Paul wonders if flying is not better than driving; he has seen a statistic of 5 gallons jet fuel per passenger on a flight, vs an estimated 150 gallons gasoline for driving a similar distance. He thinks better data is needed about carbon emissions from various modes of transport.

CO2 emissions from a gallon of gasoline : 8887 grams / gallon
CO2 emissions from a gallon of diesel : 10180 grams / gallon
