19 September 2025. Following the deposit of ratification instruments by four new countries this week at the United Nations–Sri Lanka, St. Vincent and the Grenadines, Sierra Leone and Morocco- the High Seas Treaty has reached the milestone of 60 state ratifications needed to trigger its entry into force. Formally known as the Agreement under the United Nations Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction (or BBNJ Agreement), the Treaty will become legally effective 120 days from today (17 January 2026).
“This historic moment is the culmination of years of dedication and global diplomacy by governments and stakeholders” said Rebecca Hubbard, Director of the High Seas Alliance. “The High Seas Treaty is a powerful testament to multilateralism- showing what the world can achieve when we come together for the common good for our ocean, which covers more than 70% of the planet. Today marks an important step when promises start becoming action.”
