§ Mr. Randall
To ask the Secretary of State for Transport (1) what research he has commissioned on methods of maintaining levels of nitrogen dioxide around Heathrow Airport within EU limits;
(2) whether a third runway at Heathrow Airport would remain an acceptable option in the forthcoming Aviation White Paper in the event that relevant pollutants could not be contained within EU limits; 
(3) what assessment his Department has made of the action plan to minimise emissions from Heathrow Airport which BAA plc was required to produce as a condition of the planning permission for the fifth terminal. 
§ Mr. McNulty
The Government has reviewed a wide range of evidence, including information contained within the BAA pic Air Quality Strategy and Action Plan, in considering the future development of Heathrow. The Government remains of the view that a new runway at Heathrow could not be considered unless it could be confident that levels of all relevant pollutants could be consistently contained within EU limits. Final decisions will be announced in the forthcoming air transport White Paper.
