Over the last decade, EU policy has employed both an indirect, context-shaping approach to climate security, which focuses more on process than output, and a protective-autonomy approach, which focuses on multiple defensive approaches to safeguard the EU’s geopolitical interests. In putting these approaches into practice, the EU has advanced a rich profusion of climate security initiatives; diplomats certainly do not need to be told that “climate policy is foreign policy,” as they have been working on this assumption for more than a decade. Moreover, the EU’s approach has positioned the bloc well to play a constructive role in climate geopolitics. However, the union’s overall approach to climate security has been relatively narrow. It has built select climate elements into its existing security strategies rather than rethinking what security itself entails in a world challenged by widespread ecological disruptions.
