The Bangkok Mass Transit Authority (BMTA) has introduced stricter regulations to curb the pollution caused by public buses in Bangkok. In response to increasing concerns about air quality, the BMTA now requires each bus to undergo daily emissions testing before being allowed to operate. This initiative comes after a directive from Deputy Transport Minister Surapong Piyachote, aiming to address the rising levels of air pollution and associated health risks in the city.
In a bid to strengthen enforcement, the Ministry of Transport has implemented stricter maintenance procedures for the capital’s public buses. Routine inspections are now being conducted at bus depots, and workshops are instructed to carry out more frequent cleanings and maintenance work. These actions specifically target aging diesel-powered buses, which are known to contribute significantly to harmful emissions.
The BMTA has also revised the allowable black smoke emission limit from 30% to 20%. Testing is now conducted during both the morning and afternoon shifts to ensure consistent monitoring. Any bus that exceeds this new threshold is immediately taken off the road for repairs. Maintenance contractors and vehicle inspection teams have been tasked with ensuring that all buses meet the updated standards before returning to service.
With air pollution continuing to be a pressing concern, Surapong emphasized that the government will maintain strict oversight of emissions from public buses. The ongoing enforcement of these regulations is part of a broader effort to reduce levels of particulate matter (PM2.5) and improve air quality for both residents and commuters in Bangkok.
In addition to Surapong’s remarks, the Ministry of Transport and BMTA officials are actively overseeing the implementation of these measures, reinforcing the government’s commitment to improving urban air quality.
