Geoengineering is defined as the ‘deliberate and large-scale intervention in the Earth’s climatic system with the aim of reducing global warming’. The technological proposals for doing this are highly speculative. Research is at an early stage, but there is a strong consensus that technologies would, if realisable, have profound and surprising ramifications. Geoengineering would seem to be an archetype of technology as social experiment, blurring lines that separate research from deployment and scientific knowledge from technological artefacts. Looking into (...) the experimental systems of geoengineering, we can see the negotiation of what is known and unknown. The paper argues that, in renegotiating such systems, we can approach a new mode of governance—collective experimentation. This has important ramifications not just for how we imagine future geoengineering technologies, but also for how we govern geoengineering experiments currently under discussion. (shrink)

Because of the lack of a meaningful international response to global warming, geoengineering has emerged as a potential technological response to climate change. But, thus far, little attention has been given to how religion impacts our understanding of geoengineering. I defend the need to incorporate theological reflection in the conversation of geoengineering by investigating how geoengineering proposals contain an implicit anthropology. A significant framework for our assessment of geoengineering is the balance of human capability and (...) fallibility—a balance that is at the center of theological and religious interpretations of the meaning of the human condition. Similarly, geoengineering challenges our past understandings of theological anthropology. (shrink)

An old book by children’s author Dr. Seuss can be an inspiration to examine the ethical and ontological meaning of geoengineering. My argument is based on my critique of the process of ecological restoration as the creation of an artifactual reality. When humanity intentionally interferes with the processes and entities of nature, we change the ontological reality of the natural world. The world becomes a garden, or a zoo, an environment that must be continually managed to meet the goals (...) of human purposes. Geoengineering is a more radical and comprehensive example of this process of planetary management. Thus, as with ecological restoration, geoengineering reinforces the paradigm of human mastery and domination of nature. To counteract this dream of domination, we must, as Dr. Seuss instructed us when we were children, learn to live in the natural world with humility. (shrink)

As it becomes more and more doubtful that the international community will take adequate steps to mitigate climate change, interest has grown in the possibility of engineering earth’s climate to prevent catastrophic levels of warming. Unfortunately, geoengineering schemes have the potential to create grave, unintended consequences. This paper explores the extent to which the precautionary principle (PP), which was developed as a guideline for responding to uncertainty in the policy sphere, can provide guidance for responding to the potential benefits (...) and hazards associated with geoengineering. The paper argues that there are so many different versions of the precautionary principle and so many potential strategies for geoengineering that there cannot be any single, simple relationship between the two. Nevertheless, it is possible to identify a set of lessons that many versions of the PP suggest for those considering geoengineering proposals. Moreover, examination of the geoengineering case provides an opportunity to reflect on a range of important situations—what this paper will call self-defeating scenarios—in which most versions of the PP provide limited guidance compared to other ethical principles.

The strongest arguments for the permissibility of geoengineering (also known as climate engineering) rely implicitly on non-ideal theory—roughly, the theory of justice as applied to situations of partial compliance with principles of ideal justice. In an ideally just world, such arguments acknowledge, humanity should not deploy geoengineering; but in our imperfect world, society may need to complement mitigation and adaptation with geoengineering to reduce injustices associated with anthropogenic climate change. We interpret research proponents’ arguments as an application (...) of a particular branch of non-ideal theory known as “clinical theory.” Clinical theory aims to identify politically feasible institutions or policies that would address existing (or impending) injustice without violating certain kinds of moral permissibility constraints. We argue for three implications of clinical theory: First, conditional on falling costs and feasibility, clinical theory provides strong support for some geoengineering techniques that aim to remove carbon dioxide from the atmosphere. Second, if some kinds of carbon dioxide removal technologies are supported by clinical theory, then clinical theory further supports using those technologies to enable “overshoot” scenarios in which developing countries exceed the cumulative emissions caps that would apply in ideal circumstances. Third, because of tensions between political feasibility and moral permissibility, clinical theory provides only weak support for geoengineering techniques that aim to manage incoming solar radiation.

