The Company is committed to conducting its business through the efficient and sustainable utilization of resources, as well as promoting the efficient and sustainable use of resource within the organization and office buildings. These efforts support the Company’s mission and greenhouse gas emission reduction targets, in alignment with international environmental criteria and standards. Consequently, the Company has established the revised Environmental Policy for Building Management, with the key principles outlined as follows:

Regular monitoring and compliance audits shall be conducted, and environmental management practices within office buildings shall be continuously reviewed and improved.

2. Commitment to Supporting the Organization's Greenhouse Gas Emission Reduction Targets

The Company is committed to supporting its greenhouse gas emission reduction targets by reducing operational emissions in office buildings (Scope 1 and Scope 2) by at least 30% by 2035. This will be achieved through improving energy efficiency, systematically managing electricity and fuel consumption, utilizing renewable energy, and enhancing technologies and operational practices. In addition, the Company shall ensure proper refrigerant management, with emphasis on leakage prevention and preventive maintenance. Progress shall be monitored, evaluated, and reported annually to ensure alignment with the Company’s Pathway to Net Zero and long-term sustainability objectives.

3. Energy Management in Office Buildings

The Company focuses on the efficient and continuous use of electricity, with a target to reduce electricity consumption in its buildings by at least 40% by 2035 compared to the baseline year. This objective shall be achieved through improving the efficiency of air-conditioning and building services systems, deploying digital technologies and automation systems, investing in renewable energy for self-consumption, and promoting energy-efficient practices across all business units.

4. Efficient Water Management

The Company shall promote water efficiency through the use of water-saving devices and the regular maintenance of related equipment. It shall monitor water consumption within its buildings, encourage water reuse where appropriate, and continuously promote water conservation practices.

5. Waste Reduction and Waste Management

The Company shall implement a systematic waste segregation program within its office buildings and apply the 7R principles to promote waste management, including reuse, recycling, and end-of-life waste disposal. The Company shall also minimize paper consumption and the use of single-use plastics, while promoting Zero Waste practices across various corporate activities.

6. Prohibition on the Use of Foam Food Containers

The Company is committed to enhancing environmental safety and reducing microplastic pollution. Therefore, the use of all types of foam containers and packaging (EPS/Styrofoam) is strictly prohibited within the organization. This measure shall apply to all areas within the Company's buildings, including leased retail spaces, common areas, and corporate activities. Compliance is required from all personnel, visitors, contractors, and external service providers. The Company encourages the use of environmentally friendly alternatives, such as plant-fiber products, food-grade paper packaging, PLA/PP containers, and reusable containers. To ensure compliance, the Company will establish monitoring, inspection, and compliance reporting measures, along with warning procedures for any violations of this policy. If any foam containers or packaging are brought into or found within the building, the responsible party shall be required to remove such items from the premises immediately. Building management personnel reserve the right to issue warnings, prohibit their use, and require the immediate removal from the premises. Such items shall not be left or disposed of within the building.

7. Indoor Air Quality Management

The Company focuses on controlling volatile organic compounds (VOCs) emitted from paints, materials, and equipment used within its office. The Company shall regularly monitor indoor air quality parameters as required by applicable laws and Environmental Impact Assessment (EIA) requirements, including PM2.5 concentrations within the building. The Company shall provide adequate ventilation systems, strictly prohibit smoking within the building and designated non-smoking areas, and regularly report indoor air quality monitoring results.

8. Green Procurement

The Company shall consider the procurement of environmentally friendly products and services, such as Green Label products, biodegradable paper or paper containing recycled materials, as well as products and services that support long-term reductions in energy consumption or waste and establishing environmental criteria as part of procurement conditions.

9. Environmental Communication and Awareness

The Company shall promote environmental awareness and encourage cooperation among employees and building occupants in reducing resource consumption. The Company shall organize training programs and awareness-building activities to foster environmental responsibility and sustainability consciousness, and shall regularly disclose environmental information to employees and stakeholders. In addition, communication channels shall be established to receive feedback, suggestions, and complaints from employees, supporting the continuous development and improvement of environmental management practices throughout the organization.

10. Monitoring, Reporting, and Policy Review

The Company, through the General Administration Department, shall be primarily responsible for implementing this policy. This includes developing environmental key performance indicators (KPIs), such as reductions in energy consumption, water consumption, waste generation, and greenhouse gas emissions. Progress shall be regularly monitored, reported, and disclosed to management. The policy shall be reviewed annually to ensure its continued alignment with applicable laws, regulations, standards, and relevant technologies.

The Company recognizes that the environmental management within its office buildings is essential to creating a workplace that promotes the well-being and quality of life of all occupants. Environmental stewardship is therefore regarded as a shared responsibility of employees at all levels, who are expected to actively support and comply with this Office Building Environmental Management Policy. Through the collective commitment and participation of all stakeholders, the Company aims to strengthen its position as a green organization and achieve sustainable growth in line with its long-term sustainability objectives.
