The study is based on the self-determination theory and aims to investigate the mediating role of green intrinsic motivation and the moderating role of green shared vision in the association between frontline managers' green mindfulness and green creative behavior to leverage their capacity to think creatively and act sustainably.The study employs a time-lagged, multi-source research methodology to collect data from frontline managers of service businesses in the tourism and hospitality industry. Data are analyzed using SmartPLS Structural Equation Model to evaluate the structural and measurement models. The authors evaluated the measurement model by employing the criteria of internal consistency: reliability and Cronbach's alpha, validity: convergent and discriminant validity; and the structural model using the path coefficient, coefficient of determination, predictive relevance, and goodness-of-fit metrics.Our findings indicate that green mindfulness significantly improves frontline managers' green creative behavior. Additionally, green intrinsic motivation mediates the connection between green mindfulness and green creative behavior. In addition, the direct effect of green mindfulness on green intrinsic motivation as well as the indirect effect of green mindfulness on green creative behavior through green intrinsic motivation, are both significantly moderated by green shared vision.To the best of the authors' knowledge, this is one of the few efforts that outstretch the boundary conditions of green mindfulness and green creative behavior through the mediating role of green intrinsic motivation and the moderating role of green shared vision.
