To strengthen the ESG framework and enhance the quality of environmental information disclosure, CGPC participated in
the group-level greenhouse gas (GHG) assurance process on June 11, 2025. The process was conducted by Ernst & Young
Certified Public Accountants and coordinated by the Group ESG Division.
The assurance work covered Scope 1 and Scope 2 emissions generated from the company’s production and operations.
Through document review, on-site inspection, and data verification, the audit assessed the completeness and
consistency of GHG data and internal control mechanisms to ensure the credibility and verifiability of the information
provided.
Based on the assurance results, the company will further optimize its carbon management mechanisms and strengthen its
sustainable operational capabilities.
