About SAF.fyi
Bringing transparency to the sustainable aviation fuel market
Our Mission
SAF.fyi is dedicated to bringing transparency and accountability to the sustainable aviation fuel (SAF) market. As the aviation industry works toward net-zero emissions, SAF represents one of the most promising pathways to decarbonization. Our platform tracks contracts, deliveries, and retirements to help stakeholders understand the true state of SAF adoption globally.
What is Sustainable Aviation Fuel?
Sustainable Aviation Fuel (SAF) is a biofuel that can be used to power aircraft with significantly reduced lifecycle carbon emissions compared to conventional jet fuel. SAF can be made from various sustainable feedstocks including:
- Used cooking oils and animal fats (HEFA pathway)
- Agricultural and forestry waste (Fischer-Tropsch pathway)
- Alcohol from sustainable sources (Alcohol-to-Jet pathway)
- Green hydrogen and captured CO2 (Power-to-Liquid / e-SAF)
What We Track
Contracts
Purchase agreements between airlines, corporates, and SAF producers
Deliveries
Actual SAF volumes delivered against contracted commitments
Retirements
Certificate retirements and environmental attribute claims
Data Sources
Our data is compiled from multiple sources to ensure comprehensive coverage:
- Official press releases from airlines and SAF producers
- Registry data from RSB, ISCC, and other certification bodies
- Regulatory filings and sustainability reports
- Industry announcements and news sources
- Community submissions (verified before publication)
SAF Production Pathways
HEFA
Hydroprocessed Esters and Fatty Acids - The most common pathway, using waste oils and fats
Fischer-Tropsch (FT)
Converts solid biomass or municipal waste into liquid fuels through gasification
Alcohol-to-Jet (ATJ)
Converts ethanol or other alcohols into jet fuel through chemical processes
Power-to-Liquid (e-SAF)
Uses renewable electricity to produce hydrogen, combined with captured CO2
