– Inventory analysis: An inventory of the system’s input and output flows is carried out using a combination of primary and secondary data collected for each of the system’s processes.
– Impact assessment: The aim of this phase is to convert the inventory data into environmental impacts, using characterization factors derived from an impact assessment method.
– Interpretation: This phase includes an assessment of data quality, a contribution analysis, a sensitivity analysis, a discussion of limitations, as well as suggestions for improvement and possible updating of the LCA.
