81 Nations Solidify UN High Seas Treaty 2026: A Lifeline for Global Oceans

Two-thirds of the world's oceans are finally getting a legal shield. The landmark UN High Seas Treaty is set to enter into force this Saturday, January 17, 2026. This comes after 81 governments took the decisive step of embedding the agreement into their national laws, marking a turning point for marine biodiversity.

Why the UN High Seas Treaty 2026 is a Milestone for Marine Life

The agreement, officially known as BBNJ, aims to protect the vast, interconnected world of the high seas—home to as many as 10 million different species. Since its adoption in June 2023, a total of 148 countries have signed on, representing more than three-quarters of UN member states.

Ratifying nations include vulnerable island states like Palau and the Maldives, alongside global economic powerhouses such as China, Japan, and Germany. The treaty sets binding rules to conserve biodiversity, share scientific benefits fairly, and create protected marine areas.

US Policy Shift Under the Trump Administration

Despite the global momentum, several key players remain on the sidelines. The United States, India, and Russia have yet to ratify the deal. This is particularly notable in the US, where President Donald Trump is steering the country away from international environmental conventions.

While the High Seas Treaty wasn't on the list of 66 organizations Trump plans to exit, his administration's support for deep-sea mining and offshore drilling stands in stark contrast to the treaty's goals. Non-ratifying nations aren't legally bound but are expected to refrain from activities that undermine the treaty.
