As of January 1, 2026, Switzerland officially adopted the ReFuelEU Aviation regulation, marking a decisive step in the decarbonization of air transport in Europe. This measure makes Zurich and Geneva airports key hubs for the aviation energy transition.

The new regulatory framework requires aviation fuel suppliers to guarantee a minimum blend of 2% Sustainable Aviation Fuel (SAF), a percentage that will progressively increase to 70% by 2050. This clear, long-term trajectory sends a direct signal to the market: the demand for SAF will be structural, growing, and supported by regulation.

Furthermore, airlines will be required to comply with the 90% fuel surcharge rule, a measure designed to prevent the unnecessary transport of additional fuel between airports. This practice, besides being inefficient, generates avoidable emissions; its elimination directly contributes to reducing fuel consumption and CO₂ emissions.

To facilitate the transition, the Swiss Federal Office of Civil Aviation (FOCA) has published a technical guide to support airlines, operators, and fuel suppliers in implementing the regulation. This regulatory support reduces operational risks and accelerates the adoption of sustainable solutions.

From a strategic and investment perspective, the adoption of ReFuelEU in Switzerland strengthens the predictability of the Sustainable Aviation Fuel (SAF) market in Europe. Clear mandates, defined timelines, and institutional support make SAF a central component of the future of aviation, aligning climate objectives with long-term growth opportunities.
