In order to estimate the emission inventory for fugitive dust from concrete batching plants accurately, emission factors for fugitive dust from concrete batching plants in USEPA and SCAQMD were synthesized in this paper, and road silt loading were carried out in typical concrete batching plants in Beijing, emission factors for fugitive dust of production segments and comprehensive process from concrete batching plants were established in Beijing. Combining with fugitive dust managing process from concrete batching plants in Beijing, fugitive dust emission inventory from concrete batching plants in Beijing from 1991 to 2014 was estimated, and predicted for the year of 2015 to 2020. Results showed that the mean value of road silt loading of concrete batching plants is (26.2±11.5)g/m2 in Beijing in 2015, which is 2.4 times as much as the value (11.0g/m2) recommended by SCAQMD. Fugitive dust from concrete batching plants in Beijing before 1995 was uncontrolled, the comprehensive emission factor of PM2.5 was 86g/m3 concrete, the uneven factor of monthly of production output of concrete batching plants in first quarter was 1/3 of other quarters. The comprehensive emission factor of PM2.5 in 2015 was declined 89.4% compared with 1995, and proportion of plant fugitive road dust emission from plants in total emission was increased from 10% to 70%. After implementation of "Beijing's Clean Air Action Plan from 2013~2017", PM2.5 emission from concrete batching plants was fell to 543.1t/a and decreased by 48.3% in 2015 compared with 2013. The contribution of elimination of unqualified concrete batching plants to PM2.5 emission reduction was 18.6%. Fugitive dust emission from concrete batching plants in Beijing concentrates on the fifth ring road to sixth ring road (52%), the emission amount of outside of sixth ring road account for 28% of total amount. In the future, eliminating unqualified concrete batching plants continuously and strengthening road sweep cleaning in plants should be the most important emission reduction efforts of concrete batching plants in Beijing.
