IATA announced the launch of the IATA Recommended Practices Calculation Methodology for the calculation of CO2 per passenger.
Using verified airline operational data, the methodology is designed to provide an accurate calculation allowing the industry to quantify the CO2 emissions per passenger for a specific flight.
As travelers, business travel managers and travel agents increasingly demand accurate information on CO2 emissions from flights, an accurate and standardized calculation methodology is essential. This is especially true in the corporate sector where such calculations are needed to underpin voluntary emission reduction targets.

“Airlines have worked together through IATA to develop an accurate and transparent methodology using verified airline operational data. This provides the most accurate CO2 calculation for organizations and individuals to make informed choices about sustainable flight, including decisions about whether to invest in voluntary carbon offsetting or sustainable use of aviation fuel (SAF),” said IATA Director General Willie Walsh.
The IATA methodology takes into account the following factors:
– Guidance on fuel measurement, aligned with the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA).
– Clearly defined scope for calculating CO2 emissions related to airline flight activities.
– Guidance on non-CO2 emissions and Radiative Forcing Index (RFI).
– Calculation principle based on weight: breakdown of CO2 emissions by passengers and cargo.
– Guidance on passenger weight, using actual and standard weight.
– Emissions factor for converting jet fuel consumption to CO2, fully aligned with CORSIA.
– Cabin class weightings and multipliers to reflect different airline cabin configurations.
– Guidance on SAFs and carbon offsets in the context of CO2 calculation.
“The plethora of carbon calculation methodologies with varying results creates confusion and undermines consumer confidence,” Walsh added. “Aviation is committed to achieving net zero by 2050. By creating an accepted industry standard for calculating aviation carbon emissions, we are putting in place critical support to achieve this goal. The IATA Passenger CO2 Calculation Methodology is the most reliable tool and it is ready to be adopted by airlines, travel agents and passengers. »
