Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what estimate his Department has made of (a) the projected market price per litre of conventional aviation turbine fuel (Jet A-1) in each year from 2025 to 2040 and (b) the marginal cost difference per litre between conventional aviation turbine fuel and Sustainable Aviation Fuel in each of those years.
The Royal Air Force in conjunction with the Ministry of Defence Directorate Analytics are able to provide an estimated cost of the price per litre of both Conventional Aviation Turbine and Sustainable Aviation Fuel (SAF) in each year from 2025-2040, and the marginal cost difference between them. However, the data in the below table is subject to change dependent on market fluctuation of fuel costs.
The below forecasts are in United States Dollars (USD) per litre and will be subjected to currency conversion, which is changeable. Oil is generally bought and sold on the market in USD.
