Methods for Life Cycle Inventory of a product

摘要: Abstract Methods for Life Cycle Inventory (LCI) compilation are reviewed and compared. In total, six methods distinguished. They LCI computation using process flow diagram; matrix expression of product system; input–output (IO) based LCI; three different forms hybrid analysis: the tiered analysis, IO-based integrated analysis. Theory principles these presented a numerical example, evaluated with regard to data requirements, uncertainty source data, upstream system boundary, technological geographical available analytical tools, time labour intensity, simplicity application, required computational tools software tools. Compliance ISO standards is discussed. Finally, conclusions drawn, combined view on future outlook inventory building methods.
