<![CDATA[The growing emphasis on environmental sustainability has encouraged companies in developing economies, including Indonesia, to adopt more transparent and responsible business practices. Despite regulatory support through Financial Services Authority Regulation No. 51/POJK.03/2017 on Sustainable Finance, empirical evidence on how Green Accounting and Environmental, Social, and Governance (ESG) reporting influence corporate outcomes remains limited, particularly among manufacturing firms that simultaneously drive economic growth and generate substantial environmental impacts. This study aims to address this research gap by examining the direct and indirect effects of Green Accounting and ESG reporting on company performance. Using a quantitative explanatory approach, the study analyzes secondary data from annual reports, sustainability reports, and financial statements of manufacturing firms listed on the Indonesia Stock Exchange for 2018–2023. Green Accounting is measured through environmental cost disclosures and environmental management reporting, while ESG reporting is assessed using disclosure indices and third-party ESG scores. Market reputation is operationalized through awards, media sentiment, and industry rankings, and profitability through ROA and ROE. Panel data regression and SEM-PLS are employed to test direct and mediating effects. The findings indicate that Green Accounting and ESG reporting positively influence market reputation. Market reputation, in turn, enhances profitability and mediates the relationship between sustainability initiatives and financial performance. Overall, the study highlights sustainability as both an ethical imperative and a strategic driver of competitive advantage for Indonesian manufacturing firms.]]>
