Biodiversity Beyond National Jurisdiction Bill

Roz Savage Excerpts

Monday 17th November 2025 Commons Chamber

[The Chairman of Ways and Means (Ms Nusrat Ghani)]

I call the Liberal Democrat spokesperson.

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

It is a pleasure to serve under your chairmanship, Ms Ghani. I am honoured to support the passage of this Bill, along with my Liberal Democrat colleagues. It is a real pleasure to see people across the House who have been long-time champions for the ocean. Many people would have liked to have been here tonight, but are forced to be absent by COP30. They will be watching from afar and wishing us well.

I thank the Minister for taking us in detail through the provisions of the Bill, and the shadow Minister, the hon. Member for Romford (Andrew Rosindell), for setting out his amendments. It perhaps falls to me to remind those in the House and beyond of just how significant a step this Bill takes. It may not be enough to save the oceans from their catastrophic decline in health, but it is certainly a big step in the right direction.

The oceans cover two thirds of the planet. The high seas—the areas of the ocean beyond national jurisdictions —make up nearly half the world’s surface and much of its liveable volume. Up until now, they have existed in a legal grey zone, vulnerable to exploitation, and they certainly have been egregiously exploited. The high seas are essential to life not just in the seas, but on dry land, too. With this Bill, the UK finally places itself in a position to uphold the new global agreement to protect ocean biodiversity. It is long overdue and much damage has been done, but it is none the less deeply welcome.

We often speak about forests and land ecosystems, yet the ocean is the Earth’s most powerful driving force, regulating our climate, generating oxygen, absorbing carbon and heat, feeding billions, sustaining cultures and anchoring our weather systems. As anyone who has spent much time out there knows, the ocean’s power is matched only by its fragility. During my crossings of the Atlantic, Pacific and Indian oceans, I came to understand the sea in an intimate way. Alone in a small boat, weeks or months from the nearest coast, you are immersed in the rhythms of the ocean, with its long rolling swells, the astonishing wildlife that appears from the deep, and the immense silence that settles when the wind drops away to nothing. At times, the ocean felt overwhelmingly powerful, and at others unexpectedly tender.

The lessons that I learned on the ocean have stayed with me, especially the lesson that survival depends not on domination, but on partnership. It is not survival of the fittest; it is about the species that fits in best with its surrounding ecosystem. Humans would do well to remember that. That is why I am particularly heartened to see that today we have genuine cross-party alignment. When Parliament chooses collaboration over confrontation, we show what is possible. It echoes the spirit that I felt when I first introduced the Climate and Nature Bill earlier this year, and I give huge credit to my co-sponsors, a genuinely cross-party group of Labour, Conservative, Lib Dem, Green, SNP and Plaid Cymru MPs. That consensus across the House was based on the understanding that long-term environmental policy works only when it transcends party politics, rather than being used as a political football. I am proud that the Climate and Nature Bill campaign contributed to the ratification of this treaty, and I commend the Government on following through on their promise to all the hard-working campaigners.

We must recognise the headwinds internationally and domestically. Some voices are questioning climate ambition, watering down commitments or treating environmental progress as optional. We cannot afford that drift. Climate and ocean policy must be future-proofed against short-term politics. Nature does not bend to electoral cycles.

[Dr Al Pinkerton (Surrey Heath) (LD)]

As my hon. Friend well knows, 94% of the UK’s biodiversity lies within the waters of our overseas territories. Just north of the Falkland Islands is the so-called blue hole, an area of unregulated fishing beyond national jurisdiction. It is an area where trackers are turned off and illegal fishing takes place. Does she agree that the ratification of the BBNJ agreement may provide the opportunity—the common cause—to tackle intractable geopolitical issues that have led to that lack of regulation, and may point to a way forward for the international co-operation of which she speaks?

[Dr Savage]

I agree with my hon. Friend that the treaty can help to provide clarity about previously unregulated areas. Many countries have already ratified it, which shows that ocean conservation really can unite us where, in the past, there has been disunity.

While I welcome the speed with which the Government have introduced the Bill following the Climate and Nature Bill, thus giving us a seat at the table at the first ever ocean COP next year, it is a little disappointing that the UK was not one of the first 60 nations to ratify the agreement. We hope to be a country that leads on climate diplomacy, so we should not arrive late at the crucial environmental treaty of the decade. While many of our colleagues are in Belém, and with the world preparing for that first ocean COP, the UK must demonstrate not only that it supports global ocean governance in theory, but that it is prepared to deliver it in practice. It is also vital to recognise that the health of our oceans depends on the health of our land-based environment; one cannot heal without the help of the other. We need to decrease our carbon emissions on land if we are to slow ocean acidification, which threatens plankton, ecosystem health, and the millions of people whose lives and livelihoods depend on the ocean.

This responsibility starts at home. That is why the Liberal Democrats have long been pushing for the strongest possible marine environmental targets, both domestically and internationally. If we want credibility internationally, we need coherence domestically. Our own marine protected areas must live up to their name, which means ending destructive practices such as bottom trawling and implementing a clear, science-driven ocean strategy that rises above and goes beyond departmental silos and party-political lines. A strong stance on the high seas will ring hollow if our waters remain vulnerable. The public understand that, the environmental community understand it, and I know that many Members on both sides of the House understand it too. I join my Liberal Democrat colleagues in calling for a coherent oceans policy that joins up our commitment to international waters with stronger protections at home.

As I draw to a close—[Hon. Members: “Hear, hear!”] I am getting there! Let me just say this. If we choose to pursue a strategy of high ambition, the UK can once again be a leader in global ocean protection, championing the first generation of high-seas sanctuaries, pushing for robust monitoring and enforcement, supporting small island states, and ensuring that the benefits of marine science are shared fairly. So yes, the Liberal Democrats welcome the Bill. It enables the UK to participate fully in the new regime for marine scientific resources, for marine protected areas, and for stronger environmental impact assessments. It is necessary, but it is not sufficient. The work that follows will determine its true legacy, and I trust that the Government will continue to draw on the support and perspectives of Members on both sides of the House to secure the wellbeing of the oceans for generations to come.

It is a pleasure to follow the hon. Member for South Cotswolds (Dr Savage). Every time she describes her ocean journeys, I think of that wonderful poem “The Rime of the Ancient Mariner” by Coleridge, which she must have repeated to herself dozens of times while pulling on those oars.

I repeat, very briefly, my welcome for this good Bill, which will hopefully lead to much greater protection for the oceans. However, I want to ask the Minister to respond to one question. Over the years, we have been through all kinds of arguments about Antarctica, from the original Thatcherite concept of mineral extraction to, much later, the protection of the whole continent and the seas around it. On the whaling industry that was, is the Minister satisfied that there are sufficient protections, including for the whales that have survived, and for the growth in their numbers? There are still endless reports of illegal whaling on the continent, particularly by Japan but also by other countries.

The hon. Member for South Cotswolds rightly raised the issue of plastic pollution. There are many wonderful schemes to try to clean up the plastic island in the Pacific ocean and ensure that the plastic is recycled in a proper manner. That is good, and we hope that it will be clean by 2040. The problem, as I understand it, is that two thirds of the plastic is actually under the ocean and not on the surface. Therefore, something else has to be done, but crucially, it is up to us to decide how much plastic flows into the oceans through our rivers, through dumping and through illegal activities. It is the responsibility of our water industry and sewage disposal system to ensure that plastic does not flow into the ocean.