Against the background of continuing inadequacy in global efforts to address climate change and apparent social and political inertia, ever greater interest is being generated in the idea that geoengineering may offer some solution to this problem. I do not take a position, here, on whether or not geoengineering could ever be morally justifiable. My goal in this paper is more modest – but also has broader implications. I aim to show that even if some form of (...) class='Hi'>geoengineering might be ethically acceptable in certain specific circumstances, lab-based research into such techniques could nevertheless have morally problematic consequences. I support this claim by explaining that our current state of uncertainty regarding how the impacts of geoengineering interventions could be geographically distributed may help to promote international agreement on fair rules for the governance of geoengineering. In these circumstances of scientific uncertainty, international actors also face uncertainty regarding who the winners and losers could be with respect to potential rules of geoengineering governance, thereby obstructing the pursuit of self-interest in the selection of such rules. Instead of a research first approach, then, we have reason to take a governance first approach – ensuring that fair international institutions to regulate geoengineering activities are established before further research is conducted into how the costs and benefits of such interventions could be distributed.

Some scientists suggest that it might be possible to reflect a portion of incoming sunlight back into space to reduce climate change and its impacts. Others argue that such solar radiation management (SRM) geoengineering is inherently incompatible with democracy. In this article, we reject this incompatibility argument. First, we counterargue that technologies such as SRM lack innate political characteristics and predetermined social effects, and that democracy need not be deliberative to serve as a standard for governance. We then rebut (...) each of the argument’s core claims, countering that (1) democratic institutions are sufficiently resilient to manage SRM, (2) opting out of governance decisions is not a fundamental democratic right, (3) SRM may not require an undue degree of technocracy, and (4) its implementation may not concentrate power and promote authoritarianism. Although we reject the incompatibility argument, we do not argue that SRM is necessarily, or even likely to be, democratic in practice. (shrink)

Geoengineering; specifically Solar Radiation Management ; has been proposed to effect rapid influence over the Earth’s climate system in order to counteract Anthropogenic Global Warming. This poses near-term to long-term governance challenges; some of which are within the planning horizon of current political administrations. Previous discussions of governance of SRM have focused primarily on two scenarios: an isolated “Greenfinger” individual; or state; acting independently ; versus more consensual; internationalist approaches. I argue that these models represent a very limited sub-set (...) of plausible deployment scenarios. To generate a range of alternative models; I offer a short; relatively unstructured discussion of a range of different types of warfare – each with an analogous SRM deployment regime. (shrink)

There has been much discussion of the moral, legal and prudential implications of geoengineering, and of governance structures for both the research and deployment of such technologies. However, insufficient attention has been paid to how such measures might affect geoengineering in terms of the incentive structures which underwrite scientific progress. There is a tension between the features that make science productive, and the need to govern geoengineering research, which has thus far gone underappreciated. I emphasize how (...) class='Hi'>geoengineering research requires governance which reaches beyond science’s traditional boundaries, and moreover requires knowledge which itself reaches beyond what we traditionally expect scientists to know about. How we govern emerging technologies should be sensitive to the incentive structures which drive science. (shrink)

Stephen Gardiner argues that geoengineering does not meet the “canonical technical definition” of a global public good, and that it is misleading to frame geoengineering as a public good. A public good is something that is nonrival and nonexcludable. Contrary to Gardiner’s claims, geoengineering meets both of these criteria. Framing geoengineering as a public good is useful because it allows commentators to draw on the existing economic, philosophical, and social scientific literature on the governance of public (...) goods.

