Deep Sea Mining in International Waters

Lord Purvis of Tweed Excerpts

Monday 30th June 2025 Lords Chamber

[Lord Collins of Highbury (Lab)]

It has been made public that legislation will be introduced by the end of the year to enable the ratification of the BBNJ agreement. That agreement includes processes to ensure better co-ordination and co-operation between international bodies responsible for ocean governance, including the ISA.

[Lord Purvis of Tweed (LD)]

Will the Government confirm, as the ISA has, that their view is that the executive order is contrary to international law, when it comes to the law of the seas, and contrary to the requirements under UNCLOS? Did the Government note the statement by the head of the ISA, in response to the executive order, in which she reminded all parties of UNCLOS, which includes the United Kingdom, that they

“have a duty not to recognize any acquisition or exercise of rights over minerals recovered from the Area”?

Can the Minister reassure the House that in our trade talks with America, we have made perfectly clear that we will honour the international law of the sea, honour our commitments under UNCLOS and not trade with any US enterprises that disregard them?

[Lord Collins of Highbury (Lab)]

I think I need to respond in a positive way. I can be absolutely clear what we are in favour of. The major priority for the ISA is to agree a regulatory regime for exploitation, and we have been engaged in these negotiations from the start. The ISA has agreed a road map for continued work on the regulations with a view to their adoption in 2025. We will actively participate in those negotiations at the council of the ISA next week. We are absolutely committed; we know what we have to do. We know that the ISA council has agreed that deep sea mining should not take place in the absence of these regulations. That is what we will be committed to, and that is what we will say to all our allies.
