This study examines the validity of the environmental Kuznets curve (EKC) hypothesis through energy consumption in Turkey and in neighboring countries for the period of 1971–2014 for Turkey and Iran; and the period of 1980–2014 for Bulgaria. Autoregressive Distributed Lag (ARDL) bounds test is used to display the relationship between variables in the study. The results support that the EKC hypothesis has long term validity in Turkey. However, it is invalid in Iran, and Bulgaria. In other words, there is a U type relationship for Iran and Bulgaria. In addition, it can be said that energy intensity increases environmental degradation through CO
