Subnational and Local Authorities

Cities Biodiversity Summit

The Summit for Subnational Governments and Cities, also referred to as the City Biodiversity Summit, is the high-level convening of local and subnational governments at the biodiversity COP. It is co-hosted by ICLEI – Local Governments for Sustainability, through its Cities Biodiversity Center, together with the CBD Secretariat, the COP host city and country, Regions4 and other partners.

Held as an official parallel event at each biodiversity COP since 2008, the Summit gives governors, mayors and subnational leaders a platform to engage directly with national delegations, showcase territorial-scale biodiversity action, and feed outcomes into the negotiations. Since the first Summit, at least one official COP decision dedicated to local and subnational governments has emerged from each Summit's negotiations.
