The International Air Transport Association (IATA) recently released updated estimates for Sustainable Aviation Production (SAF). The revised estimates show that the growth of SAF is slower than expected. As per the IATA, the production reached 1 million tonnes in 2024. Although the number reflects twice the increase in SAF produced in 2023 (0.5 million tonnes), it falls short of the expected 1.5 million tonnes earlier predicted.
SAF Production and Global Impact
SAF currently represents just 0.3% of global jet fuel production and 11% of global renewable fuel. The slow growth has raised concerns within the aviation industry. IATA Director General Willie Walsh stressed the importance of for governments to phase out fossil fuel subsidies. He also called for policies that encourage renewable energy production including SAF.
He pointed out that although SAF volumes are growing, the progress is disappointingly slow. He also highlighted that the airline industry is ready to invest in SAF. However, he noted that investors need long term assurances before committing funds.

IATA’s Vision for Aviation Decarbonization
IATA stresses that decarbonizing aviation is part of the broader global energy transition. Marie Owens Thomsen, IATA’s Senior Vice President for Sustainability, explained that renewable fuel refineries will produce multiple fuels for various industries. SAF will only account for a small portion of this production.
To meet the net-zero emissions goal by 2050, IATA predicts that 3,000 to 6,500 renewable fuel plants will be required. The plants that will be established will need annual investments of around $128 billion. In comparison to investments required for wind or solar energy, this amount is far less.

Key Measures for SAF Expansion
IATA has proposed three key measures to accelerate SAF production:
- Increase Co-Processing: Expanding the use of renewable feedstocks at existing refineries could save up to $347 billion by 2050.
- Diversify SAF Production: Scaling production using methods like Alcohol-to-Jet and Fischer-Tropsch could boost SAF volumes.
- Create a Global SAF Accounting Framework: Establishing a registry would ensure transparent SAF purchases and prevent double-counting.
