As others have said, this is incorrect. Quickly planning a flight in ForeFlight from LAX direct JFK for a Citation X (a midsize, 12-passenger business jet) at Mach 0.8/FL510 gives a fuel burn of 6700 lbs. The same flight in a 737-900ER (~180 seats in three class configuration) at Mach 0.8/FL390 gives 22500 lbs. Even assuming the Citation has only 6 souls aboard, that's ~1000 lbs/pax for the private jet and ~125 lbs/pax for the 739—"only" 8x worse. Edit: I neglected to convert for the average American's carbon footprint (about 16500 kg CO2/yr as stated elsewhere in the thread). Each of the 6 Citation pax emits (21 lbs CO2/gal * 1000 lbs / 6.7 lbs/gal) = ~3.1k lbs CO2, or ~1400 kg CO2 during the flight—about 1/10 of the average yearly footprint. |
