Life cycle interpretation is one of the four phases identified in the ISO 14040 and the ISO 14044 standards (ISO 2006a,b). The interpretation phase requires a critical assessment of the result of an LCA study, encompassing life cycle inventory (LCI) and life cycle impact assessment (LCIA) phases according to the goal and scope of the study. The importance of a proper interpretation of results of an LCA study is recognized by relevant standards, guides and research articles. The ISO 14044 specifies that interpretation comprises the following elements: (i) the identification of the significant issues based on the results of the LCI and LCIA phases of LCA; (ii) an evaluation that considers completeness, sensitivity and consistency checks; and (iii) the provision of conclusions, limitations and recommendations (ISO 2006b).
