Sustainable Aviation Fuel (SAF)
A drop-in aviation turbine fuel produced via ASTM D7566-approved pathways. Once blended and certified within approved limits, it is handled exactly as Jet A-1 in existing aircraft and airport infrastructure.
SAF
Key technical properties
ASTM D7566 governs the neat SAF component; the finished blend meets ASTM D1655 / DEF STAN 91-091.
| Property | SAF limit |
|---|---|
| Neat SAF specification | ASTM D7566 (approved pathways) |
| Finished blend specification | ASTM D1655 / DEF STAN 91-091 |
| Typical pathways | HEFA, FT-SPK, ATJ, SIP, HC-HEFA |
| Max blend ratio (pathway-dependent) | Up to 50% vol (HEFA/FT typical) |
| Drop-in compatibility | Yes, existing engines & infrastructure |
| Flash / freeze / density | Per Jet A-1 after blending |
| GHG reduction potential | Up to ~80% vs fossil Jet A-1 |
| Sustainability certification | ISCC / RSB (pathway & batch) |
| Compliance support | CORSIA · ReFuelEU · chain of custody |
| Supply options | Physical blend · Book & claim |

Frequently asked questions
Which SAF pathways are approved?
ASTM D7566 approves several pathways including HEFA, FT-SPK, ATJ, SIP and HC-HEFA, each with pathway-specific blend limits.
What is the maximum SAF blend ratio?
Typically up to 50% by volume for HEFA and FT-SPK pathways; some pathways are capped lower per ASTM D7566 annexes.
Does SAF require engine modifications?
No. Certified SAF blends are drop-in fuels, no engine, airframe or fuel infrastructure changes are required.
