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 13 offices and 220 staff.

ICLEI's history

Our membership has continuously grown. 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.

ICLEI's Governance and Strategic Plan
Our 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.
  • Connecting Leaders – Be a growing Association of local governments dedicated to sustainable development with a worldwide presence, which has challenging positions, whose voice is heard, and which is attractive to be a member of, work for and partner with. To enable our members to achieve their local aims and goals, ICLEI supports a network around them that connects cities to other organizations on a local, national and international level and enables local cities to make their voices heard.

  • Accelerating Action – Be a high-energy, flexible Movement of local governments working together in networks for performance, supported by campaigns and programs, and strategic alliances. How do we provide this platform? We forge partnerships or alliances, engage with leading thinkers and academics, join forces with the business sector, and work jointly on pilot projects, meet at congresses and events and unite local leaders in their common work.

  • Gateway to Solutions – Be an effective sustainability and environmental Agency demonstrating creativity and excellence both in developing cutting edge solutions and in program design and execution. Look for local solutions to global challenges by connecting local leaders to global partners such as international organizations, business, entrepreneurs, academic or other non-governmental organizations and experts in the field of sustainability.
    ICLEI provides technical consulting, information services and training to build capacity, share knowledge and support local governments in the implementation of sustainable development at the local level.
