The European Union built its international identity, in significant part, on a promise: that it would lead the world in translating climate science into law, and that prosperity and sustainability are complementary rather than competing goals. That promise generated the European Green Deal, the Fit for 55 package, global EU climate diplomacy, and — critically for countries in the Global South — expectations that supply chain accountability, means of implementation, and new forms of climate finance would follow.

It is now worth asking, plainly, whether that promise is still there and whether the EU is ready and willing to keep it. This briefing takes stock of the EU's direction of travel across the interconnected domains of climate, trade, biodiversity, pollution, and health, drawing on legislative and policy developments over the 2025–2026 period. It is part of SLYCAN Trust's EU governance monitoring series and should be read alongside the companion regulatory briefing: From Transition to Triage? Shifting Budget Priorities in the EU and Their Impact on the Green and Just Transition 2025 and Beyond (November 2025); Reflection on EU Instruments and the Green Deal: Strategic Adaptation or Retreat? (December 2025); The Maritime Sector: Perspectives on Security, Climate Change, and the Environment (January 2026); The EU Industrial Accelerator Act: Industrial Policy with a Green Veneer, or a Genuine Decarbonisation Driver? (April 2026); and Critical Raw Materials: State of Play and Integrating Environmental and Social Concerns (July 2026). A detailed analysis of the implications for developing countries and the UNFCCC process is being developed in two companion briefs currently in preparation.
