§ Mr. Andrew TurnerTo ask the Secretary of State for Transport what methods he uses to estimate the relative environmental impact of journeys by(a) train, (b) aeroplane and (c) ferry; and if he will make a statement. [85088]
§ Mr. JamiesonEnvironmental impact assessments of different transport modes take into account the full range of environmental matters, including air pollutants, CO2 emissions and noise, the length of journeys and the quantity and type of fuel consumed. There is also consideration of other local emissions sources, background levels of air pollution in the area and the extent to which emissions from the transport modes in question can be dispersed. The impact of infrastructure on the local environment is also assessed.
