To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to the Answer of 18 May 2023 to Question 184913 on Government Departments: Aviation, what the baseline data is for the emissions from domestic business flights in 2017-18; and what the is source for that data.

The baseline data for emissions from domestic flights in the 2017 to 2018 financial year will be published in the Greening Government Commitments (GGCs) annual report for 2021 to 2022, which we will publish this year. 2021-25 targets are set against a new baseline year of 2017 to 2018, which more accurately reflects the current government estate and ensures we build on the considerable progress already achieved. The GGCs reporting requirements sets out the process for baseline setting.
