London Climate Action Week (LCAW) 2025 runs from 21 to 29 June 2025, mobilizing London’s unparalleled ecosystem of climate and non-climate organisations to accelerate global climate action while reinforcing London’s role as a climate leader . Now in its 7th year, LCAW is Europe’s largest city-wide climate festival, drawing over 45,000 attendees annually to hundreds of events, both in-person and virtual, across the city and beyond .
What Is London Climate Action Week?
Founded in 2019 by E3G (Third Generation Environmentalism Limited), LCAW provides a brand and platform under which hundreds of organisations, communities, and individuals host climate-focused activities. The official site describes LCAW as harnessing “the unique power of London for global and local climate action.” Through panel discussions, workshops, exhibitions, and grassroots events, it fosters collaboration on solutions ranging from policy innovation to community resilience and green finance .
Why It Matters
Cities both suffer from and can solve climate challenges. London Climate Action Week highlights the role of urban centres in driving systemic change. As climate impacts intensify globally, cross-sector collaboration is crucial. LCAW convenes policymakers, businesses, NGOs, researchers, creatives, and citizens to exchange ideas, scale pilots, and influence decision-making. In doing so, it underscores that local action in a global city can ripple outward, inspiring other metros worldwide .
Key Themes and Focus Areas
Each year features evolving priorities reflecting urgent challenges and opportunities. For 2025, key themes include:
Climate Finance & Green Investment: Mobilising capital for adaptation and clean energy, closing finance gaps, and aligning investors with Paris goals .
Nature-Based Solutions: Urban greening, biodiversity corridors, and ecosystem restoration in and around London to enhance resilience and wellbeing .
Energy Transition & Innovation: Scaling renewables, improving grid flexibility, and integrating digitalisation (e.g., smart grids, AI for efficiency) while phasing out fossil fuels responsibly .
Health and Wellbeing: Exploring links between climate and public health, from air quality improvements to mental health support in a changing environment .
Just Transition & Equity: Ensuring low-carbon pathways are fair, protecting vulnerable communities, and creating green jobs accessible to all demographics .
