In light of the Government's decision to approve the expansion of London City Airport, how many more Londoners will live within the new enlarged 57db noise contour, which signifies 'onset of community annoyance'? Please break this down by the boroughs affected.

I do not have population estimates on a borough basis and there are different ways to estimate the numbers of people who will be affected by noise at this level. The methodology agreed by the Secretaries of State for Local Government and Transport when they granted planning permission for the expansion earlier this year predicted that 39,600 people would fall within the 57db noise contour in 2025 should the airport expand, compared to 26,250 people should it not expand. My preferred methodology predicts a further 21,850 people would fall within this noise contour in 2025, bringing the total number of people likely to be exposed to this level of noise to 61,450.

I do however want to ensure that as many Londoners as possible can benefit from noise insulation and I was therefore pleased that conditions to limit noise were put in place. These do not go as far as I would have liked, but I will continue to make the case to City Airport that it should do all it can to minimise its adverse environmental impacts.
