Five platforms stand out as CBAMBOO alternatives for EU importers and their non-EU suppliers in 2026: Dubrink, CarbonChain, kolum, Coolset, and Greenly. Dubrink suits buyers who want published pricing and a free supplier tier; CarbonChain fits large-volume steel, aluminium, iron, and fertilizer importers; kolum suits German-speaking mid-market importers needing multilingual supplier workflows; Coolset and Greenly fit companies that want CBAM handled inside a broader ESG or carbon accounting suite rather than a CBAM-only tool. CBAMBOO itself remains the deepest CBAM-only, two-sided platform on the market, reviewed in full on our CBAMBOO review.
This page compares all 5 alternatives against CBAMBOO on scope, pricing transparency, and best-fit buyer profile, using the method applied across the CBAM software review cluster. Dates below reflect the definitive phase in force since January 1, 2026 under Regulation (EU) 2023/956, as amended by Regulation (EU) 2025/2083.
Why Importers Look Beyond CBAMBOO
Three factors drive most searches for a CBAMBOO alternative: unpublished pricing, a heavy-industry skew, and a small vendor team. CBAMBOO publishes no price list; third-party reviewers report annual fees of €9,000 (Basic) and €19,000 (Pro) for importers up to 1,000 tonnes, with a reported €31,000 enterprise tier, figures unconfirmed by the vendor. Its case studies and default-value tooling also concentrate on iron, steel, and cement, so buyers in fertilizers, hydrogen, or electricity should probe sector depth in a demo, and its roughly six-person team is smaller than several alternatives below.
None of this makes CBAMBOO the wrong choice. These are simply the questions worth testing against alternatives, alongside two constants that apply regardless of vendor:
- The first annual CBAM declaration, covering calendar-year 2026 imports, is due September 30, 2027, and certificate sales open February 1, 2027.
- Importers below the 50-tonne annual de minimis threshold are exempt from CBAM entirely, which removes roughly 90% of importers (about 182,000 businesses) from the market for any CBAM software.
CBAMBOO Alternatives Compared (2026)
The table below compares CBAMBOO against its 5 leading alternatives on CBAM scope, supplier-side support, pricing transparency, and best-fit buyer, based on vendor documentation reviewed in July 2026.
| Tool | CBAM scope | Supplier-side product | Public pricing (as of July 2026) | Best for |
|---|---|---|---|---|
| CBAMBOO (baseline) | CBAM-only: shipment tracking, default value explorer, registry-compatible XML | Yes, reportedly free | None; €9,000-€31,000/yr reported by third parties | Mid-market and enterprise heavy-industry importers |
| Dubrink | CBAM-only: emissions calculation, PDF and XML declaration output, certificate forecasting | Yes, published Connect (free) and Premium (€1,990/yr) tiers | Yes, full price list from €1,990/yr | Single-entity importers up to 15,000 t/yr wanting price transparency |
| CarbonChain | Full declarant workflow for aluminium, steel, iron, fertilizers | No dedicated supplier product; public supplier catalogue with risk ratings | None; quote-based, free declarant trial | Large commodity import books in metals and fertilizers |
| kolum | End-to-end EU CBAM: supplier collection in 20+ languages, declaration exports | Supplier invitations within the importer workflow, not a separate paid product | None; site lists only "Custom" pricing | German-speaking and EU mid-market industrial importers |
| Coolset | Importer-side data collection and cost forecasting; CBAM module status unclear | No standalone supplier product documented | None; quote-based per module | Teams combining CBAM with CSRD, EUDR, and other EU rules |
| Greenly | CBAM handled within a broader carbon accounting suite | No standalone supplier product documented | None; three named tiers, no published prices | Carbon-accounting-first teams managing CBAM as one obligation |
Dubrink is the only vendor here, CBAMBOO included, with a full public price list, and its free supplier Connect tier is the only direct match for CBAMBOO's free-for-suppliers model. The other four alternatives concentrate their product on the importer side.
