ICLEI - Local Government for Sustainability

ICLEI has grown to become the largest international association of local governments as determined by budget, personnel and scale of operations.

We have expanded from two offices in 1991 to our current 14 offices and 200 staff.

ICLEI's membership continues to expand at a rate of approximately 10% annually. We have developed stable, long-term programs to support local-level sustainability and continue to develop innovative new programs to respond to issues on the international agenda.



  • A growing Association of local governments dedicated to sustainable development with worldwide presence, which has challenging positions, whose voice is heard, and which is attractive to be a member of, work for and partner with;
  • A high-energy, flexible Movement of local governments working together in networks for performance, supported by campaigns and programs, and strategic alliances;
  • An effective sustainability and environmental Agency demonstrating creativity and excellence both in developing cutting-edge solutions and in program design and execution.

Mission and Mandate

ICLEI's mission is to build and serve a worldwide movement of local governments to achieve tangible improvements in global sustainability with special focus on environmental conditions through cumulative local actions.

ICLEI's general mandate is to build an active and committed municipal membership of local spheres of government (local and regional governments and authorities) as well as international, regional, national and sub-national local government associations.
