Page ContentLatest news12 November 2021 ICAO Council approves CORSIA Sustainability Criteria for sustainable aviation 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.CORSIA Eligibility Framework and Requirements for Sustainability Certification SchemesFirst Edition, November 2019CORSIA Approved Sustainability Certification Schemes*First Edition, November 2020CORSIA Sustainability Criteria for CORSIA Eligible Fuels**Second Edition, November 2021CORSIA Default Life Cycle Emissions Values for CORSIA Eligible Fuels***Third Edition, November 2021CORSIA Methodology for Calculating Actual Life Cycle Emissions ValuesSecond Edition, March 2021 *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 following chart illustrates the relation between these documents and the Annex 16 Vol. IV references.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.
