The question

To ask the Secretary of State for Defence, pursuant to the answer of 18 November 2025, to Question 88284, on Military Aircraft, what is the aggregate volume of CO2 emissions that have been reported for domestic and overseas Ministerial flights on the Envoy and Voyager since July 2024; and what was the aggregate cost of carbon credits for those flights.

Answered by Luke Pollard

The total volume of CO2 emissions in Tonnes (TCO2) and the cost of carbon credits of the flights for the duration of 1 July 2024 - 31 December 2024 is listed below.

UK Emissions Trading Scheme

240.285 TCO2

£12,975.38 Carbon credits including VAT

EU Emissions Trading Scheme

237.787 TCO2

£17,120.66 Carbon credits including VAT

TOTAL UK and EU Emissions Trading Scheme

478.072 TCO2

£30,096.04 Carbon credits including VAT

The same data is not available for 1 January 2025 - 31 December 2025 as it has not yet been released by EuroControl. The Ministry of Defence will not purchase carbon credits prior to establishing the total TCO2 figure for this duration. The total cost will not be available until 31 March 2026.
