I have been asked to reply.
DEFRA’s Market Transformation Programme estimates that by using only compact florescent lamps (CFLs) UK homes could yield annual savings in the order of just under 3 MtCO2, some 2 per cent. of the total CO2 emissions from UK households in 2006.
European member states agreed on 8 December 2008 a draft measure under the Eco-design of the Energy-using Products Directive to set mandatory efficiency requirements on light bulbs that will result in a phase out of incandescent lamps by September 2012 and removal of the least-efficient halogen lamps by 2016. After this date, only the most efficient halogen lamps, CFLs and lamps based on emerging light emitting diode technologies will remain.
The European Commission is developing a further measure to set efficiency requirements on directional spot lamps commonly used in UK homes.
