I should start by saying that this Government are absolutely committed to being the greenest Government ever. In fact, one of the first decisions that we implemented was to cancel the third runway at Heathrow. As a London MP, I was delighted, because much of my time as first-term MP in opposition had been spent campaigning against it. I recall vividly a conversation with the now Leader of the Opposition when he was Secretary of State for Energy and Climate Change, and waved through the plan to increase the number of runways at Heathrow. That would have had a hugely detrimental effect on carbon emissions. I have no doubt that he recalls our conversation, when I begged him to see sense. He did not, but fortunately the electorate did, and we now have a Government who realise that a third runway would have been a green disaster.
