Qantas will purchase blended sustainable aviation fuel (SAF) starting in January to help reduce its carbon emissions by around 10 percent for its flights from London. The national carrier has signed an agreement with strategic partner bp to purchase 10 million litres of SAF in 2022 with an option to purchase up to another 10 million litres in 2023 and 2024 for flights from Heathrow Airport. This represents up to 15 percent of Qantas' annual fuel use out of London. The fuel will be produced with certified bio feedstock from used cooking oil and/or other waste products. This is then blended with normal jet fuel. (PHOTO: Qantas)
