CBAMBOO is a London-based, CBAM-only compliance platform founded in 2023 that serves both sides of the carbon border: EU importers above the 50-tonne annual threshold and the non-EU suppliers who must deliver embedded emissions data to them. Mid-market and enterprise importers of iron and steel, aluminium, cement, fertilizers, or hydrogen who need to collect actual emissions data from multiple non-EU suppliers should shortlist CBAMBOO. Importers close to the 50-tonne de minimis threshold, and companies that want CBAM handled inside a broader ESG or carbon accounting suite, should evaluate alternatives first. CBAMBOO publishes no pricing on its own website, and third-party sources report annual fees starting at €9,000, a level that makes commercial sense only once import volumes and supplier counts are material.
This review maps CBAMBOO's features to the definitive-phase obligations in force since January 1, 2026, examines its reported pricing, compares it against three alternatives in this cluster (Coolset, CarbonChain, and Greenly), and lists its limitations. Every vendor claim was checked against CBAMBOO's own pages in July 2026. Facts that could be sourced only from third parties are flagged as reported.
What CBAMBOO Does for CBAM Compliance
CBAMBOO covers four core definitive-phase workstreams: import liability tracking, supplier emissions data collection, annual declaration preparation, and certificate cost planning. The company describes itself as "the operating system for carbon border compliance" and builds exclusively for carbon border regulation (EU CBAM, plus UK CBAM insight content), not for general ESG reporting. The table below maps each CBAM obligation to the corresponding CBAMBOO feature.
| CBAM obligation | Rule or deadline | CBAMBOO feature |
|---|---|---|
| Track embedded emissions of 2026 imports | First annual declaration due September 30, 2027 | Monthly shipment data upload with live liability tracking |
| Collect actual emissions data from suppliers | Actual values avoid default-value mark-ups | Supplier data requests, validation, and a supplier-side platform |
| Prepare the annual CBAM declaration | Filed through the CBAM Registry | XML report generation compatible with the EU CBAM registry |
| Plan certificate purchases | Sales open February 1, 2027; 50% quarterly holding rule | Certificate planning and purchasing tool, price scenario modeling |
| Decide between default and actual values | Default values set by IR (EU) 2025/2621 | Default value explorer comparing default vs verified data cost |
Importer Features
For EU importers, CBAMBOO provides five documented functions: monthly shipment data upload with live CBAM liability tracking, supplier emissions data requests and validation (replacing spreadsheet and email workflows), purchase-order-level cost forecasting, a default value explorer, and carbon price scenario modeling. The default value explorer quantifies the premium an importer pays for relying on default values instead of verified supplier data. One in-product example on the vendor's importer page shows a default-value CBAM cost of €473.64 per tonne for silicon-electrical steel imported from India. The economics of that choice are explained in our CBAM default values guide.
The scenario modeling tool works from carbon price forecasts. CBAMBOO's published 2026 scenario range runs from €73/tCO₂e in Q1 to €91/tCO₂e in Q4. The official certificate prices published by the European Commission so far sit inside that band: €75.36/tCO₂e for Q1 2026 and €75.28/tCO₂e for Q2 2026, the current latest price. The CBAM price tracker publishes each official quarterly price as the Commission releases it.
CBAMBOO Pro
CBAMBOO Pro, announced July 8, 2025, is the upper product tier. It adds four capabilities on top of the base importer platform:
- Purchase-order-level CBAM exposure tracking, so finance teams see liability before goods ship
- Supply chain emissions data collection across multiple suppliers and installations
- XML report generation compatible with the EU CBAM registry for submission
- A certificate planning and purchasing tool aimed at the February 1, 2027 opening of certificate sales
One phrasing point matters here. CBAMBOO generates registry-compatible XML files; there is no evidence of a direct API connection into the registry itself. Authorized declarants still file through their own account, as described in our CBAM registry guide, and the certificate mechanics they must plan around (the 50% quarterly holding requirement, the September 30 surrender deadline, buyback, and cancellation) are covered in the CBAM certificates article.
