HC Deb 20 November 2002 vol 394 cc178-9W
Norman Baker

To ask the Secretary of State for Transport what the average CO2 emission per air passenger has been in each year since 1990. [80845]

Mr. Jamieson

Information is not available in the form requested. Table 2.8 on page 40 of "Transport Statistics Great Britain 2002" shows that the total contribution by civil aviation to CO2 emissions in the United Kingdom remained steady throughout each year from 1990 to 2000 and comprised 1 per cent. in 2000, the latest year for which data are available.

Norman Baker

To ask the Secretary of State for Transport what estimate he has made of the average carbon dioxide emissions per person per journey from London to Newcastle by(a) air, (b) rail, (c) lorry and (d) car. [81579]

Mr. Jamieson

The estimates are as follows:

kg
(a) Air (average per passenger) 49
(b) Rail (average per passenger) 16
(c) Lorry (average per lorry)
Articulated diesel 403
Rigid diesel 461
(d) Car (average petrol):
Per car 89
Average per passenger 56
(e) Car (average diesel):
Per car 54
Per passenger 34

Estimates are based on a journey distance of 270 miles. In the case of air travel and rail travel, they make no allowance for travel to the airport or railway station. In the case of lorries, it is assumed that fuel consumption for an articulated lorry is 0.35 litres per km, and for a rigid lorry, 0.40 litres per km. Emissions per passenger for travel by car will depend on the size of the vehicle, and the number of passengers. Estimates above are based on an average car and average car occupancy over all journeys of 1.59 passengers per car derived from National Travel Survey in the period 1999–2001.
