For CO2 as global warming substance, emission factor of gasoline vehicle was calculated under running mode and compared with theoretical value of TRIAS, and yearly trend of CO2 emission in Japan was calculated from emission factor and statistical gasoline marketing amount data. CO2 amount (TRIAS)-emitted gasoline vehicle (emission factor) is 2.38 kg/l, but the factor calculated from exhaust gas analytical value of actual running mode was 2.32 kg/l (constant speed running mode; 2.35 kg/l), affected by CO, HC and particulates in exhaust gas. CO2 emission showed the lowestvalue at vehicle speed about 50 km/h and showed the higher value at lower speed side and higher speed side. CO2 total emission from gasoline vehicle in Japan was calculated as 89, 293×103 ton in 1987 and it showed the small increase almost every year. Increasing ratio of a year was about 3-9% in 1971 to 1978 and about 2% in 1979 to 1987.
