Biodiverse cities understand that a diverse natural world is the foundation of human existence, as it is necessary for both survival and quality of life.


ICLEI - the global cities network

We are a powerful movement of 12 mega-cities, 100 super-cities and urban regions, 450 large cities as well as 450 small and medium-sized cities and towns in 84 countries dedicated to sustainable development.

Connecting Leaders

Global action partners

ICLEI welcomes the opportunity for collaboration and complementary action that partnerships bring. Over the years we have forged winning partnerships with national governments, international agencies, academic institutions, for profit companies, foundations and non-governmental organizations, and dozens of national, regional, and international associations of local governments.  

ICLEI offers many opportunities for partnerships with financing institutions, the private sector, universities and expert institutions and with united nations and international agencies.

Accelerating Action

Go to where the action is as an ICLEI Member

ICLEI Members are as diverse as the local governments, prefectures, municipalities, and counties from which they come. What all ICLEI Members have in common is a commitment to sustainable local urban development.

Gateway to solutions

Solutions oriented change

Cities are leading global change. For decades cities on every continent have been setting the bar for urban sustainability, conservation of biodiversity, and climate protection. When one city has raised the bar, it can provide a blue print for continuous improvements and innovation from which other cities can learn and then adapt to their needs. ICLEI is proud to work with these leading actors on the urban sustainability stage.
