UN high seas treaty enters into force, opening a new era of ocean governance
The UN high seas treaty entered into force in 2024, marking the first time in history that the open ocean has received legal protection. The BBNJ Agreement extends international environmental law to the roughly 64% of ocean lying outside any country’s territorial waters. For the first time, the international community has tools to designate marine protected areas, require environmental impact assessments, and share profits from deep-sea genetic resources with developing nations. The treaty is considered essential to achieving the global 30×30 goal of protecting 30% of the ocean by 2030.
