I find that very difficult to follow. This is not a prescription for the means by which we will meet the requirement of a carbon-intensity target. It is an assurance that we are going to stick to that target so that everybody can use whatever mechanisms they have. This is a non-prescriptive concept, of which I approve. It does not say that we have to use this, that or the other. It is a portfolio approach. I still think that the parallel is very clear. If we had been able to stick to our proposition, we would be in a better place today and we would not have to do many of the things that we seek to do today. To ask us to repeat that mistake seems to me a great sadness.
I come back to my first point. The reason we believe that there should be an interim carbon-intensity target is that it is necessary if we are to reach our statutory requirement in 2050. It is necessary for the United Kingdom plc because it gives certainty to people about the parameters within which they will work. If we do not do it, all the noise around what the Government are doing, and the determination to put off to beyond the next election the carbon-intensity target that is now admitted by the Bill, will do a great deal of harm. It will mean that the supply chain that could come to this country will not come and that the jobs and prosperity that should come from our far-sighted decisions will not be gained and earned. We will do very much better to take the advice that will lead to a serious system in Britain that will make us competitive with the rest of the world.
