Hanoi targets three major emission sources to combat air pollution

Hanoi is intensifying efforts to control air pollution as the city approaches the high-risk dry season, which typically runs from November to March. Monitoring data from the first nine months of the year shows that air quality has improved significantly compared to the previous year, with good or moderate air quality recorded on 74.42% of days, nearly reaching the annual target of 75%.

Despite these improvements, officials warn that pollution episodes often emerge in October. The Hanoi Department of Agriculture and Environment has identified three primary sources of fine particulate matter (PM2.5) that require targeted management: traffic emissions and road dust, construction and demolition activities, and uncontrolled open burning during harvest seasons.

To mitigate these risks, the city is developing an action plan to focus on these specific emission sources. Measures include strengthening supervision of construction sites, implementing shielding and water spraying protocols, and utilizing monitoring systems to detect and handle illegal open burning.
