International governance of climate engineering

Discussions of climate engineering (CE) governance stand now at a crucial juncture. While the CE research community’s ideas about governance have become increasingly sophisticated and specific over the last half decade, they have by and large not been translated into actual governance mechanisms. This working paper summarizes the main points of agreement among major reports on CE governance and lays out some major open questions. This paper also surveys those reports with a view to helping readers understand each report’s distinctive features and major recommendations regarding CE governance.
