DOES BOARD ENVIRONMENTAL EXPERTISE LEAD TO ESG PERFORMANCE IN NIGERIA?

This study examines the relationship between board environmental expertise and environmental, social, and governance (ESG) performance among publicly listed firms in Nigeria. Drawing on resource dependence theory and upper echelons theory, we analyze panel data from 148 Nigerian listed firms spanning 2010-2024. Using fixed effects panel regression models, our findings reveal a significant positive relationship between board environmental expertise and ESG performance, suggesting that directors with environmental knowledge, qualifications, and experience enhance corporate sustainability outcomes. The results remain robust after controlling for firm size, profitability, leverage, growth opportunities, industry type, and firm age. This study contributes to the emerging literature on board composition and ESG performance in developing economies, particularly in the African context, where empirical evidence remains scarce. The findings have important implications for corporate governance reforms, regulatory frameworks, and sustainability practices in emerging markets.
