ICLEI - Local Governments for Sustainability is the leading global network of 1,750 cities, towns and regions committed to building a sustainable future.


By 2050, the global population is estimated to reach nine billion people of which two-thirds will be living in cities. Because of this, the role of municipalities is becoming increasingly crucial to make their cities and regions sustainable, low-carbon, resilient, ecomobile, biodiverse, resource-efficient and productive, healthy and happy, with a green economy and smart infrastructure.

ICLEI believes that cumulative voluntary actions on the local scale are indispensable in order to address worldwide environmental issues. As such, in order to address these environmental issues, ICLEI engages in various activities in support of regional efforts.
