Question to the HM Treasury:

To ask the Chancellor of the Exchequer, pursuant to the Answer of 22 July 2019 to Question 277102 on Aviation: Alternative Fuels, if he will make an assessment of the potential merits of introducing tax (a) incentives and (b) disincentives to accelerate the switch to alternative aviation fuels.

In line with international conventions to which the UK is party, the government does not charge fuel duty on commercial aviation fuel, therefore alternative aviation fuels cannot currently be supported through the tax system.

Biofuels are supported outside of the tax system through a market-based certificate trading mechanism called the Renewable Transport Fuel Obligation (RTFO), which has a sharp environmental focus.
