This statistic has been compiled from multiple annual reports. The figures in this statistic are for Scope 3 GHG — use of sold products (Commercial aircraft) in a “no SAF” scenario. Use of sold products emissions are based on estimated lifetime emissions of commercial aircraft product deliveries. Estimations include CO₂ emissions only. Emissions related to CH4 and N2O were excluded, given the very low levels produced by modern aircraft engines. Emissions related to NOx were estimated and excluded, given the uncertainty related to the NOx emission factors and the relatively low contribution of this emission stream. CO₂ emission factors for kerosene are the ICAO internationally recognized lifecycle emission factor to be used for baseline fossil jet fuels (3.846 kg CO₂e per kg of fuel for fossil Jet-A/Jet-A1). This factor represents a “well to wake” life cycle analysis to assess the overall greenhouse gas (GHG) impacts of a fuel, including each stage of its production and use.
