London Climate Action Week (LCAW) is one of the world’s largest independent climate events, bringing together policymakers, businesses, researchers, community groups, and civil society to advance climate action.
Now in its eighth year, LCAW convenes more than 75,000 participants across over 1,000 events throughout London each June. The week serves as a key gathering point between UN climate conferences, fostering collaboration, sharing solutions, and driving progress on climate goals at local, national, and global levels.
