Greenhouse Gas Emissions

Volume 492: debated on Tuesday 12 May 2009

To ask the Secretary of State for Energy and Climate Change what estimate he has made of the proportion of UK (a) carbon dioxide and (b) other greenhouse gas emissions arising from (i) cars, (ii) buses, (iii) all road vehicles, (iv) trains, (v) aviation and (vi) shipping in each of the last 10 years. (266631)

The latest 2008 provisional estimates of greenhouse gas emissions were published on 26 March 2009. DEFRA is currently publishing the DECC climate change statistics; the 2008 Final UK Greenhouse Gas Emissions National Statistics may be found at the following web address:

The proportion of UK (a) carbon dioxide and (b) other greenhouse gas emissions arising from (i) cars, (ii) buses, (iii) all road vehicles, (iv) trains, (v) domestic aviation and (vi) domestic shipping in each of the last 10 years, are shown in the following table. These figures have been compiled from the DECC Provisional UK Greenhouse Gas Emissions National Statistics. These percentages are calculated on an ‘End User’ basis, i.e. the emissions are reallocated from the production and distribution of energy to the users of that energy.
