Sustainable aviation fuel 2026: the mandate decade, CORSIA Phase 2, and the HEFA bottleneck
Production sits at roughly 1 million tonnes against a 360 million tonne jet fuel market, yet ReFuelEU, the UK SAF Mandate, US Section 45Z, and CORSIA Phase 2 have anchored a five year compliance window that pulls SAF from voluntary corporate procurement into binding national obligation. Refiners, airlines, OEMs, and policymakers must now triage between mature HEFA, fast scaling alcohol to jet, and structurally expensive power to liquid.
IATA pegged 2024 SAF production at approximately 1 million tonnes, roughly 0.3 percent of the 360 million tonnes of jet fuel consumed by commercial aviation, with HEFA via used cooking oil and animal fats accounting for around 85 percent of supply. The mandate stack is now binding: ReFuelEU Aviation requires 2 percent SAF blending in EU a...
Sustainable Aviation Fuel in 2026: A Mandate Wall Without a Molecule Cushion
ReFuelEU is live, the UK SAF mandate ratchets, and ICAO CORSIA Phase II turns mandatory in 2027. Global SAF supply remains roughly 0.3 percent of jet fuel demand, and HEFA feedstock is already binding.
Aviation entered 2026 facing the first compliance year of EU ReFuelEU obligations, a 2 percent SAF blend floor at all EU airports, and a parallel UK mandate climbing toward 10 percent by 2030. ICAO CORSIA Phase II becomes mandatory in January 2027 for all member states whose carriers fly international routes. Global SAF production is on t...
