The focus of this research is on companies engaged in the energy sector and have been listed on the Indonesia Stock Exchange (IDX) during the period 2023 to 2024. The sample selection was carried out using purposive sampling technique based on certain criteria, so that 75 companies were obtained that met the requirements with a total of 150 data observations for two years of observation. Data analysis was carried out using a quantitative approach with the Moderated Regression Analysis (MRA) method to identify direct effects and effects moderated by the presence of Green CEO. The results of the analysis show that directly, ESG performance does not have a significant influence on the company's financial performance. However, the presence of Green CEO proved to be able to moderate the relationship between ESG performance and financial performance, thus indicating that environmentally oriented leadership can strengthen the contribution of ESG in improving the company's financial performance. This finding provides important implications for companies in considering sustainable leadership aspects as a performance improvement strategy.
