Biodiversity Beyond National Jurisdiction Bill

Martin Rhodes Excerpts

2nd reading
Thursday 16th October 2025 Commons Chamber

[Martin Rhodes (Glasgow North) (Lab)]

I welcome the Bill for what it seeks to put into law, but also for what it signals about the approach of the Government, and hopefully this House, to national and international obligations and interests. It is a testament to the continued survival and delivery of multilateralism in global affairs. In an age of continued and heightened global strife, conflict and antagonism, the Bill is proof that there still remains hope for global co-operation and that joint endeavours with shared purpose can deliver common goods. Institutions such as the United Nations can still be practical and effective forums to facilitate states coming together to work out collective solutions to collective problems. There are those who seek to withdraw from international agreements, seeing multilateral institutions and processes as threats. We must eschew such an approach, because it ultimately does not serve our national or global interests. Such an approach of withdrawal and isolation will not further our interests effectively.

In this case, the United Nations biodiversity beyond national jurisdiction agreement, which the Bill will bring into the framework of UK law, will be one of the most important strides forward for biodiversity and the marine environment. For the first time, the United Kingdom will have a legal framework to help us to protect large expanses of the seas that are beyond our national waters. The establishment of such protections will help to ensure that regions of the high seas are safeguarded from harmful extractive and destructive practices. The protections will help to restore biodiversity to these regions and help maintain the ocean’s capacity to absorb CO2 produced by human activity, thus helping to mitigate the impacts of global warming.

As has been mentioned, the oceans absorb about 30% of man-made CO2, and this treaty will help to ensure that they are fit to continue doing so. The ratification of the treaty must not be the be all and end all for protecting the biodiversity of the world’s oceans. It must be a means through which the UK and allies globally can continue to advocate for greater protection of our shared marine environment. One means of doing that through the treaty will be the first conference of the parties—or Ocean COP1. This will be the first forum for the treaty’s signatories to discuss and action its implementation, such as agreeing proposals for the first generation of high seas sanctuaries. The treaty is welcome and the Bill is welcome, but implementation is necessary to deliver what we need.

As the Minister said in her opening comments, the COP will take place within a year of 17 January 2026, which is when the treaty comes into force. As has been said, if the UK has failed to ratify at least 40 days before that date, we will not have a seat at the first COP. That is why I urge the House to pass this legislation at pace. Already, there are reports that the first Ocean COP could be as soon as August next year. The Government have rightly spoken at length about the importance of the UK bringing its soft power to bear. With this being the first COP of its kind, it is essential that we bring UK expertise and influence to the event while the treaty is in its infancy. We have seen the importance of conferences of the parties as a means of promoting collective action on climate change and nature. We cannot miss this chance to be a part of the first Ocean COP to do the same for our world’s oceans. Multilateral agreements implemented by collective action are the way forward on this issue. I am therefore more than content to support the Bill enthusiastically today.
