Pakistan is ranked among the top five countries for severe air pollution, with PM2.5 levels far exceeding WHO standards. Major cities face intense smog, worsened by the recent end of the US air quality monitoring program, leaving the country vulnerable to data gaps. Climate change is intensifying the pollution crisis, making urgent action necessary.
Pakistan ranks among the world’s most polluted countries, continuing to struggle with severe air quality issues as per new data released. The country has been identified as one of the top five most smog-affected nations alongside Chad, Bangladesh, the Democratic Republic of Congo, and India. Hazardous levels of particulate matter (PM2.5) in Pakistan far exceed the World Health Organization’s (WHO) safe limit of 5 micrograms per cubic meter, with only 17% of global cities meeting this standard last year.
Major urban areas like Lahore and Karachi frequently experience intense pollution, especially in winter when fog and industrial emissions combine to exacerbate the air quality crisis. This ongoing smog issue is a significant health risk and hampers Pakistan’s initiatives aimed at improving air quality.
The reliance on external monitoring for air quality data poses additional challenges. Historically, the US State Department operated air quality sensors at its embassies and consulates, providing crucial pollution data for Pakistan. However, this program has recently been terminated due to budget constraints, leaving the country at risk of missing valuable pollution data essential for managing air quality effectively.
Christi Chester-Schroeder from IQAir emphasized the negative impact on countries like Pakistan, where US monitoring stations were critical for obtaining real-time air quality information. She remarked, “The loss of these monitoring stations is a major blow to efforts in regions where pollution data is sparse.”
With rising global pollution levels, climate change is exacerbating the situation. Increased temperatures contribute to prolonged and severe forest fires in regions such as Southeast Asia and South America, further deteriorating air quality. The conclusion of the US monitoring program could impact over 34 countries, imperiling essential pollution data.
Christa Hasenkopf from the University of Chicago underscored the significance of the program’s closure, calling it “a giant blow to air quality efforts worldwide.” Pakistan’s battle against air pollution is becoming increasingly arduous, highlighting the need for reliable air quality monitoring and stringent pollution control measures to combat the smog crisis efficiently.
Pakistan’s persistent struggles with severe air pollution place it among the world’s most affected countries, exacerbated by the recent termination of the US air quality monitoring program. The alarming levels of PM2.5, particularly in urban centers, indicate an urgent need for effective pollution management. The interplay of climate change further complicates the country’s efforts, underscoring the necessity for robust data and control measures to address the crisis.
