Flying-General (Emissions from a single passenger)

(Source) The average passenger miles per gallon for a domestic or international trip originating in the U.S. equals 33.4, according to “Transportation, Energy, and the Environment”, Section A – U.S. Energy Consumption and Transportation Sector Energy Consumption, Table 4-21. (Note that this is not much better than the average automobile, if driven with only one occupant.)

Burning a gallon of jet fuel releases 21.095 lbs of CO2. Combining these two factors:

Based on the Climate Neutral Network’s analysis, an additional 8% has added to the total to account for the emissions associated with the upstream refining of jet fuel. The result is that 1.36 lbs. of CO2e are created for each passenger mile traveled (0.63 x 2 plus 8%). It is important to note that many carbon calculators on the Internet, do not account for these additional emissions and hence, significantly underestimate total Greenhouse Gas emissions. (Source)

[Note: The ‘upstream’ CO2 footprint could be as much as 31.35% which includes extraction of crude oil, transport to refinery, refining to jet fuel, transport to airports, storage, etc. making a grand total of about 1.66 lbs. (751g) of CO2e for each passenger mile traveled.]
