Most oil and gas quoted companies in Nigeria have often given insufficient attention to the communities where they operate, this is usually because of the need to regularly increase their profit maximization strategy. This study focuses on the effect of Environmental Accounting and the Corporate Performance of Selected Quoted Companies in Nigeria. Ten (10) quoted oil companies were randomly selected from the Nigerian Stock Exchange. The secondary data used were from the audited financial statements of the Oil companies. Environmental accounting reporting was measured by environmental cost and disclosure. The corporate performance of the Oil companies was measured using return on capital employed (ROCE); net profit margin (NPM), Return on Equity (ROE) and Return on Assets (ROA). The data were analyzed using multiple regression analysis. The findings of the result show that there is significant positive relationship between environmental accounting and Return on Capital Employed (ROCE) and net profit margin (NPM), Return on Equity (ROE) and Return on Assets (ROA).Based on the findings, it is therefore recommended that government should make environmental disclosure compulsory and also impose sanctions on the violation by any Oil company in Nigeria; compliance by the Oil companies should be taken seriously so that the environment will be safe for economic growth and development. Government should give tax credit to organizations that comply with its environmental laws and that environmental reporting should be made compulsory in Nigeria so as to improve the performance of organizations and the nation as a whole.
