Pure-play renewable fuels producer EcoCeres has signed a multi-year partnership agreement to supply British Airways with sustainable aviation fuel ( SAF ) that is expected to help the UK’s flagship carrier reduce lifecycle carbon emissions of approximately 400,000 metric tonnes, compared with use of the same volume of conventional jet fuel.

This reduction is equivalent to the total emissions of flying approximately 240,000 economy class passengers on return flights between London and New York.

EcoCeres will provide SAF produced from 100% waste-based biomass feedstock, such as used cooking oil ( UCO ), to the airline, which British Airways has committed to powering 10% of its flights with SAF by 2030. This SAF has the potential to provide a lifecycle carbon reduction of up to 80% compared with the traditional jet fuel it replaces.

“In 2024 alone, SAF accounted for 2.7% of British Airways’ total fuel use and is contributing to our achievement of a 13% reduction in our carbon intensity since 2019,” says Carrie Harris, the airline’s director of sustainability. “That’s why this new agreement with EcoCeres is so exciting – it’s another important step forward on our journey to reach net-zero carbon emissions by 2050.”
