Sustainable Aviation Fuel Market Size, Share, Growth and Forecast, 2025-2035

Blending mandates move SAF from niche fuel toward scale

The sustainable aviation fuel market was valued at USD 4.14 billion in 2025 and is projected to increase from USD 5.64 billion in 2026 to USD 37.95 billion by 2035, registering a CAGR of 24.80% during 2025–2035. Demand rests on blending mandates in the EU and U.K., U.S. production tax credits under section 45Z, and airline net-zero pledges for 2050 that leave few other ways to cut emissions on long-haul routes flown by commercial carriers and air forces. Europe held the largest regional share, 62.5% in 2025, because ReFuelEU Aviation set a minimum SAF share at EU airports from that year that rises to 6% in 2030 and 20% in 2035, while Latin America grows fastest at 35.01% a year. The main regulatory change is the synthetic sub-share, which requires power-to-liquid fuel made from green hydrogen and captured carbon from 2030 and reaches 5% in 2035, so a fuel barely produced today becomes a legal requirement.

How is SAF bought, blended and counted?

Fuel suppliers at airports buy SAF from producers, blend it with fossil Jet A or Jet A-1 up to the limits in ASTM D7566, and pass the cost to airlines. Airlines also sign long offtake contracts directly with producers, which give new plants the revenue certainty lenders demand. Output roughly doubled in 2024 and again in 2025, according to IATA, yet SAF still covered less than 1% of global jet fuel demand in 2026, up from 0.3% in 2024.

The market counts HEFA fuel from used cooking oil, tallow and vegetable oils, the renewable share of co-processed refinery jet, and alcohol-to-jet, Fischer-Tropsch and power-to-liquid fuel. It excludes the fossil jet in the blend, CORSIA offsets, book-and-claim certificates without fuel, and renewable diesel sold for road use from the same plants.

Waste-oil HEFA leads while e-SAF and military buyers surge

HEFA-SPK leads by pathway while power-to-liquid e-SAF grows fastest

Based on pathway, the market is categorized into HEFA-SPK, co-processing, alcohol-to-jet (AtJ-SPK), Fischer-Tropsch (FT-SPK) and power-to-liquid (e-SAF). HEFA-SPK led with 85.6% of 2025 value, because large plants run by Neste, Diamond Green Diesel and Montana Renewables switch output between jet and renewable diesel. Power-to-liquid e-SAF grows fastest at 79.31% a year from a very small base, driven by the EU synthetic sub-share of 1.2% over 2030–2031 and 5% in 2035.

Commercial airlines lead end use while military aviation grows fastest

Based on end use, the market is categorized into commercial aviation, business and general aviation, and military aviation. Commercial aviation led with 96.4% of 2025 value, because EU and U.K. mandates fall on fuel uplifted for airline flights and carriers hold most offtake contracts. Military aviation grows fastest at 33.75% a year as air forces test domestically produced fuel for supply security and accept higher prices than airlines for early volumes.

EU quotas, U.S. credits and net-zero deadlines pull SAF

ReFuelEU Aviation sets a rising legal floor for SAF demand

Adopted in October 2023, ReFuelEU Aviation obliges fuel suppliers at EU airports to blend a rising minimum share of SAF. The steps in Annex I of Regulation (EU) 2023/2405 run 2% in 2025, 6% in 2030, 20% in 2035, 34% in 2040, 42% in 2045 and 70% in 2050. Switzerland applied the same rules from Jan. 1, 2026, widening the mandate area. Europe gains most, and each later step multiplies demand that suppliers price into airline contracts.

U.S. production credits reward domestic feedstock instead of mandating blends

The U.S. pays for production rather than ordering blending, through the clean fuel production credit under section 45Z, administered by the IRS, which applies to fuel produced and sold from Jan. 1, 2025, to Dec. 31, 2029, and from 2026 pays only for feedstock grown in the U.S., Mexico or Canada. State credits in California, Illinois, Washington and Minnesota stack on top. North America holds 24.6% of 2025 value and grows at 21.59% a year as federal credits expire before 2035.

Airline net-zero pledges and CORSIA leave few alternatives for long-haul flights

Most carriers have net-zero pledges for 2050, and SAF is the only lever that cuts emissions on long-haul flights before new aircraft arrive. Under ICAO's CORSIA scheme, 130 states take part, and airlines can use SAF to reduce their offsetting duty. Long offtake contracts give producers the revenue certainty lenders demand, which keeps commercial aviation at 96.4% of 2025 value. The effect is long term and global, strongest for carriers with large long-haul networks.

