Climate Change Bill [HL]

I understood the Minister to say that the 2042 budget could not be set to meet the 2050 target. My immediate reaction is, ““Why not?””. It seems incredible that such a situation could arise, but let us suppose that we actually start to make technological change at a rate that permits meeting the 2050 target by 2040 or 2044. What is the problem, if that is the case? It still meets the 2050 target. We could probably go on from there and get even further. So I do not know why the Minister felt compelled to say that the 2044 budget, or whatever, could not actually meet the 2050 target, because patently, if it were technically possible to do so, it should be allowed to do so. If it meets the 2050 target, so what?
