ABSTRACT

Over the last four decades the contribution of transportation to total energy use and carbon dioxide (CO2) emissions in the Turkey increased in absolute and relative terms. So, this study tried to determine the effect of freight transportation in different transport modes on carbon emissions in Turkey from 1970 to 2019. For this purpose, carbon dioxide is used as a dependent variable, and the amount of freight transported by airline, road, rail, and sea are included as independent variables in the analysis. According to the results of the Autoregressive Distributed Lag (ARDL) bounds testing method in the study, it was determined that there is a cointegration relationship between the dependent variable and the independent variables. In addition, only the amount of cargo transported by road is statistically significant and positively affects carbon emissions. The error correction coefficient is in line with the theoretical expectations, has a negative sign, and is statistically significant. The diagnostic test results for the model reveal the accuracy and reliability of the model.
