中国原铝生产-2008年 When using this LCA data set, users should consider the system boundary provided, which includes bauxite mining, alumina preparation, carbon anode production, aluminum electrolysis process, and aluminum ingot casting. Users should note that the data does not include the impacts of transport, plant construction, and equipment maintenance. For accurate LCA results, it is critical to include these additional processes separately if they are part of the complete life cycle of the end product. Furthermore, the GHG emissions quantified should be contextualized within the specific years of 2003, 2006, 2008, and 2010 to maintain temporal accuracy. If the user's assessment period lies outside these timeframes, additional data or assumptions may be necessary to extrapolate the results to the present.
