We have established "HEALTH, SAFETY and ENVIRONMENTAL POLICY", ensuring that all employees understand and apply its principles in our work under the commitment of senior management.

• HEALTH, SAFETY and ENVIRONMENTAL POLICY

We have established and implemented an HSE (Health, Safety, and Environment) Management System, referencing international standards such as ISO 14001 and industry guidelines. This system clearly defines organizational structures, roles, and responsibilities, ensures compliance with relevant laws and regulations, and helps prevent incidents and environmental issues by assessing and mitigating risks in business activities. Furthermore, we regularly review the effectiveness of our HSE activities and promote continuous improvement in alignment with the PDCA (Plan-Do-Check-Act) cycle.

To prevent serious workplace incidents including fatalities, we adopted the “IOGP Life-Saving Rules” in 2025. These rules were established by the International Association of Oil & Gas Producers (IOGP) and are internationally recognized fundamental principles for ensuring safety. In addition to providing education and training for our employees, we promote the practical implementation of these rules at worksites by employees and, where applicable, in collaboration with contractors.

In accordance with the ENEOS Group’s Environmental Management System, we regularly monitor progress toward environmental targets and compliance with environmental laws and regulations. To contribute to building a sustainable society, we are committed to conserving natural resources—such as water, soil, and air—and protecting biodiversity, while ensuring proper waste management and promoting resource recycling.

HSE-related data, including health and safety performance and environmental information, is disclosed to the public through the "ESG DATA BOOK" published by ENEOS Holdings.
