This dataset represents the 1 t·km freight transport service process using aircraft (passenger-cargo combi or full-freighter). The dataset covers the entire transport life cycle, including freight transport as well as the construction and operation of the airport. The scope of the dataset is limited to the operation of the aircraft, and its input data include fuel consumption (and its associated emissions) and airport facilities (i.e. the construction and operation of the airport are included in the associated dataset). The associated emissions, including carbon dioxide and carbon monoxide emissions, are calculated based on fuel consumption and the emission factors derived from fuel consumption in "Research on Aircraft Fuel Consumption Models and Pollutant Emissions Based on Flight Data" and "Urban Mobile Source Pollutant Emission Inventory and Characteristic Analysis".
