Defines the LCA's purpose and the expected product's system boundaries, setting the context for the assessment.

Collects data on the inputs and outputs within the system boundaries to quantify the environmental impacts.

Evaluates the magnitude and significance of the potential environmental impacts of the inventory data.

Analyzes results, assesses the reliability, recommends actions to reduce environmental impacts, and communicates findings.

Ensures methodological rigor and credibility of the LCA study through external expert evaluation.

Determines what processes will be included in the LCA, impacting the comprehensiveness of the study.

The quantitative measure of the system's function which the LCA is based upon, ensuring comparability.

Specifies the type, source, and quality of data needed to make the LCA scientifically sound.

Describes the distribution of inputs or outputs for processes that serve more than one product, ensuring fair impact assignment.

Choosing relevant environmental impact categories to which the LCA results can be assigned, such as global warming potential.

Puts impact category results into a common scale and may assign relative importance to each category for easier interpretation.
