Welcome to the

BBNJ SYMPOSIUM SERIES

Advancing the BBNJ Agreement: A Global Symposium Series
Following its first iteration in October 2023 (Edinburgh, UK) and the second iteration in February 2025 (Singapore), we are happy to announce that the event series will continue with the third BBNJ Symposium in March 2026 in Rio de Janeiro, Brazil!

Since the BBNJ Agreement opened for signature in September 2023, the international community has been working towards the early entry into force of the Agreement. As of June 2025, 51 countries have ratified the Agreement, meaning we are close to achieving the 60 ratifications required for the Agreement to enter into force.

As momentum builds toward the BBNJ Agreement’s early ratification and effective implementation, this series of international symposia has been convened to foster dialogue, share expertise, and support state and stakeholder readiness. From Edinburgh to Singapore and beyond, we will continue to provide more details as they become available.
