The annual London Climate Action Week (20-28 June), will bring together 75,000 people from business, policy and finance to scale climate and nature solutions and accelerate implementation.

Background

London Climate Action Week (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, and where the international climate community gathers to build the cooperation for progress and action. This year, the Commonwealth Secretariat will participate in and host multiple LCAW events.
