ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG) AND FIRM PERFORMANCE: EMPIRICAL EVIDENCE FROM INDIA

Abstract

India, as the world's fifth-largest economy and home to over 1.4 billion people, faces unprecedented sustainability challenges while pursuing rapid economic growth. Recent regulatory developments, including SEBI's mandatory Business Responsibility and Sustainability Reporting (BRSR) framework and the Companies Act 2013's CSR provisions, have positioned India at the forefront of emerging market ESG integration (Bergman et al., 2019). Despite this regulatory momentum, India ranks 120 out of 165 countries on Sustainable Development Goals progress (Sultana, 2021), revealing a critical implementation gap between policy intent and ground reality. Furthermore, while global ESG research has proliferated, emerging markets—particularly India— remain significantly underexplored, with existing literature predominantly focusing on developed economies (Alshehhi et al., 2018). This geographic concentration creates a substantial knowledge gap, as institutional differences in emerging markets may fundamentally alter ESG-performance relationships compared to Western contexts. Against this backdrop, the present study addresses critical research gaps identified through systematic literature review. First, despite extensive scholarly attention, the ESG-firm performance relationship remains inconclusive, with evidence suggesting positive (Kim & Li, 2021), negative (Saygili et al., 2022), and neutral (Chen et al., 2021) associations. Second, limited research investigates mediating and moderating mechanisms explaining when, how, and why ESG affects performance (Duque-Grisales & Aguilera-Caracuel, 2019; Gao et al., 2019). Third, most studies focus on aggregate ESG scores rather than dissecting individual Environmental, Social, and Governance pillars, despite each potentially exerting unique influences (Dong et al., 2022; Zhou et al., 2022; Paolone et al., 2021). Fourth, prior research employs either accounting-based or market-based performance measures, but rarely integrates both perspectives comprehensively (Carnini Pulino et al., 2022; Richard et al., 2009). Fifth, ESG research predominantly relies on regression analysis, while mixed-method approaches capitalizing on qualitative and quantitative strengths remain unexplored (Dawadi et al., 2021; Malina et al., 2011). Lastly, the geographic concentration in developed markets leaves emerging economies underrepresented in ESG discourse (Sultana et al., 2018). To address these gaps, this comprehensive study investigates the relationship between ESG practices and firm performance among NIFTY 500 companies in India from FY 2015 to FY 2023, employing a sequential mixed-methods approach. The research encompasses three distinct yet interconnected analytical phases: text mining analysis of sustainability reports from 269 companies to examine ESG behavioral patterns, panel data regression modeling to establish empirical relationships between ESG dimensions and performance metrics, and qualitative case studies with ESG professionals from 11 top-performing firms to explore implementation strategies and challenges. The text mining analysis conducted using Orange software with a minimum 1,000-occurrence frequency threshold applied to over 200,000 keyword instances, reveals that Governance dominates ESG discourse, followed by Social and Environmental dimensions, indicating Indian corporations' emphasis on transparency, oversight mechanisms, and stakeholder engagement. The quantitative analysis examines relationships between ESG performance—measured through standardized Bloomberg ESG scores (Tamimi & Sebastianelli, 2017; Shaikh, 2022)—and three dimensions of corporate outcomes: financial performance (revenue growth, profit margins, ROA, ROE, ROCE), market performance (Tobin's Q, P/E ratio, P/B ratio, EV/EBITDA), and shareholder value creation (EVA, MVA). Addressing the mechanisms gap, the study incorporates moderating variables (financial slack, internationalization, board gender diversity) and mediating variables (operational efficiency, innovation, risk management) to understand when and how ESG initiatives translate into performance improvements. Empirical findings demonstrate that ESG impacts are highly contextual, with substantial heterogeneity across ESG components, performance metrics, and industry classifications. Consumer non-cyclical industries consistently exhibit the most positive ESG-performance relationships, while basic materials sectors face inherent implementation challenges, thereby explaining previous contradictory findings through sectoral analysis. Individual component analysis—examining Environmental, Social, and Governance pillars separately—reveals that Governance and Social dimensions exert stronger influence on firm performance compared to Environmental factors (Cek & Eyupoglu, 2020; Paolone et al., 2021), potentially reflecting India's position on the Environmental Kuznets Curve where environmental investments have not yet reached the turning point for positive financial returns (Vasanth et al., 2015; Alam & Adil, 2019). Financial slack emerges as a significant moderator in five industries, while internationalization demonstrates complex moderation patterns with positive effects in four industries but negative effects in three sectors (Duque-Grisales & Aguilera-Caracuel, 2019). Board gender diversity positively moderates relationships in technology, consumer non-cyclical, and utilities sectors (Zhu & Chen, 2024; Romano et al., 2020). Operational efficiency shows the strongest mediation effects, positively mediating across six sectors (Wang et al., 2025; Iazzolino et al., 2023), while innovation and risk mediation reveal sector-specific patterns (Tang, 2022; He et al., 2023). The qualitative case study analysis, employing reflexive thematic analysis through NVivo 14 on semi-structured interviews with ESG professionals, yields seven major themes: organizational understanding and perspective of ESG, environmental practices and climate disclosures, social impact and community initiatives, governance structures and board composition, barriers to strategic ESG adaptation, mitigation strategies for ESG implementation, and emerging opportunities in ESG evolution. The findings reveal a significant evolution from compliance-driven approaches toward strategic integration where sustainability creates shared value for stakeholders (Cornell & Shapiro, 2020; Zumente & Bistrova, 2021). Despite sophisticated implementation approaches, persistent barriers include data management challenges (fragmented data, varying formats, manual processes) and supply chain control issues. Successful firms deploy technological solutions (AI, blockchain, enterprise systems), systematic stakeholder engagement, and capacity building mechanisms to overcome these challenges. This research makes several theoretical contributions by demonstrating how Indian firms adapt global ESG frameworks to local institutional contexts, revealing the differential impacts of individual ESG pillars on various performance dimensions through disaggregated analysis (addressing the aggregate score limitation identified by Dong et al., 2022), and identifying critical moderating and mediating mechanisms that influence the ESG-performance nexus. Methodologically, the study advances ESG research by employing a comprehensive 13-indicator performance framework spanning financial metrics (seven indicators), market measures (four indicators), and value-based metrics (two indicators), thereby addressing the narrow measurement approach prevalent in prior literature (Alshehhi et al., 2018; Rothaermel, 2017). The sequential mixed methods design provides both breadth through quantitative patterns and depth through qualitative implementation insights, responding to calls for methodological pluralism in ESG research (Malina et al., 2011; Leech & Onwuegbuzie, 2010). Practical implications include sector-specific implementation guidelines for corporate managers recognizing that optimal ESG strategies vary by industry context, evidence based insights for investors seeking sustainable portfolio construction that accounts for sectoral heterogeneity, and policy recommendations for regulatory standardization balancing uniformity with sectoral flexibility. The study's social impact extends beyond corporate boardrooms, as documented ESG integration in workforce wellbeing, community development, and inclusive growth initiatives suggests that sustainable business practices can create virtuous cycles where corporate profitability aligns with social welfare, contributing to India's broader sustainable development goals and potentially accelerating progress from its current 120th global ranking (Sultana, 2021). By providing comprehensive empirical evidence from India's emerging market context, this research fills a critical geographic gap in ESG literature while offering actionable insights for stakeholders navigating the complex landscape of sustainable business practices in developing economies.
