Climate Security, Energy Transition and Green Defence as a Strategic Priority in Euro-Atlantic Security

Climate security and energy transition have moved from being treated as primarily environmental and economic agendas to being framed, by Euro-Atlantic institutions, as strategic variables that affect deterrence, defence readiness, resilience, and the capacity to sustain operations under stress.

In the Euro-Atlantic space, the formal political anchor is the recognition of climate change as a “threat multiplier” affecting collective security, explicitly stated at summit level and tied to the Alliance’s core responsibility to protect territory and populations. The consolidation of this priority is best understood as the convergence of three structural dynamics.

This analysis answers: How have Euro-Atlantic institutions reframed climate security and energy transition as strategic variables affecting deterrence and readiness? What does the "threat multiplier" political anchoring imply for the Alliance's core responsibilities? Which capability families, tactical building blocks and technology clusters are implicated in green defence? What structural bottlenecks and strategic dependencies affect institutions, industry, research and capital?
