On that point, will my noble friend give way? I still do not understand the difference of view. The Government refuse to have a carbon intensity target for 2030 in order to give confidence to business to invest in low-carbon generation, but they insist that we have the equivalent for 2049, or whenever it is, because otherwise we will not get investment in gas. At least one of those arguments must be untrue. I cannot understand this utter conflict. They are two different arguments; my noble friend gave the one on the one occasion and now gives the opposite on this. We cannot really accept this argument on the basis of logic.
