Abstract: The current study aims to analyse the relationships between air transportation and carbon dioxide emissions employing the data from 20 countries in different geographical locations to discover the role of the aviation industry impacts on air quality. The analysis was performed by considering pool ordinary least square (POLS), random effect (RE), fixed effect (FE), fixed effect robust, fixed effects Driscoll and Kraay methods using panel data covering years from 1990–2014, to examine the effect of passenger and cargo transportation on environmental quality. Findings reveal that air passenger transportation has a significantly enhances environmental degradation due to a rise in the consumption of fossil fuels, which contributes to an increase in the volume of carbon dioxide emissions. On the other hand, air freight transportation lessens the negative effect of destruction on air quality. The result suggests focusing on new generation aircraft concepts and technologies under fuel strategy scenarios proposed by International Civil Aviation Organization (ICAO) and International Air Transport Association (IATA). Entry to service new generation aircrafts enable use of biofuel with reduced fuel flow which is feasible in order to mitigate CO₂ emission level.
