Many philosophers have objected to Kant’s account of duties regarding non-human nature, arguing that it does not ground adequate moral concern for non-human natural entities. However, the traditional interpretation of Kant on this issue is mistaken, because it takes him to be arguing merely that humans should abstain from animal cruelty and wanton destruction of flora solely because such actions could make one more likely to violate one’s duties to human beings. Instead, I argue, Kant’s account of duties regarding nature grounds much stronger limitations on how humans may treat non-human animals and flora, since such duties are rooted in the imperfect duty to increase one’s own moral perfection. This duty proscribes actions affecting non-human nature that decrease one’s moral perfection, such as those that cause organisms unnecessary harm. Moreover, the duty to moral perfection prescribes (but does not strictly require) actions affecting non-human nature that increase one’s moral perfection, such as those that benefit organisms. Given this interpretation, I show that, contrary to a widely held view, Kant’s moral philosophy can ground a coherent and robust approach to environmental ethics.

Moral error theorists hold that morality is deeply mistaken, thus raising the question of whether and how moral judgments and utterances should continue to be employed. Proposals include simply abolishing morality, adopting some revisionary fictionalist stance toward morality, and conserving moral judgments and utterances unchanged. I defend a fourth proposal, namely revisionary moral expressivism, which recommends replacing cognitivist moral judgments and utterances with non-cognitivist ones. Given that non-cognitivist attitudes are not truth apt, revisionary expressivism does not involve moral error. Moreover, revisionary expressivism has the theoretical resources to retain many of the useful features of morality, such as moral motivation, moral disagreement, and moral reasoning. Revisionary expressivism fares better than the three major alternatives in both avoiding moral error and preserving these useful features of morality. I also show how this position differs from the “revolutionary expressivism” of Sebastian Köhler and Michael Ridge.

In this book, Toby Svoboda develops and defends a Kantian environmental virtue ethic, challenging the widely-held view that Kant's moral philosophy takes an instrumental view toward nature and animals and has little to offer environmental ethics. On the contrary, Svoboda posits that there is good moral reason to care about non-human organisms in their own right and to value their flourishing independently of human interests, since doing so is constitutive of certain virtues. Svoboda argues that Kant’s account of indirect duties regarding nature can ground a compelling environmental ethic: the Kantian duty to develop morally virtuous dispositions strictly proscribes unnecessarily harming organisms, and Svoboda argues that this duty compels us to act in ways that benefit non-human organisms, given that doing so can enhance one’s virtues. Svoboda’s argument engages the recent literature on environmental virtue and provides an original argument for an environmental virtue ethic firmly rooted in Kant’s moral philosophy

We thank the commentators for their interesting and helpful feedback on our previously published target article (Svoboda and Irvine, 2014). One of our objectives in that article was to identify areas of uncertainty that would need to be addressed in crafting a just SRM compensation system. The commentators have indicated some possible ways of reducing such uncertainty. Although we cannot respond to all their points due to limitations of space, we wish to address here the more pressing criticisms the commentators have offered.

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.

The position of some environmental ethicists that some non-humans have intrinsic value as a mind-independent property is seriously flawed. This is because human beings lack any evidence for this position and hence are unjustified in holding it. For any possible world that is alleged to have this kind of intrinsic value, it is possible to conceive an observationally identical world that lacks intrinsic value. Hence, one is not justified in inferring the intrinsic value of some non-human from any set of observable properties, since that same set of properties could just as well exist in a world that lacks intrinsic value. However, since human beings do not have a faculty of intuition that would allow them to ..

As a response to climate change, geoengineering with solar radiation management has the potential to result in unjust harm. Potentially, this injustice could be ameliorated by providing compensation to victims of SRM. However, establishing a just SRM compensation system faces severe challenges. First, there is scientific uncertainty in detecting particular harmful impacts and causally attributing them to SRM. Second, there is ethical uncertainty regarding what principles should be used to determine responsibility and eligibility for compensation, as well as determining how much compensation ought to be paid. Significant challenges loom for crafting a just SRM compensation system
