Sustainable Aviation Fuel Market size was valued at US$ 240.2 million in 2021 and US$ 3,264 million in 2024 with a growth rate of 138.7% during the historic years. In 2025, the market valued at US$ 6,332 million and expected to witness a CAGR of 44.8% over the forecast period (2025-2031) and is estimated to be valued at US$ 58,401 million in 2031.

The market refers to the global industry focused on the production, distribution, and utilization of aviation fuels derived from renewable and sustainable sources such as biomass, waste oils, municipal solid waste, and advanced feedstocks. SAF is designed to serve as a direct substitute or blend for conventional jet fuel, meeting stringent aviation safety and performance standards while significantly reducing lifecycle greenhouse gas emissions. The market encompasses technological processes, supply chain logistics, regulatory frameworks, and commercial adoption pathways driving the transition toward low-carbon aviation.

The market is experiencing rapid growth as governments, airlines, and energy companies increasingly prioritize carbon reduction in the aviation sector. With aviation accounting for a significant share of global greenhouse gas emissions, SAF has emerged as a critical solution for decarbonizing air travel. Supported by international policies, such as CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation) and net-zero commitments by leading airlines, demand for SAF is rising. Market expansion is further fueled by advancements in feedstock diversification, partnerships between fuel producers and aviation stakeholders, and large-scale investments in refining capacity. However, high production costs, limited availability of sustainable feedstocks, and supply chain challenges remain key barriers, highlighting the need for technological innovation and supportive government incentives to ensure long-term scalability.

Facts & Figures

• In fact, Global SAF production doubled from 300 million liters in 2022 to about 600 million liters in 2023.
• In 2024, SAF output reached around 1 million tonnes, equal to 1.3 billion liters.
• SAF accounted for only 0.3% of total global jet fuel consumption in 2024.
• SAF represented approximately 11% of global renewable fuel supply in 2024.
• By 2035, global SAF supply is expected to reach 18 million tonnes, while demand will exceed that by more than 23 million tonnes.
• More than 40 airlines have committed to using about 16 billion liters of SAF by 2030.

Key Developments

• In July 2025, Avfuel Corporation has expanded its sustainable aviation fuel (SAF) network with the addition of its Denver Terminal, establishing the first SAF supply point in the central United States.
• In April 2025, Gevo made an agreement with Dublin-based Future Energy Global (FEG), aimed at helping airlines and corporations significantly cut their carbon emissions. Under the deal, FEG will purchase Scope 1 and Scope 3 carbon abatement credits linked to 10 million gallons annually of Gevo’s Sustainable. Aviation Fuel (SAF) from its forthcoming ATJ-60 facility.
• In March 2024, Avfuel Corporation announced the delivery of sustainable aviation fuel (SAF), marking an expansion of SAF accessibility into a new region of the United States. Supporting this initiative, Overland Aviation provides comprehensive services with a focus on safety, efficiency, and affordability. Its offerings include U.S. Customs clearance (conveniently co-located within the FBO facility), 30-minute quick turns, full ground handling solutions, aircraft maintenance, and FAA Part 135 Air Charters.

Sustainable Aviation Fuel Market Segmentation

Based on the manufacturing technology

• Hydro processed Fatty Acid Esters and Fatty Acids – Synthetic Paraffinic Kerosene (HEFA-SPK)
• Fischer Tropsch Synthetic Paraffinic Kerosene (FT-SPK)
• Methanol-to-Jetfuel (MTJ)
• Alcohol to Jet SPK (ATJ-SPK)
• Others

Hydro processed Esters and Fatty Acids – Synthetic Paraffinic Kerosene (HEFA-SPK) is anticipated to lead the Sustainable Aviation Fuel market due to its technological maturity and large-scale commercial viability. HEFA-SPK is currently the most widely approved and adopted pathway for SAF production, offering seamless compatibility with existing aircraft engines and fueling infrastructure. It utilizes readily available feedstocks such as used cooking oil, animal fats, and vegetable oils, ensuring consistent supply and cost-efficiency compared to other advanced pathways. Major producers like Neste and World Energy have already scaled up HEFA-SPK facilities, supported by strong policy incentives and airline offtake agreements, driving its global dominance.

Based on the blending capacity

• Below 30%
• 30% to 50%

The below 30% blending capacity segment is anticipated to lead the market, primarily because it aligns with current regulatory requirements and airline operational standards. Most aviation authorities, including ASTM International, have certified SAF for blending with conventional jet fuel up to 50%, but most airlines and airports are currently adopting blends below 30% due to cost constraints and limited supply availability. This blending range provides a practical balance between reducing lifecycle emissions and maintaining fuel affordability, while also ensuring seamless engine compatibility. Government mandates, such as the EU’s SAF blending targets starting at low percentages, reinforce the dominance of this segment in the near term.
