Ms. Uthaiwan Anuchitanukul, Head of Excellence & Sustainable Development of Central Pattana Plc., said: "Central Pattana believes that 'clean air is a fundamental right for all.' Guided by our vision, Imagining better futures for all, we are committed to enhancing quality of life across all dimensionsenvironment, health, and inclusive community growth. In Northern Thailand, where PM2.5 pollution remains a persistent challenge, we have established a regional sustainability task force to drive systematic solutions. Our holistic framework spans three dimensionsupstream, midstream, and downstreamreflecting a collaborative approach that engages all sectors in addressing PM2.5. This integrated effort aims to deliver sustainable, long-term impact.

Upstream - Central Pattana aims to plant 500-1,000 rai of forest annually between 2022 - 2032, or until reaching a total of one million trees, through the "One Million Trees Movement" initiative. The program seeks to offset greenhouse gas emissions and enhance carbon absorption, with over 40% already achieved to date. In parallel, the company is advancing a "Zero Burning" approach under the Central Tham initiative, working closely with local communities, farmers, and authorities to reduce open burning and sustainably address PM2.5 pollution at its source.

Midstream - Central Pattana is strengthening air quality management measures across its shopping centers and construction projects nationwide. Continuous efforts have been made to enhance indoor air quality, developing "Safe Indoor Spaces" to ensure a clean and safe environment. Measures include installing high-efficiency air filtration systems (HEPA filters) to reduce particulate matter and improve air circulation, implementing water curtain and misting systems to capture dust, and maintaining positive air pressure within buildings. Smart IoT-based monitoring systems have also been deployed to track PM2.5 levels in real time.

Downstream - Central Pattana is advancing support for vulnerable groups through the "Fresh Air For Thai" initiative, in collaboration with the Research Institute for Health Sciences (RIHES), Chiang Mai University, which provides academic support and impact assessment. The company has launched the "Share the Air" campaign, offering "Friend Pack" air purifier sets (2 units) at a special price of THB 1,299. Customers can choose to keep both units, buy one and donate one, or donate both sets to support vulnerable groups and under-resourced childcare centers in Chiang Mai and across Northern Thailand. In addition, customers who spend THB 1,299 or more at participating Central shopping centres will receive a complimentary box of "Share the Air" face masks (limited quantity; one redemption per person per day). Interested participants can join the campaign at redemption counters at four Central shopping centres in Northern Thailand.

For people in other regions across Thailand, contributions can also be made to the "Fresh Air For Thai," with donations eligible for tax deduction. Donations can be made to account number 566-3-044299 at Siam Commercial Bank, Faculty of Medicine Branch, Chiang Mai University, to support children and vulnerable groups in Northern communities. Furthermore, the company is preparing to provide urgent support to wildfire volunteer units in Northern Thailand as part of its immediate response efforts.

Professor Dr. Kriengkrai Srithanaviboonchai, Director of the Research Institute for Health Sciences, Chiang Mai University, said, "We would like to express our sincere appreciation to Central Pattana and all partners for recognizing the urgency of the PM2.5 issue and for driving systematic solutions to sustainably improve the well-being of people in Northern Thailand. To date, the project has delivered over 2,500 'Clean Air Boxes'DIY air filtration and ventilation unitsand has developed more than 550 dust-free classrooms in child development centers. These efforts have benefited over 18,000 children and 1,700 teachers across Chiang Mai, Chiang Rai, Mae Hong Son, Lampang, Lamphun, and Nan. The initiative helps reduce exposure to PM2.5 pollution while empowering educational institutions to sustainably produce their own clean air solutions."

To ensure continuity and broader impact, Central Pattana plans to evolve toward a "Creating Shared Value Regional Movement." This initiative aims to elevate its shopping centers in each region and connect its business ecosystem as collaborative platforms, bringing together the public sector, private sector, academia, agricultural communities, and local organizations. Through localized activities and campaigns, the company will also foster public participation, with the goal of transforming the role of the private sector from crisis responder to a regional collaboration platformdriving positive, long-term impact on people's quality of life in a sustainable way.
