Starting in 2019, local and regional governments are – for the first time – reporting climate action data through one unified reporting system. They give their permission to both CDP and ICLEI to use their publicly reported data and receive in return the support of both organizations. ICLEI uses this data to inform research and analysis activities focusing on diverse sectors from transport to waste, energy and air quality, and to represent local and regional governments on the global stage through our advocacy work. ICLEI supports local and regional governments to improve the quality of their reporting and provides performance reports to selected cities.
