Tier 1 // LITHIUM RECORD
A practical guide to lithium battery carbon footprint methodology, benchmarks, verifier review, and permanent reporting URLs.
A lithium battery carbon footprint begins before the cell factory. The relevant record should capture extraction, concentration, refining, conversion, transport, electricity inputs, reagent use, water context, allocation rules, and product-specific output such as lithium carbonate equivalent.
Hard-rock spodumene routes are often discussed in the 5–8 tCO₂ per tonne LCE range, while brine routes are often discussed in the 2–4 tCO₂ per tonne LCE range. Those ranges are directional only; the compliant value depends on the actual mine, energy mix, processing route, cut-off rules, and verifier-reviewed methodology.
NMC, LFP, and NCA cell supply chains rely on different cathode pathways and therefore ask different questions of lithium suppliers. Lithium Record focuses on the feedstock evidence layer rather than pretending one battery-level benchmark fits every chemistry.
An ISO 14065 or equivalent assurance workflow reviews the calculation boundary, data quality, emission factors, allocation logic, and report consistency. Lithium Record then converts the verified figure into a persistent record that can be referenced by OEM and battery passport systems.
Every page in this static layer points back to the same operating premise: lithium compliance evidence needs a stable, readable, citation-friendly URL rather than a disposable file export.
| Record field | Why it matters |
|---|---|
| kgCO₂/kg LCE | Translates site evidence into OEM carbon-footprint workflows. |
| GPS and extraction route | Hardens provenance and supports due-diligence review. |
| Verifier signature | Shows independent assurance status and review trail. |
| SHA-256 hash | Connects documents, metadata, and permanent record identity. |
Lithium Record content is written as technical infrastructure guidance, not legal advice. Formal compliance decisions should be reviewed with qualified counsel and accredited verifiers.
| Reference | Relevance |
|---|---|
| Regulation (EU) 2023/1542 | EU batteries and waste batteries regulation establishing sustainability, performance, safety, information, and lifecycle obligations. |
| Battery Passport Content Guidance | Practical guidance on Article 77 battery passport scope, responsible operators, and February 18, 2027 readiness. |
