Fuel-based inventory of NOx and SO2 emissions from motor vehicles in the Hiroshima Prefecture, Japan

摘要: Abstract In order to attain the 2010 target of reducing national greenhouse gases by 6% 1990 level, with reference Kyoto Protocol, Government Japan has planned and implemented some measures, as well related policies. This paper discusses possible impact these measures on nitrogen-oxide sulfur-dioxide emissions from road vehicles in Hiroshima Prefecture (ca. 3 million population). The number based vehicle fuel types for 1990–2000 are presented, projections years 2005 using Gompertz model. Three scenarios were developed assess emissions, referring achievement policies new technologies. Prediction results show that may be decreased 14.7 kton 9.3 if Japanese energy-policy developments successfully implemented. If they less implemented, will decrease slightly 14 kton, which was mostly gasoline vehicle. emission sulfur dioxide projected 1.2 within range 0.45–0.49 2010, a result reduce content diesel oil.
