Japan Airlines is using a sustainable aviation fuel, or SAF, on one of its international flights during a week-long trial.
SAF accounts for 11 percent of the fuel on flight JL6 from Tokyo's Haneda Airport to New York City. The trial started on Thursday.
The carrier's goal is for SAF to make up 1 percent of the fuel burned on all its flights by 2025. The ratio is slated to rise to 10 percent by 2030.
Nishioka Momoko of Japan Airlines said, "Naturally, it is important to devise daily operations and update equipment.
But it is essential to make the fuel a sustainable one, such as SAF, in order to achieve carbon neutrality."
SAF is made from plants and waste oil. It can reduce CO2 emissions by up to 80 percent compared to conventional jet fuels.
The Japanese government wants SAF to account for 10 percent of the fuel used at the country's airports by 2030.
