Heathrow third runway won't make pollution worse, MPs told

Airport chief tells Commons committee that expansion would not increase number of cars due to planned railway development

Heathrow airport has said that a new runway will not increase the number of cars on the roads or make air pollution any worse than in central London, because public transport access to the airport will be greatly improved.

The airport, which currently operates over 750,000 flights a year, was backed in July for a third runway by the Davies commission.
