Although there have been many studies, focusing on basic determinants of carbon dioxide emissions (CO2), the effect of higher education, which has the potential to be an important determinant of CO2, has been neglected. The paper aims to display the potential mechanisms between higher education and CO(2)and expand the environmental economics literature. In the paper, the trade-off between higher education and CO(2)is tested by autoregressive distributed lag (ARDL) during the period 1983-2017 in Turkey. Results denote that cointegration exists and an increase in higher education negatively affects CO2. We also find that economic growth and energy consumption positively affect CO(2)both in the long run and short run. Vector error correction model (VECM) reveals that higher education, economic growth, energy consumption, trade openness, and exchange rates are the causes of CO(2)in the long run. Also, energy consumption and economic growth are the causes of CO(2)in the short run. Therefore, higher education can be used to overcome environmental problems.
