• Increasing number of flights at Heathrow to be powered by sustainable aviation fuel (SAF) helping cut carbon emissions • Team Heathrow on track to be one of world's largest SAF users in push to get to at least 10% usage by 2030 • £38m fund incentivising airlines to make the switch and power their aircraft in part by SAF • High cost and low production volumes remain key challenges for SAF – policymakers can provide more certainty and unlock private investment and drive down the cost curve Greener, cleaner jet fuel has become a hot commodity at Heathrow as the airport embarks on the second year of its Sustainable Aviation Fuel incentive scheme. In 2022 Heathrow launched a world first – an airport SAF incentive programme which aimed to cover up to 50% of the extra cost, making the fuel more affordable for airlines to use. With last year’s scheme oversubscribed, Heathrow is now aiming to triple the percentage used in 2023 to approximately 1.5%, putting the airport on course to be one the world’s largest users of SAF this year. Participants of the scheme include IAG, Virgin Atlantic, United Airlines, Air France, KLM and JetBlue. SAF is a proven technology that reduces carbon emissions by up to 70% compared with traditional jet fuel. It can be made from a variety of sources, including waste, animal fat and cooking oil. SAF can work in existing aircraft without the need for technical modifications, and with advancements in aircraft technology like electric or hydrogen-powered flight still some way from commercial implementation, SAF is the key to unlocking material reductions in carbon today.
