This study explores the role of information technology (IT) in advancing sustainability efforts across various sectors in India. As India pursues its commitment to the United Nations Sustainable Development Goals (SDGs), the integration of digital technologies into corporate sustainability strategies has become both imperative and challenging. Through an analysis of four Indian case studies, this research investigates how firms are leveraging technologies such as the Internet of Things (IoT), blockchain, and artificial intelligence (AI) to promote energy efficiency, resource optimization, and waste reduction. Findings indicate a growing trend towards green innovation, particularly in sectors like manufacturing, agriculture, and urban development. These technological interventions align with national frameworks such as the Digital India initiative and the National Action Plan on Climate Change (NAPCC), emphasizing the need for stronger digital infrastructure and skill development. Furthermore, the study underscores the importance of policy support, regulatory clarity, and public–private partnerships in fostering environmentally sustainable practices. The case studies exemplify how IT serves not only as a technological enabler but also as a strategic driver of sustainable transformation in India. Building institutional capacity and removing technological and financial barriers are critical to ensuring the scalability of these practices nationwide. Overall, the research highlights the transformative potential of IT in achieving India’s sustainability goals through innovation, integration, and inclusive development.
