An open and inclusive platform for action — and a public good — LCAW is one of the world’s largest independent climate events. Now in its eighth edition, it brings together more than 75,000 people across more than 750 events over nine days each June — from community gatherings in every borough to ministerial roundtables in the City of London, from school events to major international conferences. Climate action happening, visibly, across an entire global city. 

LCAW is a key moment in the global climate calendar — where climate action happens between COPs, where the UN Global Climate Action Agenda comes alive in cities and communities, and where the international climate community gathers to build the cooperation for progress and action.
