Thailand Battles Bangkok’s Air Pollution with Dry Ice—But Does It Work? | Planet Pulse

As Bangkok struggles with hazardous air pollution, Thailand has turned to an unconventional solution—spraying dry ice from aircraft in an attempt to disperse the thick smog. The experimental method, developed by the Royal Rainmaking Department, involves releasing dry ice or cold water into the atmosphere to break up trapped pollutants. While officials claim the technique helps reduce PM2.5 levels, critics argue there’s little scientific evidence to support its effectiveness. Adding to the controversy, major energy companies—including Thailand’s oil and gas giant PTT—are funding the project, raising eyebrows about their motivations. With each flight costing up to $1,500 and multiple aircraft taking off daily, experts question whether Bangkok should focus instead on proven measures, such as stricter vehicle emissions controls and agricultural burn bans.
