中国原铝生产-2003年 When utilizing this data set for Life Cycle Assessment, it is critical to note that the figures represent the technology and environmental impacts associated with the year 2003 for Chinese aluminum production. Users should take into account advancements in technology and changes in greenhouse gas (GHG) emission factors if applying the data to assessments of current or future processes. The system boundary is limited to bauxite mining, alumina preparation, carbon anode production, aluminum electrolysis process, and ingot casting; thus, users must exclude transportation, plant construction, and equipment maintenance when applying this data set.
