Inventory Analysis
Collects data on the inputs and outputs within the system boundaries to quantify the environmental impacts.
Impact Category Selection
Choosing relevant environmental impact categories to which the LCA results can be assigned, such as global warming potential.
System Boundary Selection
Determines what processes will be included in the LCA, impacting the comprehensiveness of the study.
Impact Assessment
Evaluates the magnitude and significance of the potential environmental impacts of the inventory data.
Sensitivity Analysis
Evaluates how changes in the data and assumptions affect the outcome of the LCA, assisting in understanding the robustness of the results.
Interpretation
Analyzes results, assesses the reliability, recommends actions to reduce environmental impacts, and communicates findings.
Data Quality Requirements
Specifies the type, source, and quality of data needed to make the LCA scientifically sound.
Allocation Procedures
Describes the distribution of inputs or outputs for processes that serve more than one product, ensuring fair impact assignment.
Goal and Scope Definition
Defines the LCA's purpose and the expected product's system boundaries, setting the context for the assessment.
Functional Unit Definition
The quantitative measure of the system's function which the LCA is based upon, ensuring comparability.
Normalization and Weighting
Puts impact category results into a common scale and may assign relative importance to each category for easier interpretation.
Critical Review
Ensures methodological rigor and credibility of the LCA study through external expert evaluation.
