How to decouple tourism growth from carbon emission? A panel data from China and tourist nations
Abstract
A pervasive threat regarding human health, ecological balance, progress, and sustainability marks the current era. Many nations are grappling with the consequences of the overabundance of carbon emissions from a wide range of destructive human activities, which is the primary driver of air pollution, global warming, and warming. Thus, while some countries are squandering their riches, others are making great strides to keep the environment clean and green so that future generations may thrive. National governments and policymakers are now focusing a lot of energy on addressing the dangers posed by environmental concerns and the threat of climate change. A very contentious issue in recent years has been the link between environmental change and tourism and its vulnerability. This study focuses on the impact of fluctuating visitor numbers on greenhouse gas emissions, the primary gas responsible for the acceleration of global warming and other environmental changes. Therefore, we look at how the most visited countries' carbon emissions have changed due to increased tourism. The ecological effects of tourism on a regional scale are investigated using a panel data analysis spanning the years 2001–2018 in China, including the top 80 countries. The best-modified assessment methodologies determine the overall, direct, and indirect impact of tourist spending on carbon emissions. The findings demonstrate that CO2 emissions might be reduced by environmental regulation, urbanization, and tourist revenue and that they could be increased through economic expansion, population, and tourism. Due to this distinction, tourists' overall impact is much more harmful than their direct impact. In addition, a U-shape is formed by the direct effects of carbon emissions and a growing economy, and vice versa. Several factors impact environmental regulation, including population density, population growth, pollution, and GDP growth. Spending on infrastructure development and economic expansion also considerably mitigates the impacts of tourism and environmental alteration. The results reveal that a nation's emissions often rise with the expansion of its tourism industry. Still, they begin to decline after certain levels and show that the link between the two has important policy implications.
