Heathrow

If I could make a little more progress, I will give way in due course. We recognised at the time that this would have implications for people around Heathrow, which is why we have made that commitment subject to meeting stringent local environmental conditions. Let me remind the House of what those conditions are. First, we must meet our European obligations with regard to local air quality. That means that pollution from particulates and nitrogen dioxide are within prescribed limits by the time any capacity changes are implemented.
