The UK government has committed to introducing legislation by the end of 2025 that aims to ratify the High Seas Treaty, a landmark agreement designed to protect marine life on a global scale. Marine Minister Emma Hardy announced this initiative on 10 June 2025, highlighting its significance in reaffirming the UK’s leadership in international climate and biodiversity efforts. The treaty will establish a legal framework for the creation of Marine Protected Areas (MPAs) in international waters, which comprise about two-thirds of the world’s oceans.

The High Seas Treaty, officially called the Biodiversity Beyond National Jurisdiction Treaty, was signed in 2023 but has yet to come into force. For this to happen, it requires ratification by at least 60 countries; currently, 49 have ratified it. This innovative treaty offers the first legally binding mechanism to protect ocean biodiversity, which has been increasingly threatened by overfishing, climate change, and planned activities like deep-sea mining. According to various sources, only 3% of the world’s oceans are currently protected, making the treaty’s implementation crucial for enhancing the resilience of vulnerable marine ecosystems, including species such as sharks, sea turtles, and whales.

Hardy underscored the urgency of this initiative by stating, “Our oceans are dying. Without urgent action, they will be irreversibly destroyed.” The UK’s support for the treaty aligns with broader international efforts, as evidenced by its participation in the United Nations Ocean Conference in Nice, France, where more than 90 countries have reiterated commitment to an ambitious Plastic Pollution Treaty slated for negotiation in Geneva this August.

The conference’s backdrop highlights the dire state of the oceans, with reports indicating that less than 3% are under effective protection, despite their critical role in global biodiversity and climate regulation. The High Seas Treaty specifically mandates environmental impact assessments for commercial activities, ensuring that marine resource management is equitable and sustainable.

In addition to the ratification plans, the UK government is also proposing an expansion of a ban on bottom trawling in its own waters. This ban—which is set to cover an additional 30,000 square kilometres across 41 Marine Protected Areas—aims to prevent damage to delicate marine habitats. This proposal has garnered the attention of prominent conservationists, including naturalist David Attenborough and Prince William, who have advocated for immediate action against harmful fishing practices.

Former US Secretary of State John Kerry echoed these sentiments at the conference, emphasising the crucial moment for global marine conservation. He called for action against harmful practices and underlined the need for leadership in adopting measures that protect invaluable marine ecosystems. Kerry, like others at the conference, acknowledged that the rapid adoption of the High Seas Treaty marks a significant step toward reversing the alarming trend of ocean degradation.

As the world approaches the critical threshold of 60 ratifications, the High Seas Treaty stands as a beacon of hope for marine conservation. Its successful implementation could catalyse a new era of collaborative international efforts aimed at protecting the planet’s oceans, ultimately benefiting both marine life and human wellbeing.
