According to the China Coal Processing and Utilization Association, for every 100 million tons of raw coal enrolled, about 18 million tons of coal gangue can be excluded. Approximately 13 million tons of ash and 3.5 × 10 5 tons of sulfur could be excluded, and 4.9 × 10 4 tons of SO 2 emissions could be reduced.
With these efforts, Beijing has experienced a remarkable de-coal process with two stages of relative decline (1985–2005) and absolute decline (2005–2017). Between 1985 and 2005, the share of coal consumption decreased from 66.1% to 43.4% of Beijing's total energy consumption. Coal consumption in Beijing peaked in 2005, with 21.9 Mtce.
