ICLEI supports its members to find sustainable solutions by creating a movement of peers driving positive change on a European and global scale through projects, initiatives, and programmes. We offer cities a platform to engage with peers, alongside resources and tools to instigate positive environmental, economic, and social change.

ICLEI also champions the role of local governments on the European and international policy stage, providing them with a clear voice and ensuring that their views are heard. We work closely together with European networks, the European Commission, the Committee of the Regions and many other organisations advancing sustainability.
