Contribution
I thank the Minister for her response, which has finished bang on the dot of 20 minutes. I take this opportunity to thank all colleagues who have participated in the debate. The contributions have been fantastic and reaffirm yet again the breadth and depth of knowledge that runs deep through Members of this House.
The time is late so I will not keep the Committee long, but I have a couple of points—I have made lots of notes, but I shall mention just a couple before we close this debate. I thank the noble Viscount, Lord Hanworth, for his contribution and for reminding us that there was a time when inert dinitrogen gas, N2, was in equilibrium with bioavailable, more reactive nitrogen in the soil, so things do not have to be like this. Modern society and our burning of fossil fuels have contributed to reactive nitrogen, but the energy-intensive Haber-Bosch process has led to the mass production of cheap fertilisers that are being overused—and abused, really.
I am not going to run through everything, but I will try to pick up a couple of points made by the noble Lord, Lord Fuller. All I will say is that a 1% per annum reduction in artificial fertiliser inputs, which is the aim of the company that he represents, pales in comparison with the experience of the noble Earl, Lord Leicester, with regenerative farming. The noble Earl achieved a 20% reduction in two years, while a rate of 1% will take 20 years—I just wanted to point that out. At the same time, I congratulate the noble Earl on his fantastic work in this field. It will make a real difference to have someone of his stature and capacity leading regenerative farming. If he were to throw his weight behind this, that would be a game-changer, so I welcome his input.
I think the noble Lord, Lord Fuller, mentioned a 39% reduction in fertiliser input since 1989. Quite a lot of that came at the same time as the reduction in livestock numbers. We know that food grown to feed cattle and other livestock takes up a lot of our inputs, which may well explain the large numbers since 1989.
I think it was the noble Lord, Lord Ashcombe, who mentioned roads. We deliberately chose not to look at nitrogen emissions from roads because they have fallen quite a lot, by 70%. The committee recently did a report on the uptake of EVs—we can see in today’s media that we had a record year for electric vehicles last year—so we felt we should concentrate on agriculture and wastewater, where reductions in nitrogen emissions have been much more stubborn. I pay tribute to the noble Baroness, Lady Whitaker, for her work in making sure that we do not lose sight of indoor nitrogen pollution from cookers and domestic boilers. She will do us all a service if she stays with that issue and makes sure that we do not lose sight of it.
I will wrap up. The Minister commands respect around the House, certainly from me, so I really welcome her words. However, I received an email recently about a meeting in October of the United Nations Economic Commission for Europe. The email says that, at that meeting, the UK succeeded in having struck from the meeting record that there are any cost-effective low-hanging fruit for ammonia mitigation. That was a pity, since reaching agreement on that point was the centrepiece of the evidence that the Task Force on Reactive Nitrogen provided to the meeting. I am sure that these discussions will continue, but that fills me with trepidation. I look forward to the Minister writing to me to verify that email or otherwise. I have to say, it comes from an extremely reputable source—otherwise I would not have brought it up. I apologise to the Minister for bringing it up, but it is crucial to this debate.
Our report was undertaken in response to the widely perceived failure of successive Governments to effectively manage nitrogen pollution. I am sorry to say that the Government’s response to date and the information I have just relayed do not inspire confidence that their response matches the scale of the problem or the opportunities available. However, I look forward to further discussions. I beg to move.
