# Skyward Solutions: Thailand’s Battle Against Air Pollution - Link: https://www.thailand-business-news.com/environment/191493-skyward-solutions-thailands-battle-against-air-pollution - Published: 2025-01-28T08:22:43+07:00 - Author: Arun Upadhyaya **Thailand’s experimental aerial spraying aims to combat severe air pollution in Bangkok, despite doubts about its effectiveness. Critics urge addressing pollution sources directly rather than relying on unproven methods.** --- ## Key Points * In Bangkok, a small aircraft sprays a white mist in a bid to combat severe air pollution, which has reached eight times the WHO’s recommended limits, affecting over a million people and costing Thailand $88 million in medical expenses since late 2023. * The Royal Rainmaking department employs an experimental method of spraying cold water and dry ice to cool warm air, aiming to disperse trapped PM2.5 particles. Critics question its effectiveness, highlighting it as unproven compared to traditional cloud seeding. * Despite the cost and environmental concerns of using dry ice, local authorities emphasize ongoing efforts to improve air quality through proven measures like low-emissions traffic zones, advocating for confidence in data before implementing unconventional solutions. In an innovative yet controversial effort to combat severe air pollution, a small aircraft is deployed over Bangkok to spray a white mist intended to alleviate the city’s oppressive smog. The pollution levels recently peaked at eight times higher than the World Health Organization’s daily recommended maximum, affecting over a million residents and costing Thailand upwards of US$88 million in medical expenses since late 2023. Factors contributing to this crisis include vehicle emissions, regional crop burning, and atmospheric conditions that trap pollutants near the ground. ADVERTISEMENT The Royal Rainmaking Department’s unproven method—using aircraft to release cold water or dry ice—aims to cool the warmer air overlaying trapped particulate matter( PM2.5), facilitating its dispersal into the upper atmosphere. Notably, this technique diverges from traditional cloud seeding methods, which typically involve silver iodide to induce rain. Critics, however, question the effectiveness of both approaches, citing scant evidence for significant improvements in air quality. Despite claims from program head Chanti Detyothin that preliminary data suggests reduced concentrations of PM2.5, he acknowledges the method’s limitations in tackling the pollution crisis entirely. The initiative relies heavily on support from fossil fuel companies that provide dry ice, raising concerns about the environmental ramifications of introducing more greenhouse gases into the atmosphere. There is a broader call for more sustainable and proven measures to address pollution at its sources, such as reducing vehicle emissions and regulating agricultural burning. Critics argue that the current strategy may serve more to bolster corporate image rather than effectively resolve the pressing issue of air quality that significantly impacts public health in Bangkok. ### Related**Posts** ### 󠀁[Thai Listed Companies Face Nearly $11 Billion in Annual Climate‑Risk Costs by 2050, S&P Global Warns](https://www.thailand-business-news.com/environment/329326-thai-listed-companies-face-nearly-11-billion-in-annual-climate-risk-costs-by-2050-sp-global-warns)󠁿 ### 󠀁[Time to Rewrite Energy Rules: Unavoidable Transition for Thailand](https://www.thailand-business-news.com/environment/329524-time-to-rewrite-energy-rules-unavoidable-transition-for-thailand)󠁿 ### 󠀁[Thailand floods disrupt Toyota production and Thai Airways cargo operations](https://www.thailand-business-news.com/environment/331911-thailand-floods-disrupt-toyota-production-and-thai-airways-cargo-operations)󠁿 ### 󠀁[Bangkok floods threaten to shave 0.3 percentage points from Thailand’s 2026 growth](https://www.thailand-business-news.com/environment/331475-bangkok-floods-threaten-to-shave-0-3-percentage-points-from-thailands-2026-growth)󠁿
