Highlights A two-stage efficiency-oriented decomposition approach is proposed. Factors driving the changes of civil aviation carbon emissions are identified. An empirical study is constructed on 15 international airlines during 2011–2017.
Abstract This study divided the whole process of airline activities into production stage and operation stage to explore the two-stage efficiencies of 15 global airlines. Then a new decomposition approach was proposed to decompose carbon emission changes into seven driving factors, including several efficiency-related factors. The empirical study resulted in three key findings. First, the overall efficiency had clear heterogeneity among different airlines and the values experienced an “up-down-up” trend, which was mainly affected by the total factor energy efficiency change. Second, the transportation load capacity (TLC) and the transportation revenue operation performance (ROP) were the dominant factors driving the increase and decrease of carbon emissions, respectively. Third, the contribution coefficient structures showed different features with different airlines. Four fast-growing airlines were identified as being the main contributors to the TLC effect, while four other well-operated airlines were the main contributors to the ROP effect.
