The C40 Cities Finance Facility (CFF) facilitates access to finance for climate change mitigation and resilience projects in urban areas by providing technical assistance to develop cities’ sustainability priorities into bankable investment proposals. The CFF aims to deliver project preparation and capacity development, and to widely share knowledge and establish partnerships between cities and financiers. Funded by the German Federal Ministry for Economic Cooperation and Development (BMZ), the Government of the United Kingdom and the United States Agency for International Development (USAID), the initiative is implemented by Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH together with the C40 Cities Climate Leadership Group.

On the CFF website users can apply for support as well as access updates, announcements, and resources from the CFF knowledge library.
