The study assessed the effect of Environmental Accounting Information Disclosures on Financial Performance of Cement Manufacturing Companies in Nigeria from 2006 - 2020. Ex-post facto research design was adopted in carrying out the study. Secondary data were gathered from the annual reports of listed cement companies on the Nigeria Stock Exchange (NSE) to actualize the research objectives stated for the research work. The panel data gathered were analytically estimated using the Multiple Ordinary Least Square (MOLS) regression techniques with the aid of E-view 9.0 econometric software to test the hypotheses and establish the effect of environmental accounting information disclosures on corporate profit performance. The study revealed that corporate social responsibility disclosure, health and safety disclosure and remediation/pollution control disclosures have significant effects on return on assets of listed cement companies in Nigeria. The study concluded that disclosures of Environmental Activities in the annual reports of companies have effect on their financial performance. It was recommended that companies should ensure sustainability reporting in their annual reports; government should liaise with both national and international accounting standard setting bodies to ensure that environmental disclosures are mandatory.
