The International Air Transport Association (IATA) has introduced a new framework for measuring and reporting carbon emission reductions linked to airlines’ use of Sustainable Aviation Fuel (SAF).
SAF is a crucial element in the aviation industry’s strategy to reach net zero carbon emissions by 2050. IATA’s methodology ensures that the environmental benefits of SAF are recorded with precision, consistency, and transparency, reinforcing its role in aviation’s decarbonization efforts.
This methodology lays the groundwork for the upcoming IATA SAF Registry, set to debut in April 2025. The registry is anticipated to be a pivotal tool in fostering a robust global market for SAF, supporting the industry’s transition toward more sustainable air travel.
“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 Highlights of the IATA SAF Accounting and Reporting Methodology
Emission Calculation Based on Purchase – Ensures accurate emissions tracking regardless of the SAF supply chain or point of uplift, aligning with ICAO’s CORSIA standards.
Flexible Emission Factors – Provides the option to use either tank-to-wake (TTW) or well-to-wake (WTW) emission factors to meet diverse regulatory and voluntary reporting needs.
Uniform Accounting Framework – Establishes a standardized approach to support both regulatory compliance and voluntary sustainability initiatives.
No Bias on Additionality – Allows claiming parties to account for SAF emission reductions without predefined restrictions, as long as double-counting is prevented.
Passenger and Cargo Considerations – Offers specific guidance on calculating SAF-related emission reductions per traveler and per shipment.
Core Principles:
Fair and Equal Treatment – Ensures a level playing field for all stakeholders.
Elimination of Double Counting – Prevents duplicate claims on emission reductions.
Credibility in Reporting – Maintains integrity in sustainability claims.
Data Transparency and Verification – Supports clear and auditable emissions reporting.
Developed with insights from over 40 airline specialists worldwide, IATA’s SAF methodology remains neutral to feedstock types and technological pathways. It is designed to align with international sustainability frameworks, enhancing consistency while avoiding redundant processes.
