Estimates of U.K. CO2 Emissions from Aviation Using Air Traffic Data

The allocation of CO2 emissions to specific sources is a major policy issue for international aviation. This paper addresses this problem by recommending a possible methodology for calculating air transport carbon dioxide (CO2) emissions using detailed air traffic data. The basis for the calculations is an air traffic sample for one full-day of traffic for the UK. In order to analyze aircraft fuel burn use and hence CO2 emissions, the Reorganized Air Traffic Control Mathematical Simulator (RAMS Plus) and the Advanced Emission Model (AEM III) are used. The results from these detailed simulations are compared with two of the most widely-used aviation CO2 emission estimates to have been made for the UK: the SERAS study and NETCEN estimate. Their estimates for the year 2000 are 26.1 Mt and 31.4 Mt, respectively. In addition, the most recent NETCEN estimate for the year 2003 is 34.1 Mt of CO2. Our estimate of total aviation CO2 emissions, using detailed simulations and real air traffic data, is 34.7 Mt for the year 2004. Furthermore, contributions of the most polluting flights and aircraft are identified. International departures dominate; six percent of flights account for 50 percent of total emissions. The most polluting aircraft per flight-km are B747 aircraft. Different methodologies and their implications are also discussed.
