Driven by the governments of Rio de Janeiro and Catalonia, RegionsAdapt was launched at COP 21 in Paris. Regions4 coordinates this initiative that now encompasses 76 signatory regions from five continents impacting over 300 million citizens.

RegionsAdapt mobilizes ambition and action on climate adaptation by facilitating access to the latest innovations, tools and best practices at regional level throughout the world. Through knowledge sharing, capacity building, adoption of common standards, and contribution to the global processes, this unique regional partnership catalyzes innovation on climate adaptation, fosters cooperation and supports regional governments improve their resilience.

By joining the RegionsAdapt initiative, governments commit to:

  1. Prioritize and plan, adopting an adaptation plan or programme (mainstreaming adaptation into other sectors and/or policies) within the first two years of joining.
  2. Implement concrete actions on adaptation in key identified priority areas.
  3. Report annually on your adaptation progress through the CDP Online Reporting Platform.



Regional governments have a critical role to play in addressing climate change and ensuring concrete results of adaptation actions. They:

  • Have close and direct contact with citizens and are aware of the main challenges facing their territories, which allows them act together with inhabitants to implement proper and game-changer measures to build resilience.
  • Are key on fostering urban-rural linkages for effective integration of adaptation policies and sustainable development.
  • Promote an integrated territorial approach to enhance synergies between different sectors and stakeholders.
  • Have strategic competences on areas linked to climate policy such as energy, transportation and the build environment.
  • Are able to create strategic and powerful synergies with other regions in order to exchange knowledge and key initiatives on adaptation.
  • Are already leading in climate adaptation and collaborating with their National and local counterparts, facilitating multi-level governance for effective climate action.
