UN-Habitat is the United Nations entity responsible for developing urban policies and translating them into action to create sustainable cities and communities.
Cities are facing unprecedented demographic, environmental, economic, and social challenges. There has been a phenomenal shift towards urbanization, with half of the world's population living in cities. By 2050, almost 70 per cent of the population will reside in cities. This urban growth will be happening mainly in Africa, Asia, Latin America, and the Caribbean.
In the absence of effective urban planning, the consequences of this rapid urbanization will be dramatic. Urban policies need to change to turn this rapid urban growth into opportunities to create a better quality of life for people.
UN-Habitat is at the helm of this change. It is mandated by the UN General Assembly to address the issues of urban growth and sustainable urban development.
C40 is a network of nearly 100 mayors of the world’s leading cities who are working to deliver the urgent action needed right now to confront the climate crisis and create a future where everyone, everywhere, can thrive. Mayors of C40 cities are committed to using a science-based and people-focused approach to limit global heating in line with the Paris Agreement and build healthy, equitable, and resilient communities. Through a Global Green New Deal, mayors are working alongside a broad coalition of representatives from labour, business, the youth climate movement and civil society to go further and faster than ever before.
The current co-chairs of C40 are Mayor of London Sadiq Khan and Mayor of Freetown Yvonne Aki-Sawyerr. Three-term Mayor of New York City Michael R. Bloomberg serves as President Emeritus of the Board. C40’s work is made possible by our strategic funders: Bloomberg Philanthropies and Realdania.
