Best CBAM Software 2026: 6 Tools Compared for EU Importers

Six CBAM software tools lead the EU importer market in 2026: Coolset, CBAMBOO, CarbonChain, kolum, Greenly, and Dubrink. For most mid-market EU importers, a dedicated CBAM specialist (CBAMBOO or kolum) offers the most direct route to a compliant first declaration, while commodity-heavy enterprises importing steel, aluminium, iron, or fertilizers are better served by CarbonChain. Teams that manage CBAM alongside CSRD, EUDR, or corporate carbon accounting obligations gravitate toward suite platforms such as Coolset and Greenly instead.

The stakes behind this software decision are set by the regulation itself. The definitive phase of the Carbon Border Adjustment Mechanism has been in force since January 1, 2026 under Regulation (EU) 2023/956, as amended by Regulation (EU) 2025/2083. Certificate sales open February 1, 2027, and the first annual CBAM declaration, covering calendar-year 2026 imports, is due September 30, 2027. The official CBAM certificate price stands at €75.28 per tonne CO₂e for Q2 2026, published by the European Commission on July 6, 2026. Every date in that compliance chain is mapped in the CBAM timeline, and every tool in this comparison exists to feed it with clean, verifiable emissions data.

This page is the flagship comparison in the cbamguide.com CBAM software review cluster. It compares scope, target users, pricing transparency, and best-fit scenarios across all six deep-reviewed vendors, then covers adjacent tools, and closes with a software-versus-consultant-versus-DIY decision framework.

The quick verdict for each of the six tools is listed below.

• CBAMBOO: deepest CBAM-only feature set, importer and supplier sides, registry-compatible XML
• CarbonChain: enterprise-grade platform for steel, aluminium, iron, and fertilizer supply chains
• kolum: guided end-to-end EU CBAM workflows for German-speaking and EU mid-market importers
• Coolset: multi-regulation ESG suite; CBAM module status requires direct vendor confirmation as of July 2026
• Greenly: carbon-accounting-first platform for teams treating CBAM as one obligation in a wider sustainability workload
• Dubrink: newer CBAM-focused entrant with limited public documentation; evaluate by demo

CBAM Software Comparison Table (2026)

The table below compares all six CBAM software tools on scope, target user, public pricing, and best-fit use case, based on vendor documentation and primary sources reviewed in July 2026.

Two patterns stand out in this table. First, not one of the six vendors publishes official CBAM pricing on its own website that we could verify as of July 2026, so budget conversations start with a demo request in every case. Second, scope varies more than marketing copy suggests: only CBAMBOO and CarbonChain describe registry-compatible XML output in any detail, and CarbonChain's CBAM case studies and marketing emphasize four of the six covered sectors.

How We Evaluate CBAM Software

cbamguide.com is an independent editorial site: we accept no affiliate commissions, no paid placements, and no sponsored rankings, and every vendor link on this page is a plain homepage link. We do not publish invented review scores, star ratings, or user quotes. Rankings and "best for" calls reflect documented product scope, not commercial relationships.

Our evaluation draws on vendor websites, archived product pages, primary EU legal sources, and clearly attributed third-party reporting. Prices appear only when a vendor publishes them or when a third-party figure can be named and attributed. The seven criteria we score against are listed below.

1. Sector scope match against the six CBAM sectors: iron and steel, cement, aluminium, fertilizers, electricity, and hydrogen
2. Emissions calculation aligned with the methodology rules explained in our CBAM calculation guide, including precursor handling
3. Default value support under Implementing Regulation (EU) 2025/2621, with clear comparison against actual supplier data
4. Supplier data collection workflows that non-EU installations can realistically complete
5. Registry-compatible output for the declaration and surrender process managed through the CBAM Registry
6. Certificate cost forecasting ahead of the February 1, 2027 sales opening
7. Pricing transparency and vendor stability, including funding, team, and certification signals

A tool can score well for one importer profile and poorly for another. A steel trader moving 200,000 tonnes per year and a machine builder importing 400 tonnes of fasteners need different software, which is why each verdict below names its target user.

The 6 Best CBAM Software Tools for 2026

The six tools below are ordered as they appear in the comparison table, and each summary links to a full standalone review with feature, pricing, and company detail.

1. Coolset: ESG Suite With CBAM Data Collection for the Mid-Market

Coolset is an Amsterdam-based ESG and supply-chain compliance platform built for EU mid-market compliance teams. Founded in 2022 (previously operating as Greencast.io), the company organizes its platform into three module families: carbon management, ESG compliance (CSRD, EU Taxonomy, VSME), and supply chain integrity (EUDR, PPWR, EUTR, EcoVadis). Its CBAM capability, as marketed on the dedicated product page archived in December 2025, was importer-side: upload import data to flag CBAM-scope products and suppliers, send MRR-aligned per-installation emissions requests with automated follow-ups, calculate reportable emissions, and forecast certificate costs with audit traceability.

