Best European ESG & Sustainability Reporting Software

Looking for a European alternative to Watershed, Persefoni or Workiva? European ESG and sustainability reporting platforms cover carbon accounting, CSRD and EU Taxonomy disclosure, and decarbonisation planning, built around EU reporting frameworks from day one.

How we rank these tools — 4-step process
  1. 1
    European ownership, verified

    The company is headquartered and incorporated in the EU, EEA or Switzerland, and processes customer data in Europe. A US parent company disqualifies a tool from this page regardless of where its servers are.

  2. 2
    Category fit and hands-on review

    What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.

  3. 3
    Compliance and pricing check

    GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.

  4. 4
    Position on this page

    Placement on this page can be paid, and that can affect the order tools appear in. It never buys a listing: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.

Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Paid placement can affect the order in which tools appear; it never affects whether a tool is listed. Editorial policy

Key takeaways

  • Sweep ranks #1 among the eleven European ESG and sustainability reporting tools in this directory: a Paris platform named a Leader in both the 2026 IDC MarketScape for Carbon Management and the 2026 Verdantix Green Quadrant, B Corp certified and a registered Entreprise à Mission.
  • None of the eleven publishes a numeric price. Every vendor sells by quote, by module or after a demo. The only self-serve entry points are Greenomy’s free trial account and Dcycle’s "Start for free" sign-up, and neither page states how far the free tier goes.
  • Eleven tools sit in six EU countries: France (Sweep, Greenly, Sami), Germany (Plan A, preeco, Cozero), Sweden (Position Green, Normative), the Netherlands (Coolset), Belgium (Greenomy) and Spain (Dcycle). Every contracting entity is inside the EU, and no tool in the list is owned by a US parent.
  • Ownership still deserves a read. Sami has been majority-owned since November 2025 by SGS SA of Geneva, a Swiss rather than EU group. Greenomy has belonged to Position Green Group since September 2025, and Position Green itself has been majority-owned by the Nordic private equity firm Norvestor since 2022.
  • The category splits in two. Normative, Greenly, Sami, Plan A, Sweep, Cozero and Dcycle start from carbon accounting and grow outward to disclosure. Position Green, Coolset, Greenomy and preeco start from regulatory frameworks, with CSRD, ESRS or EU Taxonomy as the organising idea.
  • Only preeco names where the data sits: ISO 27001 certified data centres in Germany, with private cloud and on-premises options. Cozero says it runs on AWS without naming a region, and most others say nothing at all about hosting on their public pages.

A European ESG and sustainability reporting platform is software for collecting environmental, social and governance data and turning it into disclosures: carbon accounting across Scope 1, 2 and 3, double materiality assessments, and reports structured to CSRD and the ESRS standards, EU Taxonomy alignment or voluntary frameworks such as GRI and CDP.

In this directory the vendor must be established in Europe, and the contracting entity, not just the data centre, has to sit in the EU, EEA, UK or Switzerland. That distinction matters because a sustainability platform holds supplier invoices, energy bills and headcount data that feed financial-grade disclosures subject to assurance.

Every European esg-reporting tool reviewed

#1 Sweep

Paris, France Founded 2020 Not published; every plan is quoted after a demo call None stated; demo booking only

Best for: Enterprises wanting analyst-validated carbon and ESG data in one platform

  • Operating company. Sweep
  • Jurisdiction. EU (France)
  • Independent checks. B Corp certified; registered Entreprise à Mission under French law; Leader in the 2026 IDC MarketScape for Carbon Management and the 2026 Verdantix Green Quadrant
  • Source code. Closed source
  • Replaces. Watershed, Persefoni, Workiva

Sweep is a Paris and London sustainability data platform founded in 2020 by Rachel Delacour, Yannick Chaze and Raphael Güller.

It was named a Leader in the 2026 IDC MarketScape for Carbon Management and in the 2026 Verdantix Green Quadrant for enterprise carbon management, two analyst rankings a buyer can check without relying on vendor copy.

