ULE's annual power sector emissions of sulphur dioxide (SO2), nitrogen oxides (NOx) and particulate matter (PM) dropped by 65%, 60% and 72% respectively between 2014 and 2017 due to ultra-low emissions (China) standards for coal-fired power stations, according to a study from Chinese and British researchers. ULE introduced the China policy in 2014 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.
