Returning this year with a bigger format, new global brand partnerships including headline partner, 1% for the Planet, and a relentless focus on solutions, the Forum tripled in size and ambition, cementing London’s place as the new global capital for climate-led business. 

“We’re building a fairer, greener London and events like Blue Earth are central to that. Innovation, investment and action are on tap here. London is the place to be.” Mete Coban, Deputy Mayor for Business, London 

The ultimate climate ecosystem built for action

Over two action packed days and networking nights, Blue Earth Forum convened a powerful cross-section of the climate ecosystem: early-stage startups, institutional investors, major brands & business, policy leaders, media, and movement-makers. It wasn’t just about talking. It was about what happens next.

650 guests attended Blue Earth Forum’s Opening Reception before diving into two full days of bold discussions and business matchmaking. With DJs, super fuelled food, climate-conscious cocktails, and late-night connections, it was proof that purpose can be powerful and joyful.

A brand new Blue Earth Sessions series served a rich menu of inspirational and educational content. Business leaders as diverse as eBay, Klarna, Vodafone, Ovo, Ecologi, Greenvolt and Mastercard joined panel guests, to explore the sustainable future of food, energy, climate technology, materials and transport. Interspersed with experts sharing insights on deal flow, successful exits and net zero measures. The new Sessions sold out rapidly..

Day 1 included the launch of Destination Electric from OVO, unpacking the rapid shift to electric living; Circular by Nature with Woolmark, exploring regenerative materials and innovation in textiles; and Rewriting the Energy Playbook with Greenvolt, focused on decentralised power systems.

Meanwhile, HSBC Innovation Banking and BAE HQ hosted roundtables to explore how to unlock cross-sector innovation and fast-track capital into climate tech.

UnlockVC ignited Day 2 with a data packed  investor roundtable whilst  Investing in Nature: What Returns Can Investors Expect? brought together leaders from Ecologi, Triodos, Howden Group, and Oxygen Conservation to explore the case for investing in natural capital.

Impact investors met startups to supercharge solutions

Across both days, 50 handpicked startups pitched their solutions live, representing sectors from clean mobility to AI-powered climate insights. 

Investor panels featured major players including Energy Impact Partners, JamJar Investments, EKA Ventures, Triodos, Active Partners, Joelson, Box Fund, Foresight Group, Innovate UK, Carbon13, and many more.

“We’ve seen ambition on a whole new level. From the size of the Forum to the quality of conversations happening in every corner, it’s clear the movement is accelerating.” Guy Hayler, COO, Blue Earth Ventures

From one-on-one investor meetings and high-stakes pitches to off-stage conversations in the breakout zones, the Forum was designed for momentum. And it delivered!

“The conversation has finally shifted – from awareness to real-world solutions. We’re proud to provide a platform for the world’s most exciting innovations in climate and impact.” Will Hayler, CEO, Blue Earth

Blue Earth Forum 2025 showed what’s possible when business, investment, and innovation align and Blue Earth Summit between 15 and 17 October will take connections to a whole new level. Building bridges between capital and ideas. The Summit creates space for truth-telling, solution-building, and celebration. And above all, the momentum will continue!
