Many companies in Indonesia use natural resources, both ocean and land products, as raw materials for the company's production. Currently in Indonesia, disclosure of environmental accounting has not been specifically regulated in accounting standards, meaning that the reporting of environmental information in the company's annual report is still voluntary. If there are companies that have not reported environmental costs, there is no specific policy from the government, even though company waste can damage the surrounding environment if it is not managed properly.The purpose of this research is to know the environmental costs and financial performance in the perspective of Islamic economics. Quantitative methods are used in this study and use Smart PLS 3.0. The results showed that there was an effect of environmental costs on the financial performance of ROA, ROE, and NPM.
