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)

While the energy transition is needed more than ever, for some agents it brings significant losses. This article investigates whether fossil fuel owners could refer to promises to avoid having their assets stranded. It explains how authors, in the context of just transitions, have argued for the normative relevance of Rawlsian legitimate expectations, which refer to promissory entitlements. However, it argues that the normative relevance of promises towards fossil fuel owners is limited, because there are only few promises about what (...) will be permissible in the future and because these promises should be just before they can lead to entitlements.

This article focuses on the epistemic transition to testimonial justice. It argues that the recognition of testimonial injustice in the context of reproductive rights may play a central role in this transition. First, I show how testimonial injustice undermines women’s legal protection against sexual violence and rights triggered by it such as the right to abortion. Second, I argue that the epistemic transition initiated by the #MeToo and #YoSiTeCreo movements call for transitional justice. In support, I review the circumstances of (...) transitional justice for cases like the transition to testimonial justice. Finally, I focus on the area of reproductive rights. I argue that policies of recognition contribute to epistemic transitional justice and complement other strategies aimed to overcome testimonial injustice such as the virtue of the responsible hearer and institutional compensatory virtues.
