Biodiversity Beyond National Jurisdiction Bill

Tristan Osborne Excerpts

2nd reading
Thursday 16th October 2025 Commons Chamber

[Andrew Rosindell]

The chairman of the Foreign Affairs Committee is, I am afraid, incorrect. We have raised those issues on many occasions, and I have personally raised them on countless occasions over the years. Before too long, the right hon. Member will hear a bit more about the Chagos Islands and the importance of protecting marine stocks and biodiversity in that part of the world.

Despite what has been said today, I fear that at this stage the Government are riding roughshod over that record and undermining those very principles through their abject surrender of a marine protected area. The British Indian Ocean Territory might look like a scattering of remote atolls in a far-flung region of the planet, but they are home to 640,000 sq km of ocean—one of the most pristine marine ecosystems on the earth, an area of ocean the size of France. Within it live more than 1,000 species of fish and over 200 species of coral.

I had the opportunity to see it for myself in 2019 when I visited the Chagos islands, in particular the atoll of Peros Banhos, where I was greeted by the wonderful Chagossian coconut crabs, as I jumped out of the dinghy and walked on to the beach and into the uninhabited island—where we shamefully forced the people to leave their homes all those years ago and refused to allow them to return. Its waters shelter seabirds, turtles and dolphins. It is an environmental treasure that the world envies and that Britain has rightly protected over so many years.

Is the hon. Gentleman aware that Mauritius was one of the early signatories to the UN global ocean treaty? If so, I am not sure what his point is.

[Andrew Rosindell]

The hon. Member should examine how Mauritius behaves in reality, which I will come to later. If we want a nation that will actually take these issues seriously, it is the United Kingdom. It is easy to sign a treaty, it is not so easy to follow it through in practice.

In what I believe to be an act of historic folly, this Government are to hand that amazing territory over to Mauritius. That nation does not have the record, the capability or the will to protect such a fragile environment. Its own waters have suffered from overfishing and poor enforcement. Its close alignment with China, and indeed India, should concern anyone who cares about the Indian ocean’s future. Indeed, the evidence speaks for itself. In the 2024 Environmental Performance Index, Mauritius ranked 109th for marine key biodiversity area protection, with a score of just 0.8 out of 100; 83rd for marine habitat protection; and 131st for marine protection stringency, down nearly 78%. Are these the credentials of a nation ready to steward one of the world’s most delicate ecosystems? The Government appear to think so. I disagree.

“It seems to me that the natural world is the greatest source of excitement, the greatest source of visual beauty, the greatest source of intellectual interest. It is the greatest source of so much in life that makes life worth living”—wise words by David Attenborough. They are words that everyone can relate to, whether that is a university professor in Oxford, a 12-year-old watching “Blue Planet” on the BBC or, indeed, the specialist in ocean conservation I met yesterday as part of my role as vice-chair of the all-party parliamentary group for the ocean. Everyone in this room, in this country and on this planet has an interest in ensuring that our oceans are protected.

When we stare down from space at our blue jewel of a world, it is simply unfathomable that 230 million square kilometres of it are at present effectively unmanaged. It is a free-for-all. It has been allowed to become so because of history, but we now have the obligation to create a system of management, both in this room and across multilateral agreements with other countries. It is the wonder of our democracy in this country and other countries around the world that we can finally introduce a piece of legislation where we can manage many of these locations.

I stand as a proud MP for Medway, in particular Chatham, which has an historic dockyard that served much of our maritime trade and provided support to the Royal Navy. Many in my community have a proud history and legacy of serving on the oceans, from working on fleets supplying freight to participating in our royal naval tradition.

Our country has a proud history of conservation through the National Trust and other terrestrial organisations. We also have a number of third-party sector organisations that are committed to delivering on ocean conservation, not just through this treaty but through the many there have been in the past. Such organisations include Oceana and the Marine Conservation Society.

There is also excellent work being done by Plymouth University and Southampton’s National Oceanography Centre, which my hon. Friend the Member for Brent West (Barry Gardiner) and I had the pleasure of visiting earlier this year. Our Natural History Museum, with its work in London and across the country, the World Wildlife Fund and Greenpeace have all advocated for this in many ways and continue to do so. In many cases their work is not high profile; they do their work quietly and behind the scenes, such as by engaging with DEFRA—I am sure the civil servants can attest to this—and ensuring that they are safeguarding our fisheries and world.

This Bill is extremely welcome and timely. The high seas treaty reached its required 60 ratifications on 19 September, and the 60th ratification triggered a 120-day countdown, after which the treaty comes into force. If we want to be at that multilateral table to deliver for our residents in our communities and our country, we need to deliver this legislation. I welcome the Bill being placed before the House, and I welcome the debate with Members across this Chamber—from those who are fascinated by the sperm whale or the right whale to those who have rowed across oceans and seas.

The contents of the Bill are critical. Genetic heritage has not been mentioned much today, but it is a critical element as it can lead to cures for cancer and heart disease. Genetic heritage is a marker for our future on this planet. If there are cures that come as a result of this legislation, it is today that we give security and licence to it. The designation of marine protection areas has been much debated across this Chamber with regard to UK controls, and I agree with many of my colleagues that we need to do more domestically to protect our MPAs, make them fit for purpose and allow them live up to their designation.

This legislation creates the licence for marine protection areas in international waters, which will support our heritage and legacy for future generations. It is a pathway to the goal of protecting 30% of the world’s oceans by 2030. The Bill also gives scientific protections around licensing. We know that there are significant challenges for both our biotic and abiotic resources. Much time has been spent this afternoon discussing the damage caused by international industrial fisheries, with new technologies and industrial-sized trawlers coming from many nations of the world. The damage caused by these monsters, as I refer to them, is decimating not only our biological resources directly in that location but sea birds, species and any food chains associated with it.

There is also a debate about mining and drilling to be had in the next 10 to 20 years as we begin to get access to our deep-sea resources. Whether it is hydrates or base metals that we need, we need to have that conversation, so I implore the Government to look very closely at any moratorium. Then there is climate change, which is not to be denied by many across the world. It is happening. Species are under threat, and the destruction of habitats as a result of the warming and acidification of the ocean is impacting both coral reefs and seaweed beds.

To conclude, I still have a number of questions around the use of the Marine Management Organisation in this country and regional fisheries management organisations. How much extra resource will they need, because I certainly have questions at present around the MMO and its oversight? How do we know that this is going to be enforced? The UN has calculated that to make this effective we might need to look at figures of around $170 billion annually. Where is that money going to come from?

There are serious questions about who will enforce overfishing protection and marine protection areas when we have fishing piracy going on around the world. What are the measures for dispute resolution? We know that there are United Nations convention on the law of the sea disputes around the South China sea with China, and disputes are also ongoing over the Arctic, so what measures and mediation will this treaty introduce? This treaty tells everyone watching about our values, whether they be a 12-year-old “Blue Planet” watcher or a professor in a submersible in the Arctic. It sets the tone for the next hundred years. It is necessary that we do this and I implore colleagues to support it.

That brings us to the Front-Bench contributions. I call the Liberal Democrat spokesperson.
