Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, pursuant to the Answer of 13 February 2025 to Question 29022 on Ministers: Aviation, what the cost-metric is by which carbon offsetting is calculated; and if he will place a copy of the EDF contract in the House of Commons Library.

Carbon offsetting costs are determined by the tonnes of carbon dioxide equivalent (tCO2e) that are being offset, multiplied by the cost per tonne of CO2e from the Certified Emissions Reduction offsets provided by EDF under the framework contract. These costs can fluctuate based on the timing of purchase, as market trading demands affect the price.

The calculation metric used indicates that 1 kilogram of aviation fuel burned results in approximately 3.15 kilograms of CO2 emitted.

The Cabinet Office uses the HMG Crown Commercial Services (CCS) RM6251 Energy Supply Framework (Additional Services) with EDF for offsetting these emissions. For more information, please refer to the following link: https://www.crowncommercial.gov.uk/agreements/RM6251.
