Does ISO 14001 Boost Energy Firm's Financial Performance? The Moderating Role of Environmental, Social, and Governance

ABSTRACT This study examines the financial consequences of ISO 1400 stices. Based on a large international dataset and advanced econometric methods, the analysis reveals that ISO 14001 adoption is positively linked to financial performance. The effect is amplified when firms demonstrate stronger ESG engagement, with environmental, social, and governance pillars each contributing to improved outcomes. Interaction results indicate that certification combined with ESG practices yields the most substantial gains, particularly for smaller firms and those operating in weaker institutional environments. These findings highlight the strategic importance of aligning environmental certification with ESG initiatives to enhance competitiveness, satisfy stakeholder expectations, and promote sustainable transitions. The study provides actionable implications for managers, policymakers, and investors seeking to integrate environmental management with responsible corporate governance.
