ICCT study finds tankering could undermine EU SAF mandate
Fuel tankering in commercial aviation is the practice of overfueling with less expensive fuel purchased at one airport to avoid purchasing more expensive fuel at another—in other words, flying with extra fuel on board to save money. Calculating the benefit of tankering is highly flight-specific; extra fuel increases the takeoff mass of the plane, and results in a fuel burn penalty proportional to the flight distance. Nevertheless, the practice is common. Businesses have developed calculators to assist in determining tankering go/no-go benefits, and aircraft manufacturers such as Gulfstream provide guidance as well.
