Seven CBAM software platforms compete directly with kolum for EU importer business in 2026: CBAMBOO, CarbonChain, Dubrink, Coolset, Greenly, osapiens, and IntegrityNext. Importers who need published pricing should compare Dubrink first, importers who want CBAM-only depth beyond kolum's supplier workflows should shortlist CBAMBOO, and importers with metals-heavy import books should evaluate CarbonChain before signing with kolum. kolum itself, reviewed in full in our kolum review, remains the strongest fit for German-speaking mid-market importers needing guided, multilingual supplier data collection. This page is for buyers whose profile points elsewhere.
The decision carries real deadlines regardless of which tool wins. The first annual CBAM declaration is due September 30, 2027, covering all 2026 imports. Certificate sales open February 1, 2027, and the official Q2 2026 certificate price is €75.28 per tonne CO₂e, published July 6, 2026. Whichever platform an importer picks needs to be collecting 2026 supplier data now.
kolum vs 7 CBAM Software Alternatives at a Glance
The table below compares kolum against seven alternatives on CBAM scope, published pricing, and the single strongest reason to pick each one instead.
| Tool | CBAM scope | Public pricing (July 2026) | Strongest reason to choose over kolum |
|---|---|---|---|
| kolum (reference) | EU CBAM only, end to end; UK CBAM, EUDR coming soon | None; "Custom" only | Baseline for this comparison |
| CBAMBOO | CBAM-only: shipment tracking, supplier data, default value explorer, XML | None; €9,000 to €19,000/yr reported by third parties | Deepest dedicated CBAM feature set, both sides |
| CarbonChain | Full declarant workflow, focused on steel, aluminium, iron, fertilizers | None; free trial for declarants | Commodity-grade data for metals-heavy books |
| Dubrink | CBAM-focused; PDF and XML declaration output | Published: €1,990 to €2,990/yr, free Connect tiers | Only vendor here with a public price list |
| Coolset | Multi-regulation suite; CBAM module status unclear | None; quote-based per module | One platform for CBAM plus CSRD, EUDR, GHG |
| Greenly | CBAM module inside carbon accounting suite, launched Feb 2025 | None; quote-based | Carbon-accounting-first teams, CBAM as one module |
| osapiens | HUB module: emissions calculation, certificate estimation, XML | None; tailored proposals | Enterprise teams on other osapiens HUBs |
| IntegrityNext | CBAM under a Scope 3 / Carbon Emissions category | None; supplier accounts free | Buyer-pays model, free supplier accounts |
Two patterns stand out: Dubrink alone publishes a public price, and scope splits into CBAM-only specialists (CBAMBOO, CarbonChain, Dubrink, kolum) versus CBAM-as-a-module suites (Coolset, Greenly, osapiens, IntegrityNext).
Why Importers Look Beyond kolum
Four gaps drive most searches for a kolum alternative, each documented in our kolum review.
- No published pricing. Only "Custom" appears on the pricing page, so budgeting starts with a demo. Buyers wanting comparable tiers look at Dubrink instead.
- EU CBAM is the only shipped module. UK CBAM and EUDR remain marketed as coming soon, not shipped, as of July 2026.
- No direct registry connection. kolum produces formatted export files for the EU CBAM Registry, not a documented API. The declarant still files it, a limit shared with most alternatives below.
- Early-stage company. kolum GmbH reportedly raised a €2.1 million pre-seed round in July 2024, per third-party funding trackers and unconfirmed by the company itself, less continuity signal than a longer-established vendor offers.
None of these four points disqualifies kolum for its core case. They explain why one buyer profile, not every buyer, looks elsewhere.
The 7 Best kolum Alternatives for CBAM Compliance
1. CBAMBOO: Deeper CBAM-Only Feature Set
CBAMBOO fits importers who want more CBAM depth than kolum's supplier-collection focus, including a default value explorer and purchase-order-level cost forecasting. The London-based, CBAM-only platform, founded in 2023, serves both EU importers and their non-EU suppliers, and CBAMBOO Pro adds XML report generation for the EU CBAM Registry. It publishes no pricing; third parties report €9,000 to €19,000 per year up to 1,000 tonnes, with a reported €31,000 enterprise tier, unconfirmed by the vendor. Full CBAMBOO review.
2. CarbonChain: Built for Metals and Commodity Importers
CarbonChain fits importers whose CBAM exposure sits mainly in steel, aluminium, iron, or fertilizers and who need supplier data at commodity scale. Founded in 2019 and reportedly backed by a $10 million Series A in April 2023, per third-party funding trackers and unconfirmed by the company itself, it claims asset-level data on 11,000+ commodity suppliers, well beyond kolum's guided-workflow model. Free entry points include a declarant free trial and a scenario-analysis free trial. Pricing is quote-based. Full CarbonChain review.
3. Dubrink: The Only Vendor With Published Pricing
Dubrink fits importers who want a fixed, public price before booking a demo, something no other vendor here offers. The Prague-registered company publishes full importer tiers: Connect free (conditional on suppliers holding paid licenses), Starter at €1,990 per year (up to 1,000 tonnes, 10 suppliers), and Premium at €2,990 per year (up to 15,000 tonnes, 50 suppliers), with custom Enterprise above that. Every paid tier covers one legal entity only. Full Dubrink review.
