ReFuelEU Aviation Annual Technical Report 2025 (EASA)

The context: who needs to do what?

• Under the ReFuelEU Aviation Regulation (EU 2023/2405):
  Aviation fuel suppliers must start blending a minimum share of SAF into jet fuel sold at Union airports – beginning at 2% in 2025 and rising steadily to 70% by 2050.
• Aircraft operators must uplift at least 90% of their required fuel at Union airports (to prevent tankering) and report their SAF purchases and claims under schemes like the EU ETS.
• Union airports management bodies must facilitate access to SAF.

2024 served as a “dry run” before these obligations kick in fully.

The highs

• 17 EU countries now have active or planned SAF production sites (up from 12 in 2023).
• SAF delivered in 2024 achieved 91% lower emissions than fossil jet fuel, avoiding 714,000 tonnes of CO₂.
• Reporting and data systems are improving – a strong start for compliance tracking.

The lows

• Only 0.6% of jet fuel supplied in 2024 was SAF – far below the 2025 target.
  Most SAF came from cooking oil (81%) and animal fats (17%) showing limited feedstock diversity.
• No synthetic fuel projects have reached final investment decision yet – a risk for future targets.

What it means

• The EU aviation sector is getting serious about decarbonisation – but the learning curve is steep.
• From 2025 onward, airlines and suppliers will face real compliance, reporting, and verification requirements.

That’s where Vertis Environmental Finance can help. We support aircraft operators to:

• Understand and meet their ReFuelEU and EU ETS obligations
• Make credible SAF claims and avoid double counting
• Integrate carbon and SAF strategies for compliance and reputation
