THE RELATIONSHIP AMONG ECO-FRIENDLY TECHNOLOGIES, CIVIL AVIATION AND ENVIRONMENTAL QUALITY: PANEL THRESHOLD REGRESSION ANALYSIS

Abstract

The civil aviation sector is an important type of transportation that connects millions of people, stimulates tourism, and accelerates commercial change, stimulating the economy and bringing cultures together. Especially the speed and the economic power it provides carries the air transportation to the top ranks compared to other types. With the rapid growth of the airline service sector, the issue of climate change attracts more attention due to its increasing negative effects on humans and the earth. Making the national and international air transport system more efficient in order to meet the future demand, the solution is also complex, as the reduction of noise and emissions will affect many stakeholders. Achieving the stated environmental targets of air transport depends on key criteria-based success factors and global efforts. The aim of the study is to investigate the effect of civil air transport on environmental quality. Whether the innovation activities aimed at reducing the climate change related to transportation change the relationship between civil air transportation and environmental quality was examined with the Panel Threshold Value Regression Model between 1979 and 2019 for selected developed European countries. The results show that when technologies that reduce climate change in transportation pass a certain threshold value, the negative impact on the environmental quality of civil air transport disappears.
