Sustainable Aviation Fuel Hits $2,640 a Ton: Why SAF Demand Is Outrunning Supply in 2026
Sustainable aviation fuel is scaling fast in percentage terms while still representing a tiny fraction of what airlines actually burn. The global SAF market is projected to grow from $4.86 billion in 2026 to $31.45 billion by 2031, a 45.3% CAGR, one of the fastest-growing segments in aviation. Yet global SAF production is expected to reach only about 2.4 million tonnes in 2026, roughly 0.8% of total annual jet fuel consumption, up from 0.6% in 2025, a growth rate that's actually decelerating even as market value estimates climb.
Prices Are Spiking as Mandates Bite
In early March 2026, the spot price for SAF in Northwest Europe hit $2,640 per metric ton, a 29% jump in a single month, while FOB Singapore jet fuel reached an all-time high of $231.42 per barrel, more than 33% above the previous record set during the 2022 energy crisis. SAF currently costs several times more than conventional jet fuel, and in some mandated markets the premium reaches five times the price of fossil-based fuel, reflecting more expensive feedstocks, immature production technology, and thin physical and market infrastructure.
Mandates Are Multiplying Across Regions
The UK's SAF Mandate, in force since January 2025, starts at 2% blending and escalates to 22% by 2040, with a separate obligation requiring 0.2% of total jet fuel supply from power-to-liquid sources by 2028
Singapore requires all departing flights to incorporate SAF starting in 2026, beginning at 1% and escalating to 3-5% by 2030
India has set a 1% indicative blending target for 2027 and 2% for 2028, initially covering international flights
The US SAF Grand Challenge targets at least 3 billion gallons of domestic SAF production capacity annually by 2030, scaling to 35 billion gallons by 2050
Feedstock, Not Technology, Is the Real Constraint
Industry analysts increasingly agree that SAF scale-up isn't constrained by technology alone but by competition for low-carbon feedstocks, pushing producers toward incremental capacity expansions and flexible production strategies in 2026 rather than large, single-bet investments. Neste is expanding global SAF production capability from 1.5 million tons to 2.2 million tons annually by 2027 and extended its partnership with World Fuel Services to widen SAF distribution across more than 100 European airports.
Geopolitics Is Reinforcing the Investment Case
Recent regional conflicts have exposed the vulnerability of conventional fuel supply chains, strengthening the case for domestically produced SAF as a strategic hedge rather than purely an environmental commitment. That combination of record fuel prices and accelerating mandates is converging to make SAF production capacity one of the more compelling capital allocation decisions in the broader energy transition right now.
What It Means for the Market
SAF's core tension in 2026 is that demand created by policy mandates is genuinely outrunning the feedstock and production capacity needed to supply it, driving prices to record levels even as percentage-of-total-fuel figures remain small. Producers who can lock in low-carbon feedstock supply and scale incrementally, following Neste's model, are best positioned to capture value as mandates keep tightening across Europe, Asia-Pacific, and North America through the rest of the decade.
