The　vehicular　NMVOCs　emission　in　China　was　estimated　based　on　the　emission　factors　calculated　by　COPERT　model.　The　total　vehicular　NMVOCs　emission　is　4073.0　Gg　in　2011.　Passenger　cars　(PC),　motorcycles　(MC)　and　buses　(BUS)　have　higher　contributions　among　different　vehicle　types.　Vehicles　with　State　0,　State　I　and　State　II　are　the　main　contributor　to　the　vehicular　emissions,　with　proportion　of　approximately　26.7%,　31.2%　and　24.1%,　respectively.　Guangdong,　Shandong,　Hebei　and　Jiangsu　have　larger　NMVOCs　emissions.　The　NMVOCs　species　emission　and　ozone　formation　potentials　(OFP)　were　also　calculated.　The　ten　key　species　for　emission　and　OFP　were　identified,　respectively.　They　are　ethylene,　toluene,　benzene,　isopentane,　propene,　m,p-xylene,　2-methylpentane,　ethane,　1,2,4-trimethylbenzene,　1-butene　and　ethylene,　propene,　m,p-xylene,　1,2,4-trimethylbenzene,　1-butene,　toluene,　2-methyl-2-butene,　m-ethyltoluene,　o-xylene,　1,3,5-trimetylbenzene,　respectively.　The　results　can　provide　scientific　support　for　making　effective　vehicular　emission　reduction　and　air　quality　improvement　measures.　©　(2014)　Trans　Tech　Publications,　Switzerland.
