To ask the Secretary of State for Transport what estimate she has made of the UK volume of carbon dioxide emissions from aviation in (a) 2006 and (b) 2007; and what estimate she has made of the projected volume of carbon dioxide emissions from aviation in (i) 2008, (ii) 2009, (iii) 2010 and (iv) 2011.

The Department for Transport published forecasts of UK aviation carbon dioxide emissions in November 2007 in 'UK Air Passenger Demand and CO2 Forecasts'. This can be viewed at:


Outturn UK aviation carbon dioxide emissions for 2006 were published in January this year by Defra and can be viewed at:


These data show that UK aviation accounted for 37.9 MtCO2 in 2006. Outturn emissions data for 2007 will not be available until early 2009.

Outturn emissions are calculated from aviation bunker fuel consumption data, which are closely related to fuel used on departing flights. To ensure consistency with historic reported totals, and to avoid double-counting carbon dioxide emissions, DfT's forecasts reflect emissions from all domestic and international flights departing from UK airports. DfT forecasts for 2007-11 are shown in the following table:

UK Aviation emissions of carbon dioxide
(MtCO 2 )
2007 39.0
2008 39.6
2009 41.0
2010 42.0
2011 43.0
