Topics related to environmental, social, and governance are currently interesting to research because the importance of sustainability principles in the business world is increasingly recognized. This research investigates the influence of the ESG pillar and state ownership on the cost of debt in non-financial companies. The analysis was carried out on public companies in emerging Asian countries during the period 2016 to 2023 using panel data regression. Using various theories such as agency theory, stakeholder theory, and signaling theory, this research proves that state-owned companies with better ESG scores have lower debt costs. An unexpected finding is that the social pillar has a positive effect on the cost of debt. For the environmental pillar, although it is negatively related to the cost of debt, the effect is not significant. Meanwhile, the governance pillar has a significant negative influence on the cost of debt in accordance with agency theory. It is hoped that the results of this research will contribute to providing insight to stakeholders, especially managers and company owners, regarding the role of ESG and state ownership in the magnitude of corporate debt costs
