SAF and the Big Lebowski Problem

A man stands in the mansion of a zillionaire explaining how his rug has been unmistakably peed on — and how the zillionaire is responsible.

“Well, sir, it’s this rug I have. It really tied the room together. They were looking for you… these two guys… they tried to— well, they tried to pee on your rug.”

Across the room, the billionaire in a motorized wheelchair adjusts his cufflinks.

“Did I urinate on your rug?”

“Well… no.”

“Let me understand this. Every time a rug is micturated upon in this fair city, I am to compensate the person?”

If you know the film, you know the scene from The Big Lebowski. And it abides, man — it absolutely abides — when it comes to explaining where we are with Sustainable Aviation Fuel.

You’ve heard for months — perhaps years — as the screaming pace of SAF announcements slowed to a trickle of financial closes and construction starts — that SAF has a Big Problem. The diagnosis depends on which Dude is at the podium: chemistry. feedstocks. scale. policy. offtake.

But let me say it here first, SAF doesn’t have a Big Problem. It has a Big Lebowski problem. 

The obstacle isn’t the green premium. It isn’t scale, or feedstock, or regulation. It’s allocation. It’s who pays for the rug. Conventional jet fuel hovers around $90 per barrel. SAF still carries a 2x–4x premium. That spread represents roughly $4.5 billion in incremental cost this year for airlines operating on thin margins. Everyone agrees the room looks better with the rug. No one wants to buy it.  What should be a straightforward allocation debate has instead become a Mexican standoff. But February 2026 suggests something important: The standoff is beginning to thaw.

The Passenger Picks Up a Corner

Singapore has moved first to break the deadlock.

The Civil Aviation Authority of Singapore is implementing a SAF levy beginning in April, adding roughly S$6.40 to a long-haul economy ticket. It’s modest. It doesn’t erase the premium. But it does something critical: it aligns benefit with contribution. The public benefits from cleaner skies. The public contributes.

More interesting still is the corporate coalition forming around the Singapore Sustainable Aviation Fuel Company (SAFCo). Nine major players—including Google, Temasek, DBS Bank, and Boston Consulting Group—are aggregating demand through a centralized procurement trial. Individually, no airline wants to “mark it zero” on its margin sheet. Collectively, corporates can create a bankable demand signal. This is no longer symbolic. It is shared burden.

Japan Builds the Full Stack

While Singapore adjusts the demand side, Japan is engineering the supply chain with characteristic precision.

Cosmo Oil has partnered with Shimonoseki city to collect used cooking oil from households and restaurants—literally building the supply chain from fryer to wing. A consortium involving Pietro, Revo International, and Ecos is funneling waste oils into SAFFAIRE SKY ENERGY, a joint venture with Cosmo Oil and JGC Holdings. Vertical integration is tightening the chain of custody.

Meanwhile, Mitsubishi Heavy Industries has demonstrated integrated synthetic fuel production using solid oxide electrolysis. Hydrogen and carbon monoxide feed Fischer–Tropsch synthesis, producing SAF, marine fuel, and city gas in a single industrial loop. This is not a pilot program waiting for permission. It’s a full stack being assembled.

India and Indonesia: Scale Arrives

If Japan is the engineer, India and Indonesia are the builders.

Indonesia’s sovereign wealth fund Danantara has launched $7 billion in downstream bioenergy projects. Pertamina’s facility in Central Java currently produces 27 kiloliters per day, targeting 887 kiloliters daily by 2029. In India, Honeywell has signed with TruAlt Bioenergy to deploy ethanol-to-jet technology targeting 80,000 tons annually. Simultaneously, Honeywell is deploying Ecofining technology with SAF One Energy Management and Tata Projects to convert waste fats and oils. Asia is no longer observing Europe. It is pouring concrete.

Europe: Rules and Reality

Europe remains the regulatory heavyweight—and the most anxious bowler in the league.

ReFuelEU mandates are driving demand, but airline executives warn that if competitors outside the EU are not subject to equivalent rules, European carriers face structural disadvantage. It’s not a rejection of climate ambition. It’s a dispute over the scorecard. If one group blends expensive SAF and another refuels elsewhere, markets distort.

Still, steel is rising.

SkyNRG has reached financial close on its 100,000-ton DSL-01 facility in Delfzijl. LanzaTech has committed to its $820 million DRAGON II project at Saltend Chemicals Park in the UK. Neste continues scaling capacity toward 2.2 million tons annually by 2027. Heathrow Airport has assembled an £80 million incentive pool targeting a 5.6% blend rate—above the UK mandate—and says 17% of global SAF supply in 2024 flowed through its terminals. Even in the most rule-bound league, players are investing.

The Americas: Plumbing and Pragmatism

In Brazil, policymakers are preparing to lift the ban on importing used cooking oil to supplement domestic supply, even as they promote ethanol as the long-term feedstock anchor.

Cemvita and Radix are advancing projects converting crude glycerin into low-carbon feedstock—a circular squeeze on waste streams.

In the United States, FedEx has expanded SAF use to DFW and JFK, securing 2 million gallons of neat SAF in partnership with World Fuel Services. And in one of the more elegant signals of market maturation, Kuehne+Nagel and LATAM Cargo executed a 495-ton Valentine’s Day flower shipment under a Book-and-Claim system, reducing emissions while moving commerce. SAF isn’t just about passengers. It’s about global trade.

Emerging Signals

In South Korea, a KRICT-led pilot plant converted landfill gas into SAF at modular scale—100 kg per day in a 100-square-meter footprint.

In Malaysia, FatHopes Energy’s feasibility study underscored a central truth: traceability is becoming the license to operate. Proving that waste oil is truly waste is no longer optional. Even geopolitics bends toward fuel. Adelaide University secured funding to collaborate with China on SAF development. When rivals share notes on aviation fuel, the imperative is clear.

The Dude Abides

The green premium hasn’t vanished. The Big Lebowski problem isn’t solved. But the argument is changing.

Passengers in Singapore are contributing. Corporates are aggregating demand. Airports are subsidizing. Governments are mandating. Producers are deploying capital. No single billionaire has replaced the rug. Instead, multiple parties are lifting a corner. SAF was never purely a chemistry problem. It was always an alignment problem—between burners, beneficiaries, and builders. The room still needs tying together. But for the first time in years, fewer people are pretending it replaces itself. And in markets, as in bowling leagues, once the rules are accepted and the cost is shared—

And so, the Digest abides. Or, Gli Digesterati, or, uh, Los Digesterinos, if you’re not into the whole brevity thing.
