Reference in Annex 16, Volume IV: Part II, Chapter 2, 2.2.3. After an aeroplane has monitored its fuel use, the operator is required to determine the CO2 emissions by using the following equation:
CO2 Emissions = Mass of fuel × Fuel Conversion Factor of given fuel type
Fuel conversion factors are:
· 3.16 kg CO2/kg of fuel for Jet-A and Jet-A1 fuel; and
· 3.10 kg CO2/kg fuel for AvGas or Jet-B fuel.
If an aeroplane operator is using the ICAO CORSIA CERT for CO2 emissions monitoring, the tool automatically estimates the CO2 emissions, and no separate calculation of emissions is needed.
