Globally　2　degrees　C　and　1.5　degrees　C　warming　targets　by　2100　was　set　up　by　Paris　agreement,　and　academically　supported　by　recently　published　IPCC　reports.　However,　feasibility　to　realize　the　emission　pathways　to　reach　the　targets　were　still　under　demanding　from　policy　makers.　In　order　to　analyze　the　feasibility　to　follow　the　emission　pathway　to　reach　2　degrees　C　and　1.5　degrees　C　targets,　Integrated　Policy　Assessment　Model　of　China　(IPAC)　modelling　team　has　worked　on　the　global　emission　pathway　and　emission　scenario　for　China.　This　paper　presents　the　scenario　analysis　by　IPAC　modelling　team　with　focusing　on　energy　and　CO2　emission　scenario　from　transport　sector　in　China,　under　the　national　emission　pathways　to　support　global　2　degrees　C　and　1.5　degrees　C　targets.　Technologies　and　measures　for　deep　cut　of　CO2　emission　in　transport　sector　were　presented.　The　finding　says　energy　and　CO2　emission　scenario　in　transport　could　support　national　2　degrees　C　scenario,　which　requiring　CO2　emission　peak　before　2030,　with　technology　progress　in　transport　and　strong　policies　on　public　transport　and　non-mobility　transport.　However　in　the　1.5　degrees　C　scenario,　CO2　emission　from　transport　need　to　be　near　zero　by　2050.　To　be　such　kind　of　deep　cut　of　CO2　emission　by　2050,　electric　car　and　other　electric　vehicles　have　to　play　crucial　role.　There　is　large　potential　for　electric　car　in　next　decades　in　China　with　technology　progress　by　following　the　roadmap　presented　in　this　paper.
