BANGKOK, THAILAND – Bangkok’s authorities unveiled a sweeping ten-point plan to curb deadly fine dust pollution, including mass home working and tougher emissions controls.
Mass home-working push to cut commuter pollution
In the current year, about 200,000 employees from 368 agencies were connected to the city’s home-working network, a figure that was planned to rise to 300,000 in 2025. The system was divided into two stages: a mandatory work-from-home regime for periods of extreme air pollution and a proactive, regular measure. Under the proactive scheme, all agencies were to offer at least one day of home office per week from January 2025 to March 2026.
Mandatory WFH triggered by three pollution indicators
Compulsory home-working was set to take effect only when three conditions were met at the same time. PM2.5 readings had to reach the orange level of 51–72 micrograms per cubic metre in 35 or more districts. In addition, ventilation had to be poor and more than 80 fire hotspots per day in the city had to be reported for three consecutive days.
Governor presents ten-point anti-smog package
Bangkok Governor Chadchart Sittipunt presented a comprehensive ten-point package of measures on Monday. He acknowledged that the persistent pollution was caused by stagnant air, vehicle emissions and biomass burning. The National Environment Board had already designated Bangkok as a smog-control zone from November to March.
Low-emission zone extended to all 50 districts
A central element of the plan was the expansion of the city’s low-emission zone so that it would cover all 50 districts of Bangkok. Vehicles with particularly high emissions, such as trucks, would face stricter rules, with the allowed soot emission level reduced from 30% to a tighter 20%. Roadside checks were to be significantly increased, and the BMA aimed to register 500,000 vehicles on a “Green List Plus” whose owners carried out regular maintenance.
Industry, construction and farming face tighter rules
On the industrial and construction side, all facilities with boilers were required to install continuous emissions monitoring systems. Cooperation with surrounding provinces was to be strengthened in order to curb agricultural field burning, identified as a main cause of regional smog. By March, all planned dust-free rooms in schools and kindergartens were to be completed, adding to the more than 1,000 such rooms already in place.
New alert system to push air-quality warnings to phones
To warn residents more effectively, the BMA planned to introduce a new cell-broadcast system so that alerts about poor air quality would arrive directly as push notifications. Public information campaigns on social media were to be intensified. The message from the authorities was that Bangkok’s fight against smog would not ease.
“People will have to adjust to restrictions, but also to better air.”
said city officials, summarising the hard line the administration had taken.