As of July 2026, Coolset's dedicated CBAM product page redirects to its homepage, and CBAM no longer appears in its product navigation or on its plans page. Whether the module was discontinued, folded into the supply-chain-integrity offering, or is being relaunched is unclear, so buyers should confirm current CBAM availability with the vendor directly before shortlisting. Coolset's free CBAM Academy content hub, cost calculator, and downloadable checklist remain live.

Pricing is quote-based per module with no public tiers as of July 2026; the vendor states that onboarding, support, and a 4-week accelerator program are included with no setup fees. Coolset self-reports 500+ customers, ISO 27001 and SOC 2 Type II certification, and a TÜV-certified GHG methodology. Best for mid-market teams that want supplier data collection for CBAM inside one platform covering CSRD and EUDR, provided the module's status checks out.

2. CBAMBOO: The Dedicated CBAM Specialist

CBAMBOO is a London-based platform that does nothing except carbon border compliance, describing itself as "the operating system for carbon border compliance". Founded in 2023 and ISO 27001 certified, the company lists a six-person team on its website, led by founder and CEO Gabriel Rozenberg, and pairs its software with advisory services.

For importers, the platform covers monthly shipment uploads with live liability tracking, supplier emissions data requests and validation, purchase-order-level cost forecasting, carbon price scenario modeling, and a default value explorer that quantifies the cost premium of defaults against verified supplier data, a comparison worth understanding through our CBAM default values guide. CBAMBOO Pro, launched July 2025, adds XML report generation compatible with the EU CBAM Registry and a certificate planning and purchasing tool. A separate supplier-side product handles EU-methodology embedded emissions calculation and verification-ready reports; third-party sources report the supplier side is free of charge. Distribution partnerships with AEB (customs software) and ASUENE (Asian carbon accounting) extend its reach into customs data flows and Asian supplier networks.

CBAMBOO publishes no pricing on its own site as of July 2026. Third-party reviewers report figures of €9,000 per year (Basic) and €19,000 per year (Pro) for importers up to 1,000 tonnes, with a reported €31,000 per year enterprise tier; treat these as unconfirmed and quote-based. The reported price points suit mid-market and enterprise importers better than small ones. Read the full CBAMBOO review or visit cbamboo.com.

3. CarbonChain: Enterprise Depth for Commodity Supply Chains

CarbonChain is an enterprise carbon accounting platform built for commodity supply chains, serving EU importers and declarants, commodity traders, manufacturers, and trade-finance banks from offices in London and New York. Founded in 2019 and part of the Y Combinator Summer 2020 cohort, the company raised a $10 million Series A in April 2023 co-led by Union Square Ventures and Voyager Ventures.

Its CBAM product covers the full declarant workflow: automated supplier outreach and data collection at scale, emissions calculation with benchmark comparisons and cost scenario modeling, customs declaration upload with real-time validation, EU-template-aligned reports, and vendor-described automated XML generation for submission into the EU CBAM Registry; treat the XML claim as unconfirmed and ask to see the export live in a demo. CarbonChain claims asset-level data on 11,000+ commodity suppliers and 500+ completed CBAM declarations (both self-reported), backed by an SGS-validated GHG Protocol methodology and ISO 27001 certification. CarbonChain's CBAM case studies and marketing emphasize aluminium, steel, iron, and fertilizers; importers of cement, electricity, or hydrogen should probe coverage of those sectors in a demo.

Pricing is quote-based with no public pricing page as of July 2026. Free entry points include a free trial for declarants, a BETA CBAM cost estimator, and a public supplier catalogue with indicative (explicitly non-definitive) risk ratings for steel and aluminium installations. Best for large import books in steel and aluminium, where its supplier database delivers the most value. Read the full CarbonChain review or visit carbonchain.com.

4. kolum: Guided EU CBAM Workflows From Berlin

kolum (kolum GmbH) is a Berlin-based trade compliance platform whose shipping product today is EU CBAM, with UK CBAM and EUDR marketed as coming soon. Co-founder Helge Wieggrefe is a doctoral candidate at the University of Münster who has researched CBAM's legal implications since 2021, an unusually deep regulatory pedigree for a software founder; he runs the company with co-founder Marius Sprenger.

The EU CBAM module runs the obligation end to end: invite suppliers and request installation-level emissions data through guided workflows in more than 20 languages, calculate embedded emissions using EU default values or actual supplier data, prepare the annual CBAM declaration with audit-ready exports for the EU registry, and manage certificates with scenario-based cost forecasting. A supplier-comparison angle lets buyers weigh sourcing options by embedded emissions to reduce future certificate cost. Named customers are German industrial importers, including DENIOS SE, Böllhoff, and Keller & Kalmbach, and kolum partners with the customs broker Ziegler GmbH. Its free on-page CBAM cost calculator and CBAM Weekly newsletter give the product a strong content footprint.

