Green Public Procurement

A Catalyst for Scaling Up Synthetic, Sustainable Aviation Fuels (eSAF)

PtX Lab Paper | 11/2025 | Topic: Aviation | 11 Pages

The PtX Lab Paper Green Public Procurement – A Catalyst for Scaling Up Synthetic, Sustainable Aviation Fuels (eSAF) examines how green public procurement (GPP) as a voluntary demand-pull instrument can support the market ramp-up of sustainable and synthetic aviation fuels (SAF/eSAF).

It explains differences from regulatory requirements (ReFuelEU), highlights the role of government buyers – especially the military – as reliable contractual partners, and discusses technical, legal and certification requirements (e.g. RSB, ISCC, ASTM standards).

It proposes a staggered GPP quota (increasing to 50% by 2030), long-term purchase agreements to reduce investment risks, and a rough cost and volume calculation (including ~164kt eSAF by 2030; tender volume ≈ €896 million in the planning phase). Potential opportunities (market security, first-mover funding) are critically weighed against risks (limited government volume, additional costs, bureaucracy).

In summary, the paper deals with practice-oriented policy recommendations for authorities and decision-makers in the field of procurement and energy policy.
