Official Partner Event of


2026 Summit Sessions

  • This panel will explore the reality investing in, operating and scaling large-scale natural capital projects across the global south. It will combine the perspectives of investors and operators on the ground - on afforestation projects in West Africa and Brazil.

  • ​As governments, investors and businesses respond to the opportunities created by the High Seas Treaty, how can we accelerate investment in ocean resilience and build a sustainable blue economy? This panel discussion will bring together perspectives from ocean governance, biodiversity innovation and conservation finance to explore how science, policy and investment can work together to unlock scalable action for our shared ocean future.

  • Southeast Asia’s energy transition requires far more capital than is currently flowing into the region. This spotlight session introduces FAST-P, Singapore’s blended finance initiative, and how its US$500 million catalytic commitment is designed to mobilise partners and crowd in private capital for Asia’s green and transition infrastructure.

  • Family offices have a unique advantage in impact investing — patient capital, multigenerational thinking, and freedom from institutional constraints. This session brings together family office investors to explore how they deploy capital across nature and cities, how they think about resilience, and what barriers prevent more family offices from investing for impact. Panellists will also share candid advice for founders looking to raise capital from family offices.

  • ​The entry into force of the BBNJ Agreement (also known as the High Seas Treaty) marks a historic moment for global ocean governance, creating new momentum for the conservation and sustainable use of biodiversity beyond national jurisdiction. This keynote will explore what the Treaty means for Commonwealth countries, international cooperation, and the future of ocean resilience and sustainable development.

  • The world's food system faces converging pressures - climate shocks, supply chain fragility, and billions of smallholder farmers operating without adequate infrastructure or support.

    This session brings together Earthshot Prize Finalists tackling food security from multiple angles: solar-powered cold storage, coastal fisheries technology, food fermentation, precision drying, and direct market access for small-scale producers.

    Hear from the founders alongside the investors and champions backing their growth, on what it takes to build and scale climate-positive food solutions - and get them to the people who need them most.

  • Nearly 60% of the world's population lives in cities - and that number is growing.

    This session brings together Earthshot Prize finalists whose solutions are reimagining what urban life can look like. Hear their stories, their breakthroughs, and their vision for cities that work for people and the planet.

  • Creating regenerative places requires more than great projects. We need a shared vision of the outcomes we're trying to achieve, a clear understanding of resilience, innovative mechanisms for finance and risk management, and ways to scale impactful sustainability solutions. UKGBC's work is focused on connecting those pieces, turning insight into tangible action.

  • $90bn in climate dry powder remains as of Q1 2026, after a record fundraising year in 2025. Stretched exit timelines are keeping LP capital locked up longer than expected, making LPs wary of committing fresh capital. Infrastructure funds are playing a different game: yields from mature tech deployment are slow but steady, and they're raising record amounts because of it.
