3. LCSA Flashcards
Defenition of Goal and Scope
Defines the questions being asked and the scope of the activated that will be undertaken to answer the questions, defines the boundaries of the system. The following items should be considered and clearly described:
- The functions of the product system
- The functional unit which is a fixed reference point for the environmental assessment
- The product system to be studied
- The product system boundaries
What is the functional unit
- “A quantified description of the performance requirements that the product system fulfils”
- Enables comparison of two different product systems
- Statement regarding quantity, quality and duration of function required
Inventory Analysis
Involves data collection and calculation procedure to quantify relevant inputs and outputs of a product system. Interpretations may be draw depending on the goal and scope. Input to lice cycle impact assessment.
Method:
1. Develop system boundaries and classify events in the products life cycle
2. Determine all mass and energy inputs and outputs
3. Collect the relevant information
4. Make assumption for missing data
5. Establish material and energy for each stage and event
Impact Assesment
Aimed at evaluating the significance of potential environmental impacts using the results of the inventory analysis. Involves associating inventory data with specific environmental impacts and attempting to understand those impacts. Level of detail determined in goal & scope.
Interpretation
Where the findings from inventory analysis and the impact assessment are combined together. Should be consistent with the defined goal and scope in order to reach conclusions and recommendations.
LCSA
A method for assessing the sustainability of products and processes. Has a more broadened scope than LCA to include consideration for the three-pillar model of sustainability.
E-LCA, LCC, S-LCA = LCSA
