Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, with reference to the figure of 275 tonnes for CO2e emissions from domestic flights in 2021-22 on page 68 of his Department's Annual Report for 2021-22 and to the figure of 230 tonnes for CO2e emissions from domestic flights on page 43 of his Department's Annual Report for 2022-23, what the evidential basis is for the statement on that page of the Annual Report for 2022-23 that CO2e emissions from domestic flights in 2022-23 had increased from 2021-22.

The two sections in the respective annual reports referenced use different methodology and are not comparative.

The chart on page 41 of the 2022-23 annual report provides comparative Scope 3 emission data for all official domestic business travel from 2017-18 (baseline) to 2022-23 (showing a reduction of 72% compared to baseline).

Page 43 of the 2022-23 annual report provides commentary on the broader trends between the two years.
