Mr. Redwood

To ask the Secretary of State for Health what volume of carbon dioxide is emitted per passenger kilometre by (a) low cost airlines, (b) other airlines, (c) UK buses and (d) UK mass transit systems. (110727)

Gillian Merron

I have been asked to reply.

Information on carbon dioxide (CO2) emissions from aviation are not broken down by low cost and other airlines.

Data on CO2 emissions per passenger kilometre from aviation, buses and other mass transit systems (rail and tram/light rail) are shown in the following table:

Carbon dioxide emissions by mode of transport1

Mode

Grams of CO2 per passenger km

Air—long haul2

112

Air—short haul2

148

Bus

95

Rail

36

Tram/light rail3

65

1 Data for air and rail are available in annex 6 of DEFRA’s ‘Guidelines for Company Reporting on Greenhouse Gas Emissions’ (July 2005).

2 ‘Long haul’ refers to average journeys of 5,000nm and ‘short haul’ refers to journeys of 500nm.

3 The tram and light rail estimate is an average for the Docklands Light Rail, Croydon Tramlink and Manchester Metrolink.
