for climate change mitigation. This will cast light on the particular moral relevance of (...) the act of internalizing a negative externality and of the funds generated by putting a price on carbon. (shrink)

Critics of carbon mitigation often appeal to what Jonathan Glover has called ‘the argument from no difference’: that is, ‘If I don’t do it, someone else will’. Yet even if this justifies continued high emissions by the industrialised countries, it cannot excuse business as usual. The North’s emissions might not harm the victims of climate change in the sense of making them worse off than they would otherwise be. Nevertheless, it receives benefits produced at the latter’s expense, with the result (...) that it has more than it deserves, and that victims will have less. This enrichment is unjust; unjustly enriched agents ought to make compensation. The best form of compensation is vigorous action against climate change. (shrink)

A range of developing countries and international advocacy organizations have argued that wealthy countries, as a result of their greater historical contribution to human-induced climate change, owe a ?climate debt? to poor countries. Critics of this argument have claimed that it is incoherent or morally objectionable. In this essay we clarify the concept of climate debt and assess its value for conceptualizing responsibilities associated with global climate change and for guiding international climate negotiations. We conclude that the idea of a (...) climate debt can be coherently formulated, and that while some understandings of the idea of climate debt could lead to morally objectionable conclusions, other accounts would not. However, we argue that climate debt nevertheless provides an unhelpful frame for advancing global justice through international climate negotiations ? the only existing means of resolving political conflict over the collective action problems posed by human-induced climate change ? due to its retrospective and potentially adversarial emphasis, and to problems of measurement.

At the United Nations climate change conference in 2011, parties decided to launch the “Durban Platform” to work towards a new long-term climate agreement. The decision was notable for the absence of any reference to “equity”, a prominent principle in all previous major climate agreements. Wealthy countries resisted the inclusion of equity on the grounds that the term had become too closely yoked to developing countries’ favored conception of equity. This conception, according to wealthy countries, exempts developing countries from making (...) commitments that are stringent enough for the collective effort needed to avoid dangerous climate change. In circumstances where even mentioning the term equity has become problematic, a critical question is whether scope for a fair agreement is being squeezed out of negotiations. To address this question we set out a conceptual framework for normative theorizing about fairness in international negotiations, accompanied by a set of minimal standards of fairness and plausible feasibility constraints for sharing the global climate change mitigation effort. We argue that a fair and feasible agreement may be reached by (i) reforming the current binary approach to differentiating developed and developing country groups, in tandem with (ii) introducing a more principled approach to differentiating the mitigation commitments of individual countries. These two priorities may provide the basis for a principled bargain between developed and developing countries that safeguards the opportunity to avoid dangerous climate change without sacrificing widely acceptable conceptions of equity.

In the debate on climate change commentators often express pessimistic or optimistic views. We see this mainly in the media and popular literature, but also in various academic fields. The aim of this paper is to investigate different kinds of pessimistic and optimistic views put forward in this debate and suggest explanations of the diversity of views. The paper concludes that pessimism and optimism may concern, for example, climate change as an unmitigated or poorly mitigated process, mitigation of climate change (...) or specific measures of mitigation. These aspects are important to distinguish, because a person can be pessimist concerning climate change as an unmitigated or poorly mitigated process and optimist concerning mitigation of climate change, and be pessimist concerning one specific mitigation measure and optimist concerning another. It is suggested that the diversity of pessimistic and optimistic views is due to the uncertainty of scientific climate models and the influence of evaluative and ideological assumptions. (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)

Purpose The purpose of this paper is to pinpoint and analyse ethical issues raised by the dual role of artificial intelligence in relation to climate change, that is, AI as a contributor to climate change and AI as a contributor to fighting climate change. Design/methodology/approach This paper consists of three main parts. The first part provides a short background on AI and climate change respectively, followed by a presentation of empirical findings on the contribution of AI to climate change. The (...) second part presents proposals by various AI researchers and commentators on how AI companies may contribute to fighting climate change by reducing greenhouse gas emissions from training and use of AI and by providing AI assistance to various mitigation and adaptation measures. The final part investigates ethical issues raised by some of the options presented in the second part. Findings AI applications may lead to substantial emissions but may also play an important role in mitigation and adaptation. Given this dual role of AI, ethical considerations by AI companies and governments are of vital importance. Practical implications This paper pinpoints practical ethical issues that AI companies and governments should take into account. Social implications Given the potential impact of AI on society, it is vital that AI companies and governments take seriously the ethical issues raised by the dual role of AI in relation to climate change. Originality/value AI has been the subject of substantial ethical investigation, and even more so has climate change. However, the relationship between AI and climate change has received only limited attention from an ethical perspective. This paper provides such considerations. (shrink)

