myclimate has updated the online flight calculator

myclimate gives its customers the opportunity to calculate emissions generated by flights and to offset these via carbon offset projects on the platform at de.myclimate.org/flugrechner. Using current data from the aviation industry and with adjustments to the methodology in line with international norms, myclimate has now brought this service up to date.

The environmental team from myclimate adapted the flight emissions calculator in a large-scale project with the help of current studies and data from the aviation industry.

This has changed

The calculation is based on updated data regarding aeroplane types and their specific fuel consumption and number of seats, as well as the average occupancy of the flights. The data cover all major international airlines. The data basis for this calculation is provided by the International Civil Aviation Organization,ICAO, an agency of the UN. The new myclimate flight calculator also records the emissions linked to the infrastructure at airports, as well that related to the aeroplanes themselves (production, maintenance, disposal).

Further adjustments concern “extra mileage”, that is the additional kilometres flown per flight due to air traffic control or general queues for take off and landing. The freight too is now allocated using a new method according to its mass. Likewise the kerosene production in the upstream chain has been more precisely calculated using new data.

The evaluation of additional non-CO₂-producing emissions, undertaken using the RFI factor (Radiative Forcing Index), remains unchanged. The myclimate approach has recently been corroborated by a study by Jungbluth et al. on the calculation of flight emissions.