Many geoengineering projects have been proposed to address climate change, including both solar radiation management and carbon removal techniques. Some of these methods would introduce additional compounds into the atmosphere or the ocean. This poses a difficult conundrum: Is it permissible to remediate one pollutant by introducing a second pollutant into a system that has already been damaged, threatened, or altered? We frame this conundrum as the ‘‘Problem of Permissible Pollution.’’ In this paper, we explore this problem by taking (...) up ocean fertilization and advancing an argument that rests on three moral claims. We first observe that pollution is, in many respects, a context-dependent matter. This observation leads us to argue for a ‘‘justifiability criterion.’’ Second, we suggest that remediating actions must take into account the antecedent conditions that have given rise to their consideration. We call this second observation the ‘‘antecedent conditions criterion.’’ Finally, we observe that ocean fertilization, and other related geoengineering technologies, propose not strictly to clean up carbon emissions, but actually to move the universe to some future, unknown state. Given the introduced criteria, we impose a ‘‘future-state constraint’’. We conclude that ocean fertilization is not an acceptable solution for mitigating climate change. In attempting to shift the universe to a future state geoengineering sidelines consideration of the antecedent conditions that have given rise to it —conditions, we note, that in many cases involve unjustified carbon emissions —and it must appeal to an impossibly large set of affected parties.

If deployed, aerosol geoengineering (AG) could involve unfairness to both present and future parties. I discuss three broad risks of unfairness that an AG deployment policy might carry: (1) causing disproportionate harm to those least responsible for climate change, (2) burdening future parties with the costs and risks of AG, and (3) excluding some interested parties from contributing to AG decision-making. Yet despite these risks, it may be too hasty to reject AG deployment as a potential climate change policy. (...) I argue that since it is very unlikely that a completely fair climate change policy will be pursued, we have ethical reason to prefer some “incompletely fair” policy. Given various facts about our world, it might be the case that some AG policy is ethically preferable to many other feasible climate change policies, even if AG carries deeply problematic risks of unfairness.

Geoengineering – roughly “the intentional manipulation of the planetary systems at a global scale” (Keith 2000) – to combat climate change is often introduced as a “plan B”: an alternative solution in case “plan A”, reducing emissions, fails. This framing is typically deployed as part of an argument that research and development is necessary in case robust conventional mitigation is not forthcoming, or proves insufficient to prevent dangerous climate impacts. Since coming to prominence with the release of the Royal (...) Society report in 2009 (Shepherd et al. 2009, v), the Plan B framing has proved popular with scientists, in policy circles, and in the news media (see Nerlich and Jaspal 2012; Luokkanen, Huttunen, and Hilden 2014). Though sometimes used to refer to geoengineering as a whole, it is associated particularly strongly with stratospheric sulfate injection (SSI) techniques. Consequently, these will be our focus here. We argue that the plan B framing is particularly ill-suited to the integrative assessment of options within climate policy, because it oversimplifies a complex issue in a misleading and deceptive way. For instance, it highlights extreme positions, presents SSI as an alternative independent from mainstream policies, ignores the multiplicity of options available, and neglects threats of morally indecent SSI in a context of ongoing political inertia. We are particularly concerned about the way ‘Plan B’ risks conveying an implicit hyper-optimism about SSI, and so obscures the need for ethical standards. (shrink)

Global-scale solar geoengineering raises critical ethical questions, including questions of distributive, procedural, and intergenerational justice. Although geoengineering is sometimes framed as a response to injustice, insofar as it might benefit those most vulnerable to climate-related harms, geoengineering also has the potential to exacerbate climate injustice, especially if control of research, governance, and potential plans for deployment remains concentrated in the hands of a few. The scope and scale of solar geoengineering, the diverse concerns it raises, and (...) the lack of consensus surrounding it pose particular challenges for justice. I argue that addressing these challenges requires an inclusive, dialogical approach that takes seriously diverse perspectives, particularly the perspectives of those who are most affected by climate change and those who have had the least voice in decisions surrounding it. The concept of recognition––as developed in the work of Nancy Fraser, David Schlosberg, and others––offers a normative ground for this approach and can help guide the development of institutions and practices directed toward geoengineering justice.

