IATA – Sustainable Aviation Fuel (SAF) Accounting & Reporting Methodology

The International Air Transport Association (IATA) has developed a Sustainable Aviation Fuel (SAF) Accounting & Reporting Methodology to help airlines estimate and report emissions reductions from the use of SAF. This methodology includes pre-flight accounting, such as estimating CO2 emissions reduction and the volume of SAF needed to meet decarbonization goals, as well as post-flight accounting, which involves estimating emissions reduction from consumed SAF and associated with aviation service users. It is important to note that this methodology does not replace existing accounting approaches in regulatory frameworks. SAF emissions reduction is calculated on a life cycle basis (well-to-wake) through life cycle assessments comparing SAF to conventional aviation fuel. SAF blends must meet the same specifications as conventional fuel but offer significant environmental benefits due to being made from non-fossil sources. Airlines must ensure there is no double counting or claiming of emissions reduction when reporting across various frameworks.
