Environmental Impact and External Costs Associated with Hub-and-Spoke Network in Air Transport

Under the background of economic globalization, air transport industry developed rapidly. It turns out that city-to-city network has not been able to adapt well development society, and hub-and-spoke came into being. The demonstrates advantages reducing operating costs airlines keep a competitive advantage, by maintaining interests in rapidly developing context. However, during operation aircrafts, they consume fuel spew great deal harmful pollutants air, which an adverse impact on living environment. This paper explores external associated with from environmental perspective. With some mathematical models, we construct take quantitative study transport. For calculating pollutant emissions, meteorological conditions were considered revise emission factors Engine Emissions Data Base (EEDB) published International Civil Aviation Organization (ICAO). measurement model is employed calculate externality toxic gas greenhouse (GHG). In order make more convincing, two alternative networks are computed: network. found poorer because different characteristics scale fleets. Therefore, under general trend green aviation, provides certain reference for airlines’ strategic decision-making.
