This research intends to look into the connection between Thailand's tourist industry and environmental quality. This study specifically examines how tourism industry and trade sector affect the environmental quality in Thailand. The objectives of the study are to assess how trade and tourism affect the environment and to provide suggestions for environment friendly travel habits. The autoregressive distributed lag model was used in the research to analyze in both the long- and short-term links between environmental quality, tourism, and trade in Thailand. The study's statistics, which span the years from 1995 to 2021, were taken from the World Bank database. According to the study's results, Thailand's trade and tourism are significantly inversely correlated with environmental quality. Based on this research, both the short- and long-term effects of increased trade and tourism are a reduction in the country's environmental quality. By presenting factual proof of the damaging effects of commerce and tourism on Thailand's ecosystem, the research adds to the body of previous material. The report also emphasizes the need for decision-makers to implement environmental protection laws and sustainable tourism practices in order to lessen the damaging effects of trade and tourism on the environment. The study's conclusions suggest that the Thai government gives concentration in implementing environment friendly tourist practices a higher priority. To further guarantee that the detrimental effects of trade and tourism on the environment are kept to a minimum, the government should think about enacting environmental protection measures. The paper concludes by recommending more research be conducted to examine how other elements, such as technology, may affect Thailand's environmental quality.
