ICAO has updated the ICAO Carbon Emissions Calculator Methodology. You can access the updated methodology here: .
Depending on user selection for the cabin class (economy, premium economy, business, or first), and where the selected class is available, a multiplicative cabin class factor calculates and applies to the fuel burn to adjust the CO2 (kg) per passenger.
The cabin classes offered (economy, premium economy, business, and first) are based on a dataset provided by Ch-Aviation and determined by the available route pairs, which were approximated according to the Seat Guru database. In cases where a specific cabin class is unavailable, passenger emissions are estimated based on the available cabin classes. This estimation may result in emissions being lower or higher than the actual portion. Additionally, the average emissions for a given route may be influenced by the combination of seat configurations of airlines operating on that route.
