CBAM software automates the three heaviest compliance tasks that Regulation (EU) 2023/956 places on EU importers in the definitive phase: collecting per-installation emissions data from suppliers, calculating embedded emissions, and preparing the annual declaration. This section of cbamguide.com contains 7 pages: one comparison roundup and 6 independent vendor reviews covering Coolset, Cbamboo, CarbonChain, Kolum, Greenly, and Dubrink. Each review applies the same evaluation framework, so findings are directly comparable across vendors.
The workload that drives software demand in 2026 is supplier data collection, not certificate purchasing. The first annual CBAM declaration is due September 30, 2027, and covers every tonne of covered goods imported during calendar year 2026. That declaration requires embedded emissions figures per production installation, supported by either verified actual data or the default values of Implementing Regulation (EU) 2025/2621, which carry punitive mark-ups. An importer sourcing steel, aluminium, or fertilizers from 10 or more installations must request, track, validate, and archive emissions data from each one, then keep the records ready for verification. The CBAM declaration and CBAM reporting guides explain those obligations in full. The software reviewed here exists to industrialize them.
Certificate economics add a second reason to build tooling now. The official CBAM certificate price for Q2 2026 is €75.28 per tonne CO₂e, published July 6, 2026 by the European Commission, and certificate sales open February 1, 2027. The 2026 CBAM factor of 2.5% keeps first-year net costs low, but the factor rises every year until it reaches 100% in 2034, so a cost forecast built in 2026 shapes sourcing decisions for the next 8 years. The 50-tonne de minimis threshold exempts roughly 90% of importers (about 182,000 companies) from CBAM entirely. The remaining importers, whose goods carry more than 99% of covered embedded emissions, are the audience for every review in this section.
CBAM software platforms cluster around four functions, listed below.
- Supplier data collection: structured emissions data requests sent to non-EU installations, with response tracking and automated reminders aligned to the CBAM monitoring and reporting methodology.
- Emissions calculation: conversion of supplier data, or of the default values where actual data is missing, into the embedded emissions totals the declaration requires.
- Certificate cost forecasting: projection of certificate spend across the 2026 to 2034 CBAM factor schedule at the current EU ETS-linked price.
- Declaration preparation: assembly of import records, emissions data, and audit trails into declaration-ready format. The declaration itself is always filed by the authorized declarant through the CBAM Registry; software prepares the data that goes into it.

CBAM Software or Free CBAM Tools: Which Do You Need?
Free tools answer scoping and cost questions; paid software manages recurring supplier data workflows. An importer who needs to confirm product coverage can check any Annex I code with the free CBAM CN Code Lookup, project certificate costs through 2034 with the CBAM Cost Calculator, and follow the official quarterly certificate price with the CBAM Certificate Price Tracker. All three run in the browser at no cost and with no registration.
Paid software becomes worth evaluating when the recurring work starts: more than 10 suppliers of covered goods, imports across multiple sectors such as steel, cement, and aluminium, or internal audit requirements that demand traceability from every declared figure back to its source document. No regulation requires software. Every obligation described in the EU CBAM guide can be met with spreadsheets and the free tools, at the cost of manual effort and higher error risk as supplier counts grow.
How We Evaluate CBAM Software
cbamguide.com is an independent editorial site with no commercial relationship to any vendor reviewed in this section. The 5 rules below govern every review.
- No affiliate or referral links. Vendor links point to plain vendor homepages only. No review link carries tracking parameters or earns a commission.
- No paid placements. Vendors cannot buy inclusion, ranking position, or wording changes.
- Verified facts only. Every feature and pricing statement is checked against the vendor's own site, archived versions of it, or a named third-party source. Claims we cannot verify are hedged or omitted.
- Dated pricing. Vendor pricing changes frequently, so every price statement carries an "as of July 2026" marker. Coolset, for example, publishes no price list and quotes per customer, as of July 2026.
- No invented ratings. We publish no star scores, user quotes, or customer counts that we cannot trace to a source.
Reviews are updated when vendor products change. The Coolset review, for example, documents that the company's dedicated CBAM product page now redirects to its homepage as of July 2026, a material change for any buyer shortlisting it for CBAM work.
