The　ISO14046　water　footprint　evaluation　method　was　used　in　this　study　to　calculate　the　water　shortage　footprint　and　water　degradation　footprint　in　plate　glass　production,　in　order　to　improve　the　water　efficiency　and　management　level　in　the　production　process　of　plate　glass　in　China.　A　certain　enterprise　in　Hebei　province　was　selected　for　investigation　in　2018.　The　results　show　that　the　water　shortage　footprint　generated　by　the　production　of　flat　glass　was　0.435　m3　H2Oeq/weight　box.　The　proportion　at　raw　material　production　stage　was　the　largest,　being　86%,　so　the　water　consumption　control　in　raw　material　mining　and　the　circulating　water　system　should　be　strengthened　and　improved　to　reduce　the　fresh　water　consumption.　Water　degradation　footprint　in　flat　glass　industry　mainly　consisted　of　eutrophication　and　acidification　footprints.　The　eutrophication　footprint　was　calculated　as　0.027　kgNO3-eq/weight　box,　and　water　acidification　footprint　was　0.271　kgSO2eq/weight　box.　The　largest　proportion　occurred　at　flat　glass　production　stage.　It　should　be　paid　attention　at　this　stage,　to　update　the　relatively　clean　production　equipments　and　add　the　waste　gas　processing　steps　to　reduce　pollution　discharge.　©　2021　Trans　Tech　Publications　Ltd,　Switzerland.
