Inserting Environmental, Social, Governance (ESG) Principles into Pension Fund Investments in Nigeria: Implications for Risk Management, Returns, And Sustainable Growth

This study assessed the outcome of inserting Environmental, Social, Governance (ESG) principles into pension fund investments in Nigeria, focusing on the interchange between risk management, financial performance and sustainable economic growth. Relying on panel data from Nigerian Pension Fund Administrators (PFAs), the study employed various analytical and data diagnostic methods including pooled Ordinary Least Squares (OLS), Fixed Effects (FE), Random Effects (RE), and System Generalized Method of Moments (GMM) estimators. Also, the study used Sharpe ratio to gauge risk-adjusted performance and breaks down ESG integration into components into climate risk exposure, governance quality, infrastructure investment, and ESG screening mechanisms. The results show that integrating ESG principles has on general note significantly boost pension fund performance, mainly by enhancing risk-adjusted returns and lowering exposure to environmental and governance risks. Specifically, Climate risk exposure tends to limit performance, governance quality stands out as the most significant positive factor. Sustainable infrastructure investment also plays an enhancing role, albeit modestly, reflecting its long-term return potential. The study therefore recommends, amongst others that policymakers should focus on strengthening ESG regulatory frameworks, inject accurate disclosure standards, and as well encourage pension fund managers to invest in sustainable infrastructure projects.
