(The Connexion) Airlines will be required to use 1% of bio-jet fuel from 2022. It is 80% less polluting than normal fuels, but could lead to more expensive flight tickets — France’s parliament is in the process of adopting legislation through its draft 2021 budget that will require any airliner refuelling in the country to use at least 1% renewable bio-jet fuel. Bio-jet fuels are made from waste or vegetable or animal oils and they emit up to 80% less CO2 than fossil-based kerosene, which is currently used by airliners. France plans to increase this obligation to 2% of all aviation fuel by 2025, 5% by 2030 and 50% by 2050. Globally, only around 0.6% of the jet fuel used to power aircraft is sustainable biofuel, aviation news network Runway Girl states.
