CORSIA Eligible Fuels

Latest updates

16 June 2023 - ICAO Council approves the expansion of the SCS approvals after the CORSIA pilot phase

14 June 2023 - First sustainable aviation fuel batches certified under CORSIA 

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

Related Standards are defined in Annex 16, Volume IV sections listed below:

2.2.4  Monitoring of CORSIA eligible fuels claims

2.3.3  Reporting of CORSIA eligible fuels

2.4.3  Verification of CORSIA eligible fuels 

3.3    Emissions reductions from the use of CORSIA eligible fuels  

These sections include references to 5 ICAO documents that are essential to the implementation of the CORSIA. These ICAO documents are available below, and may only be amended by the ICAO Council.

 *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 4 to 8, 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.
