Every European carbon accounting software tool reviewed
Berlin, Germany (also Paris, France)
Founded 2017
Quoted on request, not published
Demo on request
Best for: Companies that need an external body to vouch for the method and a reduction plan, not only an inventory
Plan A takes first place because it is the only platform here whose methodology has been examined by an independent certifier. TÜV Rheinland certification, a GHG Protocol-compliant approach, B Corp status and a stated SOC 2 position give an auditor or a procurement team several outside reference points. The product side leans on what happens after measurement: AI-assisted decarbonisation modelling, target-setting and supplier engagement tools meant to produce a reduction plan.
Plan A GmbH was founded in 2017 by Lubomila Jordanova and Nathan Bonnisseau, is headquartered in Berlin and keeps a second office in Paris.
The company has raised roughly $40M, including a $27M round in 2023, and its own site lists BMW, Visa, KFC, Sorare, Alphabet and Mollie as clients, which are vendor statements. Pricing is quoted only after a demo, there is no free tier, and the two-office setup means you should ask in which country your data is processed.
What Plan A does well
- TÜV Rheinland certified methodology, independent validation most competitors lack
- GHG Protocol compliant, B Corp certified and SOC 2 compliance stated
- Decarbonisation modelling and target-setting beyond measurement
- Established client base including BMW and Visa, per the vendor
Where Plan A falls short
- No published pricing; quote-only through a demo
- No free tier
- Two offices (Berlin and Paris) make data-processing questions less clear-cut
- Smaller scale and office footprint than Position Green
Standout feature. Plan A pairs a TÜV Rheinland certified calculation method with decarbonisation modelling, so the reduction plan inherits the same third-party validation as the inventory.

Best for: Teams without an in-house carbon specialist who want a named adviser attached to the software
Normative is the veteran of this list and the one that treats human guidance as part of the product. Every account comes with a named Climate Strategy Advisor who is certified in the GHG Protocol and works directly with your data and methodology, which suits a finance team handling its first inventory. Behind that sits a database that Normative describes as 349,000 verified emission factors.
The company was founded in Stockholm in 2014 by Kristian Rönn, Adam Wamai Egesa and Robin Undall-Behrend and also operates from Copenhagen and London.
Normative states that it has consulted with the European Commission on emissions accounting standards and contributed to a UN initiative on the topic. The costs of the advisor model are a bundled price you cannot see, no free tier or self-serve trial, and fewer named compliance modules than broader platforms, with no dedicated CBAM or EUDR module mentioned.
What Normative does well
- Founded 2014, one of the oldest dedicated carbon accounting vendors in Europe
- Named GHG Protocol-certified advisor included on every account
- Large emission factor database of 349,000 verified factors
- Track record of policy involvement with the European Commission and a UN initiative
Where Normative falls short
- No published pricing anywhere on the public site
- No free tier or self-serve trial
- Advisor-bundled model is less pure self-serve and may cost more
- Fewer named compliance modules than broader platforms
Standout feature. Normative includes a named, certified climate advisor on every account as standard, something no other tool on this list promises by default.
Berlin, Germany
Founded 2021
Free Starter plan (non-commercial); Data Pro €3,000/year; PCF Pro from €4,900/year; Enterprise on request
Free Starter plan for non-commercial use
Best for: Consultants, product teams and software vendors that need documented factors and PCF calculations, with a price they can read
Climatiq works from the data layer upwards, which makes it the odd one out among the ten. Studio products serve sustainability teams, with PCF Studio for product footprints and Data Studio for the emission factor collections, while an API lets developers embed calculations in their own software. The company counts over one million emission factors and names integrations with Celonis, Salesforce, Oracle, IFS and IntegrityNext.
Climatiq Technologies GmbH was founded in 2021 and is registered in Berlin at the Amtsgericht Charlottenburg under HRB 230334 B.
It is also the only vendor that shows money on the page: a free Starter plan for non-commercial use, Data Pro at €3,000 a year for a single user and PCF Pro from €4,900 a year, with API access reserved for the custom Enterprise plan. Premium datasets cost extra, the hosting location is not stated, and the pages we read describe no CSRD report builder, so a full inventory needs another tool or your own process.
What Climatiq does well
- Prices published for three of four plans
- Free Starter plan to test the data
- API and Excel integrations
- German company with a register entry
- PCF audit documentation in PCF Pro
Where Climatiq falls short
- Not a full reporting suite
- API only on Enterprise
- Premium datasets cost extra
- Data hosting region not stated
Standout feature. Climatiq is the only tool on this list that publishes euro prices, which lets a buyer budget a product footprint project before talking to sales.
Paris, France
Founded 2019
Quoted on request; three named tiers, no numeric prices published
Demo on request
Best for: Small and mid-sized companies that want a scoped first conversation and life cycle analysis in the same package
Greenly is built for the company that finds an enterprise suite oversized. Its pricing page names three tiers: GHG Report Compliance for Scope 1 and 2 accounting with financial-method Scope 3, Climate Action Ready, which it calls the most popular, with a physical Scope 3 analysis, and Net Zero Contributor with scenario simulation, a trajectory builder and a dedicated project manager. No amounts are printed, but you know what you are choosing between before the call.
The company was founded in Paris in 2019 and supports TCFD, SBTi, CBAM and EUDR, with life cycle analysis alongside Scope 1 to 3. The cautions are practical. Every tier still ends in a contact form, the API, SSO and extra entities or activity modules are separate add-ons that lift the effective cost, and no certification is stated on the pricing page. Greenly also has less independent analyst recognition than Sweep.
What Greenly does well
- Three named, feature-differentiated tiers instead of one "contact sales" button
- Life cycle analysis included alongside Scope 1 to 3 accounting
- Built for SMB and mid-market with less enterprise overhead
- Covers TCFD, SBTi, CBAM and EUDR frameworks
Where Greenly falls short
- No numeric prices; tiers are named but not priced
- No certifications stated on the pricing page
- Add-ons priced separately can grow the effective cost
- Less independent analyst recognition than Sweep
Standout feature. Greenly spells out what each of its three tiers contains, so a small company can scope the purchase without first booking a demo.

