This study investigates empirically an extended version of the Environmental Kuznets Curve model that controls for tourism development. We find that international tourist arrivals into Turkey alongside income, squared income and energy consumption, cointegrate with CO₂ emissions. Tourist arrivals, growth, and energy consumption exert a positive and significant impact on CO₂ emissions in the long-run. Our results provide empirical support to EKC hypothesis showing that at exponential levels of growth, CO₂ emissions decline. The findings suggest that despite the environmental degradation stemming from tourism development, policies aimed at environmental protection should not be pursued at the expense of tourism-led growth.
