Climate Change Bill [Lords]

I was, of course, paraphrasing what Lord Turner had said. It was not my personal view that emissions from aviation might continue to grow and could not be reduced by 80 per cent. by 2050. We can be optimistic, can we not? My hon. Friend makes a good point—there is new technology and we are very supportive of that. We know that new aircraft are producing lower emissions than existing ones. Much can be done in that field, although I am sure that much more will eventually have to be done, too.
