Abstract: Traffic is one of the main air pollution source in urban cities, especially in Ho Chi Minh City. Annually, it emits a huge amount of pollutants into the atmosphere; and air quality in HCMC becomes worse due to circulation of outdate private vehicles. Therefore, clean air plan (CAP) is necessary for reducing air pollution level in the city and air emission inventory (EI) is an essential step to develop CAP. Mobilev model from Germany was chosen to conduct EI for HCMC. Objectives include of this study: (i) elaborating an air emission inventory (EI) from road traffic activities over HCMC; and (ii) assessing emission control policies and study abatement strategies to reduce air pollution level from traffic activities for HCMC in 2020. The results indicated that motorcycles are the main sources of air emission in HCMC. The emissions of CO are 3,586.707 tons/year, following ish VOC, NOx, CH4, NO2, SO2 and particulate matter (PM). In addition, CO2, which is one of the main greenhouse gases, also included and contributed 36,293.501 ton/year. These pollutants concentrated in the center which has crowded roads and population, affecting directly human health. Therefore, a replaced private vehicle with public transportation is necessary to reduce emissions. Two abatement strategies to 2020 for reducing emissions were performed and showed that if the HCMC government has severe policies on motor vehicles, the emission will be reduced until 60%, opposite emissions in 2020 will be increased to 200%.