The product covers Scope 1, 2 and 3 tracking, data collection automation across complex organisations and wider ESG performance management. The company is B Corp certified and registered as an Entreprise à Mission under French law, which writes social and environmental commitments into its bylaws.

It is also a member of the World Bank’s Carbon Pricing Leadership Coalition, France Invest and the International Emissions Trading Association, which signals a policy and sustainable-finance orientation rather than a pure software one. The costs of that profile are opacity and breadth.

Pricing is not published anywhere on the site, every plan is reached through a demo, and there is no free tier. Sweep also opened a Denver office in 2025 as part of a US expansion, which matters only if your procurement policy cares where a vendor is growing.

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. One of few EU-headquartered vendors named a Leader by both IDC and Verdantix in the same year, a third-party shortcut during shortlisting.

#2 Position Green

Malmö, Sweden Founded 2015 Not published; quoted on request after a sales conversation None stated

Best for: Companies wanting software bundled with ESG advisory across CSRD and Taxonomy

  • Operating company. Position Green AB
  • Jurisdiction. EU (Sweden)
  • Independent checks. Not stated beyond framework coverage (CSRD, ESRS, EU Taxonomy, CSDDD)
  • Source code. Closed source
  • Replaces. Workiva, Diligent ESG, Sphera

Position Green is a Malmö-founded ESG software and advisory business, established in 2015 by Daniel Gaff, Björn Johansson and Rickard Häll. It combines CSRD and ESRS reporting, EU Taxonomy and CSDDD compliance, Scope 1 to 3 carbon accounting and supplier sustainability management in one platform.

It states that it supports more than 1,000 customers in over 30 countries from 11 offices, which makes it one of the larger dedicated ESG vendors headquartered in the EU. Unlike most tools in this category, it is sold with consulting and advisory services built around the software.

That suits an organisation that wants hands-on help interpreting an ESRS materiality assessment rather than a tool it configures alone. It also means the product is less of a self-serve proposition and will likely cost more and move more slowly than a pure SaaS tool.

Ownership has two layers. Norvestor, a Nordic private equity firm, acquired a majority stake in April 2022, and in September 2025 Position Green Group acquired Greenomy, the Brussels Taxonomy specialist. Pricing is not published and there is no trial, so every plan starts with a sales conversation.

What Position Green does well

  • CSRD, ESRS, EU Taxonomy and CSDDD alongside Scope 1 to 3 carbon accounting in one platform
  • Advisory and consulting bundled with the software rather than sold separately
  • Scale: 1,000+ customers, 30+ countries and 11 offices
  • Group includes Greenomy for deeper Taxonomy tooling

Where Position Green falls short

  • No published pricing and no free tier
  • Advisory-led model can cost more and move slower than self-serve software
  • Majority-owned by private equity firm Norvestor since 2022

Standout feature. Broad framework coverage delivered with bundled advisory in one relationship, instead of several point tools stitched together.

#3 Normative

Stockholm, Sweden Founded 2014 Not published; contact sales None stated

Best for: Teams wanting a named climate advisor alongside carbon software

  • Operating company. Normative
  • Jurisdiction. EU (Sweden)
  • Independent checks. GHG Protocol-aligned methodology; every account includes a GHG Protocol-certified Climate Strategy Advisor
  • Source code. Closed source
  • Replaces. Watershed, Persefoni

Normative is a Stockholm carbon accounting platform founded in 2014 by Kristian Rönn, Adam Wamai Egesa and Robin Undall-Behrend, with further offices in Copenhagen and London. It predates the CSRD-driven wave of newer entrants by several years and says it draws on a database of 349,000 verified emission factors.

The company states that it has consulted with the European Commission on emissions accounting standards and contributed to a UN initiative on the topic. What sets it apart is the human layer: every account includes a named, GHG Protocol-certified Climate Strategy Advisor who works with the customer’s data and methodology.

