Resumo: The awareness of tourism’s environmental impact has increased interest in sustainable alternatives such as green hotels, yet tourists often fail to translate pro-environmental attitudes into action, reflecting the attitude–behavior gap. This study extends the Theory of Planned Behavior (TPB) by incorporating Environmental Knowledge and Climate Change-Related Risk Perceptions (CC-RRPs) as background factors and testing their effects on Green Hotel Purchase Intentions (GHPIs) among Spanish travelers. Data from 1442 respondents were analyzed using covariance-based Structural Equation Modeling (SEM) with bootstrapped mediation testing. Results show that In-Group Norms are the strongest predictor of GHPIs, followed by Eco-Hotel Attitudes, while Perceived Behavioral Control (PBC) has a weaker but significant effect. Environmental Knowledge predicts all three mediators, and CC-RRPs predict Attitudes and Norms but not PBC. Crucially, both antecedents affect GHPIs only indirectly, supporting a mediation-based framework. These findings clarify the distinct roles of Environmental Knowledge as a cognitive antecedent and CC-RRPs as cognitive–affective evaluations that motivate attitudes and norms, while also highlighting the centrality of social influence in a Southern European context. Beyond theoretical contributions, the results underscore the importance of trust and authenticity: addressing greenwashing through transparent communication and credible certification frameworks is essential to ensure sustainable hospitality choices. © 2025 The Authors
