Our car maker customer in Sanand wants our carbon data. What should an ancillary unit send?
Start with Scope 1 and 2 for your plant, per year, with energy use by source and production volume. Then, if asked, a per-part figure that adds your share of plant emissions to the main materials by weight. Car makers mostly want consistency and a method they can check.
First request
- Scope 1: fuel for furnaces, DG sets, forklifts.
- Scope 2: electricity, with any solar shown separately.
- Production in parts or tonnes for intensity.
Per-part request
- Plant emissions allocated by weight or machine hours.
- Steel, aluminium or plastic per part times supplier or average factors.
- Packaging, if the customer asks.
Formats
Some OEMs use their own portals or industry data exchanges. Keep one master dataset and map it to each format.
What Senseible does here
Senseible reads your fuel, electricity and purchase documents into dated, fingerprinted records, so the figure you send a buyer can be traced to its source.
