Biodiversity Beyond National Jurisdiction Bill

Debate between Roz Savage and Nusrat Ghani

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.
