Heathrow (Third Runway)

I completely agree. The second promise was to limit capacity, under the so-called green slot principle, to more modern aircraft. That is also welcome, but it is no serious constraint on noise, air pollution or emissions. The most important commitment is the one to limit aviation emissions in 2050 to no more than the level in 2005, when they were 37.5 million tonnes. That artfully conceals the fact that if the Government make the 80 per cent. reduction in climate-changing emissions to which they are committed, that level of emissions will be 30 per cent. of total UK emissions in 2050—and that is not acceptable.
