  • Smog-prone regions near Beijing and Shanghai posted big improvements in air quality in late 2019, but pollution in other parts of China worsened as dirty industries were relocated rather than shut down, researchers said on Thursday.
  • The two regions were on track to meet their target of cutting average concentrations of hazardous airborne particles, known as PM2.5, by 4 percent and 2 percent respectively over the six months to March 2020.
  • Average nationwide PM2.5 concentrations fell 2.9 percent to 34 micrograms per cubic meter from January to November 2019.
