Aviation: Carbon Emissions

Volume 502: debated on Wednesday 16 December 2009

To ask the Minister of State, Department for Transport what the average carbon emissions were per UK air passenger in each year since 1997. (306972)

The following table provides estimates of aviation carbon dioxide (CO2) emissions per passenger for all domestic and international air passengers flying from UK airports in each year from 1997 to 2007.

2008 Air Passenger data are available but the 2008 CO2 emissions data will be released in February 2010.

Notes:

1. Domestic aviation includes all departures from UK airports flying to another UK airport. International aviation includes all departures from a UK airport flying to a destination outside of the UK. These will carry both UK and foreign passengers.

2. The aviation CO2 emissions are derived from bunker fuel sales, which broadly equates to all departing aircraft (excluding military aircraft). Therefore the figures in the table do not reflect emissions from surface access nor emissions from airport buildings.

3. Emissions from freighter aircraft have been allocated to passengers in these illustrative figures.

4. The CO2 emissions do not account for non-CO2 climate change effects of aviation emissions.

Source:

Carbon dioxide emissions—AEA Energy and Environment/DECC.

Passengers—Civil Aviation Authority statistics.

The average CO2 per passenger figures in the table have been calculated by dividing total CO2 emissions from departing flights by the number of departing passengers. They do not therefore reflect a weighted average of emissions to account for the relative numbers of flights flying different trip lengths. The level of emissions per passenger will be affected by such factors as load factors, type of aircraft used and fuel efficiency changes.
