I thank noble Lords again for their contributions to this debate. I will briefly address Amendment 43B. I thank the noble Baroness, Lady Bakewell, for, as I understand it, agreeing not to press her amendment—I hope I have not pre-empted a decision—but more importantly, for her work on this vital issue. I agree with the noble Baroness, Lady Hayman, that she has been very effective at raising this issue on the agenda. I am grateful to her for that, and I hope we will be able to continue to work together on this issue as we develop a robust pesticide action plan. I thank her very much indeed.
Much has already been said regarding storm overflows, so I will keep it brief. I thank Members across the House and in the other place for their informed, valuable and passionate contributions. I am pleased that we were able to announce progress today. In response to the noble Baroness on the Front Bench I say that, while the Government must vote against this amendment today, for procedural reasons and to ensure that the House of Commons has an opportunity to deliver the proposed amendment in lieu, that is not a reflection of an ideological difference; it is simply a procedural issue.
My noble friend Lady McIntosh asked a number of questions, in particular about a timeline for the implementation of Schedule 3. It has already commenced and will be completed in 2022; I cannot give a month, I am afraid.
I very much appreciate the comments of the noble Baroness, Lady Jones of Moulsecoomb. On the costs that she talked about, there is a difference between the cost of eliminating harm from overflows and the cost of eliminating overflows. It is the cost of eliminating overflows to which those figures apply. I will not pretend that I have been through the figures myself but, based on everything that I know, the range is anywhere between £150 billion and £500 billion. In real terms, it is not a relevant figure, in that no one is proposing that this amount of money should be spent on infrastructure. The key is the elimination of harm, which would allow the overflow to happen in some cases and for investment in sustainable systems such as reed beds and the like. That would not be the elimination of overflows but it would be effective management of them. It is, however, the correct figure for eliminating overflows.
The noble Lord, Lord Adonis, asked a question on the chemical issue. Again, it is not the case that there is a shortage of chemicals preventing the water companies doing their job. There is currently no disruption to the supply of water, water treatment or the treatment of wastewater. The shortage of HGV drivers had meant that there was a risk that deliveries of ferric sulphate, a water treatment chemical, would be delayed, but the Environment Agency successfully and very quickly mitigated that risk.
On Amendment 65, tabled by the noble Lord, Lord Krebs, I assure noble Lords that the Government will publish a nature recovery Green Paper in the coming months, setting out our approach to supporting nature recovery in England. It will show our commitment to and focus on this matter, which I know is enormously important to almost everyone in this House.
On Amendments 94 and 95, in the name of the noble Baroness, Lady Meacher, I reiterate that we will not have in one year meaningful data with which to assess the effectiveness of this legislation. However, the disagreement that we have is entirely practical; it is not based on our hopes for the effectiveness of this legislation. As I said before, if it is clear before two years that something bad has happened and the Government have chosen to exploit or create a loophole, we will act long before the review deadline of two years. It will be very obvious to us should that be necessary.
Moving on to Motion K, although I ask the House to disagree to Amendment 66, in the name of the noble Baroness, Lady Young, I very much appreciate her remarks and her commitment to the issue; she has pushed it right up the political agenda in a very effective way. I hope that your Lordships’ House will welcome the Government’s progress and the commitment to enhancing the protection of ancient woodlands, on which the noble Baroness and I have agreed, I am delighted to say.
On Motion M, I hope that noble Lords can support the Commons in its Amendments 67A to 67E, which will provide further reassurance to landowners on the issue of conservation governance.
I hope noble Lords agree that, in addition to the progress made in Committee and on Report, we have moved further today to protect our waters, our trees and our landscapes for future generations.
