[AUTOMOTIVE SECTOR]

The carbon footprint of every vehicle, from steel to the assembly line.

CarbonOS combines the bill of materials, supplier data and plant energy to calculate the footprint of every model and every part. The same data serves Brazil’s MOVER programme, your Scope 1, 2 and 3 inventory and buyers in Europe.

[HOW IT WORKS]

From bill of materials to the footprint of every vehicle, in one pipeline.

CarbonOS reads the bill of materials (BOM) and purchasing data from your ERP, collects part footprints from suppliers and adds plant energy and fuels. Every figure traces back to the part, the supplier and the emission factor used.

MOVER: registering the footprint of vehicles sold in Brazil.

Brazil’s Decree 12,435/2025 calls for registering the carbon inventory of the plants and the footprint of vehicles sold in the country. From 1 January 2027, mandatory cradle-to-grave footprint requirements, set by Brazil’s industry ministry (MDIC), apply.

FROM 18 FEB 2027

Digital passport for electric vehicle batteries in the EU.

Under Regulation (EU) 2023/1542, every electric vehicle battery placed on the EU market needs a digital passport. The battery carbon footprint declaration applies 12 months after the delegated act that sets the calculation method.

PROPOSED FOR 2028

CBAM may reach steel and aluminium parts.

The EU is negotiating an extension of CBAM to downstream steel and aluminium products, including vehicle parts, from 1 January 2028. European buyers will ask for the embedded emissions of each part.

Status as of November 2026. EU rules under negotiation may change.

[WHAT YOU GET]

Vehicle footprints, your supply chain and reports in one platform.

Four CarbonOS agents do the work: Carbon Intelligence calculates vehicle footprints and the inventory, Supply Chain collects and checks supplier data, Proof Engine keeps the trail behind every figure, and Compliance Hub prepares MOVER, SBCE and CBAM reports.

How is the carbon footprint of a vehicle calculated?

From the bill of materials: each part and material (steel, aluminium, plastics, battery) gets the footprint reported by its supplier or an emission factor whose source and version are recorded. Plant energy and fuels, painting, assembly and logistics are added; for a cradle-to-grave footprint, the use phase and end of life are included too. CarbonOS follows ISO 14067 for product footprints and the GHG Protocol for the company inventory.

What does MOVER require on carbon footprint?

Under Decree 12,435/2025, which regulates Brazil’s MOVER programme, manufacturers and importers declare, by 31 December 2026, the registration of the carbon inventory of their source plants and of the carbon footprint of vehicles sold in Brazil. From 1 January 2027, mandatory cradle-to-grave carbon footprint requirements apply, as set by Brazil’s industry ministry (MDIC). Check the details of your own registration with your legal team.

How does supplier data come in?

Supply Chain gathers the part footprints reported by suppliers, checks the data for consistency and separates primary data from estimates. Where a supplier has no data yet, an average emission factor with a recorded source is used, and the report shows how much each estimate weighs in the total.

Does CarbonOS connect to a carmaker’s ERP?

Yes. Signal Ingest reads bill of materials, purchasing and production data from the ERP (SAP, TOTVS and others) through an API, a database connection or file import, with read-only access. Nothing has to be re-keyed.

Which EU rules affect the automotive supply chain?

Three fronts: the digital passport for electric vehicle batteries, mandatory from 18 February 2027 under Regulation (EU) 2023/1542, which also provides for a battery carbon footprint declaration; the proposal to extend CBAM to steel and aluminium parts from 2028, still under negotiation; and data requests from customers reporting under the CSRD.

What do you need to get started?

An export of the bill of materials and purchasing data, or access to the ERP, plus energy bills and fuel records for the plants. In a demo, Carbonova shows how this data becomes a footprint per vehicle and per part, and what connecting your ERP involves.
