An evaluation of the predecessor scheme to the Carbon Emissions Reduction Target reported in December 2008, and found it to be very effective. Ofgem administrate CERT on the Government's behalf, publishing quarterly updates of suppliers' progress towards targets. Ofgem accredit the carbon score of schemes where suppliers meet the terms of the operational guidance, including auditing and reporting requirements. CERT has been focussed around measures which deliver long lived savings, namely insulation. We estimate that the measures delivered under CERT will deliver lifetime savings of some 185 Mt CO2 by April 2011. An evaluation of the scheme will be undertaken in 2011.A full public consultation was held on proposals for the Community Energy Saving Programme (CESP) from February to May 2009 and it came into effect from September 2009. The CESP impact assessment following the consultation estimated that the scheme will deliver some 2.9 Mt CO2 over the lifetime of the measures installed. We are currently undertaking an evaluation of the CESP, which will be complete in March 2011.
