To ask the Minister of State, Department for Transport what modelling the Government has done on the economic and environmental effects of a third runway at Heathrow; and if he will place a copy in the Library of the outcomes of such modelling. (313003)

The Department for Transport published its latest assessment of the economic and environmental effects of a third runway at Heathrow in “Adding Capacity at Heathrow Airport—Impact Assessment” in January 2009. The publication coincided with the Secretary of State for Transport’s announcement of his policy decisions on the future development of Heathrow airport. Copies of the published documents, and earlier technical reports on the environmental modelling, have all been deposited in the Library.
