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.
