This study explores the complex relationship between Environmental issues and Corporate Financial Reporting. It delves into the challenges companies encounter in quantifying and disclosing their environmental impact within financial statements. Regulatory requirements, stakeholder demands, and the evolving landscape of sustainable finance shape this discourse. It also seeks to examine the current state of environmental issues in corporate financial reporting in Nigeria and will explore the extent to which Nigerian companies disclose information about their environmental performance and impacts in their financial reports, the challenges they encounter in doing so, and the implications for stakeholders. Additionally, the paper will assess the effectiveness of existing regulatory frameworks and international reporting standards in promoting environmental transparency and accountability among Nigerian companies.
