Celebrating 10 years of RegionsAdapt
a global initiative supporting subnational governments in adapting to climate change.
A Decade of Impact
A global platform of 85+ States and regions leading on climate adaptation
Representing over 470 million people working to assess risks, plan, and implement adaptation
41 reporting regions have implemented 328 adaptation actions
The First Global Initiative Supporting Governments on Climate Adaptation
Over the past decade, members have scaled up adaptation, shared knowledge, and brought regional perspectives to international climate discussions.
Climate change is intensifying, and regions are on the frontlines. RegionsAdapt, launched in 2015 at COP21, alongside the adoption of the Paris Agreement, is the first global initiative dedicated to supporting subnational governments in climate change adaptation. It supports states and regions in turning climate risks into action through four essential steps of the adaptation cycle: assessing vulnerabilities, planning ambitious strategies, acting through adaptation measures, and reporting to share lessons and strengthen policies.
By joining, governments commit to concrete steps that protect communities, ecosystems, and economies. Over ten years, RegionsAdapt continues to empower regions and invites new governments to join, reinforcing their role as key actors in building climate-resilient territories.
