# Our Puebla plant supplies a German carmaker. What will their carbon request look like?

Canonical: https://senseible.earth/answers/puebla-auto-supplier-oem-carbon-request

Expect a request for Scope 1 and 2 by plant, a footprint for each part number, the share of renewable electricity and a reduction plan. Data often goes through the carmaker's own supplier portal, so keep the figures and their sources in one place.

## What they ask

- Plant Scope 1 and 2 with method and factors.
- Product footprints, often cradle to gate.
- Renewable electricity share and certificates.

## Preparing

Collect a year of electricity bills, fuel invoices and production by part number. Material emissions need supplier data or defaults.

## Consistency

Use the same period and factors across every buyer portal, so the numbers match when compared.

## 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.
