The carbonn Climate Registry (cCR) is the world´s leading reporting platform to enhance transparency, accountability and credibility of climate action of local and subnational governments. It is designated as the central repository of the Compact of Mayors launched at the Climate Summit 2014.

What our Mayors say

"Today’s announcements – the Compact of Mayors, its standardized reporting process and public data portal carbonn Climate Registry, came out of an unprecedented collaboration among city networks."
