ReFuelEU’s First Year Shows the Mandate Works

What did EASA’s first annual report reveal about the EU’s sustainable aviation fuel market in 2025?

EASA’s annual technical report is important because it examines the first year when ReFuelEU Aviation targets became mandatory. That moves SAF from policy ambition into a market that can be measured. The report offers Europe’s first full picture of supply, use, and compliance under the new rules.

The supplied article excerpt does not provide specific 2025 volumes, prices, or compliance percentages. It only identifies the report as covering 2025 data and says its findings show that the mandate works. Those missing figures would be needed to quantify the market’s performance.

The broader message is that regulation is creating a clearer SAF market signal. Airlines, fuel suppliers, and producers can plan around known demand. The article’s headline also points to the next challenge: Europe must unlock investment, especially for emerging fuels such as e-SAF, if it wants the market to grow beyond initial compliance.

What is ReFuelEU Aviation, and what does its SAF mandate require airlines and fuel suppliers to do?

ReFuelEU Aviation is an EU regulation designed to reduce aviation emissions by requiring sustainable aviation fuel at European airports. It matters because voluntary SAF use has been limited by high costs, scarce supply, and uncertainty about future demand. A legal target gives producers and investors a predictable market.

The regulation places the main blending obligation on aviation fuel suppliers. They must make specified amounts of SAF available at EU airports. Airlines must then use the required fuel and report their consumption. The rules also address “tankering,” where aircraft carry extra fuel from another airport to avoid buying costlier SAF.

The first target began in 2025 at 2% of fuel supplied at covered EU airports. Targets rise over time. This creates pressure for both sides of the market: suppliers must build production and distribution, while airlines must adapt operations and purchase cleaner fuel as availability expands.

How much sustainable aviation fuel was used in Europe in 2025, and how close was this to the mandate’s target?

The key comparison is between actual SAF use and the first ReFuelEU Aviation requirement. For 2025, the EU-wide target was 2% of aviation fuel supplied at covered airports. Reaching that level would show that the new rule translated into real fuel purchases rather than remaining a paper commitment.

However, the supplied article excerpt does not give Europe’s total SAF volume or its measured percentage. It says only that EASA published a report based on 2025 data and that the report provides the first full market picture. Therefore, a precise answer about tonnes used or the exact gap to the target cannot be supported by the available text.

The important implication is still clear. EASA’s data should establish whether suppliers delivered enough SAF and airlines used it as required. Those results can reveal where shortages remain and help determine how quickly Europe needs new production, infrastructure, and investment.

How can a fuel mandate increase the production and use of SAF rather than simply raise airlines’ costs?

A fuel mandate does more than add a cost at the airport. It creates dependable demand. Producers can justify building SAF plants because airlines and suppliers must meet legal requirements. Investors also gain clearer evidence that future customers will exist, reducing one of the biggest risks in a young market.

The mechanism is straightforward. A required SAF share creates purchase commitments across many airlines. Those commitments support new plants, feedstock contracts, fuel terminals, and certification systems. As production grows, manufacturers can spread fixed costs over more fuel, improve technology, and compete for customers. Airlines may also use long-term agreements to stabilize prices and supply.

Costs can rise initially because SAF is usually more expensive than fossil jet fuel. But the mandate can shift the market from small, voluntary purchases to industrial-scale production. ReFuelEU’s first-year report, described as showing that the mandate works, suggests regulation is beginning to perform that market-building role.

What is e-SAF, and why does Europe need new investment to produce more of it?

e-SAF, also called power-to-liquid or synthetic aviation fuel, is made from hydrogen produced with electricity and carbon taken from the air or another qualified source. The hydrogen and carbon are processed into hydrocarbons that can replace conventional jet fuel. It matters because it can reduce lifecycle emissions without requiring entirely new aircraft.

Its key mechanism links clean electricity to aviation fuel. Electrolyzers split water into hydrogen and oxygen. Captured carbon is then combined with hydrogen and converted into liquid fuel. The climate benefit depends on using low-carbon electricity and genuinely sustainable carbon sources. Otherwise, the production process can lose much of its advantage.

Europe needs investment in renewable power, electrolyzers, carbon-capture systems, fuel plants, pipelines, and airports. These projects are expensive and technically complex. ReFuelEU can create demand, but policy support and long-term financing are still needed to move e-SAF from demonstration projects toward commercial volumes.

What other technologies or feedstocks can produce SAF if e-SAF is not yet available at sufficient scale?

e-SAF is not the only route to sustainable aviation fuel. Today’s alternatives include fuels made from used cooking oil, animal fats, agricultural residues, forestry residues, municipal waste, and certain industrial waste gases. Some pathways convert alcohols into jet fuel, while others turn solid waste into synthetic hydrocarbons.

The production mechanism depends on the feedstock. Oils and fats can be processed through hydroprocessed esters and fatty acids, commonly called HEFA. Alcohol-to-jet pathways upgrade ethanol or other alcohols into aviation fuel. Gasification and Fischer-Tropsch processes can convert waste or biomass into a synthetic fuel. Each route has different costs, yields, and emissions.

These options can help meet early mandates while e-SAF expands. But supply is limited, and not every waste or crop-based pathway is automatically sustainable. Europe must check land use, biodiversity, indirect emissions, feedstock availability, and lifecycle carbon savings. A diverse portfolio is safer than relying on one technology.

Why is aviation difficult to decarbonize with batteries or hydrogen alone, and how do alternative fuels reduce its climate impact?

Aviation is difficult to electrify because aircraft must carry energy while keeping weight extremely low. Batteries are much heavier for the energy they store than liquid jet fuel. Hydrogen can be low-carbon, but it needs bulky tanks and very cold storage, and aircraft would require redesigned systems. Long-distance flights make these challenges harder.

Alternative fuels reduce emissions by replacing some fossil-derived jet fuel with lower-carbon molecules. Most SAF is designed as a drop-in fuel, meaning it can be blended with conventional fuel and used in existing aircraft and airport systems. Its lifecycle benefit depends on its feedstock, electricity source, production method, and transport.

This makes SAF a practical near-term tool, especially for long-haul aviation. It does not eliminate aviation’s climate impact, and supply remains limited. Batteries, hydrogen, efficiency improvements, and SAF may therefore serve different routes and aircraft types as technology develops.
