Supply Chain

Multi-Tier Supplier Management

The supply chain is the most demanding dimension of CBAM compliance. The single module that reduces this process to one flow with invitation links, a portal wizard, a multi-tier structure and automated reminders.

The Market Difference

Other Platforms Stop at Tier 1.
We Go to the End of the Chain.

To calculate a product's embedded emissions correctly, CBAM regulation requires data from the entire supply chain. Other platforms are limited to Tier 1. Carbonaz goes to the end of the chain.

Regulatory Requirement

At Least 80% of Precursor Emissions
Must Be Real Data

Going to the end of the chain is not an aesthetic choice; it is a threshold imposed by CBAM regulation. If this threshold is not met, the cost rises directly.

The CBAM Rule

CBAM regulation requires that at least 80% of precursor data in the embedded emissions calculation be based on real data obtained from the supplier. This threshold requires collecting data not only from the direct supplier but from the entire chain.

Real supplier data80% minimum
Default value (permitted)20% maximum

The Cost of Missing Data

Using default values leads to a mark-up penalty. The increase applied to the calculated emissions grows every year and is reflected directly in the CBAM certificate cost.

2026+%10
2027+%20
2028 and beyond+%30

Carbonaz goes to the end of the chain. It helps you reach the 80% threshold and avoid mark-up penalties.

Portal Wizard

6 Steps for the Supplier. Automatic Tracking for the Producer.

Your supplier needs no technical knowledge or CBAM expertise. They click the invitation link, follow the 6-step wizard and enter their data. The system guides both of you automatically.

Supplier

The supplier completes their own company profile. Tax number, address and authorised contact details.

04

Precursor Products

They select which intermediate products they supply to the producer. CN code and quantity entry.

05

Emission Data

Supplier

They enter Scope 1, Scope 2 and precursor emission data, or upload a file.

06

Producer Approval

Producer

The submitted data is reviewed by the producer, then approved or sent back for revision.

It cuts the supplier's average process to 15 minutes. With automated reminders, dual-role support and a data approval flow, the producer's tracking burden drops to zero.
