Quote:My rough calculations are that it takes about 3,337 lbs CO2 to fly there with my family and it takes about 24 gallons of gas to drive there at 25 lbs of CO2 / gallon or 600 lbs of CO2 total.
In the in flight magazines of some carriers they show the fuel/per seat per km. I believe on average it was around 35 ml per km/seat (for a ful plane) This would mean around 28 kmter. Travelling alone would give you roughly the same CO2 exhaust fro flying as for driving an (for todays standards) efficient car. Of course depending on where you have to be and if the road is curvy and or hilly.
