Supplier carbon declarations are often the first carbon file a battery team receives for lithium inputs. The declaration should be preserved exactly, not turned into a broader claim by the vault. 1 2
This spoke belongs to the Lithium Carbon Footprint Evidence pillar at /lithium-carbon-footprint-evidence/.
Declaration capture
A supplier declaration can identify the lithium product, production site, reporting period, calculation boundary, unit, methodology reference, and responsible issuer. Lithium Record can host that declaration and expose the hash. The page should state whether supporting files exist or whether the declaration is the only uploaded evidence. That distinction matters because a declaration without source data is not the same as a complete evidence package.
Downstream use
Battery manufacturers may use supplier declarations as inputs to purchased-goods emissions or battery carbon-footprint work. The vault page should not rephrase the supplier claim as Lithium Record’s claim. It should attribute the statement to the document issuer and keep the file available for review.
Change management
Supplier declarations change when methodology, energy data, process data, or reporting periods change. Each new declaration should be added as a separate record or version. A stable archive prevents the evidence trail from losing the document that supported an earlier customer decision.
