Hanoi's streets suffer from air pollution

A man wearing a mask rides a bicycle on a street in the Vietnamese capital, Hanoi. According to the latest air quality index classification, conducted by the Air Visual Index, Hanoi is among the most polluted cities in the world. In 2019, the government announced plans to monitor air pollution. Vietnamese environment ministers said they intend to establish a network of state-supervised air monitoring stations across the country. These efforts have not succeeded, so far, in curbing pollution, which worsens year after year.
