Sustainable aviation fuels (SAF) are defined as renewable or waste-derived aviation fuels that meets sustainability criteria1. Technical analysis done at ICAO shows that SAF has the greatest potential to reduce CO2 emissions from International Aviation.
ICAO is working to facilitate SAF development and deployment through four main streams:
1) Globally-accepted environmental Standards for SAF
CORSIA includes specific methodologies that allow aircraft operators to reduce its offsetting requirements through the use of SAF and Lower Carbon Aviation Fuels (LCAF), including globally-accepted sustainability criteria and life cycle methodologies. These are being developed by CAEP, through its Fuels Task Group (FTG).
Specific details on how SAF is considered under CORSIA are provided in the ICAO Environmental Report 2019, Chapter 6 - An Overview of CORSIA Eligible Fuels (CEF). Related documents are provided in the CORSIA eligible fuels website.
2) SAF goals, policies, and measures
SAF Trends - The possible contribution of SAF to the ICAO environmental goals is also being assessed by CAEP as part of the ICAO Global Environmental Trends.
ACT-SAF - ICAO Assistance, Capacity-building and Training for Sustainable Aviation Fuels
SAF rules of thumb - what does it take to produce SAF?
"Rules of Thumb" developed by CAEP experts can be utilized to make order of magnitude estimations related to SAF costs, investment needs and production potential.
SAF technical references
Several other references on SAF are being compiled by ICAO and provided to the general public. More information can be found in the "other resouces" webpage.
