Abstract: This paper applies COPERT, a vehicular pollutant emission factor model, to calculate the emission factors of CO, CO₂ , NO_x , PM₂ , NMVOC, SO₂ , N₂ O, CH₄ , and NH₃ , for various vehicle categories including gasoline passenger cars, diesel passenger cars, LPG passenger cars, gasoline hybrid passenger cars, gasoline light duty vehicles, diesel light dutyvehicles, gasoline heavy duty vehicles, diesel heavy duty vehicles, buses, CNG buses, biodiesel buses, and motorcycles with different emission standards of Euro 0, Euro Ⅰ, Euro Ⅱ, Euro Ⅲ, Euro Ⅳ, Euro Ⅴ, and Euro Ⅵ, in consideration of factors including driving conditions, oil quality, and ambient temperature which have an impact on vehicular emission factors. The results provide scientific evidence and data support for the estimation of recent and future vehicular emission inventories in China, for the improvement of decision-making and management of vehicular pollution control, and for the assessment of the implementation effect of vehicular pollution control policies and measures.
