Use advice for data set When utilizing this LCA data set, users should consider the specificity of the regional data sources and technological standards of China in 2013. Ensure the context of use aligns with that of the Chinese industry practices at the time. The primary aluminum (PA) and secondary aluminum (SA) data inputs must be sourced from reputable statistical data sources or from scientific literature. Background data should be referenced from the CAS RCEES 2018 database or similar Chinese localized LCA databases, ensuring that the data matches the methodology and geographical applicability of the study. Pay particular attention to methodological aspects such as system boundaries, allocation methods, and inclusion or exclusion of recycling processes where applicable.
