While ESG has become central to sustainable business strategies, empirical evidence on the role of governance-related mechanisms remains mixed, particularly in emerging markets. Background Problems: Global concerns over accountability and stakeholder trust have increased the demand for credible ESG practices. Investors, regulators, and the public seek not only disclosure but also assurance of its reliability. Yet, in many emerging economies, the effectiveness of governance structures in driving ESG outcomes is still debated. Novelty: This study provides one of the first empirical examinations in Indonesia that positions sustainable assurance as an independent determinant of ESG performance. It contributes new evidence to global debates on ESG accountability by showing the transformative role of assurance beyond traditional governance attributes. Research Methods: A quantitative design with panel data regression was applied to firms listed in the ESG Leaders Index from 2020-2024. This dataset captures companies recognized for sustainability commitment and allows robust testing of governance attributes and ESG performance. Findings/Results: Results show that sustainable assurance has a significant positive effect on ESG performance, confirming its role as a credible mechanism for enhancing transparency, accountability, and legitimacy. Conversely, ownership concentration and gender diversity demonstrate no significant effects, suggesting that symbolic structural attributes may be insufficient to improve ESG outcomes in emerging markets. Conclusion: Sustainable assurance emerges as a decisive driver of ESG performance, whereas ownership concentration and gender diversity alone are not. These findings extend governance literature by emphasizing that assurance mechanisms, rather than structural attributes, shape credible ESG outcomes. Implementation Potential: Embedding sustainable assurance into corporate governance frameworks strengthens disclosure reliability, fosters investor confidence, and supports alignment with sustainable development goals, thereby enhancing long-term corporate resilience. Keywords: Board Gender Diversity; Ownership Structure; Sustainability Assurance; ESG Performance. JEL Classification: (list the relevant JEL codes separated by commas, refer to https://www.aeaweb.org/jel/guide/jel.php)},