Founded 2020

Best for: Finance-led teams that want to treat carbon as a budget line, with forecasts and abatement costs
Cozero describes its product as carbon controlling, and the language is deliberate: forecasts with carbon price scenarios, targets, and a ranking of reduction actions by return on investment, payback period and marginal abatement cost. Data comes in by bulk upload, API or direct supplier input, and the calculation engine uses more than one million vetted emission factors with room for custom ones. Auditors get read-only access and an immutable audit trail.
Cozero GmbH was founded in 2020 and is registered at the Amtsgericht Berlin-Charlottenburg under HRB 218586 B. Be careful with the CSRD claim, because the vendor's page scopes it to ESRS E1 climate data. Hosting is described as an AWS environment with no region named, no Cozero-specific certification is stated (only the attestations of its cloud providers are listed), and there is no published pricing, only a demo request.
What Cozero does well
- Carbon controlling approach with forecasting, carbon price scenarios and ROI-ranked actions
- Over one million vetted emission factors and custom factor support
- Supplier engagement for Scope 3 and PCF solutions
- Audit management with read-only access and an immutable audit trail
Where Cozero falls short
- CSRD coverage is scoped to ESRS E1 climate data on the vendor’s own page
- Hosted on AWS with no region named on the security page
- No published pricing; demo request only
- No Cozero-specific certification stated; only its cloud providers’ attestations are listed
Standout feature. Cozero puts emissions into financial terms, with carbon price scenarios and ROI-ranked reduction actions in the same system that produces the disclosure data.
Munich, Germany
Pricing on request via demo

