The 9th Summit for Subnational Governments and Cities will bring together local and subnational governments, international organisations and partners to strengthen collaboration, scale implementation, mobilise finance and accelerate multilevel action for biodiversity.

Taking place on 24 October 2026 in Yerevan, Armenia, the Summit will build on two decades of collaboration between ICLEI, the CBD Secretariat, Regions4, UNEP and other partners to strengthen the role of cities and regions in global biodiversity action.

Co-hosted by ICLEI, the CBD Secretariat, Regions4, the Government of Armenia and the City of Yerevan, the Summit will explore practical approaches to multilevel governance, policy implementation and financing for nature-positive development.
