We present the first comprehensive theory of fairness that conceives of fairness as having two dimensions: a comparative and an absolute one. The comparative dimension of fairness has traditionally been the main interest of Broomean fairness theories. It has been analysed as satisfying competing individual claims in proportion to their respective strengths. And yet, many key contributors to Broomean fairness agree that ‘absolute’ fairness is important as well. We make this concern precise by introducing the Fairness formula and the absolute (...) priority rule and analyse their implications for comparative fairness. (shrink)

This book analyzes major ethical issues surrounding the use of climate engineering, particularly solar radiation management techniques, which have the potential to reduce some risks of anthropogenic climate change but also carry their own risks of harm and injustice. The book argues that we should approach the ethics of climate engineering via "non-ideal theory," which investigates what justice requires given the fact that many parties have failed to comply with their duty to mitigate greenhouse gas emissions. Specifically, it argues that (...) climate justice should be approached comparatively, evaluating the relative justice or injustice of feasible policies under conditions that are likely to hold within relevant timeframes. Likely near-future conditions include "pessimistic scenarios," in which no available option avoids serious ethical problems. The book contends that certain uses of SRM can be ethically defensible in some pessimistic scenarios. This is the first book devoted to the many ethical issues surrounding climate engineering.

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)

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.
