SAF Flexibility Mechanism

Let’s talk about the SAF Flexibility Mechanism in the EU.
✅ Main Documents:
- ReFuelEU Aviation
- Report from the European Commission about SAF flexibility mechanism
- Study supporting the impact assessment of the ReFuelEU Aviation initiative
☑️ What is the SAF Flexibility Mechanism?
📌 the SAF flexibility mechanism allows an aviation fuel supplier to supply the minimum shares of SAF as a weighted average over all the aviation fuel it supplied across all EU airports for each reporting period.
📌 the SAF flexibility mechanism is intended to give the SAF industry sufficient time to scale up its production and supply capacities.
📌 this means that aviation fuel suppliers may supply aviation fuels containing higher shares of SAF in certain EU airports to compensate for aviation fuels containing zero or lower shares of SAF in other EU airports.
📅 The SAF flexibility mechanism applies from 1 January 2025 until 31 December 2034.
✅ Some key conclusions from SAF flexibility mechanism report:
📌 Compliance with targets:
- Aviation fuel suppliers can claim the supply of SAF for the purposes of complying with their ReFuelEU Aviation obligations and contributing to the national RED targets.
- EU law does not prevent a batch of SAF to be certified under more than one certification scheme (e.g. RED, CORSIA certified fuels).
- Aircraft operators can claim the use of a given quantity of SAF under one GHG reduction scheme, including the EU ETS and ICAO’s CORSIA.
📌 Virtual trading of SAF sustainability certificates
- there is no unified industry-wide position neither on the design or the necessity of implementing such an accounting mechanism system for the purposes of complying with current blended SAF obligations and of claiming their use under other pieces of EU law, such as the EU ETS that does not allow aircraft operators to claim the use of blended SAF without physically delivery.
- virtual trading of SAF sustainability certificates may bring new dynamics to the market on the demand side, but it is not clear whether this would have any real impact on the production side at this early stage.
📌 Availability of blended SAF at EU airports
- the risk of a significant geographic concentration of blended SAF in few EU airports is limited.
- most aviation fuel suppliers operate only within the borders of their respective Member State, so the possibility of significant geographic concentration is already largely limited to national markets.
- many EU airport managing bodies have clearly communicated their intention to make blended SAF available in the coming years on their premises.
- projects for new SAF capacities are appearing in various locations across the EU.
