The fourth carbon budget review is under way. I will not prejudge that, and the hon. Lady should not expect me to do so. I will say that this Government are leading the international climate change debate in Europe. The 2030 energy and climate change targets, which will be discussed at the European Council in

March, are critical in tackling climate change. She will know that we have to work internationally to do that. This Government and the UK have been leading that debate.
