LCA Methodology

This paper describes the incorporation of an independent review process into a life-cycle inventory (LCI) study. The peer review process was the first application of the three-stage review of an LCI. The three stages are: Review of the Goal and Scope Definition, performed when the study plan has been established; Review of the Data-Gathering Methodology, performed after the data have been collected; and Review of the Final Report, performed after the draft report has been written. The purpose, process, and benefits of the review are discussed. Examples of benefits include the incorporation of a proccess to select ancillary materials for inclusion in the study, and a sensitive analysis rationale.
