Abstract
The tourism industry has long been accused of being the major driver of global warming as a result of the size of the industry and its subsequent high energy consumption, most of which comes from sources that emit carbon dioxide. However, in spite of the criticism directed towards tourism due to its negative effects on the environment, there is a scarcity of research that has aimed to ascertain its impact on the environment, thus revealing the existence of a gap in the literature. The current study uses a dynamic GMM model for 38 OECD countries from 2008 to 2019 for the purpose of filling the gap in the literature by investigating the effects of tourism development on the environment, as well as ascertaining the role of renewable energy in mitigating environmental impact. Unlike past studies that have alluded to the fact that tourism development exacerbates the emissions of carbon dioxide and hence global warming, the current research shows that in the OECD countries, tourism does not have any significant link with greenhouse gas emissions. This is because OECD nations have long started to shift from the use of fossil fuels to renewable sources of energy that do not exacerbate greenhouse gas emissions. However, the current research concurs with the findings of past studies that renewable energy consumption significantly decreases greenhouse gas emissions. The use of renewable energy sources instead of fossil fuels should continue to be encouraged in all nations for the purpose of achieving the carbon neutrality goal of the United Nations.
