Sustainable aviation fuel stocks are entering their most important commercial phase yet in 2026 — a year when production capacity is expanding, regulatory mandates are tightening, and airlines are signing long-term offtake agreements that signal genuine industrial commitment rather than greenwashing. For investors, the opportunity is real. So is the complexity.
Sustainable aviation fuel (SAF) is produced from non-petroleum feedstocks — agricultural and food waste, used cooking oil, agricultural residues, and in emerging pathways, captured CO₂ combined with green hydrogen. It can reduce lifecycle carbon emissions by up to 80% compared to conventional jet fuel, and crucially, it works in existing aircraft without modification. There are no electric planes for long-haul routes any time soon. SAF is aviation’s primary near-term decarbonization pathway.
The Market in 2026
The global SAF market is growing at extraordinary speed. The market was valued at $3.72 billion in 2025 and is projected to reach $5.75 billion in 2026 — a 54.5% year-over-year growth rate. US production capacity has been expanding rapidly, with US Other Biofuels production (the category that captures SAF) more than doubling between 2024 and 2025, according to the US Energy Information Administration. Further 20% growth is forecast for 2026.

Meeting likely 2030 demand requires an additional 5.8 million tonnes of annual production capacity to reach final investment decision by 2026, according to the World Economic Forum. That urgency is concentrating minds — and capital — on near-term project execution.
Recent Market Developments
Activity in the first quarter of 2026 illustrates the market’s growing commercial maturity. Infinium’s Project Atlas — an electrofuel (eSAF) project targeting 95% carbon intensity reduction versus fossil jet fuel — was selected by the Sustainable Aviation Buyers Alliance (SABA) for a next-generation SAF procurement contract, with American Airlines as the physical fuel recipient. This book-and-claim structure allows corporate buyers to claim the emissions reduction even when SAF doesn’t flow directly into the aircraft their employees fly — a critical mechanism for unlocking corporate demand at scale.
SAF pricing remains well above conventional jet fuel and is expected to remain so through 2026. This means airlines and corporate buyers are absorbing a cost premium as a compliance and reputational investment rather than a pure economics decision. For SAF producers, this creates a window to scale before costs normalize — provided offtake agreements are in place.
The Feedstock Challenge
The current SAF market is dominated by HEFA (Hydrotreated Esters and Fatty Acids) — produced from used cooking oil, soybean oil, and similar lipid feedstocks. HEFA accounts for over 95% of current SAF production. The challenge is feedstock availability: sustainable lipid supplies are finite, and as SAF mandates expand globally, competition for feedstocks will intensify.
Next-generation pathways — alcohol-to-jet (ATJ), Fischer-Tropsch from municipal solid waste, and power-to-liquid eSAF — have higher capital costs but much larger feedstock addressable markets. Most near-term investment opportunities are in HEFA, while the most interesting long-term bets are in next-gen pathways. Understand which you’re buying before investing.
How to Invest
Pure-play publicly traded SAF producers remain scarce — the sector is still largely populated by private startups. The primary listed routes are:
Neste (NESTE.HE) — the world’s largest renewable fuel producer and a dominant SAF supplier, with a significant international customer base and established HEFA production infrastructure. This is the most direct large-cap listed exposure to the SAF market.
Phillips 66 (NYSE: PSX) — has completed a 10,000 barrel per day SAF conversion project in Rodeo, California, giving it meaningful SAF production capacity within a broader refining portfolio.
Renewable energy and biofuel ETFs with SAF producer allocations offer diversified exposure. The US Energy Information Administration tracks SAF production capacity growth and provides useful data context for evaluating producer positioning.
Watch for upcoming listings from companies currently in late-stage VC or pre-IPO stages. As the SPAC market has cooled, traditional IPO routes are more likely for the next wave of SAF pure-plays.
Bottom Line
SAF is growing faster than almost any other clean energy segment — and unlike many climate technologies, it has clear and immediate demand from a regulated industry with no short-term alternative. The investment case is strong but requires careful navigation of feedstock risk, policy dependency, and the maturity of each production pathway. The companies building reliable, long-term contracted SAF supply at competitive cost are where the durable value lies.