Geoengineering is a technological response to anthropogenic climate change. There are two kinds of geoengineering: Solar Radiation Management (SRM) and Carbon Dioxide Removal (CDR). SRM aims at reducing the amount of incoming solar light and CDR at reducing the CO2 concentration in the atmosphere. Over the past decades, geoengineering has moved from a fringe proposal to a more mainstream contender along with mitigation and adaptation to avert climate change. However, it faces important ethical challenges.

According to the “Lesser of Two Evils Argument,” deployment of solar radiation management (SRM) geoengineering in a climate emergency would be morally justified because it likely would be the best option available. A prominent objection to this argument is that a climate emergency might constitute a genuine moral dilemma in which SRM would be impermissible even if it was the best option. However, while conceiving of a climate emergency as a moral dilemma accounts for some ethical concerns about SRM, (...) it requires the controversial claim that there are genuine moral dilemmas, and it potentially undermines moral action guidance in emergency scenarios. Instead, it is better to conceive of climate emergencies as situations calling for agent-regret. This alternative allows us coherently to hold that SRM may be morally problematic even if it ought to be deployed in some scenario. (shrink)

In early policy work, climate engineering is often described as a global public good. This paper argues that the paradigm example of geoengineering—stratospheric sulfate injection (hereafter ‘SSI’)—does not fit the canonical technical definition of a global public good, and that more relaxed versions are unhelpful. More importantly, it claims that, regardless of the technicalities, the public good framing is seriously misleading, in part because it arbitrarily marginalizes ethical concerns. Both points suggest that more clarity is needed about the aims (...) of geoengineering policy—and especially governance—and that this requires special attention to ethics. (shrink)

Ethics is highly relevant to grand technological interventions into basic planetary systems on a global scale (roughly, “geoengineering”). Focusing on climate engineering, this chapter identifies a large number of salient concerns (e.g., welfare, rights, justice, political legitimacy) but argues that early policy framings (e.g., emergency, global public good) often marginalize these and so avoid important questions of justification. It also suggests that, since it is widely held that geoengineering has become a serious option mainly because of political inertia, (...) there are important contextual issues, especially around the paradoxical question, “What should we do, ethically speaking, given that we have not done, and will continue not to do, what we should be doing?” Taking such issues seriously helps to explain why some regard geoengineering as ethically troubling and highlights the largely neglected threat of interventions that discriminate against future generations (“parochial geoengineering”). We should take seriously the risk that, far from being simply a welcome new tool for climate action, geoengineering may become yet another manifestation of the underlying problem. (shrink)

Some authors have called for increased research on various forms of geoengineering as a means to address global climate change. This paper focuses on the question of whether a particular form of geoengineering, namely deploying sulfate aerosols in the stratosphere to counteract some of the effects of increased greenhouse gas concentrations, would be a just response to climate change. In particular, we examine problems sulfate aerosol geoengineering (SAG) faces in meeting the requirements of distributive, intergenerational, and procedural (...) justice. We argue that SAG faces obstacles to meeting the requirements of all three considered kinds of justice, because its impacts can harm some persons and communities much more than others; it poses serious risks to future generations; and SAG is especially prone to unilateral implementation. While we do not claim that SAG ought not to be implemented, we argue that it is the responsibility of proponents of SAG to recognize and address these ethical obstacles before advocating its implementation.

ABSTRACT: There is general agreement amongst those involved in the normative discussion about geoengineering that if we are to move forward with significant research, development, and certainly any future deployment, legitimate governance is a must. However, while we agree that the abstract concept of legitimacy ought to guide geoengineering governance, agreement surrounding the appropriate conception of legitimacy has yet to emerge. Relying upon Allen Buchanan’s metacoordination view of institutional legitimacy, this paper puts forward a conception of legitimacy appropriate (...) for geoengineering governance, outlining five normative criteria an institution ought to fulfill if it is to justifiably coordinate our action around geoengineering.

