Corporate Social Responsibility (CSR) has emerged as a critical component of sustainable business practices, particularly for multinational corporations (MNCs) striving to balance profitability with societal impact. This study explores the role of transformational leadership in enhancing CSR engagement within MNCs. By leveraging a mixed-methods approach, we examine how transformational leadership behaviourssuch as inspiring vision, fostering innovation, and promoting ethical standardscan drive more robust CSR initiatives. Through a series of case studies, interviews, and surveys conducted with leaders and employees across various MNCs, we identify key practices and strategies that correlate with heightened CSR outcomes. Our findings suggest that transformational leaders are instrumental in cultivating a culture of responsibility and ethical awareness, thereby amplifying the effectiveness and reach of CSR programs. The study concludes with practical recommendations for MNC leaders seeking to adopt transformational leadership behaviors to bolster their CSR efforts, ultimately contributing to sustainable development and enhanced corporate reputation.
