UNITED NATIONS — The United Nations announced on Tuesday that the landmark High Seas Treaty has secured its 60th official instrument of ratification, triggering the formal mechanism required for the agreement to enter into legal force. The milestone establishes the first binding international framework dedicated to conserving marine biodiversity in ocean areas beyond national jurisdictions, covering nearly two-thirds of the world’s oceans.
Formally known as the agreement on Biodiversity Beyond National Jurisdiction (BBNJ), the treaty was adopted in 2023 following more than a decade of international negotiations. Under its provisions, member states will now have the legal authority to create large-scale marine protected areas in international waters. These sanctuaries will place strict limits on industrial activity, including commercial fishing, deep-sea resource extraction, and shipping lanes, aimed at preserving delicate deep-ocean ecosystems.
Environmental diplomats hailed the achievement as a critical step toward fulfilling the global commitment to protect 30 percent of the Earth’s lands and oceans by 2030, a goal established under the Kunming-Montreal Global Biodiversity Framework. Prior to this agreement, less than two percent of the high seas benefited from formal conservation management, leaving vast oceanic expanses vulnerable to overexploitation and climate-driven degradation.
Despite the widespread diplomatic consensus, implementation poses complex logistical and political challenges. Concerns remain regarding how enforcement will be monitored in remote international waters, as well as how access to marine genetic resources—often utilized in pharmaceuticals and biotechnology—will be equitably shared between developed and developing nations. Several high-capacity fishing nations have called for clear regulatory boundaries to prevent economic disruption to global food supply chains.
UN officials confirmed that the treaty will officially take effect within 120 days. Delegates are scheduled to meet in Geneva early next year for the inaugural Conference of the Parties (COP1), where member nations will establish the permanent Secretariat, finalize procedural rules for environmental impact assessments, and address funding mechanisms to assist coastal developing nations with compliance and monitoring efforts.
