How to choose CBAM software
Since 1 January 2026, EU importers of iron and steel, aluminium, cement, fertilisers, hydrogen and electricity must declare the embedded emissions of these goods under the Carbon Border Adjustment Mechanism (CBAM). Choosing CBAM software means choosing how those emissions are calculated, verified and declared. This checklist covers what to compare.
Start with your CBAM role
CBAM software needs differ by role. Know which of these you are before comparing tools.
EU importers
Identify CBAM-covered imports, collect actual emissions from suppliers, fall back to default values only where needed, prepare the CBAM declaration and plan certificate costs.
Enzera Importer Suite →Non-EU manufacturers
Calculate installation-specific embedded emissions, allocate them across products, maintain a monitoring plan and deliver verification-ready data to EU customers.
Enzera Supplier Suite →Accredited verifiers
Review structured evidence instead of folders of spreadsheets, record findings and issue the verification report.
Enzera Verifier Suite →CBAM consultants
Work across many client workspaces with permissions the client controls and a full audit log per client.
Enzera Consultant Suite →10 criteria for comparing CBAM software
Use these questions in vendor demos. The last column shows how Enzera handles each point.
| Criterion | Why it matters | What to ask | Enzera |
|---|---|---|---|
| 1. Regulatory methodology | Embedded emissions must be calculated the way the EU rules prescribe, and the rules have been updated since the transitional period. | Which regulations and implementing acts does the calculation follow, and how quickly are updates applied? | Implements Regulation (EU) 2023/956 and implementing regulations EU 2025/2547, 2025/2546, 2025/2620 and 2025/2621. |
| 2. Sector coverage | Steel, aluminium, cement, fertilisers and hydrogen each have different production routes and system boundaries. | Are all CBAM sectors and their production routes supported, or only a generic emission-factor approach? | Specific embedded emissions (SEE) calculations across seven industrial sectors. |
| 3. Actual emissions vs default values | Default values are set conservatively, so relying on them usually means a higher CBAM cost. | Can the tool calculate installation-specific actual emissions, and track where defaults are still used? | Calculates actual SEE for suppliers; importers see which import lines still rely on defaults. |
| 4. Multi-product allocation | Real plants share fuels, meters and precursors between several products. This is where spreadsheets usually break. | How are shared energy meters, internal precursor transfers and by-products allocated? | Allocation wizard and visual Installation Modeler for multi-route installations and precursor chains. |
| 5. Monitoring plan | The monitoring plan defines what data must be collected and is the starting point for verification. | Is the monitoring plan generated from the installation configuration, or written separately by hand? | Monitoring plan generated per EU 2025/2547 Annex IV from the allocation configuration. |
| 6. Supplier data exchange | Importers depend on supplier data; suppliers receive requests from many customers. | Can importers send structured requests and receive verified values directly, without email and re-typing? | Importer emission inquiries; supplier responses link to the importer’s declaration. |
| 7. Verification readiness | Emissions data has to be verified by an accredited verifier, who needs a reliable audit trail. | Is there a period lock, an audit trail and a way for the verifier to review the data inside the tool? | Readiness checks before lock, SHA-256 hash of calculation inputs, structured data room and verifier sign-off. |
| 8. Declaration preparation | Importers must turn the collected data into the CBAM declaration without errors. | Does the tool validate the declaration and export it in the format required by the EU portal? | Declaration workspace with validation checks and XML export. |
| 9. Cost forecasting | The CBAM cost rises as free allocation under the EU ETS is phased out up to 2034. | Can you model future CBAM cost under different carbon price and supplier scenarios? | CBAM exposure forecasting 2026–2034 with price and supplier-switching scenarios. |
| 10. Trying before buying | You should be able to check the calculation logic against your own numbers before committing. | Is there a free calculator, trial or demo with your own data? | Free importer and supplier calculators with no account, using the same logic as the platform. |
Spreadsheets, carbon accounting tools or dedicated CBAM software?
Most companies compare four kinds of solution. Each fits a different level of complexity.
Spreadsheets
Good for: Cheap and flexible for a single product with simple data.
Limits: Error-prone for multi-product allocation, no audit trail or locking, hard to hand over to a verifier.
General carbon accounting / ESG platforms
Good for: Useful for corporate footprints (Scope 1–3) and ESG reporting.
Limits: Typically built around corporate emission factors rather than the installation-level CBAM methodology, monitoring plan and verification workflow.
Customs and trade compliance tools
Good for: Strong on customs data, CN codes and import declarations.
Limits: Typically depend on emissions data calculated elsewhere; little support for the supplier side of CBAM.
Dedicated CBAM software
Good for: Built for the CBAM methodology end to end: calculation, allocation, monitoring plan, verification and declaration.
Limits: Narrower scope: it does not replace a full ESG reporting suite.
Where Enzera fits
Enzera CBAM Connect is dedicated CBAM software built for complex industrial production: integrated steel mills, cement plants, aluminium smelters and fertiliser complexes with several products, shared meters and precursor chains. Suppliers, importers, verifiers and consultants work in one connected platform, so verified supplier data flows directly into the importer’s declaration.
If you only need a corporate carbon footprint, a general carbon accounting tool may suit you better. If you import only small quantities of CBAM goods, check first whether you are above the CBAM threshold at all; our free calculators are a quick way to estimate your exposure.
Choosing CBAM software: FAQ
What should I look for in CBAM software?
Check that it follows the current EU CBAM regulations, calculates installation-specific actual emissions, handles multi-product allocation, generates the monitoring plan, supports supplier data exchange and verification, and prepares the CBAM declaration.
Is a spreadsheet enough for CBAM?
For a single product with simple data, a spreadsheet can work. Installations with several products, shared meters or precursors usually need software that applies the allocation rules consistently and keeps an audit trail for the verifier.
Do importers and suppliers need different CBAM software?
They need different functions. Importers need coverage tracking, supplier inquiries and declarations; suppliers need emissions calculation, allocation, monitoring plans and verification. A connected platform lets the verified supplier data flow directly into the importer’s declaration.
Can I test CBAM software for free?
Enzera’s importer and supplier CBAM calculators are free, need no account and use the same regulatory logic as the full platform.
