国际铝协：2018年铝工业碳足迹技术支持文件报告（英文版）

The goal of this guidance is to calculate the potential contribution to global warming of the production of one (1) tonne of cast primary aluminium metal from aluminium containing ore(s). Its climate change impact, expressed as carbon dioxide equivalents (CO2e), is the summation of all significant GHG emissions and removals over the product’s partial life cycle. A cradle-to-gate system of primary (or electrolytic) aluminium production is shown in Annex B. It includes bauxite mining, alumin
