Towards an Energy-Climate-Defence Nexus in the European Union and beyond? – Reflections on concept and assessment of an emerging nexus

The energy-climate-defence nexus is an emerging research and policy concept that examines the complex and interrelated relationships between energy policy, climate change and de-fence. While the nexus approach is widely recognised in theory, there is a lack of clear con-ceptual depth and a systematic assessment framework, particularly with regard to a ‘triple nexus’ that combines these three dimensions. This article discusses the existing concepts and shows that, although the existing literature and political practice represent first steps to-wards an energy-climate-defence nexus, essential elements of a comprehensive nexus ap-proach are still missing. In initial considerations, the article outlines the concept and possi-ble framework conditions of an energy-climate-defence nexus.
