Protecting Ocean Life on the High Seas

The high seas make up about two thirds of the world’s ocean, covering the vast expanses beyond the jurisdiction of any country.

In June 2023, with extensive support from The Pew Charitable Trusts, the United Nations adopted a treaty establishing a legal framework to create a network of high seas marine protected areas – the equivalent of international parks at sea – and put in place standards, guidelines and a consistent process for assessing the environmental impacts of new high seas activities.

To help ensure that the ocean continues to support thriving biodiversity, benefit humankind and maintain resilience against threats such as climate change and overfishing, Pew is partnering with governments, scientists, regional ocean management organizations and other key stakeholder groups to enable the rapid and effective implementation of the treaty once it enters into force. Pew’s focus in this collaborative effort is on establishing a path towards the creation of the first generation of high seas marine protected areas by 2030.

High Seas Treaty Must Reflect Critical Role of Fish in Ecosystems

Members of the United Nations are negotiating a treaty that would enable the conservation and sustainable use of biodiversity in areas beyond national jurisdiction (ABNJ), including the international waters known as the high seas.

Protect the High Seas

The high seas—waters beyond any single country’s jurisdiction—cover more than half our planet’s surface. They are among the most biodiverse locations on Earth, harboring remarkable ecosystems and providing countless benefits for marine life and humanity alike. The problem? Right now, only 1% is protected.
