Solar Geoengineering: The View from Just War/Securitization Theories

As the world continues to fail to reduce and control global surface temperatures, the use of solar radiation management (SRM) technology by one actor or by a small coalition of actors is becoming increasingly likely. Yet, most of the social scientific literature on solar geoengineering does not tend to systematically engage with this possibility; scholars focus either on global governance or on banning SRM usage and research altogether. On the margins of this debate, a handful of researchers have sought to bring insights from the just war tradition to the issue of unilateral and minilateral SRM usage. This article is concerned with the contribution just war/securitization theories can make to our understanding of the debate surrounding climate engineering. It scrutinizes and deepens existing attempts by just war scholars to examine the moral permissibility of unilateral and minilateral SRM usage, including from the perspective of Just Securitization Theory.
