# What carbon data do OEMs ask auto part suppliers in Bawal for?

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

Carmakers ask for Scope 1 and 2 emissions, often per part or per kg, plus renewable share and a reduction plan. Some ask for material footprints for steel, aluminium and plastic parts. Twelve months of power and fuel bills and part-wise production are the starting point.

## Usually asked

- Scope 1 and 2 totals and per part.
- Share of renewable electricity.
- Reduction targets.

## For material-heavy parts

Steel, aluminium and plastic suppliers' figures, or labelled factors.

## Tip

Use machine hours or weight to split plant energy across part numbers.

## 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.
