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 from West Africa and Brazil, spanning both conservation projects and afforestation projects.

  • ​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.

  • 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.

  • 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.

  • $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.

  • The Earthshot Prize is a global challenge to find, support & celebrate those who turn bold ideas into real solutions to repair our planet.

    Featured within two sessions across Nature & Cities streams - discover the global finalists & winners turning their purpose into action, with impressive results.