Pricing is quote-based: the site lists no tiers and shows only "Custom" pricing with a demo CTA as of July 2026. Best for German-speaking and EU mid-market industrial importers that want guided, multilingual supplier workflows rather than an enterprise data platform. Read the full kolum review or visit kolum.earth.

5. Greenly: CBAM Inside a Carbon Accounting Platform

Greenly approaches CBAM from the carbon accounting side: the platform is known primarily for company carbon footprint measurement, and it positions CBAM as one obligation handled within a broader sustainability workspace rather than as a standalone product. That architecture suits companies whose CBAM exposure is real but secondary, where the same team owns the corporate footprint, CSRD preparation, and import compliance.

The suite-versus-specialist trade-off matters more here than any single feature. A suite platform consolidates emissions data, supplier engagement, and reporting across obligations, which reduces tool sprawl. A CBAM specialist goes deeper on declaration mechanics, registry-ready exports, and certificate planning. Importers evaluating Greenly should test four things in a demo: import-file ingestion against their actual customs data, supplier data collection aligned with CBAM methodology, default values updated to Implementing Regulation (EU) 2025/2621, and certificate cost forecasting for the 2027 purchase window.

We could not verify any published CBAM-specific pricing for Greenly as of July 2026; treat it as quote-based and confirm scope in writing before contracting. Best for carbon-accounting-first teams that prefer one sustainability platform over a dedicated CBAM tool. Read the full Greenly review for our complete assessment of its CBAM fit.

6. Dubrink: The Newer Entrant to Evaluate by Demo

Dubrink is the least publicly documented tool in this comparison. It positions itself as CBAM-focused software, but available public information on features, company background, and pricing is thin relative to the five vendors above, so our assessment relies on direct evaluation rather than published documentation. Pricing is not published as of July 2026.

Thin public documentation is not disqualifying: the CBAM software market is young, and newer entrants can be aggressive on price and responsive on product. It does shift the burden of verification onto the buyer. The six questions below form a minimum demo checklist for Dubrink or any lightly documented CBAM tool.

1. Confirm coverage of your sectors across iron and steel, cement, aluminium, fertilizers, electricity, and hydrogen
2. Test CN code mapping against your customs data, cross-checked with our CN codes tool
3. Verify default values match Implementing Regulation (EU) 2025/2621, not transitional-period datasets
4. Inspect the declaration export format and its compatibility with the EU CBAM Registry
5. Review the audit trail: source data traceability is what a verifier and a customs authority will ask for
6. Ask where data is hosted and which security certifications apply

Read the full Dubrink review for everything we could verify about the company and product.

Other CBAM Tools Worth Knowing

Beyond the six deep-reviewed platforms, four adjacent tool categories can cover part of the CBAM workload, sometimes at no extra cost. The options worth checking before you buy standalone software are listed below.

• Customs software with CBAM data flows. AEB, the German customs software provider, lists CBAMBOO as a partner: AEB Import Filing customers can enrich their EU import data and build CBAM reports on the CBAMBOO platform. If your customs filings already run through a major provider, ask what CBAM data it can export before adding a new tool.
• Regional carbon accounting partners. ASUENE, an Asia-focused carbon accounting platform, partners with CBAMBOO to support Asian manufacturers supplying EU customers. Relevant when your supplier base sits in Asia and needs local-language calculation support.
• Free vendor calculators. Coolset, CarbonChain (BETA estimator), and kolum all publish free CBAM cost calculators. These are scoping tools for estimating exposure, not filing tools, and none replaces a compliant declaration workflow.
• ERP and customs broker add-ons. Customs brokers and ERP vendors increasingly bundle CBAM data preparation into existing services. The functionality is usually narrower than dedicated software, but for a single-supplier import profile it can be sufficient.

Sector coverage gaps make this category genuinely useful. An importer of cement, for example, faces thinner support among the specialist platforms than a steel importer does, and may find a customs-broker workflow the more practical route in 2026.

CBAM Software vs Consultant vs DIY

CBAM software pays off when you import covered goods from three or more suppliers, plan to use actual emissions data instead of defaults, or need repeatable certificate cost forecasting; a consultant fits one-off setup tasks; DIY works for small, simple import profiles built on default values. The right choice follows from import volume, supplier count, and data strategy, not from vendor marketing.

