This paper, in collaboration with Carnegie Climate Governance Initiative (C2G), identifies the governance gaps associated with solar radiation modification (SRM). It divides SRM’s governance dimensions and challenges into those that would arise at various stages of its research, development, and possible use.
SRM is being explored as a potential approach to reduce climate change impacts in addition to emissions reduction, removal, and adaptation. Progress toward reducing greenhouse gases emissions remains insufficient, and emissions are on track to significantly overshoot the Paris Agreement’s temperature goals. SRM appears to have the potential to reduce — but not eliminate — some climate change impacts. However, it could pose other risks, which would depend on the specifics of how it is implemented. The current governance landscape for SRM is limited but not vacant.
Solar Radiation Modification presents a high stakes risk-risk trade-offs with significant governance gaps and uncertainties, related to deciding, managing, implementing, monitoring, and adjudicating policies and actions.
