Climate change is compelling companies—particularly those in the mining sector—to enhance their disclosure of sustainability information and climate-related risks. This study aims to describe the sustainability and climate-related risk disclosures of PT Bukit Asam Tbk (PTBA) for the 2022–2025 period. A qualitative descriptive method was employed, utilizing content analysis of PTBA’s sustainability reports from 2022 to 2025. Disclosures were assessed using 20 indicators covering climate risks, greenhouse gas emissions, energy, decarbonization, environmental aspects, and independent assurance. The findings indicate a disclosure completeness rate of 95% in 2022, which increased to 100% for the 2022–2025 period. A notable difference was observed regarding the disclosure of transition risks; these were not explicitly identified in 2022 based on the study’s criteria, whereas they were disclosed more clearly in subsequent periods. These results demonstrate that PTBA consistently discloses sustainability information and climate-related risks in its sustainability reports. However, the level of disclosure completeness does not necessarily reflect the quality or effectiveness of the disclosures themselves.
