To ask the Secretary of State for Business, Energy and Industrial Strategy, pursuant to the Answer of 23 December 2016 to Question 57882, what assessment he has made of the effect of the decrease in the number of energy efficiency measures installed in homes since January 2014 on the Government's commitment to reduce carbon emissions.
The energy efficiency measures installed in homes since January 2013 as a result of Government initiatives were delivered via the Energy Company Obligation (ECO – including Affordable Warmth), Cashback, the Green Deal Home Improvement Fund (GDHIF) and the Green Deal.
The provisional estimated lifetime carbon savings of measures installed through these schemes (excluding Affordable Warmth) to the end of September 2016, was between 28.5 - 30.0 MtCO2 with provisional estimated lifetime energy savings between 115,153-121,534 GWh.
The majority of these measures were delivered through the ECO scheme. Government sets the carbon savings thresholds which obligated ECO suppliers must meet over the lifetime of the scheme but it is up to suppliers to determine when, and how, they achieve these savings over the reporting period. This means that the numbers and types of measures installed from year to year can vary without reducing the overall carbon saved.
