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 impact of phase (a) one, (b) two and (c) three of the Public Sector Decarbonisation Scheme on the level of carbon emissions in public buildings.

Published estimates of carbon savings from Phase 1, 2 and 3 of the Public Sector Decarbonisation Scheme (PSDS) can be found at:

https://www.gov.uk/government/publications/energy-and-emissions-projections-2021-to-2040 (see Public Sector Decarbonisation Scheme impacts in Annex D).

These carbon impacts are forecasts based on economic modelling. There are currently two ongoing evaluations of PSDS, covering process, impact, and value-for-money evaluations of Phases 1 to 3. Findings of these evaluations, including consideration of carbon impacts, will be published in due course.
