Overview of the High Seas Treaty
On January 17, 2026, the High Seas Treaty, formally known as the Agreement on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction (BBNJ), officially came into effect. This treaty establishes the first legally binding framework to protect marine biodiversity in international waters, which comprise nearly two-thirds of the world's oceans. The treaty was finalized in March 2023 after 15 years of negotiations and reached the threshold of 60 ratifications by September 2025, with over 80 countries, including China, Brazil, and Japan, now having ratified it.
Key Obligations and Goals
The treaty mandates that ratifying countries conduct environmental assessments for activities impacting ocean ecology and promotes international cooperation on marine science and technology. Countries are also required to share benefits derived from marine genetic resources. A significant goal is to protect 30% of the world's oceans by 2030, a target that necessitates the establishment of over 190,000 marine protected areas. Currently, only about 8% of the oceans are under formal protection.
Criticism and Challenges
Despite the treaty's ambitious framework, critics highlight significant challenges. Environmentalists express concern that the treaty does not address deep-sea mining, which poses a considerable threat to marine ecosystems. Adam McCarthy, a co-chair of the treaty's preparatory committee, acknowledged that while the treaty is comprehensive, it does not extend to seabed mining, which falls under the jurisdiction of the International Seabed Authority.
Additionally, the UK has faced criticism for its slow ratification process. Environmental charities have urged the UK government to expedite the ratification bill, which is still pending in Parliament, to ensure the country can participate in upcoming international ocean governance discussions.
Global Response and Cultural Actions
In celebration of the treaty's entry into force, artists and activists worldwide have created murals and public artworks to raise awareness about ocean protection. These initiatives, coordinated by Greenpeace, span 13 countries across five continents, transforming public spaces into visual representations of the urgent need for marine conservation. For instance, a mural in St Leonards-on-Sea, UK, features a message in a bottle directed at the UK government, symbolizing both hope and urgency for legislative action.
Official Statements and Responses
Rebecca Hubbard, director of the High Seas Alliance, emphasized the importance of universal ratification for the treaty's effectiveness, stating, "It's critical for its implementation and for it to be as effective as possible for us to achieve global or universal ratification." Meanwhile, Chris Thorne, senior oceans campaigner at Greenpeace UK, remarked, “The Oceans Treaty enables governments to protect large areas of the high seas for the first time... But while communities around the world are celebrating, the UK government is holding us back.”
What's Next
The first Conference of the Parties, required to occur within one year of the treaty's entry into force, will address key operational details, including the establishment of marine protected areas. Countries are expected to begin proposing protected areas immediately, with potential sites already identified, such as the Sargasso Sea and the Emperor Seamounts.
The High Seas Treaty marks a pivotal moment in global ocean governance, offering a framework for sustainable management and protection of marine biodiversity. However, the success of this treaty hinges on swift and decisive action from governments worldwide.
