IATA has developed a methodology for calculating CO2 emissions based on passenger weight. According to the head of the association, Willy Walsh, this methodology is the most accurate of all currently existing. It allows you to determine the amount of CO2 emissions per passenger for a particular flight, Tengritravel.kz reports with reference to 4Hoteliers.
As IATA CEO Willie Walsh clarified, the development was carried out jointly with airlines.
“The methodology is designed for organizations and individuals to make informed choices about environmentally friendly flying. This includes decisions to invest in voluntary carbon offsets or sustainable aviation fuel (SAF) use,” he added.
The IATA methodology takes into account the following factors:
– guidelines for measuring fuel consumption under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA),
– a well-defined scope for calculating CO2 emissions from airline operations,
– guidance on non-CO2 emissions and Radiative Forcing Index (RFI),
– principle of calculation by mass: distribution of CO2 emissions by passengers and cargo compartments,
– passenger weight guide using actual and standard weight,
– emission factor for converting jet fuel consumption to CO2, fully harmonized with CORSIA,
– weighting cabin classes, as well as accounting for different configurations of airline cabins.
According to IATA, there are now different methodologies for determining carbon emissions with different results, which creates confusion and undermines consumer confidence. At the same time, aviation aims to achieve zero emissions by 2050.
“By developing a globally accepted industry standard for calculating aviation carbon emissions, we are providing significant support to achieve this goal. The IATA Passenger CO2 Emissions Methodology is the most authoritative tool and is ready for use by airlines, travel agents and passengers,” said the head of the organization. Willie Walsh.
