Through collaboration on the OPCC, which is led by WWF, ICLEI aims to encourage the reporting of climate related data from local governments around the globe, and to improve the quality of the reported data.

In partnership with CDP, ICLEI provides CDP and ICLEI’s unified reporting system for the report of the data of OPCC participating cities.

ICLEI supports cities by checking their submitted data and by providing guidance. The OPCC acts as vehicle to raise ambition towards climate action globally, as well as to showcase the commitment from local and regional governments.
