Environmental Quality Management

Environmental Management Principles

The Company has defined four key environmental management principles:

To strengthen environmental management, the Company has adopted an Environmental Policy and developed an Environmental Management Manual as a framework for responsible operations, covering efficient resource use, pollution impact reduction, and strict compliance with relevant environmental laws and requirements. The Company has also appointed an Environmental Working Group to drive organizational environmental management, coordinate activities, and monitor performance against defined targets. The key responsibilities of the Environmental Working Group include:

• Identifying and assessing environmental and energy issues arising from the Company’s activities.
• Reviewing and updating the legal and requirements register.
• Assessing compliance with relevant laws, regulations, and requirements.
• Developing environmental systems and operational procedures in accordance with Environmental
• Procedures (EP).

The Company places strong emphasis on responsible and sustainable industrial area development, supporting the government’s Eco Industrial Town policy as a guideline for environmental, social, and economic management within its industrial parks. The framework covers 5 dimensions and 20 aspects, encompassing the Physical, Economic, Social, Environmental, Community, and Management dimensions. Adopting the Eco Industrial Town framework enables the Company to maximize industrial area management efficiency, environmental friendliness, community benefit, and balanced economic growth.

management to enhance operational efficiency, reduce environmental impacts, and support efficient energy use. The following international standards are applied as operational frameworks:

• ISO 9001:2015 Quality Management System
• ISO 14001:2015 Environmental Management System
• ISO 50001:2018 Energy Management System

3 Saha Group Industrial Parks have received ISO 14001:2015 Environmental Management System certification, representing 37.5 percent of all parks.

Environmental quality monitoring results from the previous year indicate that all indicators were within legally defined standard thresholds — reflecting the success of the Company’s preventive measures and proactive environmental management.

Environmental Complaint Management

The Company places strong emphasis on receiving feedback and complaints from employees and all stakeholder groups, providing diverse and easily accessible complaint channels covering human rights, legal compliance, and regulatory matters. Received complaints are processed by a designated committee under strict confidentiality, within defined timeframes, transparently and fairly, with results reported to management for use in management system development and organizational governance enhancement. Complaint channels and complaint management measures are detailed in Section 1.6.7: Complaint Reception and Management.

The Company places strong emphasis on social and environmental complaints, adhering to principles of transparency, stakeholder participation, and strict legal compliance, conducting systematic root cause investigation and analysis, and defining preventive approaches to ensure effective and sustainable problem resolution. The complaint management process is divided into 2 levels:

1. Initial Consultation and Problem Resolution: When a complaint arises within an operating area, the Company dispatches relevant officers or departments to inspect the affected area and provide improvement recommendations, corrective approaches, and appropriate management — including coordination with external specialists or government agencies where necessary — to concretely elevate corrective measures.
2. Coordination through Regulatory Agencies: If a complaint issue persists or is complex in nature, the Company submits a formal complaint to regulatory agencies such as the Provincial Natural Resources and Environment Office (PONRE) or the Department of Industrial Works (DIW) to jointly inspect and identify corrective measures with government agencies — to ensure resolution addresses root causes and prevents recurrence in the future.
