OSPAR is celebrating a landmark moment for ocean governance: the entry into force of the High Seas Treaty. Following the 60th ratification in September 2025, 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 (BBNJ Agreement) became legally effective. This historic achievement marks the first time the global community has a legally binding framework to protect biodiversity in areas beyond national jurisdiction.

The Treaty is vital for the health of the planet. Covering nearly two-thirds of the world’s ocean, the High Seas play a critical role in regulating climate and sustaining marine life. The BBNJ Agreement provides powerful new tools, including the ability to establish marine protected areas in international waters and to require environmental impact assessments for activities that may harm ocean ecosystems. It also strengthens equity by supporting developing countries through capacity building, technology transfer, and fair access to the benefits of marine genetic resources.

For OSPAR, the Treaty is especially significant because it increases the incentive, and provides a framework, for cooperation between the International Competent Authorities managing activities in areas beyond national jurisdiction with the overall aim of sustainable use for the common good. All OSPAR Contracting Parties have signed the Agreement, with several already ratifying, underscoring the region’s strong commitment to international ocean protection. The Treaty will be central to achieving global biodiversity and climate goals, including the Kunming–Montreal Global Biodiversity Framework target to protect 30% of the ocean by 2030. Preparations are already underway for the first Conference of the Parties, expected in 2026, and for the development of ambitious High Seas marine protected area proposals.

As we mark this milestone, we also pause to acknowledge the sad passing of Kristina Gjerde, a tireless advocate for High Seas conservation and a driving force behind the vision that ultimately became the BBNJ Agreement. Her dedication, expertise, and leadership have left a lasting legacy for ocean governance worldwide, and her contributions will continue to shape efforts to protect the ocean for generations to come.
