Exhaust Emissions: Aviation

Volume 458: debated on Monday 19 March 2007

To ask the Secretary of State for Environment, Food and Rural Affairs (1) what the carbon emissions were of international flights to and from the UK in each of the last five years; (126454)

(2) what the levels of carbon dioxide emissions were from internal domestic flights in the UK in each of the last five years;

(3) what the level of carbon emissions was from the aviation industry in each of the last five years.

The following table shows emissions of carbon dioxide from domestic UK flights, international flights leaving UK airports and total emissions from all UK aviation, in million tonnes of carbon dioxide (MtCO2) in each year from 2000 to 2005. Emissions from flights arriving in the UK are not estimated.

1 Definition of the UK excludes UK overseas territories.

International aviation is reported as an information item in the UK greenhouse gas inventory but does not, by international agreement, count towards national totals under the Kyoto Protocol.

The impact of aviation on climate change is not limited to CO2 emissions. Although there is need for further research, the Intergovernmental Panel on Climate Change has estimated that the total climate change impact of aviation is between two and four times greater than that of its CO2 emissions alone.
