A rough rule of thumb (but there are many variables): 50 seat-miles per US gallon (20 seat-km per ltr).
The fuel is for well over 99% converted to:
- water vapor
(the same as your lungs emit).
In addition small amouts of:
- hydrocarbons (soot)
- sulphurdioxide (doesn't smell good - in addition to hydrogen and carbon jet fuel contains roughly 0.2% sulphur)
And two very unstable and shortlived gasses:
- carconmonooxide (a killer gas)
- nitrogen oxide - often called NOX (not healthy either).
Emition profile is very much the same as a diesel truck or bus, except that in your country, Norway, and several other countries diesel fuel is by law fomulated to have a much smaller sulphur contents. Which makes diesel fuel somewhat more expensive to produce.
Always keep your number of landings equal to your number of take-offs
