This network for Sustainability is the world's leading association of cities and local governments dedicated to sustainable development. This network is 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. This network promotes local action for global sustainability and supports cities to become sustainable, resilient, resource efficient, bio-diverse, low-carbon; to build a smart infrastructure; and to develop an inclusive, green urban economy. The ultimate aim is to achieve healthy and happy communities. We have developed stable, long-term programs to support local-level sustainability and continue to develop innovative new programs to respond to issues of international concern. The Council was established when more than 200 local governments from 43 countries convened at our inaugural conference, the World Congress of Local Governments for a Sustainable Future, at the United Nations in New York.
