Abstract
ABSTRACTIn this study, we used a structural equation modelling (SEM) approach to identify the key factors that influence greenhouse gas (GHG) emission reduction potentials in air transport (ERPAT). We explored the correlations among constructs from the perspectives of aviation GHG emission reduction. Organisation type is one of the contextual factors that may change the nature of these correlations. Person- and self-administered questionnaires were used to collect data from 249 aviation experts. The results obtained using SEM showed that aircraft technology and design, aviation operations and infrastructure, socio-economic and policy measures, and alternative fuels and fuel properties are the key factors for reducing GHG emission. Conclusively, organisation type can help in controlling the relationship among the constructs. Thus, organisation type acts as a moderator in the research model. The outputs can be used to measure the level of knowledge and understanding regarding ERPAT and can provide policy-makers, government organisations, and airlines with valuable information for designing appropriate air transport policies for emission reduction.
