NEW YORK — International ocean governance reached a landmark milestone on Tuesday as the United Nations officially received the required 60th instrument of ratification for the High Seas Treaty, clearing the path for the legally binding agreement to enter into force early next year.
Formally known as the Agreement on Biodiversity Beyond National Jurisdiction (BBNJ), the treaty establishes the first global framework to protect marine life in international waters, which cover nearly two-thirds of the Earth’s oceans. Prior to the agreement, less than one percent of these vast, shared international waters were subject to formal, binding conservation protections, leaving high-seas ecosystems vulnerable to unregulated resource extraction and environmental degradation.
Under the terms of the treaty, signatory nations will gain the legal mechanism to create high-seas marine protected areas, mandate comprehensive environmental impact assessments for industrial activities—including potential deep-sea mining and commercial shipping expansion—and establish rules for the equitable sharing of marine genetic resources. UN officials emphasized that the agreement is crucial for reaching the global target to conserve 30 percent of the world’s lands and oceans by 2030.
While environmental organizations and island states hailed the threshold as a historic victory for global diplomacy, several industrialized nations and maritime industry groups urged caution regarding the treaty’s execution. Representatives from the international shipping sector expressed concerns over potential regulatory overlaps with existing maritime organizations, calling for streamlined compliance protocols to avoid disruption to global trade corridors. Furthermore, major fishing nations have stressed the necessity of maintaining the jurisdiction of established regional fisheries management bodies.
With the 60-nation threshold officially met during the UN General Assembly high-level week, the treaty will formally enter into force in 120 days. Preparations are now underway for the inaugural Conference of the Parties, where delegate nations will convene to elect a secretariat and outline the first proposals for designated marine sanctuaries in international waters.
