CORSIA Eligible Fuels

Latest updates

28 November 2022 ICAO Council approves CORSIA Sustainability Criteria for Lower Carbon Aviation Fuels

12 November 2021 ICAO Council approves CORSIA Sustainability Criteria for sustainable aviation fuels

3 June 2022 - ICAO Council approves amendments to three ICAO documents related to CORSIA eligible fuels


CORSIA allows aircraft operators to reduce its offsetting requirements through the use of CORSIA eligible fuels, which include CORSIA sustainable aviation fuels and CORSIA lower carbon aviation fuels. 

The ICAO CORSIA Implementation Element "CORSIA eligible fuels" is reflected in five ICAO documents referenced in Annex 16, Volume IV. They are available for download below.

 *Sustainability Certification Schemes interested in being evaluated should follow the application process described here.

**The "Guidance to Sustainability Certification Schemes (SCS) for application of CORSIA Sustainability Criteria, Themes 3 to 7, for CORSIA Sustainable Aviation Fuel produced on or after 1 January 2024" provides guidance to SCSs to support globally uniform application, including potentially applicable parameters.

***The CORSIA Supporting Document “CORSIA Eligible Fuels - Life Cycle Assessment Methodology” provides technical information and describes ICAO processes to manage and maintain the ICAO document “CORSIA Default Life Cycle Emissions Values for CORSIA Eligible Fuels”, including the process to add new default values to this ICAO document.


The CORSIA FAQs includes a section on CORSIA eligible fuels (see questions 4.11 to 4.21).

Sustainability Certification

CORSIA eligible fuels shall come from fuel producers that are certified by a Sustainability Certification Scheme (SCS) approved by the ICAO Council to perform this certification (more information on this approval process is available here).

The following flowcharts illustrate the relation between the various entities involved with the sustainability certification of CORSIA Eligible Fuels (click to enlarge).


Definitions (reference: Annex 16, Volume IV )

CORSIA eligible fuel. A CORSIA sustainable aviation fuel or a CORSIA lower carbon aviation fuel, which an operator may use to reduce their offsetting requirements. 
CORSIA lower carbon aviation fuel. A fossil-based aviation fuel that meets the CORSIA Sustainability Criteria under this Volume. 
CORSIA  sustainable  aviation  fuel.  A  renewable  or  waste-derived  aviation  fuel  that  meets  the  CORSIA  Sustainability Criteria under this Volume.
