More than 450 climate finance leaders were at the high-profile 2025 event, held as part of London Climate Action Week, which marked a significant milestone in efforts to bridge the massive funding gap for climate adaptation and resilience worldwide.

Her Excellency Marina Silva, Minister for Environment and Climate Change in Brazil, opened the summit, followed by a keynote address from Wopke Hoekstra, commissioner for climate, net zero and clean growth at the European Commission.

The summit concluded with a high-level panel featuring Ambassador Andre Correa do Lago, President-Designate of COP30, who looked ahead to the UNFCCC conference in Belem in November 2025. He was joined by Ruth Davis, UK Special Representative for Nature, Sheela Patel, founder of SPARC, and Linda Freiner, chief sustainability officer at Zurich Insurance Group.

The day's key messages started to come together in the closing plenary, where delegates shared the powerful insights and actionable solutions that had emerged.
