2. What is LCA? "compilation and evaluation of the inputs, outputs and potential environmental impacts of a product system throughout its life cycle".(source :ISO 14040)

5. LIFE CYCLE ASSESSMENT FRAMEWORK Goal and Scope definition  specifying the reason for conducting the study  intended use of study results  intended audience  system boundaries  data requirements  study limitations.

6. Life Cycle Inventory (LCI): collecting, validating and aggregating input and output data to quantify material use, energy use, environmental discharges, and waste associated with each life cycle stage.

7. CONTD….. Life Cycle Impact Assessment (LCIA): using impact categories, category indicators, characterization models, equivalency factors, and weighting values to translate an inventory into potential impact on human health and the environment.

8. Life Cycle Impact Assessment (LCIA)

9. CONTD… Interpretation assessing whether results are in line with project goals, providing an unbiased summary of results, defining significant impacts, and recommending methods for reducing material use and environmental burdens.
