Expansion of Heathrow, a third runway?
Think again, the existing infrastructure cannot cope.
Late Friday afternoon, on the M25 on the approach to Heathrow, nose to tail, one massive traffic jam.
The levels of air pollution on the approach roads exceed safe limits. Thus expansion could not be permitted, as would exceed legal limits on air pollution, never mind the contribution to CO2 and global warming.
But rest assured, Heathrow does care about the environment. They have wood-fired stoves to warm Terminal 3, or at least wood-fired heating.