Geoengineering as a technological intervention to avert the dangerous climate change has been on the table at least since 2006. The global outreach of the technology exercised in a non-encapsulated system, the concerns with unprecedented levels and scales of impact and the overarching interdisciplinarity of the project make the geoengineering debate ethically quite relevant and complex. This paper explores the ethical desirability of geoengineering from an overall review of the existing literature on the ethics of geoengineering. (...) It identifies the relevant literature on the ethics of geoengineering by employing a standard methodology. Based on various framing of the major ethical arguments and their subsets, the results section presents the opportunities and challenges at stake in geoengineering from an ethical point of view. The discussion section takes a keen interest in identifying the evolving dynamics of the debate, the grey areas of the debate, with underdeveloped arguments being brought to the foreground and in highlighting the arguments that are likely to emerge in the future as key contenders. It observes the semantic diversity and ethical ambiguity, the academic lop-sidedness of the debate, missing contextual setting, need for interdisciplinary approaches, public engagement, and region-specific assessment of ethical issues. Recommendations are made to provide a useful platform for the second generation of geoengineering ethicists to help advance the debate to more decisive domains with the required clarity and caution.

In response to the Royal Society report’s claim that “the acceptability of geo­engineering will be determined as much by social, legal, and political issues as by scientific and technical factors” (Geoengineering the Climate: Science, Governance and Uncertainty [London: Royal Society, 2009], ix), a number of authors have suggested the key to this challenge is to engage the public in geoengineering decision-making. In effect, some have argued that inclusion of the public in geoengineering decision-making is necessary for any (...) geoengineering project to be morally permissible. Yet, while public engagement on geoengineering comes in various forms, the discussion in geoengineering governance and the ethics of geoengineering have too often conceptualized it exclusively in terms of public participation in decision-making, and supported it by various liberal democratic values. However, if the predominant understanding of public engagement on—or, the role of the public in—geoengineering decision-making is indeed only grounded on liberal democratic values, then its normative relevance could be challenged by and in other ethical-political traditions that do not share those values. In this paper, I shall explore these questions from a Confucian perspective. I argue that the liberal democratic values invoked in support of the normative importance of public participation are, at least, foreign to Confucian political philosophy. This presents a prima facie challenge to view public participation in geoengineering decision-making as a universal moral requirement, and invites us to reconsider the normative significance of this form of public engagement in Confucian societies. Yet, I contend that the role of the public remains normatively significant in geoengineering governance and the ethics of geoengineering from a Confucian perspective. Drawing from recent work on Confucian political philosophy, I illustrate the potential normative foundation for public engagement on geoengineering decision-making. (shrink)

Researchers have explored questions concerning public participation and consent in geoengineering governance. Yet, the notion of consent has received little attention from researchers, and it is rarely discussed explicitly, despite being prescribed as a normative requirement for geoengineering research and being used in rejecting some geoengineering options. As it is noted in the leading geoengineering governance principles, i.e. the Oxford Principles, there are different conceptions of consent; the idea of consent ought to be unpacked more carefully (...) if, and when, we invoke it in the discussion. This article offers a theoretical reflection on different conceptions of consent and their place in geoengineering governance. More specifically, I discuss three models of consent, i.e. explicit consent, implied consent and hypothetical consent, and assess their applicability to geoengineering governance. Although there are different models of consent, much discussion of geoengineering governance has committed only to explicit consent. I note that such a commitment springs from a specific ideal political order. Accordingly, we should be wary of any naïve commitment to it so long as the political order we hope for remains open to debate. Finally, I illustrate two approaches to introduce consent into a geoengineering governance framework. (shrink)

