Biodiversity Beyond National Jurisdiction Bill

Debate between Baroness Miller of Chilthorne Domer and Baroness Jones of Moulsecoomb

Committee stage
Tuesday 16th December 2025 Grand Committee

[Baroness Miller of Chilthorne Domer (LD)]

My Lords, this amendment and Amendment 10 are concerned with plastics pollution. Amendment 6 would require the Secretary of State to assess and respond to the risks to marine biodiversity of plastics pollution that arise from activities that are either under UK control or within UK jurisdiction. This is especially important given that the global treaty on plastics is stuck in dispute.

Plastics pollution in the oceans is subject to ocean currents and the polluter, the originator of that plastic, is often in a very different part of the world from the polluted seas and beaches that result from it. The first time this struck me with such force was when I was in Mexico in the biosphere known as Sian Ka’an, in Yucatan. There were incredibly unspoiled, amazing beaches and very little population. I could not understand why the beaches were covered in plastic, especially plastic shoes. They were sweeping up from South America on the currents.

As the BBNJ comes into effect, besides an effort to lessen what goes into the ocean, it will need, and has provision to include, remediation and removal activities. The agreement sets out the process for the submission of proposals by states and the review of the same. Does the UK yet have proposals that it intends to submit? What is the UK doing on ocean plastics and what does it need to do?

The UK is very active in the International Maritime Organization talks working towards future mandatory rules to reduce risk from nurdles—plastic pellets that are transported by sea in freight containers. The Government have also supported the global plastics pollution treaty, which I referred to earlier, are seeking commitments to reduce all sorts of plastics entering the oceans and have developed standards through the BSI.

All of that is very positive, but they have not yet introduced binding national legislation to prevent nurdle loss. This is very topical, because of that huge loss that ended up on Camber Sands from a sewage plant. The UK has no binding laws that specifically regulate the transport, storage, reporting or mandatory spill prevention of plastic pellets in the way that the EU’s new plastic pellet regulation does. I know that UK Ministers have said that there are no current plans to align UK regulations with the EU’s stricter pellet transport regulations and storage requirements, but will the Government rethink this in the light of joining this treaty? That is another example of where we could take much better action now that we are part of a treaty that concerns the oceans.

Ultimately, we have to switch from using so much fossil fuel-based plastics to using biodegradable plant-based products, and renewable energy in place of fossil fuels, so that our oceans stop warming and acidifying. The two things are incredibly linked. It is a multi- generational challenge, but this treaty is a terrific step on the road. I beg to move.

[Baroness Jones of Moulsecoomb (GP)]

I very much support Amendment 6. In fact, most of the amendments in this group are sensible. Forgive my ignorance, but surely if we pass the criteria for the international treaty, what is to stop us adding things to the Bill? Is there anything? We could, could we not? It would be irrelevant for the international treaty, but relevant for our Government. Quite honestly—I am looking around the table at all these plastic bottles—our plastic use is horrendous. That is what this amendment is about. It is within the scope of the Bill and speaks directly to the aim of what we are trying to do.

The agreement’s preamble is clear. It recognises the need to address biodiversity loss in the ocean caused not just by climate change but by pollution, specifically plastic pollution. In other words, plastic is not just a side issue here; it is identified as one of the core pressures driving the destruction of marine biodiversity in areas beyond national jurisdiction.

Plastic pollution is now found throughout the ocean, from the surface to the seabed, in some of the most remote parts of the seas. It causes injury and death, enters the food chain as microplastics and adds further stress to ecosystems already under strain. One floating patch of plastic out on the remote sea is three times the size of France. It is not the only giant patch. We are producing roughly the same weight of plastic each year as the weight of humans on the planet, and that is projected to keep going up. I do not know who put these plastic bottles here, but can we please complain about that? What is wrong with refilling glass bottles? I do not understand why we would add to the problem.

Amendment 6 is about making sure that, when we have a chance to make a difference and improve our sea, we can do so. The Government need to set out how they will assess and respond to the risks that plastic pollution poses and how the UK will work with international partners to reduce and monitor that harm. The amendment would help ensure that the UK takes every opportunity to lead rather than leave a recognised threat unaddressed.

Having suggested that the UK could lead on this, I feel it is rather undermined by the fact that most of our own marine protected areas are barely protected at all. There is bottom trawling, dredging and overfishing. We need to sort that out for ourselves. Signing up to international treaties is brilliant—it is good to work with other countries—but not if we cannot even manage our own resources. The five-year review is fantastic, but what about a five-year review of our own marine protected areas? The human use of plastic and fossil fuels is driving our destruction. I do not understand why the whole House cannot see that—in fact, the whole population.
