Environmental, Social, and Governance (ESG) reporting has emerged as a pivotal area of interest for a broad spectrum of stakeholders—including investors, regulators, and consumers—amid rising global expectations around sustainability, accountability, and ethical corporate conduct. Once considered optional, ESG disclosures are now recognized as essential components of strategic decision-making and long-term value creation. This study explores the linkage between ESG reporting and the financial performance of publicly listed companies in India. Utilizing secondary data drawn from company annual reports, ESG ratings, and audited financial statements of selected firms within the NIFTY 50 index, the research investigates whether firms with superior ESG practices demonstrate enhanced profitability, stronger market valuation, and improved investor trust. The analysis reveals a consistent pattern: companies with transparent and credible ESG disclosures tend to achieve better financial outcomes, benefit from reduced capital costs, and enjoy more favourable risk perceptions. These findings underscore the transformative role of ESG reporting—not merely as a regulatory formality, but as a strategic lever for financial resilience and corporate sustainability in the evolving Indian business environment.
