Biodiversity Beyond National Jurisdiction Bill

Carla Denyer Excerpts

2nd reading
Thursday 16th October 2025 Commons Chamber

[Emma Hardy]

I can offer the hon. Gentleman that reassurance. That is an important point well made.

The BBNJ marks an historic breakthrough. It is a multilateral treaty adopted under the United Nations convention on the law of the sea that is designed to ensure the conservation and sustainable use of marine biological diversity in areas beyond national jurisdiction. The agreement delivers on four critical fronts. First, it established new obligations to share the benefits arising from research into and the use of marine genetic resources from these ocean areas. Secondly, it created a mechanism to establish area-based management tools, including marine protected areas, which was an essential step to safeguard fragile ecosystems.

[Carla Denyer (Bristol Central) (Green)]

It is great that the UK is finally ratifying the treaty, and it is also great to hear the Minister talk about the benefits of marine protected areas, but if the Bill is to signify a new and invigorated Government focus on protecting our precious marine environment, does she not agree that the terrible, destructive fishing practice of bottom trawling obliterates vital habitats on our seabed? It makes a mockery of the entire term “marine protected area” that the UK Government have ignored the Environmental Audit Committee’s advice to ban bottom trawling from our own marine protected areas.

[Emma Hardy]

Of course, domestic marine protected areas are not within the remit of the Bill because we are talking about areas beyond national jurisdiction. What I can say is that the UK Government have introduced a consultation looking at banning bottom trawling in 41 of our marine protected areas. That consultation is out now. We are showing our commitment to oceans on not only an international scale but a national scale.

Thirdly, the agreement strengthens the framework for environmental impact assessments by building on the provisions of the UN convention on the law of the sea to ensure that new activities in these areas are sustainable and responsible.

Fourthly, it reinforces capacity building for developing states and promotes broader technological transfer. The journey to the agreement started with an ad hoc informal working group in 2006, before it progressed to a preparatory commission that worked through 2016 and 2017 and culminated in a formal inter-Government conference that negotiated the text between 2018 and 2023.

The UK has already played a leading role in shaping the agreement over the course of more than a decade of negotiations. In September 2023, we were one of the first countries to sign the agreement when it opened for signature at the UN, and today, through the Bill, the UK takes a major step towards ratification.

I will now outline the structure of the Bill, which is divided into five parts. Parts 2, 3 and 4 are designed to correspond and give effect to the three core sections of the BBNJ agreement relating to marine genetic resources, area-based management tools and environmental impact assessments.
