Biodiversity Beyond National Jurisdiction Bill

Roz Savage Excerpts

2nd reading
Thursday 16th October 2025 Commons Chamber

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

The oceans have long struggled to get the attention they deserve—there are no voters out there on the ocean. Thanks are owed to Sir David Attenborough and the many filmmakers and photographers who, over the years, have brought the oceans into our living rooms and helped us to get to know them and care about them. Most of us only get to experience oceans from a beach, or from 30,000 feet—looking down from an aeroplane window at a vast, endless blue expanse—but I have spent months and months alone on the ocean, a long way beyond national jurisdictions, rowing across oceans to raise awareness of the environmental crisis facing our world, particularly the parts of it that are blue. I was trying to bring a human face to the plight of our oceans.

Out there in the middle of an ocean, when you have not seen dry land for several months, thousands of miles separate you from the closest land mass and the nearest human beings are on the International Space Station, it feels like you are well beyond jurisdictions, and often beyond justice. It was out there in that lawless place that I came to understand both the power and the fragility of the ocean—you see its beauty and its bounty, but also its vulnerability to what we humans choose to do. The ocean has no voice in this place, so today, we are being its voice.

The ocean may seem boundless, but it is not indestructible. We have polluted it, overfished it, and warmed it. The deep sea is home to some of the most extraordinary forms of life on Earth—I was particularly pleased to hear the Minister refer to sunfish, which are surely the weirdest creatures I have ever seen—but it is increasingly targeted for exploitation. We know the surface of the moon better than we know the bottom of the ocean. There is a real danger that we could destroy species before we even know they exist.

More than 60% of the world’s surface and nearly three quarters of its ocean volume lie out there in the places beyond any country’s control. For centuries, the high seas have been treated as no one’s responsibility—beyond the environment, a lawless expanse—and still today, only 1% is properly protected. Meanwhile, overfishing, pollution and deep-sea mining are degrading ecosystems that we barely understand. The ocean is becoming more acidic, threatening the existence of plankton—the base of the entire marine food chain—and weakening its capacity to absorb carbon and regulate our climate. That is what is at stake. The health of the ocean is the health of our planet.

That is why the biodiversity beyond national jurisdiction treaty matters so profoundly. It is the first global treaty to bring order, fairness and protection to the high seas. It offers a framework for managing those shared waters responsibly and ensuring that the benefits of ocean science are shared globally, not hoarded by the few. Earlier this year, when I brought the Climate and Nature Bill before this House, I further pressed the Government to commit to ratifying the BBNJ, and I am pleased and thankful that they are now delivering on that promise. I particularly thank the Minister, the hon. Member for Kingston upon Hull West and Haltemprice (Emma Hardy), for her long-term persistence and commitment to this cause. It shows that when we work together across the House, we can turn ambition into action.

However, ratification is only the beginning; turning this treaty into a practical reality will demand co-ordination, funding and focus. As such, I would like to ask the Minister a few practical questions about implementation from the FCDO perspective, questions that I have sent to her office. First, on institutional co-ordination, how will Departments such as the FCDO, DEFRA and the Department for Transport work together to manage marine genetic resources, environmental assessments and new conservation tools under a single, coherent system? Secondly, on enforcement, what mechanisms will ensure compliance by UK vessels and research institutions operating beyond national jurisdiction, given the real challenges—of which I am keenly aware—of surveillance and jurisdiction at sea?

Thirdly, turning to resourcing and capacity, have the Government assessed the staffing, budget and technical resources needed to set up the new repositories, databases and administrative systems required by the BBNJ? Fourthly, on transparency and fairness, what plans are in place to ensure that the data held by repositories such as the Natural History Museum and the National Oceanography Centre are accessible and interoperable—especially for developing countries, including small island states—in line with the BBNJ’s principle of equitable benefit sharing? Finally, on international engagement, with the first oceans COP expected in 2026, how will the UK prepare to shape the operational details of the agreement at the international level, and who will represent us at that table?

These questions matter because they will determine whether the Bill delivers real protection, rather than just good intentions. Our scientists are ready to lead. The National Oceanography Centre, with its cutting-edge research and fleet of autonomous submersible vessels—including one known as Boaty McBoatface—is already mapping deep sea currents and gathering the knowledge we need to understand and protect the ocean. Under the BBNJ, that vital work will become part of a global effort to heal the seas.

The ocean is the blue heart of our planet. It gives us half the oxygen we breathe, shapes our weather, and sustains life on a scale that defies our humble human imaginations. If that heart falters, everything we depend on will be at risk. We often think of oceans as dividing nations, but actually, they connect and unite us; we are, so to speak, all in the same boat. As the great American oceanographer Dr Sylvia Earle said,

“We need to respect the oceans and take care of them as if our lives depended on it. Because they do.”

By ratifying and implementing the BBNJ, we can help turn the tide—sorry, I just cannot help it. Let this be the Parliament that gave the ocean a voice and a future.

Biodiversity Beyond National Jurisdiction Bill

Roz Savage Excerpts

Committee of the whole House
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.

[Jeremy Corbyn]

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.
