This study examines into how tourists in Sweden engage in sustainable tourism by analysing the impact of personal norms and environmental knowledge on their purchasing decisions, with an emphasis on eco-friendly options for accommodation. The goal of the study is to ascertain how much sustainable tourism practices are considered by visitors in Sweden when making vacation choices. To do this, a survey was given to visitors (both domestic and international) to Sweden, and statistical analysis was done on the data gathered. The study's conclusions show a strong relationship between individual norms, environmental knowledge, and environmentally conscious purchasing practices among Swedish travelers. This shows that more environmentally conscious travelers are more likely to choose sustainable travel options, especially when it comes to choosing eco-friendly lodging. Policymakers, stakeholders in the tourist sector, and marketers wanting to promote sustainable tourism practices in Sweden can all benefit from the knowledge provided by these insights. The development of tailored measures to promote eco-conscious tourism behaviors among visitors to this Scandinavian destination can be aided by an understanding of the interaction between personal norms and environmental awareness.
