Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to the Cabinet Office Freedom of Information Act response with reference FOI2025/12575, published on 5 September 2025. whether Ministerial flights on the (a) Envoy IV, (b) Voyager are carbon-offset.

The Royal Air Force (RAF) report emissions for all domestic and overseas Ministerial flights under the UK, EU and CH Emissions Trading Scheme for the Envoy and Voyager aircraft that are above the 1000T CO2 threshold, to purchase and surrender carbon credits for those flights. The RAF are exempt under the Carbon Offsetting Reduction Scheme (CORSIA) for additional carbon offsetting as they are below the annual 10,000T CO2 emissions threshold.

All Ministerial flights comply with the Department for Transport (DfT) Sustainable Aviation Fuel (SAF) Mandate which requires fuel suppliers to provide ready blended fuel at 2% SAF to 98% Jet A-1 fuel. The RAF is committed to reducing its carbon footprint through the Air Mobility Fuel Efficiencies and Emissions Reduction Programme, the Defence Aviation Net Zero Strategy and compliance with the UK DfT SAF Mandate.
