To ask the Secretary of State for Business, Enterprise and Regulatory Reform what proportion of national aggregate carbon dioxide emissions emitted were attributable to energy consumption within buildings in each of the last five years; and what proportion of that figure comprised emissions from private households. (202996)

I have been asked to reply.

The information requested is provided in the following table. It is not possible to separate energy consumption for the purposes of heating and lighting in the industrial sector from energy consumption for other purposes (e.g. machinery, incineration). Therefore, the numbers given apply only to the commercial, public and residential sectors.

More details on the sources of UK CO₂ emissions can be found in The Annual Report to Parliament 2007.

The total CO₂ emissions from buildings accounted for about 40 per cent. of total UK CO₂ emissions (26.4 per cent. from the residential sector) in 2006.

Emissions figures are provided on an ‘end user’ basis, while emissions from power stations are allocated to the buildings in which the electricity generated is consumed.