Two questions are central to the ethics of geoengineering. The justificatory question asks ‘Under what future conditions might geoengineering become justified?’, where the conditions to be considered include, for example, the threat to be confronted, the background circumstances, the governance mechanisms, individual protections, compensation provisions, and so on. The contextual question asks ‘What is the ethical context of the push toward geoengineering, and what are its implications?’ Unfortunately, early discussions of geoengineering often marginalize both questions because (...) they tend to focus on arguments from emergency that illegitimately brush them aside. One sign of this is that some emergency arguments are ethically short-sighted, and morally schizophrenic. In this paper, I illustrate this problem by appeal to two abstract examples. Although both are extreme and idealized, even the imperfect analogies provide reasons for concern about our current predicament. Ethically serious discussion of geoengineering should confront such worries, rather than hide behind overly simplistic appeals to moral emergency. As Michael Stocker puts it in his seminal discussion of moral schizophrenia, “to refuse to do so bespeaks a malady of the spirit.” . (shrink)

In this paper, I address the question of whether aerosol geoengineering (AG) ought to be deployed as a response to climate change. First, I distinguish AG from emissions mitigation, adaptation, and other geoengineering strategies. Second, I discuss advantages and disadvantages of AG, including its potential to result in substantial harm to some persons. Third, I critique three arguments against AG deployment, suggesting reasons why these arguments should be rejected. Fourth, I consider an argument that, in scenarios in which (...) all available climate change strategies would result in net harm to persons, we ought to adopt that response to climate change which would result in the least net harm.

This paper aims to address the lack of critique of the linear model in geoengineering governance discourse, and to illustrate different considerations for a geoengineering governance framework that is not based on a linear model of technology innovation. Finally, we set to explore a particular approach to geoengineering governance based on Peter-Paul Verbeek’s notion of ‘technology accompaniment’.

Concerns about the risks of unmitigated greenhouse gas emissions are growing. At the same time, confidence that international policy agreements will succeed in considerably lowering anthropogenic greenhouse gas emissions is declining. Perhaps as a result, various geoengineering solutions are gaining attention and credibility as a way to manage climate change. Serious consideration is currently being given to proposals to cool the planet through solar-radiation management. Here we analyze how the unique and nontrivial risks of geoengineering strategies pose fundamental (...) questions at the interface between science and ethics. To illustrate the importance of integrated ethical and scientific analysis, we define key open questions and outline a coupled scientific-ethical research agenda to analyze solar-radiation management geoengineering proposals. We identify nine key fields of coupled research including whether solar-radiation management can be tested, how quickly learning could occur, normative decisions embedded in how different climate trajectories are valued, and justice issues regarding distribution of the harms and benefits of geoengineering. To ensure that ethical analyses are coupled with scientific analyses of this form of geoengineering, we advocate that funding agencies recognize the essential nature of this coupled research by establishing an Ethical, Legal, and Social Implications program for solar-radiation management.

Geoengineering has been broadly and helpfully defined as “the intentional manipulation of the earth's climate to counteract anthropogenic climate change or its warming effects” (Corner and Pidgeon , 26). Although there exists a rapidly growing literature on the ethics of geoengineering, very little has been written about its gender dimensions. The authors consider four contexts in which geoengineering appears to have important gender dimensions: (1) the demographics of those pushing the current agenda, (2) the overall vision of (...) control it involves, (3) the design of the particular technologies, and (4) whom geoengineering will most affect and benefit. After detailing these four gender dimensions, we consider three ways in which the geoengineering discourse could be enriched if it became more sensitive to issues of gender. These include increasing the focus on the concrete other, recognizing the socially transformative potential of geoengineering technologies, and engaging in value-sensitive design. Although ultimately remaining agnostic on the desirability of geoengineering, the paper brings gender considerations into a discussion from which they have been conspicuously absent. (shrink)

A collection of original and innovative essays that compare the justice issues raised by climate engineering to the justice issues raised by competing approaches to solving the climate problem.

