The green supply chain idea has now been implemented and incorporated into production and operations management. Managers and practitioners are interested in green legislation and concepts while selecting suppliers and organizations. A green supplier, green innovation, environmental performance practices in Vietnam’s manufacturing industry are all examined in this study. This is a descriptive research using correlation and structural equation modeling. Management and specialists from many Vietnamese provinces were chosen as study subjects. Study instruments included a questionnaire and Smart-PLS. The results of data analysis demonstrate a positive and significant association between a green supplier, green innovations, and environmental performance of an organization, as well as a negative yet significant relationship. Green innovation and environmental performance have a strong positive association, as does environmental performance and competitive advantage.