The economics of 2026 shape this decision in a specific way. The CBAM factor is 2.5% in 2026, rising yearly to 100% by 2034, so net certificate cost is still small: a tonne of blast-furnace steel embedding roughly 2.0 tCO₂e carries about €150.56 in gross certificate value at the Q2 2026 price of €75.28 per tonne CO₂e, but only around €3.76 net after the free-allocation adjustment. The data obligation, by contrast, applies at full strength now. The declaration due September 30, 2027 must stand on verifiable 2026 data, and the record-keeping framework described in our CBAM reporting guide applies regardless of how small the certificate bill is. Buying software in 2026 is a purchase of data infrastructure, not of certificate savings.

The three approaches compare as follows.

Three practical rules cover most cases.

• Size the problem before pricing solutions. Run your import volumes through the free CBAM calculator to estimate embedded emissions and certificate exposure, and track the official certificate price with the price tracker. An exposure below a few thousand euros per year rarely justifies a five-figure subscription.
• Check the de minimis exemption first. Importers below 50 tonnes of covered goods per year are exempt entirely, which removes roughly 90% of importers from the regime. Confirm your position against the threshold rules before evaluating any tool.
• Match the tool to your data strategy. Default values require no supplier engagement and suit DIY handling; actual emissions data cuts certificate cost from 2027 onward but demands the supplier collection workflows that software automates and the verification chain covered in our CBAM verification guide.

A hybrid pattern is common among mid-market importers: a consultant handles authorization and first-declaration structure, software runs ongoing supplier data collection, and internal staff own the customs data feed. The three options are complements, not exclusive choices.

Frequently Asked Questions About CBAM Software

How Much Does CBAM Software Cost?

We could not verify published CBAM pricing for any of the six compared vendors on their own websites as of July 2026; every tool is effectively quote-based. The only concrete figures in the market are third-party-reported: reviewers cite €9,000 per year (Basic) and €19,000 per year (Pro) for CBAMBOO importer subscriptions up to 1,000 tonnes, with a reported €31,000 enterprise tier. Free options exist at the scoping stage, including vendor cost calculators and CarbonChain's declarant free trial. Budget expectations should scale with supplier count and data strategy rather than import value.

Do Small Importers Under 50 Tonnes Need CBAM Software?

No. Importers below the de minimis threshold of 50 tonnes of covered goods per year are exempt from CBAM obligations entirely. The exemption removes roughly 90% of importers, about 182,000 businesses, while more than 99% of embedded emissions remain covered by the mechanism. The one task a near-threshold importer cannot skip is monitoring cumulative annual mass across all covered goods, because crossing 50 tonnes mid-year triggers the full obligation. A spreadsheet and quarterly customs data review handle that monitoring without paid software.

Can CBAM Software File My Declaration Directly in the EU CBAM Registry?

Not in the sense of removing the declarant from the process. The documented state of the art is registry-compatible XML generation: CBAMBOO and CarbonChain both describe producing XML files for submission into the EU CBAM Registry, and kolum describes audit-ready registry exports. The authorized declarant remains legally responsible for the declaration filed through the registry and for the certificate surrender behind it, a lifecycle explained in our CBAM certificates guide. Treat any vendor claim of fully automated filing with skepticism and ask to see the submission workflow live.

Does CBAM Software Replace an Accredited Verifier?

No. Actual emissions data used in the annual declaration must be verified by an accredited verifier; declarations that rely solely on Commission-published default values are treated differently under the amended regime. Verifier registration in the CBAM Registry opens on September 1, 2026 under Regulation (EU) 2025/2083. Software prepares verification-ready datasets, maintains the audit trail, and manages supplier evidence, which reduces verification effort and cost, but the verifier's role is a separate legal requirement that no platform can absorb.

Is a Spreadsheet Enough for CBAM Compliance in 2026?

A spreadsheet can be enough for a narrow profile: one or two suppliers, one sector, and a default-values-only data strategy. Default values published under Implementing Regulation (EU) 2025/2621 remove the supplier data collection problem, which is the hardest part of the workload that software automates. The approach degrades quickly as suppliers multiply, because per-installation data requests, follow-ups, precursor tracking, and source-data traceability are exactly where manual processes break before the September 30, 2027 deadline.

Which CBAM Software Fits Steel and Aluminium Importers Best?

CarbonChain and CBAMBOO have the strongest documented fit for metals. CarbonChain's CBAM case studies and marketing emphasize aluminium, steel, iron, and fertilizers, and the company claims asset-level data on 11,000+ commodity suppliers; CBAMBOO's case studies and default-value tooling also center on heavy industry. Steel and aluminium carry high emission factors (roughly 2.0 tCO₂e per tonne for blast-furnace steel and 1.5 tCO₂e per tonne for primary aluminium, direct emissions), so actual supplier data delivers the largest certificate savings in these sectors as the CBAM factor rises after 2026. Importers in other sectors, and general importers with mixed baskets, should weight multilingual supplier workflows and sector breadth more heavily.
