Governance and Oversight
The Company integrates air quality management and stakeholder well-being as part of its sustainable building design and management strategy. A specialized engineering team has been established to oversee air quality management, apply advanced technologies for air quality analysis, and drive continuous improvement. Under the supervision of the Climate and Environment Committee, these efforts ensure that the Company’s operations are aligned with green building standards and healthy building standards.
Challenges and Opportunities
The Company recognizes the escalating PM2.5 crisis, particularly during the beginning and end of the year, especially in Northern Thailand and Bangkok. PM2.5 is classified by the World Health Organization (WHO) as a Group 1 carcinogen. This issue represents not only an operational challenge in managing building air-conditioning systems, but also a business risk, as air pollution may influence customer behavior and discourage visits to shopping centers. This could, in turn, affect the revenue of shopping centers and tenants. Furthermore, effective air pollution management requires advanced green technologies, such as high-efficiency air filtration systems, which may involve relatively high upfront investment costs.
Nevertheless, innovation and green technology also present opportunities to transform this crisis into a competitive advantage. By investing in precise air quality control technologies, the Company can position shopping centers as trusted “Safe Haven” spaces for customers. This supports customer footfall, creates long-term value, and enhances attractiveness to ESG-focused investors. In addition, emerging integrated technologies can help manage indoor air quality while improving energy efficiency. The Company also recognizes the importance of building networks and collaboration with relevant agencies at local and national levels. Such collaboration helps strengthen air quality management and reinforce a positive corporate image.
Transparent and efficient implementation of projects and measures also helps build confidence among communities and investors.
Management Approach and Value Creation
Central Pattana Public Company Limited is committed to integrated air quality management across all stages of its operations, from strategic planning and business execution to performance evaluation and continuous process improvement. This approach is designed to ensure effective air quality management while aligning with the Company’s sustainability policy in all dimensions. The Company has also established a specialized team and deployed advanced analytical tools to continuously monitor, control, and improve air quality.
Furthermore, Central Pattana integrates Stakeholder Well-being into building environment design by encouraging tenants to follow the TREES-CS (Core & Shell) green building guidelines. The Company also establishes standards for air-conditioning systems and air filtration equipment in leased areas to support sustainability objectives and alignment with the WELL Building Standard for healthy buildings.
Risk Management and Guidelines
The Company has established integrated air quality management measures covering the construction period through to the operational phase, focusing on three main dimensions as follows:
Effective air quality management and sustainable economic and social value are created.
Pollution Control During Construction
- Block off the area with a Metal Sheet fence and install a panel to prevent falling materials and cover the canvas with dust protection at all times.
- Spray water to reduce the spread of dust and spray wash the wheels of the car before leaving the project.
- Requires the use of vacuum fans with filter bags in construction areas to protect the health of workers.
- Set standards for selecting low-volatile organic compound (Low VOC) paints and coating materials for new projects.
-
Include conditions in contractors' terms of reference (TOR) requiring daily dust-level measurements at construction sites and surrounding communities, including measurement, prevention, corrective action, and reporting requirements as follows:
- Measure daily, including total dust or particulate matter no larger than 100 microns (TSP), PM10, PM2.5.
- Measured on a monthly basis, including the gas levels of CO2, SO2, NO2, and total hydrocarbons (THC).
- Specified to prepare weekly and monthly results reports throughout the construction period. as well as hiring third-party experts to inspect and monthly report.
- Set targets for air quality within construction sites and surrounding areas to meet the standards prescribed by ministerial regulations and the 2026 announcement of the National Environment Board, as announced in the Royal Gazette in early 2026.
- Establish construction-site preventive measures by installing portable 32-inch water mist sprayers in every project.
Building Engineering and Technology Standards
- Install air filters according to MERV 8 and MERV14 standards (during periods of high PM2.5 levels) at outside air conditioners (OAUs) and large cold air units (AHUs). Piloted in 12 projects in high-risk areas in the northern region.
- Install a 24-hour automatic air quality sensor system (IAQ Sensors) to monitor PM2.5 values if critical outside air quality is found. The system will automatically turn off or reduce the amount of aeration air.
- Piloting the use of HVAC Air Scrubber technology at Central Ayutthaya to reduce heat conduction into the building. Along with reducing dust, absorbing toxins and capturing carbon dioxide (CO2) and VOCs at the same time.
Collaborative Network Management
- Tenant: Set air system standards and air filtration equipment in the rental area to be in line with green building standards (TREES-CS).
- Government agencies and partners: Collaborate with Bangkok Metropolitan Administration on the "This Car #Reduces Dust" campaign, offering two hours of free parking at eight branches for customers who show oil-change receipts, helping reduce sources of urban dust.
-
Customer:
- Install electric vehicle (EV) charging stations to support the adoption of clean energy technology.
- Request cooperation from parking users by refraining from leaving vehicle engines idling in the parking area. Security personnel patrol the parking lot to monitor compliance.
-
Employees:
- Regularly inspect company vehicles and company document-delivery vehicles to ensure they are in good condition and do not emit excessive pollution. Encourage employees to inspect and maintain their personal cars and motorcycles as well.
- Promote online meetings to reduce travel and the resulting air pollution.
