My Lords, I, too, express my appreciation of the intentions of the noble Lord, Lord Teverson, and the noble Baroness, Lady Parminter, but I should like to pick holes in the amendment in much the same way as has my colleague, my noble friend Lord Davies. Whereas he considered proposed paragraph (f), I shall concentrate on proposed paragraph (g). It may well be that the amendment is more sophisticated than it seems, because it is possible that the noble Lord, Lord Teverson, is trying to strike a judicious balance between saying something felicitous and saying something that will get past the Minister.
Let me try to deconstruct what is being said in paragraph (g). It is an injunction,
“to progressively increase the energy efficiency of the United Kingdom as measured in terms of quantity of energy used per unit of GDP”.
That is most unlikely to impose a binding constraint. The fact is that the ratio has been decreasing monotonically since 1950, at least, so that in 2010, we used about half the quantity of energy per unit of real GDP as we did in 1950.
I want to make a bigger point than that. I think that we should approach most of what we read in the Bill in a spirit of cynicism and scepticism. I am sorry if that sounds strong, but if we analyse a great many clauses in detail and think of the circumstances in which they would be applied, we realise that they impose non-binding constraints and impose no particular behaviour by the Government that might staunch
emissions, improve efficiency, or whatever. I do not fully understand the motives of the noble Lord, Lord Teverson, and they may, as I said, be more sophisticated than they seem but, if I may be forgiven for saying so, his amendment would perpetrate exactly such an ineffective provision. I hope that he will forgive me.
