China’s Efforts to Fight Pollution are Working


Back in 2014 China decided it was sick of producing so much pollution and decided to do something about it. China started to close coal plants, spent $120 billion cleaning air in cities and launched similar initiatives throughout the country. The results have been longer life spans for people in impacted areas and a more efficient economy. The rapid pace of change is impressive even for China as no other country has been so quick to reduce pollution, that being said China has a long way to go to reach WHO standards seen in the rest of the world.

Although most regions outpaced their targets, the most populated cities had some of the greatest declines. Beijing’s readings on concentrations of fine particulates declined by 35 percent; Hebei Province’s capital city, Shijiazhuang, cut its concentration by 39 percent; and Baoding, calledChina’s most polluted city in 2015, reduced its concentration by 38 percent.

To investigate the effects on people’s lives in China, I used two of my studies (more here and here) to convert the fine particulate concentrations into their effect on life spans. This is the same method that underlies the Air Quality-Life Index that can be explored here. These studies are based on data from China, so they don’t require extrapolation from the United States or some other country with relatively low concentrations of pollution.
