Heathrow (Third Runway)

I am not going to change our position on the national policy statement. The position is as it was in the legislation. We are setting a stretching target for aviation emissions. In the debate a number of hon. Members raised the issue of BAA's broken promises. I know that they feel passionately about that. We need to make clear the important decision that we made. For the first time, air quality will be monitored and enforced by the Environment Agency. Noise will be monitored and enforced by the Civil Aviation Authority. Climate change will be enforced by the Committee on Climate Change. So to those who ask, ““Given the promises made in the past, how can we trust that this will be the case in the future?””, I reply that we are putting in place enforceable mechanisms that will be independently monitored to make sure that that happens in the future.
