In this study, we applied energy end-use model to estimate air pollution emissions by considering the use ofenergy devices which are decided from energy demand. In the second, the total emission with time variation that wasemitted from sectors was disaggregated into the regions of target area, and finally, by using the meso-scale metheorologymodel (MM5) and the chemical transfer model (CMAQ), the chemical transformation and transportation at the presentand in the future were computed in the three different spatial scales. Accuracy in long range transportation of thedeveloped model was validated through comparison between the estimated value and the observation by the East Asian Monitoring Networks.<BR>From the result of finest domain, the background concentration of NO₂ was 2-4 ppb in the year average concen trationand about 19 ppb in the maximum of day average concentration, and the possibility was clarified that NO₂ concentrationin Beijing sometimes is pushed up over Chinese standard of air quality by the NO₂ transported from the outside. Moreover, SO₂ and NOx emissions in 2020 were estimated by the end-use model, and the concentration of the each gasin Beijing was calculated and analyzed. As a result, the concentration in 2020 was over three times higher than that in 2001, and it was specially pointed that SO₂ in winter and NO₂ in summer are remarkably high.
