The Climate Summit for Local Leaders is a Historic Convening of Local Leaders
Fighting Climate Change

On December 4, Anne Hidalgo, Mayor of the City of Paris and Michael R. Bloomberg, the UN Secretary-General’s Special Envoy for Cities and Climate Change – in partnership with the global networks of cities and local governments for climate action – co-hosted the Climate Summit for Local Leaders – the largest global convening of mayors, governors and local leaders focused on climate change.

This historic event coincided with the 21st Conference of Parties (COP21) in Paris, helping to ensure that the voices of local leaders are heard, and city efforts were recognized, during the international negotiation process, in order to reach a universal, legally binding agreement that will enable us to combat climate change effectively.

Major climate initiatives supported by local and subnational governments will be introduced and have a presence at the Summit.


The Summit will highlight and build on the efforts of the Compact of Mayors, a global coalition of mayors and city officials pledging to reduce local greenhouse gas emissions and track their progress transparently.


The Summit ensures city voices are heard at COP21, and that their efforts are reflected in the treaty negotiations.
