However, REE mining and production uses techniques that are often not environmentally sustainable. Life cycle assessment (LCA) is a well-recognized method for evaluating the environmental impacts of products and technologies. This article provides an overview of the environmental impacts based on published LCA results of primary REE production. Existing major REE deposits (Bayan Obo in China, Mountain Pass in the United States, Mount Weld in Australia, ion-adsorption deposits in several Chinese southern provinces) and currently possible production routes are compared. Alternative minerals, such as eudialyte, are also discussed. The article shows which environmental effects can be minimized by technology optimization and environmental safety strategies. Additionally, some of the environmental impacts discussed, may be difficult to mitigate, as they depend on the mineral type. Activities along the complex process chain of REEs production that have particularly high environmental impacts are identified. 000907053 536__ $$0G:(DE-HGF)POF4-1112$$a1112 - Societally Feasible Transformation Pathways (POF4-111)$$cPOF4-111$$fPOF IV$$x0 000907053 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 000907053 7001_ $$0P:(DE-Juel1)130483$$aSchreiber, Andrea$$b1 000907053 7001_ $$0P:(DE-Juel1)130473$$aMarx, Josefine$$b2 000907053 7001_ $$0P:(DE-Juel1)130467$$aKuckshinrichs, Wilhelm$$b3 000907053 773__ $$0PERI:(DE-600)2136359-6$$a10.1557/s43577-022-00286-6$$p267–275$$tMRS bulletin$$v47$$x0883-7694$$y2022 000907053 8564_ $$uhttps://juser.fz-juelich.de/record/907053/files/Zapp2022_Article_EnvironmentalImpactsOfRareEart.pdf$$yOpenAccess 000907053 8767_ $$d2022-11-14$$eHybrid-OA$$jDEAL 000907053 909CO $$ooai:juser.fz-juelich.de:907053$$pdnbdelivery$$popenCost$$pVDB$$pdriver$$pOpenAPC_DEAL$$popen_access$$popenaire 000907053 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130493$$aForschungszentrum Jülich$$b0$$kFZJ 000907053 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130483$$aForschungszentrum Jülich$$b1$$kFZJ 000907053 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130473$$aForschungszentrum Jülich$$b2$$kFZJ 000907053 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130467$$aForschungszentrum Jülich$$b3$$kFZJ 000907053 9131_ $$0G:(DE-HGF)POF4-111$$1G:(DE-HGF)POF4-110$$2G:(DE-HGF)POF4-100$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-1112$$aDE-HGF$$bForschungsbereich Energie$$lEnergiesystemdesign (ESD)$$vEnergiesystemtransformation$$x0 000907053 9141_ $$y2022 000907053 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000907053 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000907053 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2021-01-27 000907053 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2021-01-27 000907053 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz$$d2022-11-29$$wger 000907053 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2022-11-29 000907053 915__ $$0StatID:(DE-HGF)1160$$2StatID$$aDBCoverage$$bCurrent Contents - Engineering, Computing and Technology$$d2022-11-29 000907053 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2022-11-29 000907053 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2022-11-29 000907053 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bMRS BULL : 2021$$d2022-11-29 000907053 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2022-11-29 000907053 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2022-11-29 000907053 915pc $$0PC:(DE-HGF)0000$$2APC$$aAPC keys set 000907053 915pc $$0PC:(DE-HGF)0001$$2APC$$aLocal Funding 000907053 915pc $$0PC:(DE-HGF)0002$$2APC$$aDFG OA Publikationskosten 000907053 915pc $$0PC:(DE-HGF)0113$$2APC$$aDEAL: Springer Nature 2020 000907053 920__ $$lyes 000907053 9201_ $$0I:(DE-Juel1)IEK-STE-20101013$$kIEK-STE$$lSystemforschung und Technologische Entwicklung$$x0 000907053 9801_ $$aFullTexts 000907053 980__ $$ajournal 000907053 980__ $$aVDB 000907053 980__ $$aUNRESTRICTED 000907053 980__ $$aI:(DE-Juel1)IEK-STE-20101013 000907053 980__ $$aAPC
