Hanoi Declared the World’s Most Polluted City

Hanoi, the capital of Vietnam, has been enveloped in thick smog over recent weeks, pushing it to the top of the world’s most polluted cities. According to data from AirVisual, a global air pollution monitoring service, levels of hazardous particles known as PM2.5 were measured at an alarming 266 micrograms per cubic meter early Friday. This is the highest reading among major cities globally.

Causes of Hanoi’s Pollution Crisis

The persistent smog in Hanoi is primarily attributed to heavy traffic, industrial activities, and trash burning. The city, which has long struggled with air quality issues, is now facing heightened concerns as residents report worsening conditions.

“We, the elderly, feel the impact strongly, especially through respiratory problems,” shared Luu Minh Duc, a 64-year-old resident. Younger citizens are also alarmed. “I thought it was fog, but later realized it was fine dust. It’s unhealthy to breathe,” said Nguyen Ninh Huong, a 21-year-old student.

Government Pushes for Electric Vehicles

To combat the escalating air pollution, Deputy Prime Minister Tran Hong Ha urged for a faster transition to electric vehicles (EVs) during a meeting with the transport ministry on Thursday.

The government has set ambitious targets, aiming for at least 50% of buses and 100% of taxis in Hanoi to be EVs by 2030. Ha emphasized the need for swift and concrete actions, stating, “This is the state’s responsibility to the people.”

Experts Warn of Long-Term Challenges

Climate experts believe the pollution is exacerbated by emissions from the city’s vast fleet of motorbikes and cars, coal plants in the north, and agricultural burning.

“The pollution sources remain consistent daily,” said climate expert Huy Nguyen. Current unfavorable weather conditions, such as weak winds and stagnant air, trap pollutants in a “giant atmospheric glass cage.” He noted that residents might have to wait until March for rain and strong northeast monsoons to improve the air quality.
