ICLEI is a global network of more than 2,500 local and regional governments dedicated to advancing sustainable urban development. Operating in over 125 countries, the organization shapes sustainability policies and supports local efforts to build zero-emission, nature-based, equitable, resilient, and circular communities.

Integrating Sustainability into Urban Development

The organization works to embed sustainability within the fast-changing landscape of urban growth. ICLEI promotes systemic transformation in cities and regions by providing practical and integrated solutions. Through its work, local governments are better equipped to anticipate and address complex challenges such as rapid urbanization, climate impacts, environmental degradation, and social inequity.

Addressing Challenges Through Local Action

Members of the ICLEI network approach these challenges by incorporating sustainability into their daily planning, operations, and policy development. ICLEI strengthens local capacity by ensuring governments have access to the knowledge, data, and scientific insights required to make informed decisions. Its five pathways—low emission, nature-based, equitable, resilient, and circular development—serve as a framework for long-term systemic change.

Empowering Cities and Regions of All Sizes

ICLEI collaborates with communities of all sizes, each with unique contexts and priorities. Some member governments are global leaders in sustainability, driving innovation and pioneering bold new approaches. Others are beginning their transition, focusing on building stronger systems and capacities to meet their sustainability goals.

Across all regions, ICLEI works to connect global expertise with local realities, ensuring that the latest knowledge and solutions are accessible to cities, towns, and regions around the world.
