A growing family of Climate Action Weeks
London Climate Action Week has inspired a global movement.
What began in London — now the world's largest climate gathering outside the UN's annual COP summits — has sparked a growing network of Climate Action Weeks around the world, each convening local leaders, business, finance and communities to turn ambition into action.
One movement, many cities
Each Climate Action Week is locally led but globally connected — sharing the model, the momentum and the lessons.
London Climate Action Week
The original and the world's largest climate gathering outside the UN COP summits. Each June, LCAW convenes policymakers, business, finance, researchers and communities across London — in 2026, charting the Road to COP31 in Antalya.