The 2026 jet fuel shock narrows the price gap but strains airline cash

The closure of the Strait of Hormuz in 2026 pushed jet fuel prices and crack spreads sharply higher, and Europe and Africa had drawn 24% and 33% of their jet fuel from the Persian Gulf beforehand. A smaller gap to fossil jet makes SAF easier to sell and raises interest in local supply. Yet airline cash flow suffers, so carriers are likely to buy the mandated minimum and little more in 2026, with a stronger pull once fares recover.

Refinery conversions, ethanol-to-jet and synthetic quotas

Oil majors shift to converting refineries instead of building new plants

Oil majors are turning idle refineries into biorefineries, and Enilive began SAF production at its Gela biorefinery in Sicily on Jan. 22, 2025, as the EU minimum took effect, while TotalEnergies converted Grandpuits near Paris. Converting a site costs far less than a greenfield plant, so HEFA retrofits and co-processing in existing hydrotreaters hold most near-term growth. The shift favors firms that already deliver jet fuel to airports and own blending terminals across 2 or more countries.

Ethanol-to-jet moves from approval to commercial output

LanzaJet reported in November 2025 that its Freedom Pines Fuels plant in Soperton, Georgia, became the first commercial-scale facility to make jet fuel from ethanol. ASTM approved the route in 2016, and the plant opened in January 2024. Ethanol and isobutanol are plentiful in the U.S. and Brazil, so the route escapes the waste-oil ceiling, and Gevo is also developing ethanol-to-jet projects of its own.

Synthetic quotas open an opportunity by giving e-SAF developers a guaranteed buyer

Power-to-liquid fuel is moving from pilots to compliance, yet IATA says global e-SAF capacity in operation or under construction covers only about one-thirtieth of what 2030 mandates require, and around 20 refineries' worth of plants would be needed. The e-fuel supply chain, from electrolyzers to captured carbon, now has a legal buyer, and e-SAF grows at 79.31% a year. Developers that secure cheap renewable power and reach final investment decisions by 2028 capture the 2030–2035 quota demand.

Airport hubs and new producing regions offer an opportunity

Producers, airlines and states now plan supply around single airports. Montana Renewables celebrated the Minnesota SAF Hub in August 2026, one of several state-backed hubs that pair producers with airport demand and cut blending and logistics costs. IATA sees Brazil as a large potential producer from sugarcane ethanol, soybean oil and residues, and Latin America is the fastest-growing region, which favors producers with access to agricultural feedstock.

A threefold price gap and finite waste oils cap SAF supply

SAF costs about three times as much as fossil jet

SAF cost about three times as much as fossil jet in 2025 on IATA's averages, and IATA says EU and U.K. mandates have roughly doubled the cost of SAF to airlines compared with market prices because suppliers pass on compliance costs and fees. Fuel is the largest airline cost, so even a small blend raises fares and squeezes margins. Airlines push back on each fee, and long offtakes with price formulas tied to fossil jet are the main way both sides share the risk.

Finite waste oils concentrate supply risk in one feedstock family

HEFA depends on used cooking oil, tallow and other residues, and those supplies are finite. IATA expects HEFA and co-processing to make up 95% of capacity likely to exist in 2030, with alcohol-to-jet and e-SAF at 2% each and gasification at 1%. Fraud concerns over imported used cooking oil add audit costs for producers and buyers. Mitigation comes from stricter tracing, including RSB certification, which Montana Renewables obtained in November 2025, and from ethanol and oilseed routes.

First-of-a-kind plants ramp up slowly and projects pause

New units miss start dates and run below design, and IATA expects SAF output growth to slow in 2026 for that reason. Several European and U.S. projects have been paused as renewable diesel margins fell, and some HEFA lines switched back to road diesel when credits favored it, leaving suppliers facing quota deadlines to pay more for imports. Producers respond with phased capacity additions, such as Montana Renewables' capital-efficient expansion announced in September 2026, rather than single large builds.

Green hydrogen costs keep e-SAF behind its legal targets

Power-to-liquid fuel needs large volumes of low-cost renewable electricity, electrolyzers and captured carbon dioxide, and current plans fall short. With capacity at about one-thirtieth of 2030 needs, fuel suppliers risk penalties under the synthetic sub-share, and airlines face higher fees. Mitigation comes from long-term offtakes that lower financing costs, public grants for first plants and sites near cheap wind or solar power in Europe, the Middle East and Latin America.

Europe buys under mandate as Latin America grows fastest

Europe's mandates make the region the anchor buyer

Europe held 62.5% of 2025 value and grows at 24.18% a year. ReFuelEU Aviation and the U.K. mandate, which caps HEFA and sets a separate power-to-liquid obligation, make the region the anchor buyer, and European prices sit above other regions because of compliance fees. IATA notes that European jet fuel output fell 13% in 2025 compared with 2019, so imported SAF matters more. Neste's plants in Finland and the Netherlands and converted refineries at Gela and Grandpuits supply much of the regional demand.

