eSAF Mandate
Regulation
The most contested element of European aviation’s decarbonisation framework is not the SAF mandate itself — it is the eSAF sub-mandate, which requires a specific proportion of Power-to-Liquid synthetic fuel rather than biofuel-derived SAF. In recent weeks, airline industry pressure to delay this requirement has intensified. Here is why — and why the sub-mandate should nonetheless be maintained.

What the Airlines Are Saying
Airlines for Europe (A4E) said at its annual summit in Brussels that the 2030 e-SAF sub-mandate must be postponed until e-SAF is sufficiently available and affordable. EasyJet CEO Kenton Jarvis stated: “The reality is, it won’t be there, and you can see it won’t be there. You would have to have multiple plants that had reached an investment decision, they need to be built, then production needs to be scaled up, and then they need to get distribution.”
⚠️ The airlines’ concern is legitimate: The lead time from Final Investment Decision to operational production for a large-scale PtL facility is approximately 3–4 years. For the 2030 sub-mandate to be met, investment decisions need to be made essentially now — in 2026. The current pipeline of approved PtL projects is insufficient to meet the mandate volume.

Why the Sub-Mandate Still Matters
The airlines’ argument contains a structural paradox: the sub-mandate exists precisely to create the investment signal that triggers the construction of the plants they say are missing. Removing or delaying the mandate removes the demand certainty that project developers and their financiers need. Even critics of climate policy acknowledge the strategic logic: “Even people that would deny there is man-made climate change would agree we need to invest in SAF and local fuel production.”
✅ The EU’s pragmatic response: Rather than weakening the mandate, the EU has added a financial incentive layer. Under the new support scheme, the EU will provide up to €6 per litre for e-fuels — enough to fund an estimated 216 million litres of synthetic fuel. This subsidy, combined with the regulatory certainty of the mandate itself, creates the investment environment that PtL projects require.
The Projects That Could Deliver by 2030
LanzaTech FLITE (Ghent, Belgium) — confirmed May 2026, €500M, 79,000 t/year eSAF capacity — is the most advanced large-scale project. Boeing and Norsk e-Fuel have broadened their collaboration on eSAF supply and production. Neste reached 1.5 million tonnes/year biofuel SAF capacity in 2025 — but biofuel SAF does not count toward the PtL sub-mandate, making the challenge for pure eSAF considerably steeper.
📌 The Bottom Line
The sub-mandate debate will define European aviation policy through 2027–2028. Its outcome will either accelerate or delay the commercial scale-up of Power-to-Liquid synthetic fuels. The EU has chosen to maintain the mandate and add financial support. Whether the industry can respond with the required investment decisions in 2026 is the central question.
