Heathrow (Third Runway)

I do not think I need detain the House in racking my brains for an instance when BAA may have kept a promise. The whole House knows the thrust of the right hon. Gentleman's argument and my argument, and I concur entirely with what he is saying. So we have a solemn commitment to do something about air quality, which was pretty bad in 2003 and is a lot worse now. Air quality is the big one—certainly for me, representing a Thames valley constituency. The Thames valley suffers from very high levels of asthma among its children and young people, which is an issue that I will return to. We know that, in common with nine other European Union countries, we are about to be in breach of the European air quality directive. That is why the Government are about to apply for a derogation, which can last for only five years. I have to tell the House that there is no guarantee that that derogation will be successful. I have been passed a letter from the Environment Commissioner, Stavros Dimas, which makes the situation clear. Article 4 of the directive"““sets a limit value of 40 micrograms/m3 for NO2 and requires this limit to be achieved by 1 January 2010.””" The letter says that it is possible to derogate, but"““States wishing to do so must notify the Commission and bear the burden of proof to demonstrate that the conditions for the postponement are met. If the Commission decides that the conditions for a postponement or an exemption have not been met, it may raise objections within nine months of receipt of the notification.””"
