China Reduces Major Air Pollution By 60-72% From 2014 to 2017

  • The team found that between 2014 and 2017, China’s annual power plant emissions of sulphur dioxide, nitrogen oxide and particulate matter dropped by 65%, 60% and 72% each year respectively from 2.21, 3.11 and 0.52 million tonnes in 2014 to 0.77, 1.26 and 0.14 million tonnes in 2017, under the ultra-low emissions (ULE) standards policy.
  • The research is the first to use data on emission concentrations collected by China’s Continuous Emission Monitoring Systems network (CEMS) which covers 96-98% of Chinese thermal power capacity.
  • In 2014, China introduced an ultra-low emissions (ULE) standards policy for renovating coal-fired power-generating units to limit SO2, NOx and particulate matter (PM) emissions to 35, 50 and 10 mg m−3, respectively.
