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.

Ethicists and social scientists alike have advocated for the inclusion of vulnerable populations in research and decision-making on climate engineering. Unfortunately, there have been few efforts to do so. The research presented in this paper was designed to build knowledge about how vulnerable populations think about climate engineering. The goal of this manuscript is to bring the ethics literature on climate engineering into dialogue with emerging social science data documenting the perspectives of vulnerable populations. The results indicate some concerns among (...) vulnerable populations may resemble those outlined by ethicists. However, the perspectives expressed by interviewees also extend previous ethical treatments by indicating ways in which climate engineering could compound existing injustices. (shrink)

It has been argued that geoengineering research should not be pursued because of a slippery slope from research to problematic deployment. These arguments have been thought weak or defective on the basis of interpretations that treat the arguments as relying on dubious premises. The paper urges a new interpretation of these arguments as precautionary arguments, i.e. as relying on a precautionary principle. This interpretation helps us better appreciate the potential normative force of the worries, their potential policy relevance, and the (...) kind of evidence required by slippery slope arguments. Understood as precautionary arguments, it is clear that slippery slope arguments against geoengineering capture concerns that are worth taking seriously. (shrink)

Much in Responsible Research and Innovation (RRI) is part of a participatory turn within the Technology Assessment (TA) and Science and Technology Studies (STS) community. This has an influence also on the evaluation of Climate Engineering (CE) options, as it will be shown by reference to the SPICE project. The SPICE example and the call for democratisation of science and innovation raise some interesting concerns for the normative evaluation of CE options that will be addressed in the paper. It is (...) by far not clear, or so it will be argued, how much of the innovation process of CE technologies should be put in the hands of social actors and the wider public. This is due not only to special features about CE technologies but also to some more principle concerns against some features of participatory RRI approaches. Still, this does by no way mean that ethical and societal issues in the context of CE technologies should be ignored. Rather, the paper will argue that one can take a step back to expert TA linked to the evolution of approaches of ethical impact analysis in this area. This does not only lead to reconsider the emphasis on participation and democratisation of research and innovation, but also opens up for an alternative evaluative framework for CE technologies developed in the last part of the paper.
