A ProoV case study · educational project, not employment
Built a three-part battery passport compliance package for a single cell: computed the carbon footprint from a bill of materials, split regulated fields into public / legitimate-interest / restricted passport views, and traced remaining gaps to the supplier tier that owns them. Also drafted two supplier-ready requests that specify the exact field, regulatory basis, format, and deadline needed to close the highest-priority gaps.

What stood out6
- Computed the cell footprint in code and reported a stage breakdown plus total of 74.05 kg CO2e per kWh.
- Made a defensible interpretation that upstream raw materials dominate the footprint, not the cell plant alone.
- Separated passport fields into public, legitimate-interest, and restricted views rather than treating access as one-size-fits-all.
- Drafted supplier requests that name the field, cite Article 77, specify batch-level format, and set a deadline.
- Leakage-Free Compliance Modeling
- Honest Regulatory Judgment Under Ambiguity
