Document Summary

Life cycle interpretation: interpretation: interpret the results analyzed through phases 1, 2, and 3. Analyze and summarize the life cycle inventory and impact analysis results to help determine significance issues. Key steps for lca interpretation: completeness check iso 14040;14044 mandatory, consistency check iso 14040;14044 mandatory, contribution analysis iso 14040;14044 mandatory, sensitivity analysis iso 14040;14044 mandatory, data quality check optional. Ensure that all relevant information and data needed for the interpretation are available and complete for satisfying the goal and scope of the lca. (iso 2006) Attempts to determine whether the assumptions, methods, models and data are consistent either along a product"s life cycle or between several options. (iso. The contribution of each process in each life cycle stages or groups of processes to the total result are examined. (iso 2006) Determine the influence of variations in assumptions, methods and data on lca results. The results are compared based on certain given assumptions or altered assumptions.
