How are aircraft CO2 emissions calculated?
Aircraft CO2 emissions are an exact multiple of fuel consumption.
To calculate fuel consumption there are two different approaches for aviation (Method A and Method B).
CO2 emissions are then calculated by multiplying the mass of fuel by the emission factor:
EMISSIONS = Fuel Consumption (in tonnes) × Emission Factor (in CO2 kilograms per tonne of fuel)
| Type of fuel | Emission factor (tCO2/tFuel) |
|---|---|
| Aviation Gasoline (AvGas) | 3.10 |
| Jet gasoline (Jet B) | 3.10 |
| Jet kerosene (Jet A1 or Jet A) | 3.15 |
