As part of the EU’s Mission on Adaptation to climate change, the ARCADIA project fosters large-scale system transformations that build resilient, future-proof regions across continental Europe. It developed a Self-Assessment Scorecard, designed to help organizations gauge their progress towards transformational change, a Guide of Guidance, offering practical steps and tools for effective climate resilience and two Policy Briefs, which translate current research and on-ground experience into actionable guidance for policymakers.
