London Climate Action Week 2026
Sun 28-Jun-2026
London Climate Action Week (LCAW) harnesses the unique power of London for global and local climate action.
It mobilises London’s unparalleled ecosystem of climate and non-climate organisations to accelerate global climate action and supports action in London to ensure it acts as a global climate leader.
The week aims to demonstrate the whole of society engagement needed to support the delivery of decarbonisation and resilience as well as stimulate other global cities to host similar events.