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)

While geoengineering may counteract negative effects of anthropogenic climate change, it is clear that most geoengineering options could also have some harmful effects. Moreover, it is predicted that the benefits and harms of geoengineering will be distributed unevenly in different parts of the world and to future generations, which raises serious questions of justice. It has been suggested that a compensation scheme to redress geoengineering harms is needed for geoengineering to be ethically and politically acceptable. (...) Discussions of compensation for geoengineering harms, however, sometimes presume geoengineering has presented new and unique challenges to compensation that cannot be readily accommodated by existing compensation practices. The most explicit formulation of this view was recently presented by Toby Svoboda and Peter J. Irvine, who argued that two forms of uncertainty in geoengineering — namely, ethical uncertainty and scientific uncertainty — make it immensely difficult to devise an ethically and politically satisfactory compensation scheme for geoengineering harms. -/- In this paper, we argue against the view that geoengineering presents new and unique challenges relating to compensation. More specifically, we show that placing these challenges within the broader context of anthropogenic climate change reveals them to be less serious and less specific to geoengineering than some appear to believe.

Climate change poses grave risks to food security, and mitigation and adaptation actions have so far been insufficient to lessen the risk of climate-induced violations of the right to food. Could safeguarding the right to food, then, justify some forms of geoengineering? This article examines geoengineering through the analytical lens of the right to food. We look at the components of food security and consider how the acceptability of geoengineering relates to the right to food via its (...) impacts on these components. Our examination shows that results vary greatly between different forms of geoengineering: while some forms of geoengineering fail to respect the right to food, certain other forms may even become obligatory to protect the right to food. It appears that there is no support for aerosol-based solar radiation management, whereas some carbon dioxide removal methods can help protect or promote the right to food. The ethical challenges related to carbon dioxide removal methods are, we note, similar to those that will also be faced in the course of climate change mitigation. (shrink)

Radical forms of geoengineering, such as stratospheric sulfate injection (SSI), raise serious concerns about justice and the plight of the most vulnerable. However, these are sometimes dismissed on the basis of a challenge: “What if, in the face of catastrophic impacts, the most vulnerable countries initiate geoengineering themselves, or beg the richer, more technically sophisticated countries to do it? Wouldn’t geoengineering then be ethically permissible? Who could refuse them?” As a US tech billionaire put it, “Frankly, the (...) Maldives could say, ‘F--- you all—we want to stay alive’. Would you blame them? Wouldn’t any reasonable country do the same?” Such questions are intended to be rhetorical: it is assumed simply to be obvious that the appeals of the desperate would justify radical geoengineering. Moreover, the framing suggests that other nations would have strong moral reasons either to respect intervention by the desperate, or even to aid them by deploying themselves. Sometimes such arguments are also used to justify accelerating research on geoengineering now. If the desperate might attempt geoengineering, it is said, we should work out how best to do it, so as to assist them through advice. In general, the overriding thought is that the threat of catastrophe coupled with the plight of vulnerable populations provides most of the justification needed for the wider pursuit of a geoengineering agenda. Desperation becomes a trump card in the policy discourse. In this article, I argue that the desperation argument misses much of what is at stake, ethically speaking, in geoengineering policy. I focus on two further questions. The more obvious—the justificatory question—asks “under what conditions would geoengineering become justified?”, where the conditions to be considered would include, for example, the threat to be confronted, the governance mechanisms, the individual protections to be provided, the compensation provisions to be made, and so on. The less obvious question is the contextual question: “What is the ethical context within which geoengineering is likely to occur, and what difference does this make to our analysis of it?” (Gardiner 2013). In light of this distinction, I argue for two claims. First, on neither of the two most obvious interpretations of it does the desperation argument clearly justify the pursuit of geoengineering. Indeed, it may even count against such pursuit. Second, in any case, the context in which SSI is actually being pursued reveals more about the live threats and ethical import of geoengineering. For example, to push the most vulnerable to the point where they feel forced to accept pronounced subjugation to those who have made them desperate is a morally horrifying prospect which we have strong ethical reason to avoid. Such possibilities should not be concealed behind the superficial bravado of “f--- you all” and “what any reasonable country would do.” None of this implies that ethical geoengineering is impossible. However, it does suggest that geoengineering is morally complex in ways unappreciated by simple appeals to desperation. (shrink)