One major question in climate justice is whether developed countries’ historical emissions are relevant to distributing the burdens of mitigating climate change. To argue that developed countries should bear a greater share of the burdens of mitigation because of their past emissions is to advocate ‘historical accountability.’ Standard arguments for historical accountability rely on corrective justice. These arguments face important objections. By using the notion of a global emissions budget, however, we can reframe the debate over historical accountability in terms (...) of distributive justice. This paper argues that, given two defensible assumptions, distributive justice requires historical accountability. These assumptions are that the proper claimants on the emissions budgets are societies or states, not individuals, and that we should be allocating the entirety of the original, pre-industrial budget, rather than just the remainder.

Anthropogenic climate change is a global process affecting the lives and well-being of millions of people now and countless number of people in the future. For humans, the consequences may include significant threats to food security globally and regionally, increased risks of from food-borne and water-borne as well as vector-borne diseases, increased displacement of people due migrations, increased risks of violent conflicts, slowed economic growth and poverty eradication, and the creation of new poverty traps. Principles of justice are statements of (...) what persons are owed either by others or by institutions and policies. Climate change gives rise to many concern of justice. This article briefly summarizes some of the most important of these, including claims to have climate change mitigated, claims regarding the sharing of the costs of climate change mitigation, claims for investment into adaptation, and claims to be compensated.

RESUMOA climatologia está no centro de um dos debates mais polarizados da atualidade, apresentado como confronto entre os defensores da existência de um aquecimento global antropogênico e aqueles que rejeitam sua existência. A instituição chave para esse tema é o Painel Intergovernamental sobre Mudanças Climáticas, um corpo simultaneamente científico e político. O debate surge aí mesclado com a discussão política sobre as respostas adequadas ao aquecimento global. Mas, rechaçados nesse terreno, os negacionistas transpõem o debate para a mídia, onde mobilizam (...) a pseudociência para deslegitimar as conclusões das disciplinas científicas ligadas ao entendimento do clima. Temos, assim, uma produção consciente da ignorância em larga escala sobre o tema do aquecimento global, demandando o uso da agnotologia para desvendar o mecanismo de produção da ignorância. A climatologia revela-se, então, um campo exemplar para o estudo da inserção histórico-social do conhecimento científico e das tensões e trajetórias conflitivas no seu interior, dos dilemas éticos que coloca e das possibilidades universalistas do conhecimento científico na era da tecnociência. ABSTRACTClimatology is at the center of one of the most polarized debates of today. It is presented as a confrontation between supporters of the existence of anthropogenic global warming and those who deny its existence. The key institution for this theme is the Intergovernmental Panel on Climate Change, which is both a scientific and political body. In this context, the debate arises merged with the political discussion on appropriate responses to global warming. However, contested on this ground, the deniers transfer the debate to the media, mobilizing pseudo-science to delegitimize the conclusions of the scientific disciplines related to climate understanding. Therefore, we have a deliberate production of large-scale ignorance on this subject, which requires the use of agnotology to unravel it. Thus, climatology reveals itself an exemplary space to study the historical and social roots of scientific knowledge and the tensions and conflicting trajectories inside it, the ethical dilemmas posed and the universalist possibilities of scientific knowledge in the age of technoscience.

This paper argues that extortion is a clear threat in intergenerational relations, and that the threat is manifest in some existing proposals in climate policy and latent in some background tendencies in mainstream moral and political philosophy. The paper also claims that although some central aspects of the concern about extortion might be pursued in terms of the entitlements of future generations, this approach is likely to be incomplete. In particular, intergenerational extortion raises issues about the appropriate limits to the (...) sway of central values such as welfare and distributive justice. We should be wary of ways in which such values invite us to buy off, or perhaps to join, an intergenerational climate Mafia. (shrink)

ABSTRACT In Debating Climate Ethics, David Weisbach and I offer contrasting views of the importance of ethics and justice for climate policy. I argue that ethics is central. Weisbach advocates for climate policy based purely on narrow forms of self-interest. For this symposium, I summarize the major themes, and extend my basic argument. I claim that ethics gets the problem right, whereas dismissing ethics risks getting the problem dangerously wrong, and perpetuating profound injustices. One consequence is that we should reject (...) the alleged “feasibility constraint” of short-term, economic self-interest. (shrink)

