Biodiversity Beyond National Jurisdiction Bill

Josh Fenton-Glynn Excerpts

2nd reading
Thursday 16th October 2025 Commons Chamber

[Josh Fenton-Glynn (Calder Valley) (Lab)]

Two thirds of our planet is ocean. Our oceans, which sustain life on Earth, cannot be left unguarded any longer. After years of international negotiation, the world finally agreed to the high seas treaty. With the Bill, we will turn that treaty into action and show that Britain is serious about delivering on its promises.

There is no response to the climate crisis that does not also respond to the nature crisis. That is why it is important to protect biodiversity in this country, beyond our border and beyond the seas. Two thirds of the world’s oceans lie beyond national borders, and until now they have had almost no real protection. The Bill gives us the power to protect international waters by establishing marine protected areas, by demanding proper environmental assessments before deep-sea mining or destructive fishing can go ahead, and by making sure that the benefits of marine science are shared fairly. The Bill underpins the global goal of protecting 30% of the ocean by 2030—a goal that Labour put in its manifesto and one that we should be proud to be delivering on. The high seas absorb carbon, regulate weather and produce half the oxygen that we breathe. If we do not get biodiversity right, we will not get climate change right either.

We have all heard the tedious lines often repeated by Members on the Conservative Benches—where no one is currently sat—that we cannot act because other countries are not acting, but to lead in addressing climate change we have to do precisely that: take action, do something meaningful and lead other countries in making a difference. Hon. Members may wonder why I, from the most landlocked constituency of Calder Valley, am speaking on the Bill, but in Calder Valley we know the cost of climate change as floods devastate our towns. We also know that protecting nature is our first line of defence, and whether that is restoring our moorland at home, insisting on biodiversity net gain in developments or safeguarding oceans abroad, the principle is the same.

I commend the Government for introducing the Bill, which is a vital step in turning the international commitments into real action. The next challenge is to ensure that the Bill not only passes but is properly enforced and resourced, as many colleagues have said. I look forward to hearing more detail on that from the Minister. Let us see this as the first day of Britain’s leadership on our seas.
