The　increasing　tendency　toward　consumerism　on　college　campuses　has　emphasized　the　need　for　sustainable　consumption　among　college　students.　Measuring　students＇　sustainable　consumption　behavior　using　the　ecological　footprint　of　their　campus-life　consumption,　we　empirically　examine　how　educational　support　influences　students＇　sustainable　consumption　decisions.　The　results　reveal　that　college　students＇　sustainable　consumption　still　needs　to　be　improved.　Educational　support　not　only　directly　affects　sustainable　consumption　intention　but　also　generates　a　chain　mediation　effect　of　subjective　norms,　perceived　behavioral　control,　attitude,　and　behavioral　intention.　However,　educational　support　does　not　seem　to　facilitate　the　transformation　of　consumption　intention　into　consumption　behavior,　showing　inconsistency　between　awareness　and　behavior　or　the　＂easier　to　know　than　to　do＂phenomenon.　This　study　provides　insight　on　strengthening　sustainable　consumption　education,　converting　students＇　knowledge　of　sustainable　consumption　into　action,　and　guiding　the　whole　society　toward　sustainable　consumption.　　©　2023　ACM.