That puts Normative closer to Position Green than to lighter self-serve tools, and it is the main reason to choose it over a purely automated product. The trade-offs are the usual ones for this category.

Pricing is not published, there is no free tier or trial, and the advisor model can add cost and time for a team that simply wants software. Its public pages also mention fewer named compliance modules, such as EUDR or CBAM, than a broad platform like Coolset.

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. A named, GHG Protocol-certified climate advisor on every account, a level of human expertise most competitors do not include as standard.

#4 Plan A

Berlin, Germany Founded 2017 Quoted on request through a demo; no price list published None stated

Best for: Organisations prioritising decarbonisation planning over reporting alone

  • Operating company. Plan A GmbH
  • Jurisdiction. EU (Germany)
  • Independent checks. TÜV Rheinland certified methodology; GHG Protocol compliant; B Corp certified; SOC 2 compliance stated by the vendor
  • Source code. Closed source
  • Replaces. Persefoni, Watershed

Plan A is a Berlin carbon accounting and decarbonisation platform founded in 2017 by Lubomila Jordanova and Nathan Bonnisseau, with a second office in Paris. Its methodology carries TÜV Rheinland certification and the company describes it as GHG Protocol compliant.

It is also B Corp certified and states SOC 2 compliance, a combination of independent validations that few competitors in this category list together. The platform emphasises decarbonisation first. Alongside Scope 1 to 3 measurement and sustainability disclosure reporting it includes AI-assisted decarbonisation modelling, target-setting and supplier engagement tools aimed at turning a footprint into a reduction plan rather than a static disclosure.

Plan A lists clients including BMW, Visa, KFC, Sorare, Alphabet and Mollie on its own site. Pricing is quote-only through a demo request and there is no free tier.

Plan A has raised roughly 40 million US dollars in total funding, including a 27 million dollar round in 2023, so it is venture-backed rather than founder-funded.

Its two-office footprint can also make questions about where data is processed less clear-cut than with a single-site vendor. It is a fair fit for a company that already has a baseline footprint and now needs a credible path to reduce it, and a weaker fit for one that only needs a first inventory.

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. TÜV Rheinland-certified methodology combined with AI-assisted decarbonisation modelling: third-party-validated reduction planning, not just measurement.

#5 Coolset

Amsterdam, Netherlands Founded 2022 Quoted per module after a request; no numeric prices published None stated

Best for: EU mid-market companies covering many regulations with one vendor

  • Operating company. Coolset B.V.
  • Jurisdiction. EU (Netherlands)
  • Independent checks. None stated by the vendor
  • Source code. Closed source
  • Replaces. Workiva, Diligent ESG

Coolset is an Amsterdam compliance platform, founded in 2022 and registered as Coolset B.V. at Egelantiersgracht 572. It sells nine named modules: CSRD, EU Taxonomy, GHG Scope 1 to 3 accounting, EUDR with a simplified edition for SMEs, EUTR, VSME, PPWR and EcoVadis assessment preparation. By named regulatory coverage it is the broadest single platform in this category, which suits a company that faces several overlapping EU regulations at once. Instead of one flat subscription, each module is quoted separately.

Coolset states that onboarding, a customer success manager, sustainability researchers and a four-week accelerator programme are included at no extra cost on every module, and that the base platform includes unlimited users, analytics, automations and an audit trail designed for auditor use.

It is the youngest vendor in the category and its own site does not publish certifications the way Plan A or Sami do. No numeric price is published for any module. For a buyer facing EUDR, PPWR and CSRD obligations in the same year, the single-vendor route removes a procurement round, but ask how deep each module goes before assuming parity.

