This paper aims to analyze the influence of sustainability education, knowledge, and attitude on student environmental sustainability behavior. This study also analyzes the influence of sustainability education on sustainability knowledge and attitude. With the PLS-SEM approach, this study took the object of students of Universitas Negeri Semarang (UNNES). A total of 256 students from five faculties have participated in filling out the research questionnaire. Validity and reliability analysis have been carried out, and continued with goodness-of-fit analysis and hypothesis testing (direct and indirect effects). The results of the study indicate that sustainability education has a positive effect on sustainability knowledge and attitude. Sustainability education has not been proven to have a direct effect on student environmental sustainability behavior. Sustainability education will affect students' environmental sustainability behavior through their sustainability attitude. Other results indicate that sustainability knowledge is also unable to determine student environmental sustainability behavior significantly. Sustainability knowledge will be able to determine student environmental sustainability behavior significantly if through sustainability attitude. Finally, a sustainability attitude has a positive effect on students’ environmental sustainability behavior. This study pays attention to the importance of a sustainable attitude, which can act as a significant predictor and mediator.
