This study aims to determine the structural relationships between environmental, social and governance (ESG) performance in sports complexes, along with external factors and motivations (social influence, facilitating conditions, hedonic motivation, price value, habit), with tourists’ behavioural intentions. Design/Method/Approach: To achieve this, a web- based survey was conducted, and after eliminating outliers, data from a total of 541 responses were analysed using the SPSS and AMOS statistical software packages. Findings: The research findings indicate a positive correlation between environmental and social performance in sports complexes, along with external factors and motivations (social influence, facilitating conditions, hedonic motivation, price value, habit), and tourists’ behavioural intentions. Hedonic motivation and habit have been identified as the most crucial. Additionally, past experience moderates the impact of social influence, facilitating conditions, hedonic motivation, price value and habit on tourists’ intentions. Conclusions/Recommendation: This study suggests that enhancing tourists’ hedonic motivation and cultivating consumer habits are crucial for improving tourists’ intentions to visit sports complexes. Furthermore, efforts should be directed towards improving sports complexes’ environmental and social performance, enhancing the social environment and convenience, and increasing their cost- effectiveness to boost tourist intention. Originality/Value: This research represents a significant revision of the UTAUT2 model, expanding its applicability. Moreover, it is the first attempt to employ ESG theory to explain tourists’ behavioural intentions in sports complexes.