What Coolset does well

  • Broadest named regulatory coverage in the category, from CSRD to PPWR
  • Unlimited users included on the base platform
  • Onboarding, customer success manager and accelerator included at no extra module cost
  • Per-module quoting lets a buyer pay only for frameworks that apply

Where Coolset falls short

  • No numeric pricing published for any module
  • Youngest vendor in the category, founded 2022
  • No certifications stated on the vendor’s own site
  • Breadth can mean less carbon accounting depth than a pure-play tool

Standout feature. Nine regulatory modules from CSRD to PPWR under one vendor relationship, with unlimited users and onboarding included.

#6 Greenly

Paris, France Founded 2019 Three named tiers (GHG Report Compliance, Climate Action Ready, Net Zero Contributor), all quoted on request; add-ons priced separately None stated

Best for: SMBs wanting a clearly staged entry point into carbon accounting

  • Operating company. Greenly
  • Jurisdiction. EU (France)
  • Independent checks. None stated on the pricing page
  • Source code. Closed source
  • Replaces. Persefoni, Watershed

Greenly is a Paris carbon accounting platform established in 2019 and built primarily for small and mid-sized businesses. It covers Scope 1, 2 and 3 emissions accounting, life cycle analysis, and compliance support for frameworks including TCFD, SBTi, CBAM and EUDR.

Compared with enterprise carbon suites it carries less platform overhead, which is the main reason an SMB would pick it. Its pricing page names three tiers rather than hiding the structure. GHG Report Compliance is the entry tier, Climate Action Ready adds a physical Scope 3 analysis and is described as the most popular, and Net Zero Contributor adds scenario simulation, a trajectory builder and a dedicated project manager.

None lists a number, but the named differences make a first conversation easier to scope. Optional add-ons such as a custom API integration, SSO and extra entity or activity modules are priced separately, so the effective cost can grow beyond the base tier.

The vendor states no certifications on its pricing page, and it has less independent analyst recognition than Sweep. A company with a mature carbon team and complex multi-entity consolidation needs may outgrow it, which is part of why Sweep and Position Green rank above it here.

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. Three clearly differentiated tiers and LCA included, a more transparent structure than a single demo button even without published prices.

#7 Sami

Paris, France Founded 2020 Quoted on request; positioned as enterprise-grade capability at SME and mid-cap pricing None stated

Best for: French companies wanting certified carbon accounting at scale

  • Operating company. Sami
  • Jurisdiction. EU (France); majority shareholder SGS SA (Switzerland) since November 2025
  • Independent checks. GHG Protocol certified; ISO 27001 certified; B Corp certified (3-star Positive Company rating)
  • Source code. Closed source
  • Replaces. Persefoni, Watershed

Sami is a Paris decarbonisation and ESG reporting platform established in March 2020, with French offices in Marseille, Bordeaux and Lyon and a London office. It combines a Carbon Hub for Scope 1 to 3 measurement and net-zero strategy, an ESG Hub for sustainability reporting, and consulting and training.

It cites a database of more than 300,000 emission factors and says it serves more than 2,000 clients, describing itself as France’s most widely used carbon accounting software. Certification depth is its strongest card: GHG Protocol certification, ISO 27001 certification and B Corp certification with a 3-star Positive Company rating.

For procurement teams that need a security attestation at company level, that is more than most of this category states publicly. The ownership caveat is the clearest in the list. In November 2025 SGS SA, a Geneva testing, inspection and certification group, acquired a majority stake.

Sami remains a French-registered company headquartered in Paris, but the shareholder is Swiss rather than EU. Pricing is quote-only, with no number published. For a French buyer the presence in Paris, Marseille, Bordeaux and Lyon and the certification set make it a natural shortlist entry, while a buyer with a strict EU-ownership policy should ask what SGS’s stake means for the roadmap.

