Corporate social responsibility (CSR) is the belief that businesses must consider ethical, social, and environmental issues when making decisions. Several studies have found that CSR improves corporate performance. Moreover, CSR is thought to increase con-sumer trust and purchase intention. This study investigates the effect of CSR activities on customers' purchase intentions and the mediating role of trust. It draws linkages and establishes that businesses can improve their bottom lines while positively affect-ing society by acting responsibly. The present study selected two independent variables (ethical corporate social respon-sibility and legal corporate social responsibility) alongside one dependent variable (pur-chase intention) and one intervening variable (trust). The sample comprises two hundred and thirty respondents from India's National Capital Region (NCR), Delhi, and nearby regions. The data were examined using structural equation modeling (SEM). The results showed that CSR activities significantly positively affected customers' purchase inten-tion. Furthermore, trust mediated the linkages between CSR activities and customers' purchase intention. The findings suggest that CSR activities can increase customers' pur-chase intention by fostering trust. In other words, when customers trust a firm, they are more likely to intend to purchase its products or services. CSR managers should there-fore focus on creating and maintaining trust with their customers. In addition, findings suggest that firms should be conscious of their social image. This study offers significant insights because they show that any business can be successful and socially responsible.
