The latest developments in the tourism sector and the increase in the number of tourists arriving in the host country not only contribute to the economy of the host country, but also cause environmental pollution. The impact of tourists coming to the host country on environmental pollution has begun to be studied by researchers in recent years. Therefore, this study aims to determine the relationship between the number of tourists and CO2 emissions. Extended ECK-Engle and Granger integration test with remains was implemented using annual data for the 1980-2014 period. The matching test results showed that there is a matching relationship between the number of tourists and CO2 emissions. On the other hand, according to the causality test results based on the error correction model, a two-way causality relationship between the number of tourists and CO2 emissions has been identified. The importance of these empirical findings is that the number of tourists increases the amount of CO2 emissions and causes environmental pollution in Turkey. After all, the study suggests that a cleaner environment supports sustainable tourism practices.
