The ISO 14067 LCA phase for compiling and quantifying product-system inputs and outputs.
Life cycle inventory analysis compiles and quantifies inputs and outputs for a product across its life cycle. It is not the final interpretation; it is the structured data foundation used by impact assessment and footprint calculation.
This page follows ISO 14067:2018. Inventory quality, completeness, allocation, and data-source choices strongly shape the reliability of a product carbon-footprint result.
ISO 14067:2018 - Greenhouse gases — Carbon footprint of products
phase of life cycle assessment (3.1.4.3) involving the compilation and quantification of inputs and outputs for a product (3.1.3.1) throughout its life cycle (3.1.4.2)
Reference: 3.1.4.4
This term originates in ISO 14067:2018 and/or ISO 14044 LCA methodology. It is used in EU product regulation — particularly under the EU Battery Regulation (PEF method for carbon footprint) and ESPR (environmental footprint) — because both regulations require lifecycle-based quantification of environmental impacts. Practitioners applying these regulations should be familiar with these LCA/PEF concepts to correctly scope, conduct, and verify product-level environmental assessments.
Implementation records should capture the input flow, output flow, unit process, data-quality record, product-system link, allocation rule, source dataset, quantity, and completeness check.
Life cycle inventory analysis is a footprint-data foundation control: the evidence consequence is that inputs and outputs remain traceable to processes and data-quality rules before impact indicators or CO2e results are calculated.
