Agri-food business supply chains have been persistently evolving with humans for ages. In the current era, environmental regulations (ERs) and corporate social responsibility (CSR) play vital roles in ensuring green supply chain management (GSCM) in the agri-food business. Therefore, this study explores the relationship between ERs and GSCM with the mediating role of CSR between these variables. ERs have two types, including command and control type (CCT) and market-based type (MBT). We used a survey questionnaire approach to collect data from the representatives of the target population. Using the convenient sampling technique, a total of 300 responses were subjected to data analysis. Partial least square structural equation modeling was applied using SmartPLS. The results indicated that CCT has a positive, direct and significant effect on GSCM in the agri-food business. Similarly, the MBT also has a significant and positive effect on GSCM. Furthermore, the results indicated that CSR played a mediated role in the relationship between CCT and GSCM. Similarly, the results indicated that CSR played a mediated role in the relationship between MBT and GSCM. Based on these results, theoretical guidelines and managerial implications were discussed for corporate GSCM in the agri-food business.
