As of Saturday, March 1, 2025, Dhaka, the capital of Bangladesh, has recorded the worst air quality globally, with an Air Quality Index (AQI) reaching 304, classified as ‘hazardous’.
The AQI is a standardized tool used worldwide to measure air pollution levels, with higher values indicating greater health risks. An AQI over 300 is deemed hazardous, posing serious health threats to the entire population. Such elevated pollution levels can lead to severe respiratory issues, cardiovascular diseases, and other health complications.
The primary contributors to Dhaka’s deteriorating air quality include emissions from vehicles, industrial activities, construction dust, and the burning of waste materials. The city’s rapid urbanization has exacerbated these issues, leading to increased pollution levels.
This isn’t an isolated incident; Dhaka has consistently ranked among the world’s most polluted cities in recent years. From 2018 to 2021, it was the second most polluted city globally. The World Bank reported that air pollution caused approximately 78,145 to 88,229 deaths in Bangladesh in 2019, underscoring the severe health implications of prolonged exposure to polluted air.
Addressing this critical issue requires immediate and coordinated efforts from both the government and the public. Implementing stricter emission standards, promoting the use of cleaner energy sources, enhancing public transportation, and increasing green spaces are essential steps toward improving air quality. Public awareness campaigns are also vital to educate citizens about the health risks associated with air pollution and the importance of adopting eco-friendly practices.
The current hazardous air quality in Dhaka serves as a stark reminder of the urgent need for comprehensive measures to combat air pollution, ensuring a healthier environment for all residents.
