About the carbonn® Climate Registry

The carbonn® Climate Registry is the leading global reporting platform for cities, towns and regions tackling climate change. It helps local and other subnational governments to track and report on their targets, actions and performance. This platform allows for exchange, learning and benchmarking among its 950+ registered entities while providing data that feeds into global climate negotiations through ICLEI as focal point for the Local Governments and Municipal Authorities constituency.

The carbonn® Climate Registry has grown tremendously since its launch in 2010. With over 600 reporting jurisdictions representing 10 percent of the global population, the Registry sends a powerful signal that cities, towns and regions are rapidly advancing. The release of five years of data at COP21 is an important milestone and a testament to the scale of local action.
