IMPACT OF ENVIRONMENTAL, SOCIAL, AND GOVERNANCE PRACTICES ON THE SUSTAINABLE PERFORMANCE OF TIER-1 NIGERIAN COMMERCIAL BANKS

Abstract

Environmental, Social, and Governance (ESG) practices have emerged as determinants of organisational sustainability within the banking sector. However, its adoption and implementation among Tier-1 Nigerian commercial banks remain uneven. Consequently, this study examined the impact of Environmental, Social, and Governance practices on the sustainable performance of Tier-1 Nigerian commercial banks. The study was guided by three specific objectives: to assess the effect of environmental practices on sustainable performance, evaluate the role of social practices in enhancing sustainable performance, and investigate the contribution of governance practices to sustainability outcomes. The research adopted a quantitative explanatory approach using secondary data obtained from the annual reports, sustainability reports, and published financial statements of selected Tier-1 Nigerian commercial banks between 2010 and 2024. Environmental practices were measured through indicators such as green banking initiatives, renewable energy adoption, etc; social practices were assessed through corporate social responsibility activities and employee welfare initiatives; while governance practices were evaluated using board independence, gender diversity, etc. Sustainable performance was measured using both financial indicators and non-financial indicators. Findings revealed that social initiatives received greater attention than environmental and governance dimensions. The study further established that balanced integration of all three ESG dimensions produces superior sustainability outcomes compared to isolated implementation of individual components. The study concludes that ESG practices constitute a strategic mechanism for achieving sustainable performance within the Nigerian banking sector. It recommends stronger regulatory enforcement and increased investment in environmental initiatives. The study contributes to the growing body of literature on ESG in emerging markets.
