Lighting: Carbon Emissions

Volume 491: debated on Wednesday 22 April 2009

To ask the Secretary of State for Environment, Food and Rural Affairs what estimate his Department has made of the effect on the level of UK carbon dioxide emissions of the replacement of traditional light bulbs by energy efficient light bulbs in (a) domestic and (b) non-domestic properties. (268151)

The Government have a number of measures in place that have increased, and will continue to increase the market penetration of the most energy efficient lamps, particularly compact fluorescent lamps, in replacement of energy-inefficient incandescent lamps.

The Government’s Market Transformation Programme (MTP) estimated the resultant savings of these policies in its Policy Analysis and Projections publication of July 2008—available at:

The combined annual savings resulting from these actions was 4.2 MtCO2 per annum by 2020 for commercial and street lighting, and 4.6 MtCO2 per annum in 2020 for domestic applications.

Through a regulation under the Framework Directive for the Eco-design of Energy-using Products (EuP), to be formally adopted in April 2009, inefficient incandescent lamps for household use will be taken off the market in stages between September 2009 and 2012. Analysis based on MTP modelling indicates that this action will result in savings of over 1 million tonnes of CO2 per annum by 2020 on top of the measures already in place.

A separate, recently-adopted regulation on tertiary lighting under the EuP Framework which, by removing the least efficient office and street lighting products from the market, will deliver a further 1 million tonnes of CO2 savings by 2020.
