Description The carbonn Climate Registry (cCR) was launched at the World Mayors Summit on Climate in Mexico City on 21 November 2010 under the name carbonn Climate Registry (cCCR), as the global response of local governments to measurable, reportable and verifiable (MRV) climate action.
Objectives The cCR is a global mechanism developed for local governments by local governments. It enables them to publicly and regularly report their local climate action developments:

- greenhouse gas (GHG) reduction commitments, - emissions inventories - climate mitigation / adaptation actions Expected effect of implementation of targets (direct) (comment)=0.15 Gt CO2e (0.02-0.31 Gt CO2e) expected to be reduced in 2020 (Jaquot,2013). Achieved emission reductions to date (comment)=Potentially high due to extensive coverage. (March 2013, 302 cities from 42 countries, controlling a community GHG emissions of around 1.5 GtCO2e annually) (UNEP, 2013)

Activities Beginning in April 2019, local and regional governments will just need to report once on CDP’s platform and publicly reported data will automatically be shared with ICLEI.

Local and regional governments can give their permission to both ICLEI and CDP to use their publicly reported data and will receive the support of both organizations. We encourage local and regional governments to report publicly as this strengthens subnational data and contributes to transparency and good governance. ICLEI will use this data to inform research and analysis activities and to represent local and regional governments on the global stage through high level political advocacy work. CDP will use this data to produce analytics and snapshot reports for local and regional governments, allowing them to track their progress and benchmark themselves against their peers. Reporting will remain free, and the publicly reported data will be freely available online through CDP’s Open Data Portal and on Both organizations will continue supporting the Global Covenant of Mayors for Climate & Energy (GCoM), the largest global coalition of cities committed to climate leadership. The unified reporting system already integrates GCoM’s Common Reporting Framework, the new global framework for reporting city greenhouse gas inventories, risk and vulnerability assessments and climate action plans. GCoM’s new standards reflect the reporting that cities have already been doing and allows harmonization of city data across the globe. CDP and ICLEI’s unified reporting system will also continue supporting the Under2 Coalition for subnational states and regions.