Supplier Features
Non-EU suppliers get a parallel product: embedded emissions calculation following the EU methodology with sector-specific guidance, upstream data integration, creation of verification-ready CBAM reports, and secure sharing of verified statements with EU customers. The supplier side is reportedly free of charge, according to third-party review sites; CBAMBOO itself publishes no price list confirming this. A two-sided design matters because actual emissions data only reduces an importer's obligation if it can survive an accredited verifier's checks, a process detailed in our CBAM verification guide. Producers weighing whether to invest in supplying verified data will find the strategic context in our guide for exporters.
CBAMBOO Pricing (as of July 2026)
CBAMBOO publishes no pricing on its own website, so buying starts with a demo and a custom quote. The vendor's /pricing URL returns a 404 error, no pricing page appears in the site's sitemap, and no archived pricing page exists in the Wayback Machine. Every figure in the table below comes from third-party review sites, not from CBAMBOO, and should be treated as indicative only (as of July 2026).
| Plan (as reported) | Reported annual price | Reported scope |
|---|---|---|
| Basic | €9,000 | Importers, up to 1,000 tonnes |
| Pro | €19,000 | Importers, up to 1,000 tonnes |
| Enterprise | €31,000 | Larger importers, bespoke |
| Supplier access | Free of charge | Non-EU suppliers |
According to carboncomplete.com, importer plans are "free to start" before converting to a paid subscription, and search-indexed content attributed to netzerocompare.com reports the same €9,000 Basic and €19,000 Pro figures. None of these numbers appear on any CBAMBOO-owned page.
The reported fees exceed most importers' 2026 certificate exposure. An importer bringing in 1,000 tonnes of blast-furnace steel (roughly 2,000 tCO₂e embedded, per the emission factors in our steel sector guide) faces a gross certificate value of about €150,560 at the Q2 2026 price of €75.28/tCO₂e. Because the 2026 CBAM factor is 2.5%, the net certificate cost is roughly €3,764. A reported €9,000 to €19,000 software fee is therefore two to five times that importer's 2026 net certificate bill. The business case in 2026 rests on data collection, penalty avoidance, and preparing for the CBAM factor's rise toward 100% by 2034, not on immediate certificate savings.
CBAMBOO vs Coolset, CarbonChain, and Greenly
CBAMBOO's differentiator against every alternative in this cluster is pure CBAM specialization on both the importer and supplier side. The three platforms below approach CBAM from broader product scopes. Full scoring across all six reviewed vendors is in our best CBAM software roundup.
| Platform | Product scope | Typical fit | Full review |
|---|---|---|---|
| CBAMBOO | CBAM-only, importer and supplier sides, UK CBAM content | Mid-market and enterprise heavy-industry importers | This page |
| Coolset | Broader EU sustainability compliance platform with CBAM functionality | Mid-market EU companies consolidating compliance tools | Coolset review |
| CarbonChain | Supply chain carbon accounting with CBAM reporting | Commodity traders and metals supply chains | CarbonChain review |
| Greenly | General carbon accounting with CBAM support | SMEs starting broader carbon measurement | Greenly review |
Two questions decide the choice. First, is CBAM your only carbon compliance obligation? A company that also faces CSRD reporting or voluntary footprinting may prefer one broader platform over a specialist plus additional tools. Second, do you need supplier-side data collection at scale? CBAMBOO's free supplier product and validation workflow target exactly the multi-supplier data problem that spreadsheets handle poorly.
Company Background and Partnerships
CBAMBOO Ltd was founded in 2023 by Gabriel Rozenberg, who remains CEO. The company is registered in England and Wales (company number 14863105) with its registered office in London, holds EU trademark No. 019056316, and is ISO 27001 certified for information security. The team page lists roughly six people: the founder, a sales manager, a policy and research lead, two engineers, and a customer success lead. The company reportedly closed a pre-seed round of about £1 million in December 2023, led by Pale Blue Dot, according to funding aggregators including Nordic9 and Tracxn; the primary announcement is no longer accessible.
Two distribution partnerships extend the platform's reach:
- AEB SE (customs software): AEB lists CBAMBOO as its partner for CBAM report preparation. AEB Import Filing customers can enrich their EU import data and build CBAM reports on the CBAMBOO platform, a genuine data-flow integration.
- ASUENE (Asian carbon accounting platform): announced around November 2025, this partnership combines CBAMBOO's EU CBAM regulatory expertise with ASUENE's Asian manufacturer base through co-hosted webinars and referrals. It is a co-marketing alliance, not a product integration.
