The Committee on Climate Change (CCC) published a report on Friday 9 July which found that deep decarbonisation across the existing housing stock to nearly zero residual emissions is possible. The report, commissioned by the CCC and produced by Element Energy and UCL, found that, under its ‘Further Ambition’ scenario, the government could abate 95% of direct emissions from existing buildings by 2050 at a cost of around £13bn/yr. This scenario includes 20mn individual heat pumps and hybrid heat pumps and more than 5mn homes on district heating.
