This chapter shows the outcomes of field research that measured the effect of institutional support for developing entrepreneurship (ISDE) and country support for entrepreneurship (CSE) through entrepreneurial self-efficacy (ESE) on green entrepreneurial intention (GEI). 389 business students in Colombia completed the questionnaire using an online platform. Twenty-four questions measured the GEI. The study used SEM-PLS technical analysis. It was found that ISDE (0.224) and CSE (0.161) had a positive and significant effect on ESE, and ESE had a positive effect (0.705) on GEI. The model explained 49.7% of GEI. The information from the current study can be used to create new plans and strategies by university authorities.
