A ProoV case study · educational project, not employment
Built a battery-passport compliance package for a single cell end to end: classified regulated fields, designed access tiers for public, legitimate-interest, and restricted views, and traced remaining gaps to the supplier tier most likely to own them. Also ran a working carbon-footprint calculation and used it to identify raw materials as the dominant emissions stage, showing practical compliance and analytical judgment.

What stood out6
- Ran an actual carbon-footprint calculation and correctly identified raw materials as the dominant stage at 48.05 kg CO2e out of 74.05 kg CO2e per kWh.
- Made a coherent public / legitimate-interest / restricted split, including defensible treatment of carbon-by-stage and due-diligence data.
- Attributed remaining gaps to supplier tiers in a way that reflects the chain structure, especially for recycled-content and refiner-owned inputs.
- Drafted supplier requests with named fields, regulatory basis, and deadlines rather than generic data asks.
- Leakage-Free Carbon Accounting
- Regulatory Judgment Under Ambiguity
