Founded in 2019, London Climate Action Week (21-29 June) is now the largest independent climate change event in Europe – and organisers are preparing for 2025 to be the biggest and best edition yet.

Now firmly established as a major feature in the global climate calendar, the event will be a key moment in the 2025 year of delivery and ambition.

This year’s main programme will feature key debates across finance, insurance, resilience, health, nature, geopolitics, energy and governance.

A strong and varied stakeholder-led programme will feature a set of flagship events, alongside wider business, community and cultural initiatives.

London’s climate cluster

London has the largest concentration of climate-focused organisations in the world, and London Climate Action Week (LCAW) has grown to become the flagship moment for London to become a platform for global debate.

The event convenes diverse sectors to deliver groundbreaking initiatives that 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.

The goal is to harness the capital’s power to catalyse global and local climate action.

Climate solutions

The annual festival, established in partnership with the Mayor of London and hosted by leading climate think tank E3G, brings together world-leading climate professionals and communities, all seeking and sharing practical solutions to climate change.

The official LCAW 2025 opening reception will take place 18:30-20:30 on 23 June, hosted by the LCAW Secretariat in partnership with Wellcome.

The event will be opened by Nick Mabey, founder and chair of London Climate Action Week, and will feature contributions from government leaders from London, the UK and Brazil, alongside sponsors.

Making connections

Some of the main events for LCAW 2025 include Blue Earth Forum, Reset Connect, Climate Innovation Forum, Net Zero Delivery Summit and the P.E.A. Awards.

At Blue Earth Forum (24 and 26 June), impact investment will meet breakthrough innovation in a two-day gathering designed to accelerate funding into business solutions.

The Forum will unite more than 300 investors and 40 pioneering businesses with a curated network of business leaders, entrepreneurs and strategic partners focused on building a regenerative future.

Reset Connect London (24-25 June) is an award-winning sustainability and net zero event that will take place at Excel London.

Sustainability leaders, innovators and decision-makers will come together to drive impactful change.

Over five main stages, 400 expert speakers will deliver powerful keynote addresses, thought-provoking panel discussions and engaging presentations.

Eight interactive hubs, located throughout the exhibition floor, will provide a unique space for guests to engage directly with innovative solutions providers, technologies and pioneering startups.

Across the exhibition floor a community of 7,500 attendees, representing diverse sectors such as finance, energy, retail, manufacturing and government, will get space and time to connect, collaborate and network.

Celebrating climate action

Returning for the seventh year, the Climate Innovation Forum (25-26 June), organised by Climate Action, will bring together over 2,000 business leaders, policymakers, investors and civil society representatives to accelerate the speed and scale of our collective efforts in driving climate action.

The Forum will focus on translating promises into tangible actions midway between COPs, harnessing the power of London as a leading global climate hub.

This high-level event champions the role of the real economy in delivering the transition; it serves as a platform for sharing the brave leadership, innovative solutions and radical collaborations needed to bridge the gaps in implementation, investment and scaling-up of innovation.

Marking the crucial halfway point between COP summits, the Net Zero Delivery Summit (23 June) is a high-impact moment to accelerate climate ambition.

It is where leaders in finance, policy and sustainability come together to drive progress beyond pledges.

On 26 June the P.E.A. (People. Environment. Achievement.) Awards, in association with OMMM, will honour the individuals and teams behind the products, services and businesses that are changing the face of our planet.

The UK’s leading climate and sustainability awards, now in their 15th year, identify the green heroes who are taking matters into their own hands and providing inspiring alternatives to business as usual.

These sustainability pioneers, in sectors ranging from finance and energy to music and art, will be recognised and celebrated at a green-carpet event at Ladbroke Hall.
