IATA Study Confirms that SAF Technology Rollout is Main Bottleneck to Net Zero, not Feedstock Availability

Published by Todd Bush on September 23, 2025

Geneva - The International Air Transport Association (IATA), in partnership with Worley Consulting, has published a study demonstrating that sufficient sustainable aviation fuel (SAF) feedstock exists to enable the airline industry to achieve net zero CO2 emissions by 2050. All feedstocks considered meet stringent sustainability criteria and do not lead to changes in land use.

Airlines will need 500 million tonnes (Mt) of SAF to achieve net zero carbon emissions by 2050, as outlined in the IATA Net Zero Roadmaps.

“We now have unequivocal evidence that if SAF production is prioritized then feedstock availability is not a barrier in the industry’s path to decarbonization. There is enough potential feedstock from sustainable sources to reach net zero carbon emissions in 2050. However, this will only be accomplished with a major acceleration of the SAF industry’s growth. We need shovels in the ground now,” said Willie Walsh, IATA’s Director General.

“The report highlights the local and regional opportunities for SAF production to create jobs, stimulate economies and support energy security goals. Governments, energy producers, investors, and the aviation sector must work together, de-risk investment, and accelerate rollout. Policy certainty and cross-sector collaboration are essential to unlock the scale we need. The time to act is now—delays will only make the challenge harder,” said Marie Owens Thomsen, IATA’s Senior Vice President Sustainability and Chief Economist.
