A Method For Uncertainty Managementin Life Cycle Assessment Studies –A Tiered-Hybrid Case Study Of An Irish Construction Project, Deidre Wolff
Doctoral
Life Cycle Assessment (LCA) quantifies the potential environmental impact of a product system throughout its life cycle from raw material extraction, production, manufacture, use and maintenance through to final disposal. The results from LCA studies are often used to support decision-making processes andpolicy development. LCA is conducted in four iterative steps, beingGoal and Scope definition, Life Cycle InventoryAnalysis (LCI), Life Cycle Impact Assessment (LCIA), andInterpretation. The guidelines for each step are provided in the International Organization for Standardization (ISO) standards, ISO 14040:2006 and 14044:2006. Uncertainty arises in all steps of an LCA,yet the propagation and reporting of these uncertainties is …
