Why join ICLEI? Let ICLEI officers and staff from around the world, headed by our President, Seoul Mayor Park Won-soon, explain what we do for our Members in this video celebrating 25 years of ICLEI.

Local spheres of government (local and regional governments and authorities), as defined in the particular country, and international, regional, national and sub-national associations of such municipal governments and authorities, may become ICLEI Members.

The only requirements are the payment of modest annual dues based on population size in accordance with the country GNI per capita. ICLEI also encourages its Members to make a self-defined commitment to its citizens to address climate change and sustainability.
