Understanding the Impact of ESG Practices in Corporate Finance

This study examines the relationship between environmental, social, and governance (ESG) factors and corporate financial performance. Specifically, we study various individual ESG categories, both ESG strengths and concerns, and aggregate ESG factor and their impact on corporate financial performance including profitability and financial risk. We find a positive effect of ESG factors on corporate profitability, and the effect is more pronounced for larger firms. Among different ESG categories, corporate governance has the most significant impact, particularly for firms with weak governance. We also find that ESG variables generally have a positive influence on credit rating. In particular, the social factor has the most significant impact on credit rating, while environmental score surprisingly has a negative effect. Overall, this research provides a rationale for ESG integration in the context of investment management and portfolio construction to maximize value and minimize risk.
