Small emitters tool (SET) - 2021

Emissions calculator

The small emitters tool (SET) is updated on a regular basis with fuel burn samples provided from volunteer aircraft operators yearly in order to make it as accurate as possible and consistent with real life operations.

Different versions of the tool are available depending on the year the flight was operated. Version 5.11 is to be used for flights operated in 2021.

Many changes in the SET methodology have been made this year. As a consequence it is strongly recommended to use the tool as it is.

Do not try to reverse engineer the tool’s computations, results will be most likely inconsistent and incorrect. In case you are interested with the detailed equations for integration into your own tool/platform or for more global studies, please contact us with your motivations via the contact form on this page.
