From 21-29 June 2025, London will, for the seventh year, be transformed into a hub of action and inspiration as it plays host to Europe’s largest independent climate change event.
London Climate Action Week (LCAW) is the largest city-wide climate festival in Europe and a key moment in the global climate calendar.
The annual festival, established in partnership with the Mayor of London and hosted by leading climate think tank E3G, unites world -leading climate professionals with communities to find practical solutions to climate change.
Designed around the principles of impact, inclusivity, openness and radical collaboration, LCAW is a forum for global conversations on the politics and practicalities of climate action and cooperation.
The goal is to shape climate action and foster diplomacy in the run-up to each annual COP (UNFCCC Conference of the Parties), as climate change continues to influence geopolitics, trade, security and bilateral relations.
London has the largest concentration of climate-focused organisations in the world; LCAW harnesses the capital’s unique power to inspire global and local action for the climate, so the city can play an increasingly important role in leading and supporting the global climate transition.
LCAW generates synergies and fosters collaboration across London’s unique ecosystem of globally active organisations, which are addressing climate change through their work in sectors ranging from commerce to science, academia and non-profit institutions.
Since 2019, LCAW has mobilised this unparalleled ecosystem of climate actors in unity with London’s institutions, communities and sectors to accelerate global and local climate action.
The festival has grown to become a flagship moment for London to become a platform for global debate, convene diverse sectors to deliver groundbreaking initiatives and actions, showcase the depth and strength of London’s unique ‘climate cluster’ and engage people and communities in London to drive green, fair climate action in their city.
It also serves as an annual moment to mark progress and engage Londoners in their city’s net zero transition.
2024 was the biggest LCAW to date, with more than 350 events and 45,000 attendees.
The hope is for 2025 to be even bigger, with activity to build climate ambition on the road to COP30 through events that will help to shape the cooperation, politics, diplomacy and finance needed to deliver a 1.5ºC-aligned outcome.
A theme for 2025 is how to finance an inclusive and resilient climate transition by reforming financial markets and scaling up investment in net zero, resilience, nature and just transitions.
Events will also look at ways to deliver a net zero and resilient London and UK, with a focus on assessing and accelerating progress towards current goals in London and the UK, and shaping how London will support greater climate action in other regions outside the city.
The festival will also explore how to inspire whole-of-society climate action, with a focus on mobilising key networks in law, professions, education, health, fashion, arts and culture.
LCAW is now recognised as one of the major moments in the global climate calendar and a leading venue for climate diplomacy, finance, business, city and professional action.
It has already inspired and helped to create seven similar climate action weeks around the world, from Shanghai to Sydney.
Through this network, LCAW is shaping the frontier of global climate action – and everyone’s invited to take part.
