Pakistan’s two largest cities, Lahore and Karachi, are once again grappling with dangerously poor air quality, ranking among the top five most polluted cities in the world, according to the latest data from IQAir’s global Air Quality Index (AQI).
Lahore has secured the second position worldwide with an AQI reading of 284, which falls under the “very unhealthy” category. Despite the Punjab government’s ongoing anti-smog measures, including the deployment of water sprinklers and smog guns, pollution levels continue to rise as winter sets in.
In Karachi, the situation remains alarming as well. The port city recorded an AQI of 161, classed as “unhealthy,” placing it fifth globally on the list. Environmental experts attribute this to unchecked vehicular emissions, industrial waste, and the absence of effective urban air regulation.
The worsening air quality in both cities highlights Pakistan’s growing environmental challenges, driven by rapid urbanization, crop burning, and a lack of sustainable transportation infrastructure. Experts warn that the health implications are serious, especially for children, the elderly, and individuals suffering from asthma or other respiratory conditions.
According to health specialists, prolonged exposure to toxic air can lead to long-term respiratory diseases, cardiovascular issues, and weakened immune systems. They advise residents to wear masks, avoid unnecessary outdoor activity, and use air purifiers indoors whenever possible.
Globally, Delhi leads the list with a hazardous AQI of 333, followed by Lahore at 284, Kolkata at 168, Dubai at 162, and Karachi at 161. Other cities in the top ten include Dhaka, Manama, Tashkent, Shanghai, and Bishkek, illustrating a wider regional air pollution crisis across South and Central Asia.
Despite promises from local governments to enforce stricter anti-smog regulations, Pakistan continues to struggle with consistent air quality management. Environmentalists stress the need for sustainable urban planning, cleaner industrial operations, and stricter emissions controls if the country hopes to protect public health and reduce its pollution footprint.
Until then, citizens of Lahore and Karachi are urged to take all necessary precautions as they continue to breathe some of the most toxic air in the world.
