Lord Lilley (Con)

I had not intended to speak on these amendments because there are other far more qualified people who I thought would do so. I served on your Lordships’ Environment and Climate Change Committee when it produced the report in July 2023 on the biodiversity agreement in Montreal. As I recall, that commitment, the Montreal treaty, requires Britain to protect 30% of its marine areas by 2030; it was called the 30 by 30 agreement. We were very proud, and I think it was mentioned in that report, that the largest single area of sea that was being protected was the British Indian Ocean Territory’s sea. We accepted tacitly that it was Britain’s responsibility to protect that, that it was a very important area of biodiversity for the world as a whole, and that it was our responsibility. It now seems that we have handed that over to Mauritius, but Mauritius has no means of policing that area. It has no boats or aeroplanes that could cover that distance and that area. I doubt whether we had permanent boats stationed there, but if there were problems we could. We have the capacity to send both sea- and airborne reconnaissance aircraft to make sure that things are being properly respected. I wonder, therefore, whether this treaty which we are now legislating to implement is not in contravention of our commitments under the Montreal biodiversity treaty. Are we abandoning commitments we made there and leaving them, in effect, unpoliced? Another treaty was passed which we did not investigate and which was investigated by another committee of this House. I cannot even remember the name of the treaty but it was about areas of the sea which are outside national jurisdiction. It would seem that this now covers the BIOT—or does it? I hope the Minister will tell us which of these two treaties it is covered by. Is it covered by the old one, which we had responsibility for but have now given up, despite our international obligations under international law, which are normally sacrosanct, or is it under another treaty, which means that it is now dealt with as if it is beyond national jurisdiction? These are clearly very important matters. It is a shame that we are discussing them at this time of night when people far better informed than I, who could bring their expertise and knowledge to bear, are not here. Since they are not here, I am raising these questions and hope that the Minister will be able to respond to them.