The 5 Best CBAMBOO Alternatives for 2026
1. Dubrink: The Only Alternative With Published Pricing
Dubrink is the clearest alternative for buyers frustrated by CBAMBOO's lack of a public price list. Importer tiers run Connect (free, requires suppliers with a paid license), Starter at €1,990 per year (up to 1,000 tonnes, up to 10 suppliers), Premium at €2,990 per year (up to 15,000 tonnes, up to 50 suppliers), and Enterprise at custom pricing. Supplier licenses mirror this: a free Connect tier and a €1,990 per year Premium tier for multi-entity suppliers.
Like CBAMBOO, Dubrink serves both sides of the CBAM relationship, and its declaration output is PDF and XML files rather than a documented direct connection to the CBAM Registry, the same limitation CBAMBOO carries. A Dubrink Starter license costs less than the net 2026 certificate obligation on roughly 530 tonnes of blast-furnace steel at the Q2 2026 price of €75.28 per tonne CO₂e, a comparison no buyer can run against CBAMBOO without first requesting a quote. Founded July 2024 in Czechia, Dubrink has a shorter track record than CBAMBOO. Read the full Dubrink review or visit dubrink.com.
2. CarbonChain: More Scale for Metals and Commodity Importers
CarbonChain outscales CBAMBOO on enterprise commodity depth. Founded in 2019 and backed by a $10 million Series A, the London-based platform serves EU importers, commodity traders, and trade-finance banks, with a CBAM product concentrated on aluminium, steel, iron, and fertilizers. It claims asset-level data on 11,000+ commodity suppliers (self-reported), a database CBAMBOO does not match in stated scale.
Pricing is quote-based, the same transparency gap CBAMBOO has. CarbonChain offers more free entry points, however: a free declarant trial, a free scenario-analysis trial, free supplier risk ratings through its Supplier Catalogue, and a free CBAM calculator. Importers exposed to cement, electricity, or hydrogen should note the marketing emphasizes the other four sectors. Read the full CarbonChain review or visit carbonchain.com.
3. kolum: Guided Multilingual Supplier Workflows
kolum's differentiator against CBAMBOO is language depth, not price transparency: the Berlin-based platform guides non-EU suppliers through emissions data requests in more than 20 languages, targeting the problem of collecting data from production managers who rarely work in English. Co-founder Helge Wieggrefe has researched CBAM's legal implications since 2021, an unusually deep regulatory pedigree for the company's size.
Pricing is quote-based, with the site listing only "Custom", so kolum offers no pricing advantage over CBAMBOO. Named customers include German industrial importers such as DENIOS SE and Böllhoff. kolum publishes no separate paid supplier product; suppliers participate through invitations inside the importer's own subscription, simpler than CBAMBOO's two-sided licensing but with less documented supplier tooling. Read the full kolum review or visit kolum.earth.
4. Coolset: One Platform for CBAM Plus Broader ESG Compliance
Coolset suits buyers who find CBAMBOO's CBAM-only focus too narrow. The Amsterdam-based platform organizes its product into carbon management, ESG compliance (CSRD, EU Taxonomy, VSME), and supply chain integrity (EUDR, PPWR, EUTR, EcoVadis) modules, so a company already tracking CSRD or EUDR can consolidate tooling instead of running CBAMBOO alongside a separate ESG platform.
As of July 2026, Coolset's dedicated CBAM product page redirects to its homepage and CBAM does not appear on its pricing page's module list, so buyers should confirm current availability before shortlisting it. Pricing is quote-based per module, matching CBAMBOO's own transparency gap. Read the full Coolset review or visit coolset.com.
5. Greenly: CBAM Inside a Full Carbon Accounting Suite
Greenly fits the same buyer profile as Coolset from a different angle: companies whose CBAM exposure is real but secondary to a wider carbon accounting and CSRD workload. The Paris-based vendor added a dedicated CBAM module on February 13, 2025, covering supplier data collection, embedded emissions calculation, and report file preparation, though it does not advertise CBAM Registry integration or certificate management, two areas where CBAMBOO goes deeper.
