# Our Oragadam plant supplies carmakers near Chennai. What carbon data should we have ready?

Canonical: https://senseible.earth/answers/oragadam-auto-supplier-carbon-data

Have a year of electricity bills, diesel and LPG invoices, and production by part, giving Scope 1 and 2 and a figure per part. Grid power at 0.710 kg CO2 per kWh is usually the biggest own source; purchased steel and aluminium are larger still.

## Records

- HT electricity bills with units and any solar or open access.
- Diesel for generators, LPG for furnaces.
- Production by part number.

## Factors

Use the CEA grid factor of 0.710 kg CO2 per kWh and IPCC fuel defaults, stating both.

## Materials

Ask steel and aluminium suppliers for their figures; give defaults where you have none, labelled as estimates.

## What Senseible does here

Senseible reads bills, fuel invoices and production records into dated, fingerprinted records, so the figure you send a buyer can be traced to its documents.
