Evidence Brief: Governing Solar Radiation Modification
This briefing summarises the latest evidence around Marine Cloud Brightening (MCB) and Stratospheric Aerosol Injection (SAI), two important types of Solar Radiation Modification climate-altering technologies. It describes the techniques, explores their technical readiness, current research, applicable governance frameworks, and other socio-political considerations. It provides an analysis of the types of geopolitical issues and concerns, including security, that the technologies may give rise to and how existing governance does or does not help address those. It also provides an overview of key existing governance instruments of relevance to their governance.
