The hardest part of CBAM preparation is not calculation — it is keeping the process together

When supplier inputs, calculation logic and supporting evidence live in different places, teams face the same operational pressure every declaration cycle.

Supplier data stays outside the flow

Emission inputs scatter across email and spreadsheets — gaps are often discovered only as the declaration window approaches.

Calculation logic must be traceable

Direct and indirect allocation, electricity footprints, assumptions and default value comparisons require an auditable methodology trail.

Evidence files must be ready before the deadline

When supplier declarations, supporting documents and methodology notes are not assembled in one review file, teams must rebuild the process under pressure.

CBAM workflow

A six-step CBAM workflow under control

From scope assessment to continuous tracking, the full preparation path is structured around how teams actually work.

01
Assess — Scope & exposure
Define CBAM scope, product coverage, supplier risk and data gaps before the reporting cycle starts.
Product capability · Scope mapping, CN/GTIP coverage checks, supplier risk overview
02
Collect — Supplier data intake
Open controlled supplier access and gather emissions, production, electricity, fuel, process and evidence data in structured requests.
Product capability · Supplier portal, data request workflows, evidence upload, completeness tracking
03
Calculate — Embedded emissions calculation
Run product-level embedded emissions, direct/indirect allocation and electricity footprint from validated inputs.
Product capability · CBAM Calculation Engine, default value comparison, methodology audit trail
04
Evidence — Review-ready file
Compile supplier declarations, documents, quality notes, assumptions and methodology into one structured evidence file.
Product capability · Evidence pack builder, document library, quality flags, methodology notes
05
Report — Declaration preparation
Prepare declaration-ready CBAM output for importers, verifiers or internal sign-off.
Product capability · Declaration export, importer-ready format, verifier briefing pack
06
Monitor — Continuous tracking
Track missing suppliers, weak data quality, upcoming periods and action queues before they become declaration risk.
Product capability · Executive dashboard, gap tracker, deadline alerts, supplier status overview

Supplier data intake

Move supplier data into a controlled intake flow

Replace inbox and spreadsheet tracking with role-based supplier access, data request flows, evidence upload steps and completeness visibility.

Role-based supplier access with controlled permissions
Data request workflows by product, installation and period
Evidence upload with document validation
Missing-data visibility before declaration deadlines
Completeness tracking across supplier responses

Embedded emissions calculation

Run calculations with a methodology audit trail

Model embedded emissions with traceable logic; direct and indirect allocation, electricity footprints, assumptions and default value comparisons held in the same methodology audit trail.

Embedded emissions by product and installation
Direct and indirect emissions with explicit allocation logic
Electricity footprint and emission factor management
Default value comparison with assumption documentation
Methodology audit trail for every calculation step

FAQ

Frequently asked questions about CBAM Calculation Engine

Does Arvenza guarantee CBAM declarations?

No. Arvenza does not guarantee compliance outcomes. The platform helps structure supplier data, calculations and evidence for CBAM preparation — your team remains responsible for declaration decisions.

Can suppliers enter data directly?

Yes. Controlled supplier access, structured data requests and evidence upload are built into the intake workflow — reducing manual follow-up for compliance teams.

Is calculation methodology traceable?

Yes. Methodology notes, assumptions and audit trail are structured within the calculation workflow to support internal review and validation.

Can evidence files be shared with external stakeholders?

Yes. Outputs can be prepared for importers, internal teams or verifier briefing as structured evidence packs — not ad hoc document folders.