Climate change presents us with a problem of intergenerational justice. While any costs associated with climate change mitigation measures will have to be borne by the world’s present generation, the main beneficiaries of mitigation measures will be future generations. This raises the question to what extent present generations have a responsibility to shoulder these costs. One influential approach for addressing this question is to appeal to neo-classical economic cost–benefit analyses and so-called economy-climate “integrated assessment models” to determine what course of (...) action a principle of intergenerational welfare maximization would require of us. I critically examine a range of problems for this approach. First, integrated assessment models face a problem of underdetermination and induction: They are very sensitive to a number of highly conjectural assumptions about economic responses to a temperature and climate regime, for which we have no empirical evidence. Second, they involve several simplifying assumptions which cannot be justified empirically. And third, some of the assumptions underlying the construction of economic models are intrinsically normative assumptions that reflect value judgments of the modeler. I conclude that, while integrated assessment models may play a useful role as “toy models,” their use as tools for policy optimization is highly problematic. (shrink)

This chapter lays out what we take to be the main types of justice and ethical challenges concerning those adverse effects of climate change leading to climate-related Loss and Damage (L&D). We argue that it is essential to clearly differentiate between the challenges concerning mitigation and adaptation and those ethical issues exclusively relevant for L&D in order to address the ethical aspects pertaining to L&D in international climate policy. First, we show that depending on how mitigation and adaptation are distinguished (...) from L&D, the primary focus of policy measures and their ethical implications will vary. Second, we distinguish between a distributive justice framework and a compensatory justice scheme for delivering L&D measures. Third, in order to understand the differentiated remedial responsibilities concerning L&D, we categorise the measures and policy approaches available. Fourth, depending on the kind of L&D and which remedies are possible, we explain the difference between remedial and outcome responsibilities of different actors. [Open access]. (shrink)

In discussions about responsibility for climate change, it is often suggested that the historical use of natural resources is in some way relevant to our current attempts to address this problem fairly. In particular, both theorists and actors in the public realm have argued that historical high-emitters of greenhouse gases (GHGs) – or the beneficiaries of those emissions – are in possession of some form of debt, deriving from their overuse of a natural resource that should have been shared more (...) equitably. These accounts of what might be termed ‘natural debt’ generally focus on one particular natural resource (global GHG sink capacity); invoke a principle of justice by which rights to consume this resource should have been allocated (most commonly, equal per capita shares); and then argue that historical violations of this principle give rise to certain rectificatory duties in the present (generally, duties on the part of those who have historically consumed an excessive amount of the world’s GHG sink capacity, or who have benefitted from such excess consumption, to offer some form of compensation to those who have not – such compensation usually taking the form of emission credits or cash). Though many seem to find it intuitively plausible that historical high-emissions have incurred some form of debt, significant challenges arise in rendering the concept of natural debt both coherent and defensible. Such problems are not, however, my focus in this piece. Instead, I here suggest that discussions about historical responsibility for climate change commonly fail to recognise certain other past injustices concerning natural resources that appear to hold contemporary relevance. In particular, I argue that it is not just the unequal consumption of global GHG sink capacity that may be of moral significance here; but also the way in which the world’s resources have more generally been governed.

Emissions grandfathering maintains that prior emissions increase future emission entitlements. The view forms a large part of actual emission control frameworks, but is routinely dismissed by political theorists and applied philosophers as evidently unjust. A sympathetic theoretical reconsideration of grandfathering suggests that the most plausible version is moderate, allowing that other considerations should influence emission entitlements, and be justified on instrumental grounds. The most promising instrumental justification defends moderate grandfathering on the basis that one extra unit of emission entitlements from (...) a baseline of zero emissions increases welfare to a greater extent where it is assigned to a high emitter than where it is assigned to a low emitter. Moderate grandfathering can be combined with basic needs and ability to pay considerations to provide an attractive approach to allocating emission entitlements. (shrink)

Is authoritarian power ever legitimate? The contemporary political theory literature—which largely conceptualizes legitimacy in terms of democracy or basic rights—would seem to suggest not. I argue, however, that there exists another, overlooked aspect of legitimacy concerning a government’s ability to ensure safety and security. While, under normal conditions, maintaining democracy and rights is typically compatible with guaranteeing safety, in emergency situations, conflicts between these two aspects of legitimacy can and often do arise. A salient example of this is the COVID-19 (...) pandemic, during which severe limitations on free movement and association have become legitimate techniques of government. Climate change poses an even graver threat to public safety. Consequently, I argue, legitimacy may require a similarly authoritarian approach. While unsettling, this suggests the political importance of climate action. For if we wish to avoid legitimating authoritarian power, we must act to prevent crises from arising that can only be resolved by such means. (shrink)
