Start with the distinction between a physical fuel delivery and an environmental attribute. Then examine the evidence behind the claim.
SAF enters the aviation fuel network through a physical supply chain. Procurement needs to address location, fuel specification, availability, pricing and traceable documentation.
Any lifecycle benefit depends on the specific fuel pathway and supporting evidence. A SAF purchase does not mean zero emissions at the aircraft.
A buyer can obtain attributed environmental benefits associated with SAF supplied elsewhere. This does not establish that the buyer’s own aircraft uplifted that fuel.
Review registry rules, allocation, retirement, additionality where relevant, and the permitted reporting treatment. Guard against duplicate claims.

A percentage reduction for neat SAF is different from a reduction across a blended annual fuel portfolio.
Test your own assumptions ↗A 10% SAF share and assumed 70% lifecycle improvement for that share imply a 7% fuel-portfolio reduction in a simplified equal-energy model.
This is a screening calculation. It is not a certified emissions inventory or a compliance calculation.Physical product, certificate or other attributed benefit: define exactly what changes hands.
