Goal and Performance Highlights

Goal

by 2026 compared with the 2023 baseline year.

No

incidents of non-compliance with environmental regulations relating to air emissions, noise, or vibration were identified.

No

environmental fines, penalties, or sanctions related to air quality management were imposed during the reporting year.

Air Emissions Performance

Air Pollutant	Unit	2023 (Baseline Year)	2024	2025	Change from Baseline Year
NOX (Nitrogen Oxides)	Tonne	0.29	0.24	0.22	-24.1%
SOX (Sulfur Oxides)	Tonne	0.03	0.02	0.02	-33.3%
VOC (Volatile Organic Compounds)	Kg	170	178	185	+9.2%

Note: NOx, SOx, and VOC emissions were calculated based on fuel consumption from Company-owned vehicles, categorized by gasoline and diesel fuel use. Emission factors were derived from the IPCC 2006 Guidelines for National Greenhouse Gas Inventories, Volume 2, Chapter 3, Table 3.3.2, which are consistent with the methodology outlined in the EMEP/EEA Air Pollutant Emission Inventory Guidebook 2023. The reporting boundary excludes air

Commitment, Challenge and Opportunity

The Company places strong emphasis on managing air quality, noise, and vibration both within construction sites and in surrounding communities. Regular monitoring and assessment are conducted to ensure compliance with established standards, while continuous improvements to environmental control systems are implemented. These efforts aim to ensure legal compliance and strengthen stakeholder confidence in the Company’s operations.

Air and noise quality control at construction sites continues to face challenges arising from ever-changing environmental conditions, limitations of available technologies and the high costs of equipment, as well as increasing expectations from communities and stakeholders. In response, the Company must implement stringent measures and continuously improve its management practices.

Enhancing air and noise quality management standards not only mitigates environmental risks but also represents a key opportunity to strengthen the Company’s reputation for social responsibility, build greater stakeholder confidence, and create a competitive advantage in developing environmentally friendly real estate projects.

Management and Operational Approach

The Company has established a systematic approach to managing air emissions, noise, and vibration impacts across its construction projects. The approach encompasses environmental monitoring, preventive and mitigation measures, and continuous improvement initiatives to ensure compliance with applicable standards and minimize potential impacts on surrounding communities.

Monitoring and Performance Assessment

The Company conducts regular environmental monitoring covering key air quality parameters, including Total Suspended Particulates (TSP), PM10, PM2.5, nitrogen dioxide (NO₂), and sulfur dioxide (SO₂). Noise and vibration levels are also monitored to ensure compliance with regulatory requirements. Monitoring results are documented and reported through the Environmental Impact Assessment (EIA) Monitoring Report on a regular basis.

Control and Prevention Measures

To minimize air emissions and noise impacts, the Company implements a range of preventive measures. These include water spraying and covering construction materials with tarpaulins to suppress dust generation, scheduling construction activities appropriately to reduce noise disturbances, installing temporary noise barriers around major noise sources, and utilizing equipment and technologies designed to minimize vibration impacts. In addition, construction machinery and equipment are regularly inspected and maintained to ensure efficient operation and reduce emissions from operational sources.

Employee and Contractor Practices

Employees and contractors working at construction sites are required to strictly comply with dust, noise, and vibration control measures. Appropriate personal protective equipment (PPE) must be worn where necessary, construction materials and waste must be managed properly to prevent dust dispersion, and any abnormal environmental incidents must be reported immediately to supervisors. Employees and contractors are also encouraged to participate in environmental awareness campaigns and relevant training programs on an ongoing basis.

The Company continuously reviews monitoring results and performance data to improve its environmental control measures. In addition, the Company actively evaluates and adopts new technologies and best practices to enhance the effectiveness of air emissions, noise, and vibration management, thereby strengthening overall environmental performance across its operations.
