With　the　rapid　growth　of　urban　motor　vehicle　ownership,　parking　difficulties　and　increased　carbon　emissions　have　emerged　in　many　cities.　Parking　is　an　important　part　of　the　transportation　system,　and　reducing　carbon　emissions　during　the　parking　process　has　become　an　important　topic.　This　paper　focuses　on　reducing　carbon　emissions　in　the　parking　process　and　aims　to　propose　a　parking　space　arrangement　method　which　considering　lower　carbon　emissions.　First　the　size　and　number　of　parking　spaces　of　different　parking　methods　are　studied,　and　the　carbon　emissions　generated　by　different　parking　processes　are　analyzed.　For　nine　different　parking　space　layouts,　the　number　of　parking　spaces　and　carbon　emissions　were　calculated.　The　results　show　that　the　combined　parking　space　can　achieve　the　optimal　balance　between　parking　space　and　carbon　emissions.　©　ASCE.
