Does China still have smog?
This represented significant progress, but China still has a considerable problem with its air quality today. The annual average concentration of fine particulate matter (PM2. 5) across China was 57 micrograms per metre cubed in 2017, nearly six times what the World Health Organisation deems to be acceptable limits.
How bad is China’s air quality?
Beijing’s peak average daily AQI in 2020 reached 262, which the EPA considers very unhealthy. High levels of air pollution take a major toll on public health. A study by the Health Effects Institute found that unhealthy levels of PM2. 5 led to roughly 1.42 million premature deaths in China in 2019.

Dur- ing the 1970s, black smoke from stacks became the characteristic of Chinese industrial cities; in the 1980s, many southern cities began to suffer serious acid rain pollution; and recently, the air quality in large cities has deteriorated due to nitrous oxides (NOx), car- bon monoxide (CO), and photochemical smog.
