My Lords, I think those on the Conservative Benches should support the noble Lord, Lord Oxburgh, as well—as indeed I am sure many of us do. I agree very much with the noble Lord, Lord Cameron, who says that we simply have to value our natural resources. We in this country are totally out of step with the whole movement towards valuing natural capital and understanding the extent to which our natural resources underpin our economy and our quality of life. It makes obvious sense, therefore, that we should all be aware of our footprint, and if we think that we have the right to buy water at a rate that reflects some old rateable value as opposed to our actual consumption, we are simply denying our responsibility to understand our long-term impact.
As I understand it, this amendment is tabled more in order to demonstrate that the water companies can already do what the amendment seeks that they do, so I expect that the Minister will say that it is unnecessary, but it is certainly not unnecessary if it demonstrates what is obvious. I cannot understand why anyone should say that it is against the tide of the day; it is my understanding that every party supports the idea that we should value our natural resources properly, and who could say, therefore, that water should be exempt from that process?
