Researchers from China, France and the U.S. have evaluated China's success in stemming emissions from its coal-fired power plants (CPPs).
CPPs are one of the main contributors to air pollution in China, and their proliferation over the last 20 years has had significant impacts on air quality and public health.
Impacts - Authorities - Measures - Emissions - CPPs
These impacts led authorities to introduce measures to control emissions from CPPs and reduce their effects.
Writing today in Environmental Research Letters, researchers examined if these policies have been effective, and measured their benefits.

Dr. Qiang Zhang, from Tsinghua University, China, is the study's lead author. He said: "Between 2005 and 2015, the coal-fired power generation of CPPs in China grew by more than 97 percent. In 2010, CPPs' sulphur dioxide, nitrogen oxide and fine particulate matter (PM2.5) emissions accounted for 33 percent, 33 percent and 6 percent of China's total national emissions, respectively. The large amount of air pollutant emissions from CPPs causes fine particulate air pollution, which contributed 26 percent of the fine particulate nitrate and 22 percent of the fine particulate sulphate ambient concentration in 2012.
"To combat this, China introduced three primary policies for CPPs during 2005-2020. They aimed to improve efficiency energy by promoting large CPPs and decommissioning small plants during 2005-2020; brought in national emission cap...
