Lighting Grant Shapps To ask the Secretary of State for Energy and Climate Change how many of the 100 million (a) free and (b) subsidised low-energy light bulbs which the Government undertook to provide under the Carbon Emissions Reduction Target have been distributed. Joan Ruddock The Government have not undertaken to distribute any particular number of low energy lamps under the Carbon Emissions Reduction Target (CERT). Energy suppliers may choose to meet their carbon saving obligation through any mix of approved measures. During the first three quarters of CERT (April to December 2008), suppliers reported to the scheme administrator, Ofgem, that they had distributed 120.6 million low energy lamps.
