Green hotels have grown in popularity due to customers' increased awareness of environmental issues. This study aims to construct and evaluate a model that combines the theory of Planned Behavior (TPB) and the theory of ethics to explain green hotel visitors' intentions and behavior. The study also considers the role of trust & subjective norms as a moderator. The framework of the study was evaluated using a quantitative method. Most of the respondents to the study, which was carried out in Noakhali, Bangladesh, were students at Noakhali Science and Technology University and their family members. The data was collected from 414 respondents and analyzed using the structural equation modeling (SEM) technique. The data collection took around two weeks, starting from December 3, 2021. According to the study's findings, the deontological (Moral obligation and justice) and teleological variables (perceived benefit and perceived risk) significantly influence green hotel visitors' intentions and actual behavior. Moreover, trust noticeably influences the relationship between subjective norm (SN) and Intention, and subjective norm affects the connection between attitude and intention. Therefore, hotel management can utilize this research to examine and understand visitors' intention and actual behavior to visit green hotels, which will assist them in attracting guests by portraying their services as eco-friendly. Furthermore, the findings may help hotel management formulate competitive marketing strategies, design effective promotional tools, and help generate an eco-conscious customer base.
