Carbon evidence changes. Version control keeps old lithium carbon files reviewable instead of replacing the evidence that supported an earlier battery decision. 1 2
This spoke belongs to the Lithium Carbon Footprint Evidence pillar at /lithium-carbon-footprint-evidence/.
Version control as evidence hygiene
A lithium supplier may revise an emissions factor, update a process route, correct a transport distance, change a reporting period, or issue a new calculation extract. If the old file disappears, the audit trail weakens. Lithium Record should treat each material change as a new evidence version with its own timestamp, URL, hash, and note explaining the relationship to the prior file.
What the version note should say
A useful version note states whether the change is a replacement, correction, annual update, methodology shift, or supplemental file. It should not hide uncertainty. If the customer uploads a corrected declaration, the page can identify it as customer-uploaded and hash it. The platform should not decide whether the correction is legally adequate.
Internal link value
Version-control pages should link back to Article 7 evidence, LCA source files, supplier carbon declarations, and transport or energy records. This creates a traceable chain from final carbon statement to each source file version.
