Project Manager Climate Action Secretariat

Project Manager, London Climate Action Week (LCAW) Secretariat, London

London Climate Action Week (LCAW) harnesses the unique power of London to accelerate global and local climate action. Founded in 2019 by E3G in partnership with the Mayor of London, LCAW has become one of the largest independent climate festivals globally and a key moment in the international climate calendar. LCAW operates as an independent public‑good platform, guided by the principles of impact, inclusivity, openness, and radical collaboration.

It is now transitioning to a year‑round organisation, anchored by its annual festival in June and supported by a dedicated Secretariat.
