The company aims to mitigate and prevent environmental impacts throughout the value chain by maximizing the benefit of natural resources using, in line with the principles of the Bio-Circular-Green Economy, while adhering to waste and pollution control regulations that may affect the environment. OR also applies an Environmental Management System (ISO 14001) across OR’s establishments, all of which have been certified in accordance with ISO 14001 by external certification bodies.
            OR sets annual environmental performance targets that align with the corporate goal or OR 2030 Goals under the Healthy Environment dimension. This target has the objective to create a sustainable environment by increasing renewable energy, reducing greenhouse gas emissions, and decreasing waste generated from business operations by more than one-third compared to the year 2022. This includes the implementation of the Quality, Safety, Health, and Environment Management System.
            In 2024–2025, OR developed the OR ESG Data Platform, a sustainability data management system covering environmental, social, and governance dimensions, to drive the centralization of OR’s sustainability data collection. The platform incorporates a multi-level data approval process by supervisors at various levels to ensure that environmental, social, and governance data are accurate, transparent, and traceable (Data Governance).
            In addition, Quality, Security, Health, Safety, and Environment targets (QSHE Targets) have been established to control and reduce environmental impacts across OR’s establishments in both the oil business and the retail business. The Sustainability, Quality, Safety, Health and Environment Department monitors environmental performance and utilizes the data for analysis to further enhance OR’s environmental management processes.
            In addition, OR has established and developed standards for PTT Station (Service Station Standard) and LPG filling plants, which include environmental management requirements such as waste management and wastewater management. These standards are communicated to customers and PTT Station dealers, as well as LPG filling plants. Furthermore, there is regular inspection and evaluation of the environmental operations of PTT Stations managed by OR.
OR has established a policy to promote education and training of employees and raise awareness on the environment following the QSHE Policy. OR conducted overall training courses in environmental management as shown in the following:

1. 1. 1. Basic Environment for Employee, delivered in an e-learning format, enables all OR employees to undertake the training independently through the OR LMS. The program aims to provide employees with fundamental knowledge of environmental management in establishments.

      3. The “Data Internal Verification” training program, conducted by experts in accordance with the Global Reporting Initiative (GRI) disclosure framework, aims to equip participants with an understanding of organizational environmental data collection, consolidation, and reporting processes, as well as basic methods for verifying data accuracy. This is to ensure that reported data is accurate prior to verification by independent assurance providers and subsequent public disclosure.
      4. Training on the use of the OR ESG Data Platform is provided to ensure that employees responsible for recording OR’s sustainability data understand the data collection requirements for each indicator, be able to analyze data, and can record information accurately and comprehensively in line with internationally recognized reporting standards.
