Officially known as the Agreement on the Conservation and Sustainable Use of Marine Biodiversity beyond National Jurisdictions (BBNJ), it was approved on June 19, 2023, after a long process of negotiations between United Nations member countries dating back to 2015. In that year, a Preparatory Committee recommended the development of a text that would serve as a legally binding international instrument under the United Nations Convention on the Law of the Sea (UNCLOS), for the conservation and sustainable use of marine biological diversity in areas beyond national jurisdictions of the ocean (200 miles). Finally, in the fifth period of talks, the Conference approved the BBNJ Agreement by consensus in June 2023.
Importance of the Agreement The agreement outlines the principles for the conservation and sustainable use of all marine biodiversity beyond national boundaries, that is, an area of approximately 190 million square kilometers (km2), half of the ocean surface on the planet which reaches more than 361 million square kilometers. Furthermore, with the entry into force of the BBNJ, the creation of a broad global network of marine protected areas in the high seas is expected, which will promote the commitment to protect 30% of the ocean by 2030, better known as 30×30.
First Steps Once in force, the Preparatory Commission, which has met throughout this year and will hold another meeting in early 2026, will continue working to lay the foundations for the treaty institutions, including the Secretariat, the Scientific and Technical Body and the Committee on Access and Benefit-Sharing, among other subsidiary bodies. The High Seas Treaty will enter into force on January 17, after achieving ratification by 60 countries last September, a document of great importance for monitoring activities outside national jurisdictions, at a time when several actors are scrutinizing the possibility of starting mining on the seabed. This means that this tool will regulate human activities on the high seas, through the development of environmental standards contemplated in the United Nations Convention on the Law of the Sea, equivalent to a “constitution for the oceans.” In addition, the treaty provides for the creation of a Conference of the Parties (COP) and several dependent bodies, an information exchange mechanism and a secretariat, as well as a financing mechanism.
BBNJ Headquarters Chile was the first country to ratify the BBNJ and has requested to host its Secretariat, which would be located in the port city of Valparaíso, as explained to EFE in Athens by the Director of Environment, Climate Change and Oceans of the Chilean Ministry of Foreign Affairs, Julio Cordano. In 2017, the United Nations General Assembly convened an Intergovernmental Conference to analyze the document, followed by periods of annual meetings that were interrupted by the pandemic, between 2019 and 2022.
