Biodiversity Beyond National Jurisdiction Bill

Amanda Martin Excerpts

Monday 17th November 2025 Commons Chamber

In conclusion, our amendments share the aim of strengthening this Bill by ensuring proportionate oversight and clear accountability to Parliament and the British public. They would ensure that Parliament remains properly informed; that ministerial powers are exercised transparently; and that our world-leading scientists and industries can comply with the new regime without unnecessary bureaucratic burden. Far from hindering the Bill, our amendments would bolster its credibility and effectiveness, supporting our international obligations and, crucially, our British national interests. On that basis, I commend them to the House.

It is a privilege to serve under your chairmanship, Ms Ghani. I want to speak on this Biodiversity Beyond National Jurisdiction Bill both as the Member for a coastal community, and as someone who is truly fortunate to have dedicated environmental campaigners locally. I want to thank one constituent in particular, Viola. Her emails cover everything from ocean acidification to regenerative farming and the health of our chalk streams. Although I cannot always provide the answers that she needs, I thank her for her valued, informed and tireless campaigning.

Much of what Viola raises is exactly why this Bill matters. It matters for the important issues of pollution, harmful algae blooms in Langstone harbour, and the need to protect local bird species and our drinking water. We must be proactive on ocean heating, bottom trawling and the worrying tipping points we face in ocean acidification, as well as on regenerative farming, reducing pesticides, and protecting soil health, so that rivers, seas and pollinators can recover. Although this Bill focuses on biodiversity beyond the national jurisdiction, the principle is the same. What happens in our oceans—from the south coast to the high seas—affects us all. That is why the Government have tabled amendments to strengthen the Bill and provide clarity and accountability.

I particularly note Government amendment 1, which updates section 81 of the Marine and Coastal Access Act 2009 so that it accurately reflects the extended conservation responsibilities created by this legislation. This may seem technical, but accuracy matters, especially when we are embedding in law stronger protections for vulnerable marine ecosystems, including those far beyond our waters. Through this Bill, we will ensure that the UK plays a serious, leading role in implementing the high seas treaty, tackling the over-exploitation of shared oceans, and improving transparency and reporting. Government amendment 2, which tightens the environmental impact assessment provisions, will help to ensure that the framework that we set up is robust, enforceable, and capable of delivering real biodiversity gains beyond our borders.

While stakeholders may not always agree on how best to align planning reforms with environmental goals, we have a shared mission to restore nature, not merely preserve what is left. This Bill is one part of that mission. By strengthening the UK’s hand in protecting biodiversity on the high seas, the Bill reinforces the protection we all want to see everywhere from Langstone harbour to Antarctica. It demonstrates leadership and this Government’s commitment to restoring nature on every scale.
