Purpose – This study aims to examine the effect of environmental performance and Corporate Social Responsibility (CSR) disclosure on the financial performance of mining companies listed on the Indonesia Stock Exchange (IDX) during the 2022–2023 period. Design/Methodology/Approach – This study adopts a quantitative approach using secondary data obtained from annual reports, sustainability reports, and PROPER documents of listed mining companies. Environmental performance was measured using the PROPER rating issued by the Ministry of Environment and Forestry (KLHK), CSR was measured based on the GRI Standards 2021 disclosure items, and financial performance was assessed using Return on Assets (ROA). Data were analyzed using multiple linear regression analysis. Findings – Environmental performance has a positive and significant effect on financial performance, whereas CSR disclosure has no impact on financial performance. These findings indicate that compliance with environmental standards can enhance financial outcomes, but CSR disclosure alone is insufficient to generate direct financial benefits. Originality/Value – This study provides empirical evidence on how sustainability initiatives specifically impact the financial performance of high-environmental-risk mining companies in Indonesia, emphasizing the necessity for firms to focus on substantive environmental compliance and integrate sustainability into their core business strategies.
