The European Union stands at a critical juncture aiming to externalise its Green Deal in a complex geopolitical environment. The Green Deal is the most advanced political and technical proposition to chart forward a regional climate transition.

The EU needs to develop a full-fledge ecological diplomacy approach at the heart of its foreign policy. In her research, Olivia Lazard will focus on a specific case study to illustrate what a context-specific ecological approach can look like.
