A Professional Examination of Environmental Social Governance Disclosure Obligations for Nigerian Listed Companies

Environmental social governance disclosure is increasingly demanded by investors, regulators, and civil society, and the Nigerian Exchange Group Sustainability Disclosure Guidelines 2023 alongside Securities and Exchange Commission ESG reporting requirements represent the most significant expansion of corporate reporting obligations in a generation. This study provides a professional examination of ESG disclosure obligations applicable to NGX-listed companies, the enforcement mechanisms available to the SEC and NGX, and the current state of ESG compliance across the listed company universe. Data were collected through analysis of sustainability reports published by 30 listed companies from 2021 to 2023, supplemented by interviews with 15 sustainability and governance professionals. Results indicate that environmental disclosure quality is the weakest ESG dimension, with fewer than 20 percent of companies reporting against quantifiable environmental metrics. Social disclosure is strongest, driven by existing CSR reporting traditions. Governance disclosure has improved following the Nigerian Code of Corporate Governance 2018. The study concludes that ESG disclosure in Nigeria is improving but remains largely narrative and unverifiable. Recommendations include mandatory third-party assurance for ESG reports of all NGX Premium Board companies, standardised ESG disclosure templates aligned with the International Sustainability Standards Board framework, and SEC enforcement action for material ESG misstatements.
