Last year, a number of us were on the first transatlantic flight powered by sustainable aviation fuel. This week, the International Airlines Group made its first major purchase of that fuel, but that fuel is coming from the United States and it is important that we have a SAF industry in this country. Will the Prime Minister tell the Treasury and the Department for Transport to accelerate the work that they are doing to put in place the right framework and the right support mechanisms to ensure that we have a SAF industry for our aviation sector for the future?
