Sustainability Assurance​

Sustainability assurance is a crucial process that enhances the credibility, reliability, and transparency of Banpu’s sustainability practices. It involves the evaluation of our sustainability processes, data, and disclosures to ensure that the information presented is accurate, comprehensive, and aligned with recognized international standards and frameworks. This assurance process not only helps build trust with stakeholders but also supports Banpu in achieving our long-term sustainability goals.

Three Lines Model in Sustainability Management

Banpu adopts the three lines model, a widely recognized risk management framework in managing sustainability-related risks. This approach helps ensure effective governance, accountability, and continuous improvement across all levels of sustainability management.

First Line: Operations
Business units are responsible for the day-to-day management of sustainability-related topics within their respective areas. This includes identifying sustainability-related risks and opportunities, ensuring compliance with internal policies and external regulations, and integrating ESG considerations into business operations.

Second Line: Corporate Office
Specialized functions at the Corporate Office provide oversight and support to the first line. This includes establishing sustainability-related policies, offering training and capacity-building, and facilitating communication between strategic oversight and operational execution. The second line ensures that sustainability-related policies, standards, and targets are effectively communicated and implemented across the organization.

Third Line: Sustainability Assurance
Sustainability Assurance Department conducts quality assurance reviews (QARs) to evaluate the effectiveness of sustainability management and control processes. This function independently assesses the adequacy and effectiveness of both the first and second lines through audits, process reviews, and recommendations for improvements.

In addition to internal assurance, Banpu engages independent third-party auditors to conduct external assurance. These auditors assess sustainability data and disclosures in accordance with internationally recognized standards, further enhancing the credibility and transparency of Banpu’s sustainability performance disclosed to the public.

Sustainability Process Assurance

Sustainability process assurance focuses on evaluating the effectiveness and consistency of our sustainability management processes
• Internal Assurance: Conducted annually by the Sustainability Assurance Department and relevant internal functions to ensure alignment with policies, standards, and procedures established by the Corporate Office.
• External Assurance: Performed by third-party auditors following international standards such as ISO, AA1000, and GRI to validate that processes meet recognized benchmarks.

Sustainability Data Assurance

Sustainability data assurance focuses on verifying the accuracy, completeness, and reliability of the data disclosed to stakeholders.
• Internal Assurance: Conducted annually by the Sustainability Assurance Department to ensure that data is collected and reported in line with both GRI Standards and internal controls.
• External Assurance: Overseen by the Corporate Sustainability Function, which engages independent third-party assurance providers to verify the data disclosed in the sustainability report regarding its compliance with GRI Standards.

Sustainability assurance supports the robustness of governance, internal controls, and data processes related to sustainability‑related information disclosed by the Company, helping enhance the reliability and consistency of information prepared for inclusion in our sustainability report. This also supports the ongoing enhancement of sustainability‑related governance and data processes through periodic reviews and feedback.
