The tourism industry is one of the leading industries in the world. Tourism that contributes to economic growth and development is increasing its share among the sectors day by day due to globalization, population growth and technological advances in the transportation and communication sector. Developments in the tourism sector, which is of great importance in terms of national economies, can cause effects not only in the economic dimension but also in the environmental dimension. In this study, the relationship between tourism and CO2 emission, which is used as an indicator of environmental pollution in Turkey, is discussed. The long-term relationship between tourism and CO2 emissions is examined with the Johansen cointegration test with annual data for the period 1990-2018. In this study, in which empirical analysis methods are used, the unit root level of the variables is tested first. Johansen cointegration test is applied to determine whether there is a cointegration relationship. After determining the existence of the cointegration relationship between the variables, long-term coefficient estimators are used. Similar findings are obtained as a result of FMOLS, DOLS and CCR methods. The findings are that tourism increases CO2 emissions and causes environmental degradation.
