This　research　examines　the　energy　consumption　and　pollution　emission　of　civil　vehicles　in　Beijing　during　the　period　from　2008　to　2020.　The　paper　studies　the　phenomenon　of　interest　with　the　Long-range　Energy　Alternatives　Planning　System　with　two　different　scenarios:　the　continuation　of　current　policies　on　fuel　consumption　and　pollutant　emission,　versus　the　new　and　stricter　fuel　consumption　standard　and　pollutant　emission　regulations.　With　the　assumption　that　the　number　of　civil　vehicles　will　increase　from　3.14　million　in　2008　to　7　million　in　2020,　the　study　reached　the　conclusion　that　under　the　new　policies　on　fuel　consumption　and　pollutant　emission　the　energy　consumption　by　civil　vehicles　in　2020　will　be　240%　of　that　in　2008,　and　the　emission　of　major　air　pollutant　will　increase　significantly.
