Pakistan among six nations bearing the brunt of pollution health burden

Bangladesh and India also on the list; Asia and Africa are the worst effected regions
SINGAPORE (Reuters) – Pakistan is among those six countries in which around three quarters of the adverse health effects of air pollution are concentrated, shows the annual Air Quality Life Index (AQLI) report released by the University of Chicago's Energy Policy Institute (EPIC) on Tuesday.
The six nations listed in the report are: Bangladesh, India, Pakistan, China, Nigeria and Indonesia.
Despite improvements in China, the report warns, air pollution across the globe continues to pose the greatest external risk to human health, with countries in Asia and Africa suffering most of the impact.
If hazardous airborne particles known as PM2.5 were brought down to levels recommended by the World Health Organization (WHO), average life expectancy would rise by 2.3 years worldwide, saving a combined 17.8 billion life years, the report estimated.
While average world pollution levels have fallen slightly over the past decade, almost all of the improvement has been driven by China, where a 10-year "war on pollution" has seen PM2.5 fall by more than 40 per cent since 2013.
"While China has had remarkable success in its war against air pollution, the trend in other parts of the world is going in the opposite direction," said Christa Hasenkopf, AQLI's director.
PM2.5 in South Asia has risen by nearly 10pc since 2013, she said, cutting average life expectancy in the region by around five years. Growing energy consumption in central and western Africa was also turning particulate pollution into a growing health threat on par with HIV/AIDS and malaria.
Virtually all of Southeast Asia is also now considered to have "unsafe levels of pollution", with average life expectancy cut by 2-3 years.
China's average PM2.5 concentrations stood at 29 micrograms per cubic metre in 2022, but it still remains significantly higher than the WHO recommendation of 5 micrograms.
While improvements in China have helped raise average life expectancy by 2.2 years since 2013, it could rise by another 2.5 years if the country were to meet the WHO standard.
"We haven't turned the corner on air pollution yet, though China's example shows us that the issue is a tractable one," Hasenkopf said.
Earlier this year, a global survey had said that Lahore jumped more than 10 places to become the city with the worst air in the world in 2022.
The report published by IQAir mentioned that Lahore's air quality worsened to 97.4 micrograms of PM2.5 particles per cubic meter from 86.5 in 2021, making it the most polluted city globally.
