This study aims to examine the relationships among environmental sensitivity, eco-anxiety, and sustainable consumption behavior, thereby revealing how these variables interact within the framework of sustainability psychology. Conducted with a sample of 406 university students in Türkiye, the research employed a quantitative and cross-sectional design, and the proposed relationships were tested using structural equation modeling (SEM). The findings indicate that environmental sensitivity significantly predicts sustainable consumption behavior both directly and indirectly through eco-anxiety. Eco-anxiety was found to play a partial mediating role in the relationship between environmental sensitivity and sustainable consumption. In addition, the moderating effect of gender was investigated, and no significant differences were observed between women and men regarding the structural paths of the model. Overall, the results demonstrate that sustainable consumption behaviors are shaped not only by cognitive processes but also by emotional mechanisms, suggesting that eco-anxiety, as a motivational emotional response, may strengthen sustainable behavior. This study contributes to the environmental psychology literature by theoretically and empirically highlighting the decisive role of emotional processes in shaping sustainable behavior. The findings also provide important practical implications for sustainability policies, environmental education, and communication strategies.