Greenly's pricing page lists three named tiers but publishes no prices; every tier routes to a "Get in touch" CTA, leaving pricing transparency roughly even with CBAMBOO. Best for teams already running, or planning to run, footprint and CSRD work on the same platform. Read the full Greenly review or visit greenly.earth.
How to Choose Among CBAMBOO Alternatives
The right alternative follows from three questions: how many suppliers you need to onboard, how much of your CBAM exposure sits in metals versus other sectors, and whether CBAM is your only compliance obligation.
- Need a published price list before you request a demo? Start with Dubrink.
- Managing a large steel, aluminium, iron, or fertilizer import book? Start with CarbonChain.
- Onboarding non-EU suppliers who do not work in English? Start with kolum.
- Already tracking CSRD, EUDR, or other EU sustainability rules? Start with Coolset or Greenly.
- Need the deepest CBAM-only feature set on both the importer and supplier side? CBAMBOO remains the benchmark; compare it directly in our best CBAM software roundup.
Whichever platform you shortlist, cbamguide.com's own free tools remain the no-cost baseline: the CBAM Cost Calculator projects certificate costs through 2034 and generates a downloadable cost report, and the CBAM Certificate Price Tracker, fed by our live ETS price API, publishes the official quarterly price the moment the Commission releases it. Both run with no registration and no demo call.
How We Evaluate CBAM Software
cbamguide.com is an independent editorial site. We have no commercial relationship with CBAMBOO or any of the five alternatives compared here (Dubrink, CarbonChain, kolum, Coolset, and Greenly), we accept no affiliate commissions or vendor payments, and every vendor is named in plain text with no tracking links. Facts were checked against each vendor's own site as of July 2026; unverified figures are marked as third-party-reported, and where no public or third-party pricing could be found, that gap is stated plainly rather than estimated. No vendor compared here reviewed or approved this article.
Frequently Asked Questions About CBAMBOO Alternatives
What is the closest alternative to CBAMBOO?
Dubrink is the closest structural match: both platforms serve importers and non-EU suppliers as separate, connected products, not passive data sources. The practical difference is pricing transparency. Dubrink publishes a full price list starting at €1,990 per year, while CBAMBOO's pricing is quote-based, with only third-party-reported figures of €9,000 to €31,000 per year available.
Is there a free alternative to CBAMBOO?
No alternative here is free for importers. The closest free entry points are Dubrink's importer Connect tier, which requires suppliers already holding a paid Dubrink license, and CarbonChain's free declarant trial and calculator. cbamguide.com's own CBAM Cost Calculator and Price Tracker are free with no registration for any importer size.
Which CBAMBOO alternative is best for steel and aluminium importers?
CarbonChain has the strongest documented fit, with a CBAM product concentrated on aluminium, steel, iron, and fertilizers and a claimed database of 11,000+ commodity suppliers. CBAMBOO's own case studies and default-value tooling also skew toward iron, steel, and cement, so importers should compare both platforms directly.
Do all CBAMBOO alternatives support non-EU suppliers?
Not equally. CBAMBOO and Dubrink offer dedicated, separately licensed supplier-side products. kolum and CarbonChain support supplier engagement inside the importer workflow (multilingual invitations, a public risk-rating catalogue) without a standalone paid product. Coolset and Greenly handle supplier requests inside their broader ESG platforms.
Do I need any CBAM software if I import under 50 tonnes a year?
No. Importers below the 50-tonne annual de minimis threshold are exempt entirely, removing roughly 90% of importers, about 182,000 businesses, from the regime. Near-threshold importers only need to monitor cumulative annual mass, a task a spreadsheet and the free CBAM Cost Calculator handle without paid software.
