Take a look at www.aee.faa.gov/emissions/airindex.htm At least part of the answer is in there

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:
- carbondioxide
- 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

LH consumes about 4.8 liters / 100 paxkm on the average

charter airlines (with more seats) are well in the 2.5-3.5 liter range
