氧化铝生产2017 Users of this data should note that the PA (Production Allocation) data is sourced from statistical data, while SA (Site Allocation) data mainly comes from literature. It is essential to align the use of this data with corresponding temporal (years of data validity) and geographic (site-specific mining conditions) boundaries. The background data is sourced from the CAS RCEES 2018 database, which is specific to Chinese localization and may need to be adjusted if applied within a different environmental or regulatory context. Methodological considerations such as system boundaries, allocation procedures, and data quality should align with the goal and scope of the intended LCA study.
