The European Union Aviation Safety Agency (EASA) has published its 2026 ReFuelEU Aviation Annual Technical Report, covering the first full year of mandatory ReFuelEU Aviation compliance. Fuel suppliers reported 39.3 million tonnes of aviation fuel supplied at Union airports in 2025, including 1.1 million tonnes of sustainable aviation fuel (SAF), equal to 2.79% and above the 2% mandate. SAF supply increased nearly sixfold from 193,000 tonnes in 2024 and reached 121 Union airports across all 27 EU Member States, or 79% of Union airports. EASA calculates that SAF use delivered 3.77 million tonnes of CO₂e emissions savings, with a weighted average reduction of 89% compared with conventional jet fuel. EASA says projected EU SAF production capacity remains on track to meet the 2030 minimum share, excluding synthetic aviation fuels, while the synthetic aviation fuel market remains at an early stage of development. Most SAF supplied was produced in the EU, but 85% of feedstocks originated outside the EU, with used cooking oil accounting for 80% of SAF supplied.
