Re: Railways, energy, CO2 - Part 1 (4.00 / 3)

You might like this:
http://konzern.lufthansa.com/en/downloads/presse/downloads/publikationen/lh_sustainability_2007.pdf

Its a sustainability report from lufthansa. On page 3 they show total fuel burn and fuel burn per paxkilometer, plus some other stats about CO2, NOx etc.

From what I know, Lufthansa is pretty reliable in this respect. They put fuel consumption at 4.38 litre/(100 paxkm), and CO2 emissions at 11 kg/(100 paxkm), so that's
110 g/paxkm.

That's less than your figures, but these are fleet averages, and I think they will somewhat higher when focussed on short-range flights only.

A quick reply without looking into the Lufthansa report:

Distsance is indeed a main factor, figures for airplanes reduce once we move out to international connections
Seat occupation is another, maybe Lufthansa's are above average
Tricky part 1: is fuel production involved in Lufthansa's figures, or only end-use?
Tricky part 2: is it l gasoline, or l kerosene?
DB may have been tricky too: those figures might involve emissions from airplane production, but not from train production (will check for a third part of this diary series)
