Why Life Cycle Assessment matters
LCA matters because environmental impact is rarely where people assume it is. A decision that looks greener at one stage can shift a larger burden to another, for example a cleaner manufacturing step fed by a carbon-intensive material. By measuring the whole life cycle rather than a single stage, LCA reveals these trade-offs and stops companies optimising in the wrong place.
It is also the methodological engine underneath almost every modern environmental requirement. Product carbon footprints, EPDs, EU Battery Regulation declarations, and Digital Product Passports are all, at root, LCA outputs.
The four phases of an LCA
ISO 14040/14044 define four phases:
Goal and scope definition: what is being assessed, why, the functional unit, and the system boundary
Life cycle inventory (LCI): collecting data on every input and output, including materials, energy, emissions, and waste
Life cycle impact assessment (LCIA): translating those flows into impact categories using a method such as EF 3.1
Interpretation: identifying the significant findings, testing their robustness, and drawing conclusions
The phases are iterative, not linear. Interpretation often sends the practitioner back to refine the scope or chase better data.
What makes an LCA defensible
The credibility of an LCA rests on three things: a clearly defined system boundary, the quality of the underlying data, and independent review. A model built on generic averages produces a generic answer; one built on primary supply chain data produces a defensible one. For regulated or customer-facing work, an independent critical review, where a third-party panel checks the method and conclusions, is what allows the result to withstand scrutiny.
Where Life Cycle Assessment is used
LCA underpins regulatory compliance (EU Battery Regulation, CBAM, EPDs, DPPs), product design and eco-design decisions, supplier and procurement comparisons, and corporate Scope 3 reporting. In industrial supply chains such as batteries, critical minerals, and chemicals, it is increasingly the basis on which products are selected, not just reported.
