Promoted　by　carbon　neutrality　and　solid　iste　policies,　iron-　and　steelmaking　iste　slag　(ISWS)-based　glass-ceramics　have　drawn　attention　because　of　their　contribution　to　achieving　the　net-zero　carbon　emissions　goal　for　the　iron-　and　steelmaking　industry.　However,　a　holistic　estimation　of　the　preparation,　property　and　GHG　(greenhouse　gas)　emission　abatement　of　ISWS-based　glass-ceramics　is　still　under　exploration.　In　this　paper,　research　progress　on　preparing　glass-ceramics　from　ISWS　discharged　from　the　traditional　iron-　and　steelmaking　industry　is　reviewed.　Then,　the　influence　of　ISWS＇s　chemical　characteristics　on　the　preparation　of　glass-ceramics　and　the　products＇　performance　are　discussed.　In　addition,　the　potential　of　GHG　emission　reduction　related　to　the　promotion　of　ISWS-based　glass-ceramics　is　measured.　It　is　found　that　ISWS-based　glass-ceramics　can　avoid　0.87-0.91　tons　of　CO2　emissions　compared　to　primary　resource　routes.　A　scenario　simulation　is　also　conducted.　If　the　technology　could　be　fully　applied　in　the　ironmaking　and　steelmaking　industries,　the　results　suggest　that　2.07　and　0.67　tons　of　indirect　CO2　reductions　can　be　achieved　for　each　ton　of　crude　steel　production　from　blast　furnace-basic　oxygen　furnace　(BF-BOF)　and　electric　arc　furnace　(EAF)　routes,　respectively.　Finally,　a　＂dual　promotion＂　economic　mode　based　on　national　policy　orientation　and　the　high　demands　on　metallurgical　iste　slag　(MWS)-based　glass-ceramics　is　proposed,　and　the　application　prospects　of　MWS-based　glass-ceramics　are　examined.　These　application　prospects　will　deepen　the　fundamental　understanding　of　glass-ceramic　properties　and　enable　them　to　be　compounded　with　other　functional　materials　in　various　new　technologies.
