China's annual power sector emissions of sulphur dioxide (SO2), nitrogen oxides (NOx) and particulate matter (PM) dropped by 65%, 60% and 72% respectively 2014between 2014 and 2017 and 2017 due to ultra-low emissions (ULE) standards for coal-fired power stations, according to a study from Chinese and British researchers. China introduced the ULE policy in between 2014 and 2017 to limit SO2, NOx and PM from the plants to 35, 50 and 10 mg m-3. The study uses real-world data from a monitoring system covering 98% of Chinese thermal power capacity, and finds lower emissions than previous studies, with the authors highlighting the importance of their methodology and of post-policy evaluation.
