Sister airlines British Airways and Aer Lingus have agreed a supply deal for sustainable aviation fuel (SAF) to power their flights from San Francisco.
The two IAG-owned carriers will benefit from a multi-year agreement with renewable fuels company Aemetis to supply SAF for their San Francisco flights from 2025.
Under the deal, IAG will purchase 78,400 tonnes of SAF over seven years for BA and Aer Lingus flights departing from the Californian city.
Jonathon Counsell, head of sustainability at IAG, said: “SAF is key to decarbonising aviation and IAG has - to date - committed $865 million in SAF purchases and investments.
“We see great potential to develop a long-term partnership with Aemetis who is at the cutting edge of producing low carbon biofuels from sustainable wastes.”
Earlier this year, British Airways said it had become the first airline to use SAF on “a commercial scale” after receiving its first delivery through an agreement with UK-based supplier Phillips 66.
Aer Lingus has already signed a separate supply agreement to buy SAF from another US-based renewable fuels specialist Gevo, which will also be used to help power flights from Los Angeles and San Francisco.
Eric McAfee, chairman and CEO of Aemetis, said: “Sustainable aviation fuel continues to be shown to be a great solution to decarbonise aviation and can be used in existing aircraft engines.
“IAG is continuing to take a leadership position by the conversion of their fuel supply to the use of sustainable fuels.”
