I am grateful to my right hon. Friend for mentioning Cranfield University, because I recall being asked to dig the first turf in the building of that facility about a decade ago. It just shows what can happen in 10 years. Does he agree that we need to harness the power of consumers? Some low-cost airlines give consumers the opportunity to carbon offset, but Flybe does not. Will he join me in encouraging airlines to give consumers at least the option to offset?
