    1. Aviation Gasoline: 18.355 pounds CO2 per gallon or 2.199 kg CO2 per liter.
    2. Jet Fuel: 21.095 pounds CO2 per gallon or 2.527 kg CO2 per liter.
    3. Kerosene: 21.537 pounds CO2 per gallon or 2.580 kg CO2 per liter.
    4. Aviation gasoline is Av-gas = 100 Octane Low Lead Aviation Fuel (for reciprocating or piston engines)
    5. Turbine engine aircraft can burn Jet-A , Jet-B fuel or Kerosene
    6. Jet-B has a small amount of naphtha in it; Jet-A has no naphtha in it
    7. Turbine aircraft in Yellowknife use primarily Jet-A which is a clean kerosene

    Given the above, I used the "Jet Fuel" emission rate of 2.527 kg CO2 per liter for Turbine aircraft and 2.199 kg CO2