4. Coolset: A Broader EU Compliance Suite
Coolset fits importers who want CBAM inside a wider EU compliance platform covering CSRD, EUDR, and GHG accounting, provided its CBAM coverage is confirmed at demo. As of July 2026, Coolset's dedicated CBAM page redirects to its homepage, CBAM is absent from its pricing page's module list, and its own academy content called the module "coming soon" in an August 2025 article. Pricing is quote-based per module. Full Coolset review.
5. Greenly: CBAM Inside Full Carbon Accounting
Greenly fits teams that already run Scope 1 through 3 accounting and CSRD preparation and want CBAM on the same platform rather than as a separate tool. The Paris-based vendor added a dedicated CBAM module on February 13, 2025, inside a suite covering CSRD, EUDR, and life-cycle assessment. Its pricing page lists three named tiers with no prices attached, the same demo-first starting point as kolum. Full Greenly review.
6. osapiens: Enterprise HUB Module With XML Export
osapiens fits larger importers already running, or planning to run, other osapiens compliance HUBs who want CBAM as one more module in the same system. The "osapiens HUB for CBAM" covers declaration verification, direct and indirect emissions calculation, certificate quantity estimation against the EU ETS price, quarterly reports, a supplier Readiness Check, and XML export for EU submission. Pricing runs webinar-to-proposal, with no published rates and no stated free trial.
7. IntegrityNext: Free Supplier Accounts, Buyer-Pays Pricing
IntegrityNext fits importers whose main obstacle is getting non-EU suppliers to participate, since supplier accounts are free under its buyer-pays model. CBAM sits inside its Carbon Emissions category, framed around Scope 3 and supplier-engagement workflows rather than a standalone CBAM product. Pricing is set per offer and scaled by supplier count, with no published list; a free trial is reported by third-party review sites but unconfirmed by the vendor.
kolum vs Dubrink: Pricing Certainty vs Guided Multilingual Workflows
The sharpest contrast here sits between kolum and Dubrink, because each solves the other's biggest limitation. Dubrink publishes exact euro prices; kolum publishes none. kolum ships guided supplier workflows in 20+ languages with no disclosed tonnage cap; Dubrink's paid tiers cap out at 15,000 tonnes and 50 suppliers per entity before custom pricing applies. An importer near either Dubrink threshold, with one legal entity, gets the clearer price comparison; an importer with multiple entities or suppliers needing onboarding in a dozen languages leans back toward kolum, quote or no quote.
Which kolum Alternative Fits Your Import Profile
Match your situation to the shortlist below before booking any demo.
- Want a fixed price under €3,000/year and one entity. Start with Dubrink.
- Need the deepest CBAM-only feature set. Start with CBAMBOO.
- Import steel, aluminium, iron, or fertilizers at scale. Start with CarbonChain.
- Already run CSRD, EUDR, or GHG accounting on one platform. Start with Coolset or Greenly and confirm CBAM status at demo.
- Run other enterprise compliance HUBs already. Start with osapiens.
- Struggle to get suppliers to respond at all. Start with IntegrityNext or Dubrink's free supplier tier.
- Import under 50 tonnes of covered goods per year. Skip paid software; the de minimis exemption removes the obligation.
Before paying for any of the seven, size the problem with cbamguide.com's own free tools: the CBAM Cost Calculator and its downloadable report PDF estimate certificate exposure through 2034, and the CBAM Certificate Price Tracker, built on a live price API, tracks the official quarterly certificate price. Both run at no cost, the baseline every buyer should check first.

Frequently Asked Questions About kolum Alternatives
What Is the Best kolum Alternative for Published Pricing?
Dubrink is the only vendor compared here with a public price list as of July 2026: Starter at €1,990 per year (up to 1,000 tonnes, 10 suppliers), Premium at €2,990 per year (up to 15,000 tonnes, 50 suppliers), plus free Connect tiers on both sides. kolum, CBAMBOO, CarbonChain, Coolset, Greenly, osapiens, and IntegrityNext all remain quote-based.
Is There a Free Alternative to kolum?
No platform reviewed here is fully free for a paying-volume importer. Free entry points exist: Dubrink's Connect tier for suppliers, CarbonChain's declarant and scenario-analysis trials, and IntegrityNext's free supplier accounts. Importers below the 50-tonne de minimis threshold need no paid software, and cbamguide.com's own calculator and price tracker are free.
Which kolum Alternative Fits Steel and Aluminium Importers Best?
CarbonChain and CBAMBOO have the strongest documented fit for metals. CarbonChain's CBAM product concentrates on steel, aluminium, iron, and fertilizers with claimed data on 11,000+ commodity suppliers, and CBAMBOO's default value explorer also centers on heavy industry. Both go deeper on metals than kolum's general-importer workflow.
Does Any kolum Alternative Connect Directly to the EU CBAM Registry?
Not in the sense of removing the declarant from the process. kolum, Dubrink, and CBAMBOO describe formatted export files rather than a documented API into the CBAM Registry. CarbonChain's site describes automated XML generation, a claim worth confirming in a demo. The authorized declarant stays legally responsible for filing the CBAM declaration itself.
Should I Switch From kolum If I Only Need EU CBAM Compliance?
Not automatically. kolum's shipped product already covers EU CBAM end to end. Switch when a specific gap matters more, such as published pricing (Dubrink), commodity-grade metals data (CarbonChain), or a multi-regulation suite already covering CSRD or EUDR (Coolset, Greenly).
