ICLEI and CDP: Introducing streamlined climate reporting

Providing services for communities, protecting citizens and building better places to live, work and do business are the core priorities of local and regional governments everywhere. Climate action and reporting are vital to achieve these aims. The easier the reporting process, the more time governments have to focus on taking action, on bringing benefits to their citizens and local economies. That’s why ICLEI and CDP are partnering to present one unified process for subnational climate action reporting.

"Using data from over a thousand cities, ICLEI's climate experts deliver critical analyses that can assist national governments in tracking subnational climate action and incorporating these efforts into national planning to curb carbon emissions."
