IATA releases SAF accounting and reporting methodology

In Switzerland, the International Air Transport Association (IATA) released its methodology for accounting and reporting the emissions reduction associated with the use of SAF by airlines. IATA noted that the publication of the IATA SAF accounting and reporting methodology is a critical step in the preparation of the IATA SAF Registry which is scheduled to launch in April 2025. The IATA SAF Registry is expected to play a key role in creating a functioning global SAF market. “The IATA methodology will provide a consistent approach to accounting for the environmental benefits of SAF purchases, regardless of location. This is an essential component of the soon-to-be launched IATA SAF Registry which will enable airlines to claim SAF benefits against their regulatory and voluntary obligations, irrespective of where SAF was uplifted. The transparency of a published global standard methodology will give confidence that the Registry is robust and fair, with no double-counting. This is essential in creating a functioning global SAF market,” said Marie Owens Thomsen, IATA’s SVP Sustainability and Chief Economist. Key features include purchase-based emissions calculations, irrespective of chain-of-custody used and SAF uplift locations, aligning with ICAO’s CORSIA approach. It also includes optional tank-to-wake (TTW) or well-to-wake (WTW) emissions factors to meet varying regulatory and voluntary requirements.
