Abstract: The present study explores the impact of tourism on environmental pollution using a comprehensive set of air pollutants, namely CO2, CO, NOx, SO2, PM2.5, and PM10, in a multivariate framework under the context of the Mediterranean countries. The panel cointegration tests indicate that there is a long-run equilibrium relationship between environmental pollution, energy consumption, economic development and tourism growth. The tourism-induced EKC hypothesis is validated for four out of six air pollution indicators in the Southern Mediterranean countries, whereas in the Northern Mediterranean region we fail to document any evidence supporting the hypothesis. In addition, tourism growth has a differential impact on different air pollution indicators across regions. The major findings from the panel Granger causality tests show that bidirectional causality exists between four air pollutants (CO2, NOx, SO2, and PM2.5) and tourism and unidirectional causality runs from CO and PM10 to tourism growth in the Northern Mediterranean. In contrast, there is a feedback relationship between environmental pollution (CO and NOx) and tourism growth and one-way causality running from environmental pollution (CO2, SO2, PM2.5, and PM10) to tourism development in the Southern Mediterranean.
