Which pollutes more cars or planes?

So, if you're traveling with three or more people, driving is the better option, and here's why: Three people on the cross-country flight would account for 1.86 tons of carbon emissions (0.62 tons of CO2 x 3), compared to the total 1.26 tons of carbon the vehicle would produce (ignoring that the extra weight would ...

CO2 emissions from aviation fuel are 3.15 grams per gram of fuel [1], which gives CO2 emissions from a Boeing 737-400 of 115 g per passenger per km. At a cruising speed of 780 km per hour [Wikipedia, 28.2. 08], this is equivalent to 90 kg CO2 per passenger per hour.
