The Impact of Corporate Governance Mechanism On Environmental Sustainability in Nigeria: A Case Study of Access Bank Nigeria Plc

The study investigated the impact of corporate governance mechanisms on environmental sustainability in Nigeria: a case study of Access Bank Nigeria Plc. Specifically, the study examined the impact of audit quality on the renewable energy of Access Bank Nigeria Plc, determined the contribution of board size to its renewable energy, and investigated the role of board independence in its renewable energy. The study employed the ordinary leased square four functional form method as its analytical technique. At the end of the study, the study found that audit size is positive and statistically significant at the 5 per cent level with renewable energy. This implies that a rise in audit size or quality at Access Bank PLC will lead to an increase of about 17 per cent in the renewable energy policy of Access Bank PLC. Furthermore, the coefficient for board size and board independence indicates a negative, statistically insignificant relationship with the renewable energy program of Access Bank PLC. This implies that an increase in board size and board independence will result in decreases of about 29 per cent and 28 per cent, respectively, in Access Bank PLC's renewable energy policy. Based on the findings, the study recommended that regulators, corporate stakeholders, the banking sector, and multinational companies should focus on holistic audit size, board size, and board independence rather than on specific elements within these corporate governance mechanisms. All the elements under each of the corporate governance mechanisms operate interactively to secure good governance that meets the needs of all the corporate stakeholders. Also, consideration for board membership should not be based on share ownership, but rather on competence.