North America is the largest producer, steered by tax credits

North America held 24.6% of 2025 value and grows at 21.59% a year. Montana Renewables, Diamond Green Diesel, World Energy and LanzaJet supply U.S. airlines, and state credits steer fuel to California and the Midwest. The SAF Grand Challenge, launched by the Departments of Energy, Transportation and Agriculture in September 2021, set the long-run frame, while 45Z credits run to 2029. Growth trails Europe because federal support expires before the forecast ends.

Asia Pacific builds a second demand center on national blending targets

Asia Pacific held 9.2% of 2025 value and grows at 31.49% a year. Singapore, Japan, South Korea and India have set blending targets, and Neste's Singapore refinery serves both local and export demand. The region has large volumes of used cooking oil and palm residues, which supports HEFA output, while airlines with long-haul fleets to Europe buy SAF to meet obligations at EU airports. Targets stay smaller than Europe's, so the region adds volume gradually through 2035.

Latin America and the Middle East & Africa act as feedstock-rich exporters

Latin America held 1.6% of 2025 value and is the fastest-growing region at 35.01% a year, driven by Brazil's planned blending mandate and its ethanol base. The Middle East & Africa held 2.1% and grows at 27.49% a year. Gulf hubs supply long-haul fleets, and Africa's reliance on Persian Gulf jet fuel before 2026 raised interest in local supply.

Plant start-ups, a wider mandate area and a U.S. expansion

Feedstock diversity, green hydrogen and certified tracing

• HEFA and co-processing remain central, as hydrotreating waste oils is the workhorse and co-processing in existing units adds renewable jet with little new capital.
• Alcohol-to-jet converts ethanol and isobutanol into jet fuel, tapping U.S. and Brazilian crops and residues and escaping the limits of waste-oil supply.
• Power-to-liquid combines green hydrogen with captured carbon dioxide to produce e-SAF, which the EU requires from 2030 and at 5% by 2035.
• Certification and tracing through ASTM D7566 blend limits, RSB certification and feedstock audits decide which fuel counts toward mandates and tax credits.

Renewable diesel producers, refiners and SAF developers

Supply sits with three groups, starting with renewable diesel producers that own the largest HEFA plants. Neste runs sites in Finland, the Netherlands and Singapore, Diamond Green Diesel, the Valero and Darling Ingredients venture, operates on the U.S. Gulf Coast, and Montana Renewables, part of Calumet, is a leading North American producer. Oil majors such as Enilive, TotalEnergies and Shell convert refineries, co-process and use their airport distribution, blending terminals and long airline supply contracts. Developers of newer pathways, led by LanzaJet and Gevo, license technology and build first plants with airline offtakes. Credence Research estimates that the 5 largest producers supply well over half of 2025 value, because HEFA plants are large and few. Concentration falls as alcohol-to-jet and e-SAF developers enter, but owners of feedstock collection networks keep an edge.

Companies profiled and their roles

SAF is a policy-made market that grows in steps

Credence Research's view is that SAF is a policy-made market that will grow in steps set by law, not by airline pledges or oil prices. HEFA keeps the largest share, but ethanol-to-jet and e-SAF add the most new revenue after 2030 as waste-oil supply tightens and synthetic quotas apply. Producers with secure feedstock, airport distribution and certified supply chains are best positioned. The main risk is that plants slip and fees push airlines to resist. Buyers and investors should watch e-SAF investment decisions, 45Z rules after 2029 and Brazil's mandate.

How Credence Research valued SAF uplift and mandate demand

The report uses 2025 as the base year and forecasts to 2035, with CAGR calculated over 2025–2035. Market values come from Credence Research's market model, which multiplies published SAF output estimates by average delivered prices and builds the forecast from blending shares written into law; segment and regional splits are Credence Research estimates. Supporting evidence comes from airline association data, EU regulation, U.S. tax guidance and company announcements, although opaque offtake prices limit precision.

Synthetic quotas and new feedstocks decide the pace

Through 2035, SAF demand will rise in steps as EU, U.K. and Asian quotas tighten and synthetic sub-shares apply from 2030. HEFA will remain the core route, but ethanol-to-jet, co-processing and e-SAF will carry a growing part of new supply as waste oils run short. Europe will remain the largest buyer, while North America and Brazil expand as producers and exporters. The pace will depend on how quickly first-of-a-kind plants reach design output, the cost of green hydrogen and whether U.S. credits extend past 2029.
