Nowadays, due to the increasing environmental degradation, paying attention to the environmental aspects of economic activities has become an important goal in the countries all over the world. For this reason, many researchers and economists have assessed the impact of various economic factors on environmental quality. Accordingly, considering the importance of reducing CO2 emissions as the most important indicator of environmental quality on the one hand, and the unavoidable direct and indirect impact of tourism on environmental pollution on the other hand, this study aims to investigate the impact of tourism on CO2 emissions by emphasizing on the mediating role of economic growth, foreign direct investment, and energy consumption in MENA member countries during the period of 1990-2023 applying panel data ARDL and Sobel test. Based on the results, tourism has a positive effect on CO2 emissions in the long and short term with coefficients of 0.658 and 0.132, respectively. In addition, economic growth, foreign direct investment and energy consumption have positive effects on CO2 emissions in the short and long term. Also, the results of Sobel test for economic growth, foreign direct investment and energy consumption were 5.201, 1.962 and 2.274, respectively, which, considering that they are greater than 1.96, show that all three variables have significant mediating role in the relationship between tourism and CO2 emissions. This means that in addition to a direct effect on environmental quality, increased tourism leads to increased economic growth, foreign direct investment and energy consumption, and thus increases CO2 emissions indirectly.
