IAG increased SAF usage to 3.3% in total fuel volumes in 2025

International Airlines Group (IAG) said the company increased its sustainable aviation fuel (SAF) usage to 3.3% of the total fuel volumes in the year.

The group said it paid a premium of over €222m for the use of SAF in 2025, double from the 2024 levels as it significantly increased SAF usage during the last year.

Overall, the company reported record revenue of €33.2bn during 2025, witnessing an increase pf 3.5% year-over-year from 2024. While passenger revenues were up by 2.5%YoY, significant increase in the came under other revenue which saw a 16%YoY increase to €3bn.

This growth came from IAG’s MRO business and loyalty programmes. However, interestingly, the IAF said significant aspects of other revenue were mainly driven by the sale of certain carbon attributes, available due to the group’s investment in SAF above mandates.

During the year, IAG joined the oneworld alliance and Breakthrough Energy Ventures investment fund as an investor. As part of the arrangement, IAF committed to provide €21m ($25m) to the investment fund. At 31 December 2025, the remaining commitment was €17m ($20m).

Overall, the company has plans to increase the use of SAF to 10% by 2030 and to 70% by 2050. The company said its existing and future fleet assets align with the long-term fleet plans to achieve its Flightpath Net Zero climate strategy.

“All aircraft in the fleet, and those due to be delivered in the future, have the capability to utilise SAF in their operations without impediment,” it said.
