Preston's (2011) challenge to the moral presumption against geoengineering is applied to carbon dioxide capture and storage (CCS) in Scotland, United Kingdom. Qualitative data is analysed to assess if and how Preston's arguments play out in practice. We argue that the concepts of ‘lesser evil’ and prioritising human well-being over non-interference in natural processes do bring different value positions together in support of CCS, but that not all people see short-term carbon abatement as the ‘least (...) worst’ option or a suitable way to prioritise human well-being.

Although extensive research has been devoted to public perceptions and acceptance of controversial energy innovations, the perspectives of people developing and implementing such technologies are relatively under-examined. Other industries, such as mining, and social researchers have adopted the term “social licence to operate” (SLO) to conceptualise community–industry relationships. Despite its potential applicability to carbon dioxide capture and storage (CCS) technology, SLO has received very little attention in this context, specifically from an engineering and managerial perspective. The (...) internationally contested nature of CCS highlights the importance of examining how engineers and managers discuss and understand the term SLO. Given the central role of engineers and managers in developing CCS technology and contributing to the creation of the contexts in which people relate to it, knowledge of how they understand their connection to communities impacted by the technology is a key area requiring deve..

The risk posed by anthropogenic climate change is generally accepted, and the challenge we face to reduce greenhouse gas (GHG) emissions to a tolerable limit cannot be underestimated. Reducing GHG emissions can be achieved either by producing less GHG to begin with or by emitting less GHG into the atmosphere. One carbon mitigation technology with large potential for capturing carbon dioxide at the point source of emissions is carbon capture and storage (CCS). However, the (...) merits of CCS have been questioned, both on practical and ethical grounds. While the practical concerns have already received substantial attention, the ethical concerns still demand further consideration. This article aims to respond to this deficit by reviewing the critical ethical challenges raised by CCS as a possible tool in a climate mitigation strategy and argues that the urgency stemming from climate change underpins many of the concerns raised by CCS.

Non-technical summary: -/- When developing and deploying negative emissions technologies (NETs), little attention has been paid to where. On the one hand, one might develop NETs where they are likely to contribute most to global mitigation targets, contributing to a global climate solution. On the other hand, one might develop NETs where they can help support development on a regional basis, justified by regional demands. I defend these arguments and suggest that they reflect the values of efficiency and responding to (...) need, respectively. To the extent that these values conflict, they introduce what I call the Need-Efficiency Trade-off Effect (‘NET Effect’). -/- Technical summary: -/- Unlike other geoengineering methods, the effectiveness of negative emissions technologies (NETs) tends to be sensitive to regional siting. This paper argues that this point raises morally and legally important implications by identifying a trade-off between ‘efficiency’ and ‘need’. First, it introduces two arguments justifying NETs: one focused on contributions to global mitigation and the other focused on contributions to regional development. Second, reflecting the two arguments, the paper discusses the moral values of efficiency and need, respectively. For instance, if the strategy is to try to use NETs to maximize expected mitigation contributions to reflect efficiency, then deployment should occur in regions with the best prospects for success (e.g. Western countries). However, if the strategy is to try to use NETs to improve the chances of simultaneous development and mitigation to respond to need, then deployment should occur in regions with limited development and expected growth of demand for NETs (e.g. Asian countries). When these values conflict, I call that a Need-Efficiency Trade-off Effect (‘NET Effect’). The paper concludes by considering the NET Effect in the context of bioenergy with carbon capture and storage as well as direct air carbon capture and storage. [Open access]. (shrink)