Many have argued that that it is morally wrong to benefit from an agent's culpable wronging of a third party. This thought has formed the basis of some arguments that agents can have duties to make up for wrongful acts by others that they could not have stopped, or that occurred before they were born. For example, it has been argued that those who benefited from slavery, colonialism and other shameful events in their nation's history should surrender those benefits, their (...) equivalent value, or provide other forms of redress. Some have also argued that it is morally wrong to benefit from unjust situations caused by third parties even where there is no culpable element. These ideas have potential to be a principle of redress for harms that are caused by the working of very complex systems, such as the global climate system. Geoengineering, the intentional manipulation of the global climate, is a new development in climate science and policy — and one which raises many normative challenges. This article focuses on one specific challenge. The global climate is very complex and there is a real possibility that the best available science will not be able to account for all the consequences of deploying a geoengineering technique. Therefore, any governance regime that allows deployment will have to consider how to organise compensation or redress for any adverse impacts that could not have been predicted at the time of deployment. This article proposes that, with some modification, the principle that agents should surrender benefits that have accrued to them from using geoengineering techniques, can be a good basis for such a scheme.

There is widespread agreement that ethical concerns are central to decision-making about, and governance of, geoengineering. This is especially true of the most prominent and paradigm example of climate engineering, the spraying of sulfate particles into the stratosphere in order to block incoming sunlight and so limit global warming ). Geoengineering ethics, like geoengineering science, is still in its early, exploratory days. This chapter offers an introductory overview of the emerging discussion and some of the challenges moving (...) forward, taking SSI as its key example. It identifies a range of values relevant to geoengineering, exposes some misleading early framings, argues that questions of justification and context are both important, and summarizes the Tollgate principles for geoengineering governance. One theme is that despite the initial agreement on the centrality of ethics, in practice there are profound risks that ethical considerations will be marginalized, both in the short-term as research is developed, and in the longer-run, in any deployment.

It is generally recognised that the potential positive and negative impacts of geoengineering will be distributed unevenly both geographically and temporally. The question of distributive justice in geoengineering thus is one of the major ethical issues associated with geoengineering. Currently, the question of distributive justice in geoengineering is framed in terms of who gets what (potential) benefits and harms from geoengineering, i.e. it is about the distribution of the outcomes of geoengineering. In this paper, (...) I argue that the discussions on distributive justice in geoengineering should not be outcome-based. Instead, it should be risk-based. I identify two problems for framing the question of distributive justice in geoengineering in terms of the distribution of its outcomes, i.e. the ‘if and then’ syndrome and the limited applicability of distributive principles in geoengineering policy, and suggest risk is a more proper object of distribution in the case of geoengineering. Following Hayenhjelm, I argue that the object of distribution in the case of fair distribution of risk should be (i) sources of risks and (ii) precautionary measures. I shall then demonstrate how it can be applied to the question of distributive justice in geoengineering. Finally, I end this paper by exploring the possible responses to the question of distributive justice in geoengineering by three major accounts of distributive justice, i.e. egalitarianism, prioritarianism, and sufficientarianism.

Although it could avoid some harmful effects of climate change, sulphate aerosol geoengineering (SAG), or injecting sulphate aerosols into the stratosphere in order to reflect incoming solar radiation, threatens substantial harm to humans and non-humans. I argue that SAG is prima facie ethically problematic from anthropocentric, animal liberationist, and biocentric perspectives. This might be taken to suggest that ethical evaluations of SAG can rely on Bryan Norton's convergence hypothesis, which predicts that anthropocentrists and non-anthropocentrists will agree to implement the (...) same or similar environmental policies. However, there are potential scenarios in which anthropocentrists and non-anthropocentrists would seem to diverge on whether a particular SAG policy ought to be implemented. This suggests that the convergence hypothesis should not be relied on in ethical evaluation of SAG. Instead, ethicists should consider the merits and deficiencies of both non-anthropocentric perspectives and the ethical evaluations of SAG such perspectives afford. (shrink)
