  • ​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.

  • ​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.

  • $90bn in climate dry powder remains as of Q1 2026, after a record fundraising year in 2025.
