1. Barry and Cullity (2022b) argue that when morally assessing a person’s climate actions,1 we should ask how these actions affect other people’s prospects.2 For the present purposes, we can unders...

A growing number of decision theorists have, in recent years, defended the view that rationality is permissive under risk: Different rational agents may be more or less risk-averse or risk-inclined. This can result in them making different choices under risk even if they value outcomes in exactly the same way. One pressing question that arises once we grant such permissiveness is what attitude to risk we should implement when choosing on behalf of other people. Are we permitted to implement any (...) of the rationally permissible risk attitudes, is there some specific risk attitude that is required when choosing for others, or are we required to defer to the risk attitudes of the people on whose behalf we are choosing? This article elaborates on this question, explains its wider practical and theoretical significance, provides an overview of existing answers, and explores how to go about providing a more systematic account of how to choose on behalf of others in risky contexts.

ABSTRACT We have previously argued that there are forms of greenhouse gas offsetting for which, when one emits and offsets, one imposes no risk. Orri Stefansson objects that our argument fails to distinguish properly between the people who stand to be harmed by one’s emissions and the people who stand to be benefited by one’s offsetting. We reply by emphasizing the difference between acting with a probability of making a difference to the distribution of harm and acting in a way (...) that worsen’s someone’s prospect. (shrink)

ABSTRACT Offsetting is a very ineffective way to do good. Offsetting your lifetime emissions may increase aggregated life expectancy by at most seven years, while giving the amount it costs to offset your lifetime emissions to a malaria charity saves in expectation the life of at least one child. Is there any moral reason to offset rather than giving to some charity that does good so much more effectively? There might be such a reason if your offsetting compensated or somehow (...) benefitted the victims of your emission, since that could mean that you would satisfy the duty not to harm others by emitting and offsetting. But that is typically not true. If your emission harms some person and your offsetting benefits some person, then these are most likely different people. Hence, I conclude, we have a stronger reason to give to effective charities than we have to offset our emissions. (shrink)

It is typically wrong to act in a way that foreseeably makes some impending harm worse. Sometimes it is permissible to do so, however, if one also offsets the harm increasing action by doing something that decreases the badness of the same harm by at least as much. This chapter argues that the standard deontological constraint against doing harm is not compatible with the permissibility of harm increases that have been offset. Offsetting neither prevents one's other actions from doing harm (...) nor ensures that the harm those actions do is made permissible by any of the constraint's familiar provisos. To make sense of offsetting, the old constraint against doing harm should be replaced with a new constraint against making unoffset harm increases. The chapter discusses how to formulate the new constraint so that it can handle both the offsetting cases that the old constraint gets wrong as as well as the non-offsetting cases that the old constraint gets right. Adopting this constraint against unoffset harm increases may have important implications both for theoretical questions about the sources of deontological constraints as well as for practical questions, such as whether buying carbon offsets can make emitting carbon dioxide permissible.

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

This essay argues that when setting climate policy, we should place more weight on worse possible consequences of a policy, while still placing some weight on better possible consequences. The argument proceeds by elucidating the range of attitudes people can take towards risk, how we must make choices for people when we don’t know their risk-attitudes, and the situation we are in with respect to climate policy and the consequences for future people. The result is an alternative to the Precautionary (...) Principle, an alternative that gives similar policy recommendations in many cases but is also sensitive to the costs of precautions. (shrink)

Does it count against a normative theory in political philosophy that it is in some important sense infeasible, that its prescriptions are unlikely to be complied with? Though a positive answer seems plausible, it has proved hard to defend against the claim that this is not how normative theories work - noncompliance shows a problem with the noncomplying agents, not with the normative theory. I think that this line of thought - this defense of Utopianism - wins the battle but (...) loses the war. It’s right about what does and what does not refute a normative theory. It’s wrong in misidentifying the problem. The right way to think about the feasibility worry is as essentially involving multiple agents, and how expected noncompliance by one agent may refute a normative claim addressed at another. Thus understood, feasibility problems may very well refute a theory in political philosophy. In this paper I develop this understanding of the feasibility worry, tie it to more general discussions in normative ethics, and in political philosophy. (shrink)