CBAMBOO also runs an active publishing operation: a blog with benchmark-value analysis and UK CBAM coverage, case studies (Stainless Steel Services and Mustad), webinars on topics such as price-risk hedging and verification-ready monitoring plans, and the roughly monthly CBAMBOO Insights newsletter, which has published 17 or more numbered editions since January 2025. Advisory services are offered alongside the software.
Limitations of CBAMBOO
Six limitations stand out from our evaluation, with the absence of public pricing being the most consequential for buyers:
- No public pricing. The vendor's pricing page returns a 404 and no price appears anywhere on cbamboo.com, which forces buyers into a demo before they can budget-compare.
- Reported cost pressure for smaller importers. The third-party review at carboncomplete.com states the platform "can be very costly for smaller businesses". Importers near the 50-tonne threshold should first confirm their status against the CBAM de minimis exemption before paying for any software.
- Heavy-industry skew. The same third-party review notes a focus mainly on iron, steel, and cement. Buyers in fertilizers, hydrogen, or electricity should probe sector depth during the demo.
- Small team. With roughly six listed staff, CBAMBOO is leaner than the enterprise vendors it competes with, and the company reportedly operates on about £1 million of pre-seed funding raised in December 2023.
- XML output, not direct registry integration. The platform generates registry-compatible XML for the annual declaration; declarants still handle submission themselves. The full filing workflow is described in our CBAM declaration guide.
- CBAM-only scope. Companies with CSRD or corporate footprint obligations need a second tool. CBAMBOO also offers no standalone public calculator; for a quick liability estimate without a demo, use our free CBAM calculator.
How We Evaluate CBAM Software
cbamguide.com is an independent editorial site with no affiliate relationships, referral fees, or paid placements from any vendor covered in this cluster. Vendor links on this page are plain homepage links. We verified each claim in this review against CBAMBOO's own pages, its sitemap, and archived snapshots in July 2026; claims that appear only on third-party sites are explicitly labeled as reported. We do not publish invented review scores, star ratings, user quotes, or customer counts. Our four evaluation criteria are: coverage of the definitive-phase obligations (declaration preparation, certificate management, supplier data collection), pricing transparency, regulatory currency against Regulation (EU) 2023/956 as amended by Regulation (EU) 2025/2083, and vendor stability. The full methodology applies identically across every review in the best CBAM software roundup, and the regulatory deadlines we test against are set out in the CBAM timeline.
CBAMBOO Review: Frequently Asked Questions
How much does CBAMBOO cost?
CBAMBOO does not publish pricing; quotes follow a demo. Third-party review sites report €9,000 per year for the Basic plan and €19,000 per year for Pro (each covering up to 1,000 tonnes), with €31,000 per year reported for enterprise customers, as of July 2026. These figures come from carboncomplete.com and netzerocompare.com, not from CBAMBOO, and should be confirmed directly with the vendor.
Is CBAMBOO free for suppliers?
Reportedly yes. Third-party sources state the supplier side is free of charge, and the product design (importers pay, suppliers contribute emissions data at no cost) supports that model. CBAMBOO publishes no price list confirming it, so suppliers should verify before committing data.
Does CBAMBOO submit declarations directly to the EU CBAM registry?
No direct submission is documented. CBAMBOO Pro generates XML reports compatible with the EU CBAM registry, and the authorized declarant then files the annual declaration through its own registry account. The first declaration, covering calendar-year 2026 imports, is due September 30, 2027.
Does CBAMBOO cover UK CBAM?
CBAMBOO positions itself as a carbon border compliance specialist covering UK CBAM alongside EU CBAM, and it publishes UK CBAM insight content on its blog and in its newsletter. Importers exposed to both regimes should confirm the depth of UK-specific product functionality during a demo.
Who should choose CBAMBOO over a broader carbon platform?
Importers whose only carbon obligation is CBAM and who must collect actual emissions data from multiple non-EU suppliers gain the most from CBAMBOO's specialization. Companies that also face CSRD reporting, corporate footprinting, or voluntary disclosure work are usually better served by a broader platform such as those compared in our best CBAM software roundup.
