The survey design was adopted in this study using a questionnaire that was administered to preparers and users of corporate reports. A combination of t-test and regression was used to test the hypotheses of the study. The findings confirm the low level of voluntary environmental disclosure mechanisms practiced in Nigeria. Finally, preparers are aware of the information need of users. In conclusion, the study shows that much priority is not given to environmental reports. It is recommended from this study that firms should ensure that the level of their EDQ is continuously improved to aid user decisions and secure a positive impression of stakeholders about the firms. Government and standard setters should gear efforts towards standardization of environmental disclosures of firms in Nigeria through legislation and issuance of standards to improve the quality of disclosures. Keywords: Corporate reporting, decision usefulness, environmental disclosure quality 1. Introduction Corporate reporting derives its essence from the relevance of information disclosed for decision-making, otherwise, it becomes meaningless, irrelevant and a waste of resources (Georgiou, Mantzari& Mundy, 2021). The International Accounting Standard Board (IASB) restored decision application as the main objective of the General Purpose Financial Statement (GPFS) in the revised conceptual framework for financial reporting, hereafter referred to as ‘the framework’ (IASB, 2018). The IASB describe International Financial Reporting Standards (IFRS) compliant financial statement as a decision support tool. 1 Department of Accounting, Finance and Taxation, Caleb University, Imota, Lagos, Nigeria 2 Department of Accounting, Finance and Taxation, Caleb University, Imota, Lagos, Nigeria 3 Department of Accounting, Finance and Taxation, Caleb University, Imota, Lagos, Nigeria
