UK Ratifies Groundbreaking Treaty to Enhance Global Ocean Protection

The United Kingdom has taken a significant step in international conservation efforts by ratifying the Biodiversity Beyond National Jurisdiction Agreement (BBNJ Agreement), commonly referred to as the High Seas Treaty. This landmark agreement aims to enhance the protection of marine biodiversity in areas that fall outside national jurisdiction, which encompass nearly two-thirds of the world’s oceans.

Strengthening Global Marine Conservation

With the ratification, the UK joins a growing coalition of countries committed to safeguarding the vital ecosystems of the high seas. This agreement establishes, for the first time, a legal framework to create marine protected areas in these international waters, which is crucial for preserving vulnerable habitats and species for future generations.

The Foreign Secretary has completed the necessary formalities to ratify the BBNJ Agreement, signing the required documents that will be officially submitted to the United Nations in New York. This action marks a vital milestone in the UK’s efforts to implement the agreement it helped shape during over a decade of negotiations.

Minister Malhotra, Parliamentary Under-Secretary of State at the Foreign, Commonwealth and Development Office, commented on the importance of the ocean as a shared resource that underpins livelihoods, food security, and biodiversity. He expressed that by ratifying the BBNJ Agreement, the UK is converting international ambition into tangible action to protect marine ecosystems.

A Commitment to Future Generations

Marine Minister Emma Hardy has long viewed the ocean as one of the planet’s most valuable assets, underscoring its vital role in supporting nature, communities, and climate stability. Reflecting on her announcement at the UN Ocean Conference last year, Hardy emphasised that the UK’s commitment to ratifying the BBNJ Agreement was aimed at driving meaningful change. She expressed pride in the UK’s ratification of this significant agreement, noting that it provides essential tools for establishing marine protected areas beyond national jurisdictions.

The BBNJ Agreement aligns with the UK’s ambition to protect 30% of the world’s oceans by 2030, recognising the ocean as a key source of food and oxygen and a critical regulator of the global climate. By facilitating sustainable management of marine resources, the agreement supports international efforts to combat biodiversity loss.

Promoting Fairness in Marine Resource Management

In addition to bolstering protections for marine biodiversity, the BBNJ Agreement also establishes guidelines for the equitable sharing of benefits derived from marine genetic resources. These resources hold substantial potential for applications in medicine, biotechnology, agriculture, and scientific research, ensuring that the benefits of the ocean’s bounty are shared fairly among nations.

The agreement also contributes to the implementation of the Kunming-Montreal Global Biodiversity Framework, which includes a global commitment to protect 30% of the world’s land and oceans by 2030. Furthermore, it reinforces the UN Convention on the Law of the Sea, establishing a solid foundation for international governance of oceanic resources.

Looking Ahead: Key Dates and Future Steps

The BBNJ Agreement was officially adopted by UN member states in 2023 after extensive negotiations spanning over a decade. It is set to enter into force in January 2026, with the inaugural Conference of Parties scheduled for January 2027. The legislative measures required for ratification, including the Biodiversity Beyond National Jurisdiction Act 2026, received Royal Assent on 12 February 2026, enabling the UK to complete its ratification process on 10 July at 14:15 BST.
