Historic High Seas Treaty Enters Into Force

January 19, 2026

“Half of the world is beyond national jurisdiction – the blue half that has a disproportionately significant role in maintaining Earth as a planet hospitable for life as we know it. Today, with the entry into force of the High Seas Treaty, marks a significant step in the right direction. Now is the time to take this action and keep going. The ocean is large and resilient, but not too big to fail – and we have an opportunity now to drive impactful ocean protection. Bravo to the High Seas Alliance and all involved for reaching this significant milestone!” – Dr. Sylvia Earle

The High Seas make up nearly half of our blue planet. Beyond national borders, these waters belong to all of us—and they are essential to a living, thriving ocean. For the first time, this landmark UN treaty creates a legal framework to protect biodiversity in the global commons and to ensure the benefits of ocean life are shared more equitably. It is a powerful step toward safeguarding the blue heart of the planet, and a reminder that when nations work together, meaningful ocean protection is possible.
