§ Mr. RedwoodTo ask the Secretary of State for Transport what emissions of(a) carbon monoxide, (b) hydrocarbons, (c) oxides of nitrogen and (d) particulates are generated by (i) a four car new DMU train on a normal commuter service, (ii) a new bus on an urban test cycle, and (iii) an average new car on an urban test cycle. [81254]
§ Mr. SpellarThe emissions are shown in the following table. The data for road vehicles are from the 2001 National Atmospheric Emissions Inventory. The data for rail are from a recent study carried out by NETCEN.

g/vehicle km NOx PM CO HC 4 car DMU train 26.75 0.85 8.16 2.51 Urban bus 6.748 0.216 1.625 0.725 Urban car 0.190 0.0058 0.813 0.046 The train emissions are for a Virgin Voyager Class 221 with one power car and three trailer cars. It should, however, be noted that the majority of commuting by train is in London and the south east, where the majority of trains are electric and so have zero local emissions. The car and bus data refer to Euro III standards (ie current standards for new vehicles) at an urban speed. The car emissions are averages, weighted by the proportion of petrol and diesel cars in the fleet. A full environmental comparison would need to incorporate occupancy figures but comparative data per passenger km are not available.
