carbonn Climate Registry


Under the auspices of the World Mayors Council on Climate Change and with the endorsement of United Cities and Local Governments (UCLG) and the Club of Madrid, the carbonn Climate Registry (cCR) has been developed with support from ICLEI – Local Governments for Sustainability and the Government of Mexico City. The cCR is operated by the Bonn Center for Local Climate Action and Reporting – carbonn®.

Developed by ICLEI with the support of the City of Copenhagen, the cCR builds upon the City Climate Catalogue which was the first global collection to centralise facts and figures on community climate action – from targets to achievements.

As part of the Local Government Climate Roadmap process of which UCLG is also a partner, the cCR is used to present a strong case for local and subnational governments during the international climate negotiations towards a post-2020 global climate agreement.
