Green Kerosene Hits the Tarmac as EU Aviation Rules Face First Annual Reality Check

The European Union Aviation Safety Agency (EASA) has released its first annual report tracking the implementation of the ReFuelEU Aviation Regulation. The document delivers the EU's first comprehensive snapshot of sustainable aviation fuel (SAF) availability and supply across member state airports during 2025, which marked the inaugural year of legally binding compliance mandates. According to EASA, the results demonstrate solid initial progress in expanding green fuel distribution, offering the first empirical evidence that the bloc's regulatory framework is translating into physical fuel in aircraft tanks.

For everyday air passengers, sustainable aviation fuel represents the primary mechanism for reducing the climate impact of flying without grounding fleets. Derived from waste fats, agricultural residues, or synthetic hydrogen, SAF can cut lifecycle carbon emissions by up to 80 percent compared to conventional jet kerosene. However, because alternative fuels remain vastly more expensive to produce, the transition inevitably carries economic consequences. EASA's tracking matters because it confirms whether alternative fuels are actually reaching airport hydrants in required volumes, laying the groundwork for a cleaner aviation sector while quietly reshaping the underlying economics of air travel.

The ReFuelEU Aviation Regulation is a classic example of EU legislative engineering designed to solve a market deadlock. Historically, fuel refiners refused to invest in expensive SAF production without guaranteed buyers, while airlines refused to sign purchase agreements without assured supply. European lawmakers resolved the standoff by simply ordering the market into existence, imposing mandatory minimum SAF blending quotas at EU airports starting in 2025. EASA acts as the technical enforcer, auditing compliance across hundreds of hubs and monitoring against 'tankering'—the practice where airlines overfuel at non-EU airports to dodge higher local fuel costs and environmental standards.

With the first compliance milestone cleared, the regulatory obligations under ReFuelEU Aviation will ratchet up automatically in the coming years. Blending mandates are structured to scale upward progressively, targeting a 6 percent SAF blend by 2030 and reaching 70 percent by 2050. EASA will publish annual monitoring reports to ensure refining capacity keeps pace with the law, giving national aviation authorities the data needed to issue penalties to non-compliant fuel suppliers and airlines.
