Average PM2.5 levels are almost four times above WHO limits.
Chinese life expectancy can be raised by 3 years
China could raise average life expectancy by 2.9 years if it improves air quality to levels recommended by the WHO, according a new study from the Energy Policy Institute at the University of Chicago. Following a campaign to curb coal use and improve industry and vehicle standards, China has cut average concentrations of hazardous particles (PM2.5) to an average of 39 μg/m3. However, this is still significantly higher than China’s own 35-microgram standard, as well as the 10-microgram limit recommended by the WHO. In China’s northern industrial regions, average concentrations are much higher.
