Why Join

Subnational governments have a critical role to play in addressing climate change and ensuring concrete results of adaptation actions. They have authority over key aspects of climate policy, including energy, transportation, and the build environment, and play a fundamental role enhancing coordination and cooperation across all levels of government.

RegionsAdapt is an opportunity for regional governments to:

  1. Join an ambitious global group of subnational governments who are pioneer in climate change adaptation;
  2. Have a platform to showcase their regional actions on adaptation;
  3. Establish an extensive communication with other governments, offering and learning best practices;
  4. Become part of a global, standardized reporting system;

Take part in CDP’s global reporting system and

join over 71 states and regions, 5,600 companies,

and 533 cities, that already measure, manage and

report their vital environmental information.