Best for: Mid-sized and large German-speaking companies that want software and consultants from one provider
ClimatePartner sells a hybrid: the ClimatePartner Hub for carbon accounting, supplier engagement and reduction, with consultants who help structure complicated datasets. For a team without a carbon specialist that is a real advantage, because part of the work is done for you. The cost is that the result partly depends on services, not only on software, and the same vendor also sells certified climate projects and carbon credits for remaining emissions.
The imprint names ClimatePartner GmbH at St.-Martin-Strasse 59 in Munich, registered at the Amtsgericht München under HRB 181521. The company says more than 6,000 companies work with it, which is a vendor figure.
The platform covers corporate footprints across Scopes 1 to 3, product footprints from raw material to end of life, supplier requests for primary data, and reports aligned with CSRD, SBTi and the GHG Protocol. The founding year is not stated on the pages we read, prices come only through a demo, and the hosting region is unnamed.
What ClimatePartner does well
- Software and consultants combined
- Corporate and product footprints
- Supplier data requests
- German company with a register entry
- Reports for CSRD and SBTi
Where ClimatePartner falls short
- Prices on request
- Part of the value is consulting
- Also sells climate projects
- Hosting region not stated
Standout feature. ClimatePartner is the only vendor here that puts consultants inside the software offer and also sells certified climate projects for the emissions left over.
Madrid, Spain
Founded 2019
No price list published; "Start for free" sign-up and a demo request are offered on the website
Demo on request
Best for: Spanish and Southern European product companies that report under EINF and CSRD and want a self-serve way in
Dcycle is the Madrid entry and the only one on the list that names Spain's EINF non-financial statement and the MITECO emission factors explicitly. The platform is aimed at businesses that make, transform and move physical goods, and it folds supplier, facility, purchasing and workforce data into one model. Frameworks listed include CSRD, GHG Protocol, GRI, CDP, EcoVadis, SBTi, PPWR, EUDR, VSME and the ISO 14001 family.
The operating company is The Wake Up Movement, S.L., entered in the Madrid Mercantile Registry in October 2019.
Modules cover product LCA, a CDP questionnaire, supplier engagement, multi-entity consolidation, integrations with SAP, Sage and Dynamics, and an assistant called Leia plus an MCP server for natural-language queries. A Start for free sign-up exists, but its limits are unstated, there is no price list, the trust center could not be read so certifications are unverified, and figures such as 70 percent less reporting time are the vendor's own.
What Dcycle does well
- Spanish regulatory coverage including EINF and MITECO emission factors
- Broad framework list from CSRD and CDP to ISO 14001 and EUDR
- Self-serve "Start for free" sign-up alongside demo requests
- Supplier engagement, product LCA and multi-entity consolidation in one platform
Where Dcycle falls short
- No published price list and free-tier limits are not stated
- Certifications could not be verified on the pages we read
- Efficiency figures such as 70 percent less reporting time are vendor claims
- Industrial and product-company focus is less suited to a services firm
Standout feature. Dcycle combines Spain's EINF and MITECO regulatory depth with CSRD, CDP and product LCA, and lets you open an account without a sales call.
Paris, France (also London, UK)
Founded 2020
Not published; quoted after a demo call
Demo on request
Best for: Large organisations that want analyst-rated carbon and ESG management and accept a quote-only process
Sweep is the platform on this list that leads with independent recognition: Leader in the 2026 IDC MarketScape for Carbon Management and in the 2026 Verdantix Green Quadrant for enterprise carbon management. It is B Corp certified and registered as an Entreprise à Mission, a French status that writes social and environmental commitments into the bylaws. Measurement, reporting and reduction planning sit in one product, with data collection automation for complex group structures.
Sweep was founded in 2020 by Rachel Delacour, Yannick Chaze and Raphael Güller and is headquartered in Paris, with a London office. It belongs to the Carbon Pricing Leadership Coalition, France Invest and IETA. Two points for a procurement file: no price is published and every quote follows a demo call, and the company opened a Denver office in 2025 as part of a US expansion, though it remains headquartered and incorporated in France.
What Sweep does well
- Named a Leader in both the 2026 IDC MarketScape and the 2026 Verdantix Green Quadrant
- B Corp certified and a legally registered Entreprise à Mission, not only a marketing claim
- Measurement, reporting and reduction planning in one platform
- Member of the Carbon Pricing Leadership Coalition, France Invest and IETA
Where Sweep falls short
- No published pricing; every quote needs a demo call
- No free tier or self-serve trial
- US office in Denver opened in 2025 as part of a US expansion
Standout feature. Sweep is one of few European carbon vendors named a Leader by both IDC and Verdantix in the same year.

Best for: Manufacturers and importers with SAP or Oracle that need Scope 3 and CBAM data from transactions
Carbmee builds the footprint from transaction records instead of surveys. It connects to ERP systems such as SAP and Oracle, reads procurement data and recalculates product carbon footprints dynamically as inputs change, tracing a number from the bill of materials to the board report. Separate solution pages cover CSRD, CBAM, EUDR, PPWR and Catena-X PCF, plus carbon cost forecasting and a digital battery passport.
Carbmee GmbH sits at Rosenthaler Strasse 36 in Berlin and is registered at the Amtsgericht Charlottenburg under HRB 225879 B.
The company says it was founded in early 2021 and works from Berlin and Munich, targeting enterprise manufacturers in automotive, consumer goods and electronics. It states 98 percent emission factor matching accuracy and go-live within one to three days, both its own claims. Prices are not published, the hosting region is not named, and a small services company will find most of the modules irrelevant.
What Carbmee does well
- ERP-connected transaction data
- Product carbon footprint module
- CBAM and EUDR coverage
- German company with a register entry
- Supplier engagement included
Where Carbmee falls short
- Aimed at large manufacturers
- No published prices
- Hosting region not stated
- Performance figures are vendor claims
Standout feature. Carbmee derives Scope 3 and product footprints from ERP transaction data, with CBAM and EUDR modules sold as separate solutions.

Best for: Food and beverage brands that need ingredient-level product footprints and primary supplier data
Altruistiq specialises in one sector. It describes itself as an enterprise sustainability platform for food and beverage, with corporate footprints, product footprints at ingredient level and supply chain decarbonisation based on primary supplier data. Listed use cases include franchise emissions in Category 14, on-pack sustainability claims and sustainable procurement, and the case studies come from brands such as Huel and Meadow Foods.
The contracting party is Expanding Circle Ltd, trading as Altruistiq, company number 13115702 in England and Wales, with its registered address at One London Wall.
That makes it a UK company outside the EU, which is a point for any buyer who requires an EU entity. The site states 220,000 or more curated emission factors updated quarterly and SOC 2 and ISO 27001 certification, both vendor statements. Prices come only via a demo, the founding year and hosting region are not stated, and outside food and beverage the fit weakens.
What Altruistiq does well
- Ingredient-level product footprints
- Supplier primary data
- Sector-specific use cases
- SOC 2 and ISO 27001 stated
- Advisory services available
Where Altruistiq falls short
- Food and beverage focus
- UK, not EU
- No published prices
- Hosting region not stated
Standout feature. Altruistiq is the only tool here built around a single industry, with ingredient-level footprints and sector use cases such as franchise emissions and on-pack claims.
