Strategic book-and-claim can de-risk e-kerosene in the Sustainable Transport Investment Plan, industry tells Commission
Letter | October 2025
Summary
The Sustainable Transport Investment Plan (STIP), set to be announced in late 2025, is expected to be a major pillar of the Clean Industrial Deal.
E-kerosene, or synthetic aviation fuel, offers a major opportunity to advance Europe’s clean industrialisation goals: it is the most sustainable and most scalable alternative drop-in aviation fuel, and Europe is uniquely poised to capture a global competitive advantage in this burgeoning market.
However, despite the enormity of this opportunity, e-kerosene producers are struggling to achieve final investment decision and scale production.
For this reason, the SASHA Coalition wrote a letter to European Commissioners and the Danish Presidency of the Council of the EU recommending that a well-regulated book-and-claim system for e-kerosene is introduced in the upcoming STIP.
What does the letter say?
The letter called for a book-and-claim system that drives Europe’s Clean Industrial Deal goals of energy security, and clean and competitive industry by following adhering to three criteria, that it:
Operates just for e-kerosene, to give targeted support to the most sustainable but least mature alternative drop-in aviation fuel.
Operates just in the EEA, to concentrate competitiveness gains to European producers.
Is timebound with an end-date, to ensure the physical infrastructure is developed to distribute e-kerosene across the EU in the long run.
