Abstract

: The transportation industry is one of the most influential sectors in the economy of any country, and its role in the spread of pollution is no secret to anyone. Meanwhile, aviation is the second largest producer of greenhouse gas emissions, responsible for approximately 2 to 4 percent of total human emissions. Carbon emissions from the aviation sector are more dangerous than other transportation activities, because they both distort the composition of the atmosphere at high altitudes and intensify the concentration of greenhouse gases in the surface environment. Therefore, considering this important issue, the present study examines the effect of aviation, along with energy consumption, economic growth, and urban population, on CO2 emissions, in the framework of the Kuznets environmental hypothesis. To achieve this goal, data from BRICS member countries from 1990 to 2022 were used and the Dynamic Ordinary Least Squares (DOLS) method was used for estimation. The results of this study showed that the environmental Kuznets hypothesis was confirmed among BRICS member countries during the period under study. The results of this study also showed that air transport and energy consumption have a positive effect and urbanization has a negative effect on CO2 emissions. According to the results, it is suggested that clean and environmentally friendly energy sources be used in the transportation sector
