carbonn Climate Registry

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."

Mayor Park Won-soon of Seoul, South Korea and a leader in ICLEI's Mayors network

"Via the new Compact, carbonn will reach out to a wider circle of governments to scale-up GHG emission reduction targets, increase focus on climate risks and adaptation plans and harmonize climate data with existing national, regional, global city reporting platforms."

Jürgen Nimptsch, Mayor of Bonn, Germany and host of carbonn and the ICLEI World Secretariat
