This paper employed advanced panel methods to examine the effects of international tourist arrivals on CO2 emissions in the Middle East and North Africa (MENA) region over the period of 1995–2018. To analyze the predictive power of tourist arrivals for CO2 emissions, the panel Granger non-causality test was employed. Employing the common correlated effects mean group estimator showed that tourist arrival reduces CO2 emissions, while energy consumption and trade openness are the main contributors of CO2 emissions. Results also showed that although first-generation estimators confirmed the Environmental Kuznets Curve (EKC) hypothesis, according to the CCE-MG estimator, an inverted U-shaped association between economic progress and CO2 emissions does not exist. Furthermore, the null hypothesis of non-Granger causality from tourist arrivals to CO2 emissions was rejected. The findings suggest taking a more sustainable approach to tourism development and energy conservation in the long run.
