Purpose: This study aims to examine the influence of sustainability education in 15 Indian universities and the mediating role of the theory of planned behavior in predicting students' intentions to start an enterprise supporting sustainability. Design/methodology/approach: The data, which consists of 422 samples, was collected from 15 universities in India. It was analyzed through partial least squares structural equation modeling, which is frequently used for prediction models. The model was further checked for goodness-of-fit using Amos. Findings: The results suggested that personal and subjective norms play a mediating role in shaping the intentions of students to choose entrepreneurship in the sustainability field. Education on sustainability has a significant influence on personal and subjective norms, and these norms further help to develop entrepreneurial intentions. Practical implications: The study will be helpful for researchers and universities in understanding the importance and stake of including courses on sustainability. Social implications: As the results suggest, social norms play a significant role in determining entrepreneurial intentions; therefore, the study will develop a societal culture of start-up education and ethos. Originality/value: The research is original and one of the first to examine the mediating role of the theory of planned behavior on the relationship between education and intentions to start a sustainable enterprise.
