My Lords, I support the noble Baroness, Lady Willis, in her Amendment 390, to which I have added my name. It is a really important amendment as we struggle to meet the Government’s environmental target and our need to build more homes and develop our land. We have to do that in a way that understands there are fundamental environmental problems we need to address, particularly nutrient pollution.
It is clear that we need a statutory underpinning for nature-based solutions because, without that, they are not going to happen. We have evidence of that. You only have to look through previous price reviews, in which Ofwat turned down recommendations from water companies for nature-based solutions because, on a crude cost-benefit analysis, putting in a grey concrete storm tank was a damn sight cheaper than wetlands and various other proposals. If my memory serves me right, Ofwat turned down some very detailed and thoughtful proposals from Anglian Water because of the cost. Unless there is statutory underpinning, Ofwat will just carry on with its usual economic model.
This amendment is an important way of ensuring we get that win-win of nature-based solutions as we seek to address our nutrient pollution problems. It is an elegant way to move forward on the Dasgupta review, which talked about finding new ways to build nature into our economic model. Giving this a statutory underpinning would, as I have just made clear, give Ofwat the confidence to build into its economic models support for nature-based solutions. We know these are going to be fundamental if we are going to get to our 30 by 30 target.
The only thing I want to say, because it is late and so much has been brilliantly said by the noble Baroness, Lady Willis, is that you would expect us to say this. We are the usual green environmentalists. But I hope the Minister hears that we are also saying that we understand why this is important. We need development, and there is stalemate in many housing developments because the nutrient pollution issues cannot be solved. We are trying to be constructive in resolving that problem. We are not just saying this with our usual green hats on. We realise that this is a tricky issue which needs resolving.
It is not just us in the environmental groups, such as Wildlife and Countryside Link. The House of Lords Science and Technology Committee did an excellent report on nature-based solutions recently. Again, this underpins the support for this amendment. The Government’s own environmental improvement plan talks about the benefits of nature-based solutions. If you are going to deliver on your own words, then you should be supporting this.
For me, the most important and powerful thing is that the water companies support this amendment. In addition to the comments made individually to the noble Baroness, Lady Willis, Water UK put out a release saying that the water companies want this amendment. It would be wonderful to be able to say that this amendment has been supported on a day when the
water companies have said, “Mea culpa”, said sorry for the appalling way that they have handled our sewage problems, and promised that they will put £10 billion-worth of new investment into this area. This would ensure that we get the win-win, both to overcome some of our problems with building the homes we need and to ensure that we get the benefits we need for our hard-pressed nature.
