If NOx exceedances are already well above permitted European Union levels, how can they conceivably be brought below those mandatory ceilings if there is a 50 per cent. or even a 25 per cent. increase in flight movements? Have the Government sought from BAA precise details of the mechanisms that are intended to bring them below those ceilings, and by how much each mechanism is expected to do so if there are 600 additional flight movements per day? If the Government have that evidence, will they publish it now, in full? If they do not have the evidence, is it not irresponsible for them to rely on BAA assurances without evidence to support them, especially given that the present level of exceedances will lead to EU fines of perhaps hundreds of thousands of pounds per day after January 2015?
