Hello,
Can anyone help direct me to the right sheet where I can find the "kg CO2-e/tkm" results for burning biojet or H2 in airplanes? Is emissions from "Airplanes" in 'FreightEmissions' tab the right place? (screenshot attached)
Thank you

You are looking in the right place.

The results for a Hefa type biojet are in column BD, an elcohol derived biojet in column BF and a FT type biojet in column BG.

The combustion emissions are in row 13 (Net Operation).

The lifecycle emissions are in row 25.

Thank you for the prompt response, Don!
A follow-up question: if I want to change the fuel economy of the airplane engine, I just update the value in cell BD5 (GJ/tonne-km), is that right?
