Commons ChamberI thought the right hon. Gentleman was going to provide some clarity from the Dispatch Box about the breach of the CO2 limits that I have just described, but instead he asks that question. In fact, we know that we are talking about considerably more than that. It is utterly absurd for the Government to ask the House to vote on expanding Heathrow without a plan for reducing aviation carbon emissions. Under the revised NPS, there is a very real risk that aviation’s carbon emissions will be higher in 2050. Furthermore, the Department for Transport is not due to publish a new aviation strategy until 2019.
My hon. Friend is right that the environmental case against Heathrow expansion has always been unarguable; what has changed is that the economic case is also now very strongly against it. The net present value is plus or minus £2 billion to £3 billion over time. The case for Gatwick, which would be much easier to build and would involve far less grief, is much easier than that, so whether on economic or environmental grounds, Heathrow is a non-starter.
I am grateful to my hon. Friend for that intervention. He makes a powerful point, which many commentators have identified, about the various economic arguments.
