Biodiversity Beyond National Jurisdiction Bill

Roz Savage Excerpts

Consideration of Lords amendments
Monday 2nd February 2026 Commons Chamber

[Dr Roz Savage (South Cotswolds) (LD)]

The Liberal Democrats strongly welcome the Bill, and it is wonderful to hear support for it on both sides of the House.

The global ocean treaty is one of the most significant environmental agreements of our time. It is currently the world’s only viable pathway towards meeting the global 30 by 30 target of protecting at least 30% of the world’s oceans by 2030. The scale of the challenge is monumental. Right now, less than 1% of the high seas is fully protected—less than one penny in the pound of the global ocean. That is the gap that the treaty begins to close.

The ocean underpins everything. It feeds billions of people, absorbs about a quarter of global carbon emissions, regulates our weather and supports livelihoods across the world. However, it is under extraordinary and growing pressure from overfishing, plastic pollution and climate change. I have seen those pressures at first hand. Rowing solo across three oceans, I saw both the beauty of the high seas and the damage that we are doing to them. Out there, beyond national borders, the ocean can also feel beyond human laws. The treaty is about bringing rules, responsibility and stewardship to those waters. It also discharges one of the commitments made to me by the Government during discussions about my private Member’s Bill, the Climate and Nature Bill, and for that I thank them.

While we Liberal Democrats welcome the Bill, we regret the delay. The UK helped to negotiate this agreement, and it would have been fitting had we been among the first to ratify it rather than trailing behind. I thank the campaigners who have kept up the pressure, and the colleagues throughout my party who have long championed ocean protection. They include my hon. Friend the Member for Bath (Wera Hobhouse), who has consistently made the case for stronger high seas governance, as has my hon. Friend the Member for South Cambridgeshire (Pippa Heylings).

[Mike Martin (Tunbridge Wells) (LD)]

Like my hon. Friend, I have spent a fair amount of time on the ocean —not rowing but sailing. When sailing across oceans in a small boat, one cannot help but see the seas of plastic, whether left by fishermen or simply thrown overboard, that are carried on currents. Does my hon. Friend think the treaty goes far enough to tackle the scourge of plastic pollution in our oceans?

[Dr Savage]

I thank my hon. and gallant Friend for his intervention. The treaty does not yet go far enough on plastic pollution, and I hope that the countries of the world will bring their best endeavours to achieving an international agreement in that regard. So far, sadly, those negotiations have not succeeded.

I also want to recognise the serious, constructive work of our Liberal Democrat peers. They chose not to delay ratification, but they worked hard to strengthen the Bill. Lord Teverson pressed Ministers on enforcement gaps, flags of convenience, illegal fishing and human rights at sea, reminding us that the high seas cannot be a legal vacuum for either nature or people, and Baroness Miller of Chilthorne Domer pushed strongly on plastic pollution, especially the plastic pellets that now turn up throughout the marine food chain. Those issues have not gone away, and they now form the implementation agenda.

As Lord Teverson observed during the debates in the other place, this may be one of the last major environmental agreements that we see from the United Nations for some time, given this era in which respect for international law appears to be under strain in a way that we have not seen for many decades. That makes the treaty not just important but precious. We are under a moral and existential obligation to make it work. This ratification must be the start, not the finish. If the UK wants to lead, the Government should aim to arrive at the first Conference of the Parties with a clear plan for implementation, and I suggest that the plan should include the publication of a proper implementation road map including timelines, responsibilities and funding, so that delivery does not drift.

We should back our world-leading scientific institutions, such as the National Oceanography Centre, the British Antarctic Survey and the Centre for Environment, Fisheries and Aquaculture Science. They should be fully supported to provide the evidence, training and technology transfers on which this treaty depends. We should strengthen enforcement using our satellite-monitoring capability and our experience in monitoring vast protected areas in the overseas territories. As a priority, we should get our own maritime house in order. We cannot in good conscience call for protection overseas while allowing destructive practices like bottom-trawling in our own MPAs. Credibility must start at home.

At a time when multilateral co-operation often feels fragile, this treaty shows what is still possible when countries work together to protect the global commons. The Liberal Democrats will support this Bill, but future generations will not judge us on whether we ratified the treaty; they will judge us on whether the oceans are healthier because we did something. Let us match warm words with hard action, and show that Britain still leads when it matters, not just by signing agreements but by protecting the blue parts of our planet, which give us food to eat and oxygen to breathe. To quote Sir David Attenborough, who turns 100 this coming May:

“If we save the sea, we save our world.”

[Sarah Champion (Rotherham) (Lab)]

As chair of the all-party parliamentary group for the ocean, I am delighted to see the Bill’s swift passage through Parliament, and I look forward to its full ratification, but I have some specific questions for the Minister. Can she outline the timeline for the next steps to ensure ratification? Specifically, will it happen ahead of the first ocean COP, expected later this year? If the Minister is unable to give that detail today, would she be willing to meet the APPG for the ocean to discuss the timeline, particularly given that we are now five years away from our 30 by 30 commitment?

I note that the noble Baroness, Lady Boycott, tabled an amendment in the other place that would have ensured that the “polluter pays” and precautionary principles, alongside other principles in the Environment Act 2021, must be applied by UK authorities when they exercised powers or duties under this Bill relating to the high seas. As that amendment was not passed, there are concerns across the ocean sector that there is no statutory requirement in the Bill to extend those environmental principles beyond the UK’s territorial or domestic jurisdiction. Can the Minister comment on that? Will she also offer assurances that, when representatives of the Government or public authorities act under the Bill in relation to the high seas, they will apply the UK’s existing environmental principles so that we do have that coverage?
