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

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.

• Mexico grid factor
• Mexico carbon tax and CBAM
• Buyer questionnaire formats
