Global production of Sustainable Aviation Fuel (SAF) is projected to double to 2 million tons in 2025, the International Air Transport Association (IATA) has said, though the industry body warns that the figure still represents less than 1 percent of aviation’s total fuel consumption.
IATA’s Director General, Willie Walsh, made the disclosure during the association’s 81st Annual General Meeting in New Delhi. He acknowledged the progress but stressed that the scale remains far too small to make a meaningful dent in aviation’s carbon emissions.
“While it is encouraging that SAF production is expected to double to 2 million tons in 2025, that is just 0.7 percent of aviation’s total fuel needs,” Walsh said. “And even that relatively small amount will add $4.4 billion globally to the fuel bill. The pace of progress in ramping up production and gaining efficiencies to reduce costs must accelerate.”
The aviation industry has been under mounting pressure to decarbonize, with countries introducing net-zero targets as part of their energy transition goals. SAF—produced from sustainable feedstocks like used cooking oil and agricultural waste—has been identified as a critical lever to cut aviation emissions without needing to overhaul current aircraft technology.
However, its limited supply and high cost remain major bottlenecks.
Call for Policy Reform and Renewable Energy Access
According to IATA, the success of SAF hinges on two critical needs: increasing global renewable energy production and securing dedicated access for SAF producers.
“Advancing SAF production requires an increase in renewable energy production from which SAF is derived,” IATA said. “Secondly, it also requires policies to ensure SAF is allocated an appropriate portion of renewable energy production.”
Walsh further emphasized the need for coordinated government policy, saying, “Sufficient government measures, including the implementation of effective policies, are needed to meet decarbonization efforts.”
He also pointed to the importance of the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), an initiative launched by the International Civil Aviation Organization (ICAO). Under CORSIA, international airline operators are required to purchase and cancel emissions units to offset growth in carbon emissions above 2019 levels.
Revenue Blockages Add to Industry Pressure
Aside from fuel-related concerns, IATA also raised concerns over the continued blocking of airline funds by several governments. As of the end of April 2025, $1.3 billion in airline revenues remain stuck in various countries, down from $1.7 billion reported in October 2024—a 25 percent improvement, but still a significant strain on airline liquidity.
“These blockages violate international treaties and compromise the financial stability of airlines,” Walsh said. “Ensuring the timely repatriation of revenues is vital for airlines to cover dollar-denominated expenses and maintain their operations.”
He warned that the delays increase exchange rate risks and threaten airlines’ ability to maintain vital air connectivity, particularly in economies that depend heavily on international air transport.
“Economies and jobs rely on international connectivity. Governments must realize that it is a challenge for airlines to maintain connectivity when revenue repatriation is denied or delayed,” he added.
The Regional Divide
While Walsh praised parts of the Middle East for their aviation progress, he cautioned that conflicts, sanctions, and closed airspace in the broader region continue to undermine industry recovery.
“Conflicts, sanctions & closed airspace don’t just ground planes — they stall economies,” he said in a statement shared via IATA’s social media handle.
As the aviation world convenes in New Delhi, the SAF conversation remains a top agenda item. IATA is urging global stakeholders to harmonize regulatory frameworks, enhance safety oversight, and tackle economic policies that continue to choke airline growth and sustainability efforts.
Although the doubling of SAF output offers a glimpse of hope, the road to aviation decarbonization remains steep. However, IATA’s message is that governments must act faster, producers must scale up, and the industry cannot afford to move at its current pace.