We live in a morally flawed world. Our lives are complicated by what other people do, and by the harms that flow from our social, economic and political institutions. Our relations as individuals to these collective harms constitute the domain of complicity. This book examines the relationship between collective responsibility and individual guilt. It presents a rigorous philosophical account of the nature of our relations to the social groups in which we participate, and uses that account in a discussion of (...) contemporary moral theory. Christopher Kutz shows that the two prevailing theories of moral philosophy, Kantianism and consequentialism, both have difficulties resolving problems of complicity. He then argues for a richer theory of accountability in which any real understanding of collective action not only allows but demands individual responsibility. (shrink)

Carbon offsetting can be loosely characterized as a mechanism by which an organization or individual contributes to a scheme that is projected either to remove carbon dioxide from the atmosphere or to deliver carbon dioxide emission reductions on the part of other organizations or individuals. An activity that has been offset therefore purports to make no long-term net contribution to atmospheric greenhouse gas concentrations. The ethical basis for using carbon offsetting as an approach to tackling climate change is very much (...) contested. We seek to expose some of the underlying reasons for these ethical disagreements. We show that they relate both to empirical disagreements about what the likely benefits of offsetting are and, more fundamentally, to principled disagreements about the right way to discharge duties to deliver carbon reductions.

Esteemed philosopher John Broome avoids the familiar ideological stances on climate change policy and examines the issue through an invigorating new lens. As he considers the moral dimensions of climate change, he reasons clearly through what universal standards of goodness and justice require of us, both as citizens and as governments. His conclusions—some as demanding as they are logical—will challenge and enlighten. Eco-conscious readers may be surprised to hear they have a duty to offset all their carbon emissions, while policy (...) makers will grapple with Broome’s analysis of what if anything is owed to future generations. From the science of greenhouse gases to the intricate logic of cap and trade, Broome reveals how the principles that underlie everyday decision making also provide simple and effective ideas for confronting climate change. Climate Matters is an essential contribution to one of the paramount issues of our time. (shrink)

Many companies offer their customers voluntary carbon ‘offset’ certificates to compensate for greenhouse gas emissions. Voluntary offset certificates are cheap because the demand for them is low, allowing consumers to compensate for their emissions without significant sacrifices. Regarding the distribution of emission reduction responsibilities I argue that excess emissions are permissible if they are offset properly. However, if individuals buy offsets only because they are cheap, they fail to be robustly motivated to choose a permissible course of action.This suspected lack (...) of robust motivation raises both pragmatic questions about the functioning of offsetting schemes and moral questions about the worth of such unstable motives. The analysis provided here also has wider implications for the normative analysis of partial compliance and ‘many hands’ problems, especially for those cases where compliance levels and costs interact.

Suppose you perform two actions. The first imposes a risk of harm that, on its own, would be excessive; but the second reduces the risk of harm by a corresponding amount. By pairing the two actions together to form a set of actions that is risk-neutral, can you thereby make your overall course of conduct permissible? This question is theoretically interesting, because the answer is apparently: sometimes Yes, sometimes No. It is also practically important, because it bears on the moral (...) status of practices such as offsetting personal greenhouse gas (GHG) emissions. In this article we propose a criterion for distinguishing between cases where pairing risk-increasing and risk-reducing actions makes each action permissible, and those where it does not: the Principle of Aggregate Risk-Imposition. We work towards this by considering a range of examples that illustrate various illegitimate ways of pairing risk-increasing actions with risk-reducing ones, and asking what goes wrong in each case. We then use this criterion to evaluate GHG offsetting. Is offsetting a legitimate way of removing the risk-imposition associated with GHG emissions, or not? Controversially, we argue that this turns out to depend on the form that the offsetting takes. (shrink)

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

Why act when the effects of one’s act are negligible? For example, why boycott sweatshop or animal products if doing so makes no difference for the better? According to recent proposals, one may still have a reason to boycott in order to avoid complicity or participation in harm. Julia Nefsky has argued that accounts of this kind suffer from the so-called “superfluity problem,” basically the question of why agents can be said to participate in harm if they make no difference (...) to it. This paper develops and responds to Nefsky’s challenge. (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)
