The analysis of the US S&P 500 index is among numerous global studies that demonstrate a correlation between ESG performance and corporate value and profitability. There remains a lack of literature addressing the oil and gas sector in developing nations such as Indonesia. This research is essential for understanding the impact of ESG on the value and profitability of companies within the energy sector of the country. This research will analyse the ESG Scores, revenue, and firm value of companies operating in carbon-intensive sectors. A data-panel regression is employed methodically for the analysis. The group comprises 18 companies listed on the Indonesia Stock Exchange (IDX). The companies operate within the coal mining and oil and gas subsectors, with data spanning the years 2021 to 2023. Financial performance is measured by the profitability ratio, while Firm Value is measured using market-based indicators. This research employs a data-panel regression model to examine the relationships among these variables. This study examines the hypothesis that ESG Score positively influences the financial performance and valuation of companies. The findings indicate that ESG scores exert insignificant influence on firms' earnings or value (Tobin's Q). Both were examined.
