Product GHG inventory by life-cycle stage
Measurement answer
What this metric measures
Reports product inventory results separately for material acquisition and preprocessing, production, distribution and storage, use, and end-of-life.
Specification

- Result format
- Structured table
- Unit
- Structured table — see field-level units

- Metric
Reporting boundary
Attributable processes inside the declared product system boundary, preserving raw material acquisition and preprocessing, production, distribution and storage, use, and end of life as separate stages, with excluded processes disclosed.

Evidence and status sources
Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

- Product and unit of analysis
- Cradle-to-grave or justified cradle-to-gate boundary
- Reporting period and reference flow
- Included life-cycle stages and attributable processes
- Data sources, allocation, data quality and uncertainty
- Excluded processes and limitations
Record-specific limitations
- Combine only observations with compatible products, units of analysis, life-cycle boundaries, periods, gases and methods.
- Physical inventory results remain separate from offsets, avoided emissions and comparative claims.
Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.
Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
