Sustainable Aviation Fuel Mandate Faces Its First Real Test

Kristofer Harr
Legislative Analyst, Economic and Monetary Policy

Toulouse: Europe’s airlines have spent a year under a binding green-fuel rule, and the first hard evidence on whether the policy works has now landed.

The ReFuelEU Aviation regulation forces fuel suppliers at Union airports to blend a rising share of sustainable aviation fuel into ordinary jet kerosene. The mandate opened at 2 percent this year, climbs to 6 percent in 2030 and reaches 70 percent by 2050, with a dedicated sub-target that pushes synthetic e-fuels from a fraction of a percent in 2030 toward 35 percent at mid-century.

The European Union Aviation Safety Agency has published its first annual report on how the rule is landing, and the early numbers cut two ways. In 2024, before the quota bit, sustainable aviation fuel made up just 0.6 percent of the jet fuel supplied to Union airports, all of it delivered voluntarily. Yet operational production capacity across the bloc already stands at 1.4 million tonnes, enough to clear both the 2025 floor and the tougher 2030 threshold.

That gap between capacity and uptake defines the challenge. The fuel exists, but it costs far more than fossil kerosene, and airlines resist paying the premium while passengers hunt for the cheapest seat. The mandate exists precisely to force the market past that standoff by guaranteeing demand no carrier can dodge.

Synthetic e-fuels worry regulators most. These fuels, made from green hydrogen and captured carbon, offer the deepest emissions cuts but barely exist at commercial scale. The agency’s findings point to an urgent need for action on e-fuels, taxation and relentless air-traffic growth, warning that rising passenger numbers could swamp the gains the aviation fuel rules deliver.

Airlines press a competitiveness argument. Carriers that refuel outside the Union escape the blending cost, and operators fear that long-haul rivals will simply tanker in cheaper fuel from third-country hubs. Without safeguards, they warn, the rule could shift emissions and business rather than cut either.

Environmental groups answer that the mandate at last converts pledges into obligations. Voluntary targets delivered almost nothing for years, they note, and only a binding quota has moved suppliers to build capacity at all.

The next reports will decide the argument. If suppliers convert their 1.4 million tonnes of capacity into fuel that actually reaches wings, the policy proves that regulation can drag a stubborn sector toward its climate goals. If the premium and the e-fuel shortfall persist, Europe will confront how much harder aviation is to clean than road transport.
