Lower-carbon jet fuel mandate comes into force

Flights from UK airports must use a minimum amount of lower-carbon jet fuel from Wednesday, with the introduction of the sustainable aviation fuel (Saf) mandate. By law, Saf must make up at least 2% of all jet fuel used in flights in 2025. The percentage will rise annually, reaching 10% in 2030 and 22% in 2040. The Department for Transport described the requirement – which applies to all aviation fuel suppliers – as “ambitious but achievable”. Where suppliers cannot directly provide the required amount of Saf, they can purchase certificates from other companies which have provided more than needed. Alternatively, they can pay the Government £4.70 per litre provided under the required level. Non-compliance risks civil penalties being imposed. Saf is seen as vital to reduce the aviation industry’s carbon emissions. The fuel is made from sources such as agricultural waste and used cooking oil, meaning its production involves using about 70% less carbon than conventional jet fuel, which is a type of kerosene. It can be blended with kerosene at up to 50% without the need for aircraft engine modifications.<br/>
