Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if he will make an estimate of the reduction in emissions in tCO2 due to the introduction of the Clean Heat Market Mechanism in each year from 2025 to 2030.

The impact assessment published alongside the laying of the Draft Statutory Instrument for the Clean Heat Market Mechanism estimates the net greenhouse gas emissions savings at the initial target level at 0.03MtCO2e annually in the years 2025 through to 2028 and 0.04MtCO2e in both 2029 and 2030. The majority of emissions savings relating to heat pump deployment over this period are attributed to other policies, such as the Boiler Upgrade Scheme.
