Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what steps his Department is taking to reduce the amount of fuel dumped by airborne RAF aircraft.

Not all aircraft have the capability to jettison fuel. Of those that do, jettisoning of fuel is not a routine occurrence and is used to reduce the weight of the aircraft or improve control; for example, in association with an emergency.

Data on jettisoning fuel is not held centrally and could be provided only at disproportionate cost.
