Tourism, contributing to the economic development of both developed and developing countries, includes environmental, social and economic dimensions of sustainable development with this structure. Therefore, analyzing tourism development and environmental quality nexus is a crucial issue for policymakers to design effective policies for a sustainable life. The main purpose of this study is to investigate the impacts of tourism investments on the ecological footprint in the six countries (Ecuador, Egypt, Turkey, Uzbekistan, Tunisia and Sri Lanka), which are in the top 20 countries, fastest-growing in terms of tourism GDP over the period of 1995-2014. In addition to tourism investments, our quadratic EKC model includes economic growth, energy use and individual internet use as independent variables. Empirical findings reveal that tourism investments and internet uses have negative impacts on ecological footprint. On the other hand, energy consumption increases environmental degradation. Also, the existence of the EKC is confirmed in these countries. © The Author(s) 2021.
