ICLEI is the leading global network of 1,500+ cities, towns and regions committed to building a sustainable future. Through our collective efforts, we impact more than 25 percent of the global urban population.
Local and regional governments across the ICLEI network work alongside a diverse team of global experts in 22 offices active across 124 countries. Together, ICLEI addresses the local impacts of unprecedented global change, from climate change to urbanization, aiming for urban development to have the least possible impact on global systems and to build communities that are people-centered and equitable.
