Cities Climate Action Summit is the must-attend city, local-government and sub-national event dedicated to discuss how cities around the globe can drive change. Bringing together visionary city leaders, creative policymakers, green finance experts, and cutting-edge technology innovators, our mission is to drive action into solving urban climate challenges.

The Summit takes place across two days in June 2025. The first day will be streamed virtually to allow our world-wide audiences to get involved in the conversation, while the second day will be held in-person in London.
