Geoengineering governance

This page brings together work on the governance and regulation of solar geoengineering research and deployment.

The challenges of governing geoengineering were one theme in my PhD research. More recently, in the ISPACE project we have been considering the implications of geopolitics for geoengineering development and governance.

In 2021 I collaborated with fellow CSSN scholars Jennie Stephens, Kevin Surprise and Prakash Kashwan in assessing the proposals for solar geoengineering research advocated by the US National Academies  ('Reflecting Sunlight'), generating a short Letter in Science, and a longer perspective article in Environmental Politics. 

In 2022 I became one of the 'First Signatories' to an academic call for a 'Non-Use Agreement on Solar Geoengineering'
