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

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.

The study also identified significant barriers in using that feedstock for SAF production, namely:

• The slow pace of technology rollout that would enable SAF to be produced from varied sources. Currently the only commercially scaled SAF production facilities use HEFA technology, for example converting used cooking oil into SAF.
• Competition with other potential users of the same feedstock. Policies allocating biomass feedstock to hard-to-abate sectors such as aviation must be prioritized.

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. This can be achieved from two main sources:

• Biomass: This has the potential to produce more than 300 Mt of bio-SAF annually by 2050. Some of this potential could be limited by use for competing sources. This potential could be expanded by unlocking additional feedstocks or through efficiency gains and technology improvements over intervening decades.
• Power-to-liquid (PtL): This will be required to reach 500 Mt of SAF production annually by 2050. Maximizing the volumes of cost-effective bio-SAF will reduce the pressure on e-SAF to bridge the gap.

In all cases, to maximize SAF output, it will be essential to improve conversion efficiencies, accelerate technology rollout, enhance feedstock logistics, and invest in better infrastructure required to scale up commercial facilities across all regions.

"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.

Key findings from the report include:

• There are sufficient sustainable feedstocks and SAF production technologies to decarbonize aviation and meet the net zero carbon emissions goal by 2050.
• With the right policies and investments, more than 300 Mt of SAF from biomass feedstocks could be produced annually by mid-century and around 200 Mt from e-SAF.

The main challenges are:

"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.

"With this study it becomes clear that we can make SAF the solution it needs to be for aviation's decarbonization. The potential to turn SAF feedstock into real SAF production is in the hands of policymakers and business leaders, particularly in the energy sector. The conclusion of this study is an urgent call to action. We have just 25 years to turn this proven potential into reality," said Walsh.