What Sami does well

  • Large stated client base of 2,000+ across Europe
  • GHG Protocol, ISO 27001 and B Corp certified
  • Carbon accounting, ESG reporting and consulting in one relationship
  • Emission factor database of 300,000+

Where Sami falls short

  • Majority shareholder SGS SA is Swiss (non-EU) since November 2025
  • No published numeric pricing
  • No free tier stated
  • Recent acquisition makes the independent roadmap less certain

Standout feature. A rare combination of scale and certification depth: GHG Protocol, ISO 27001 and B Corp together with a 2,000-plus client base.

#8 Greenomy

Brussels, Belgium Founded 2020 Free trial account advertised; paid plans quoted on request Free trial account

Best for: Corporates and financial institutions needing EU Taxonomy alignment data

  • Operating company. Greenomy, part of Position Green Group since September 2025
  • Jurisdiction. EU (Belgium)
  • Independent checks. None stated by the vendor
  • Source code. Closed source
  • Replaces. Diligent ESG, Workiva

Greenomy is a Brussels ESG platform established in 2020 and built specifically around EU Taxonomy alignment reporting and CSRD compliance, rather than broad carbon accounting.

It targets corporates, credit institutions and asset managers that must produce granular Taxonomy-aligned disclosure data, and it has distribution alliances with PwC Belgium, Deloitte and Accenture to reach enterprise customers.

Its own site advertises a free trial account rather than routing every visitor straight to a sales call, which is rare in this category. The depth and limits of that free access are not detailed on the marketing page, so confirm directly whether it covers a full reporting cycle before relying on it.

In September 2025 Greenomy was acquired by Position Green Group of Malmö, the ESG vendor ranked second in this directory. It continues to operate and sell as a separate Brussels-built product, but its roadmap now depends on a parent.

The narrow focus means it has no dedicated Scope 1 to 3 carbon accounting depth. It is best read as a Taxonomy and disclosure specialist to pair with a carbon tool, and its place near the bottom of this ranking reflects scope rather than product quality.

What Greenomy does well

  • Free trial account advertised, a self-serve entry point
  • Narrow, deep focus on EU Taxonomy alignment and CSRD
  • Distribution alliances with PwC Belgium, Deloitte and Accenture
  • Backed by Position Green Group since September 2025

Where Greenomy falls short

  • No dedicated Scope 1 to 3 carbon accounting depth
  • No certifications stated on the vendor’s own site
  • Acquired in September 2025, so long-term independence is less certain
  • Free trial limits are not documented on the marketing page

Standout feature. A self-serve free trial account combined with a narrow, deep focus on EU Taxonomy alignment data.

#9 preeco

Ulm, Germany Founded 2018 Not published; offer on request through a consultation call None stated; a 30-minute online consultation is the entry point

Best for: German-speaking companies wanting ESRS reporting with named German hosting

  • Operating company. preeco GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. Germany; cloud and private cloud run in ISO 27001 certified data centres in Germany on 100 percent green electricity, with an on-premises option
  • Independent checks. Data centres ISO 27001 certified; BITMi quality seal
  • Source code. Closed source
  • Replaces. Workiva, Diligent ESG

preeco is a compliance software company founded in 2018 and based in Ulm, registered as preeco GmbH at Amtsgericht Ulm under HRB 737082.

Its sustainability product is positioned as a central solution for CSRD-conformant ESG reporting, and the vendor states that all ten ESRS topical standards, E1 to E5, S1 to S4 and G1, are available, including a double materiality assessment and ten disclosure report generators. The carbon layer covers Scope 1, 2 and 3 emissions with a supplier portal, all 15 Scope 3 categories, GRI 302 and 305 cross-mapping, EUDR and 24 languages.

The vendor says the platform is ready to operate in 48 hours, supports multi-tenant group structures and offers support in German and English.

Hosting is the standout: cloud and private cloud in ISO 27001 certified data centres in Germany, with an on-premises option. preeco is a privacy-and-compliance suite first, with data protection, information security and whistleblowing sitting beside sustainability. That breadth helps a team that wants one vendor for several compliance duties and works less well for a buyer who wants a specialist carbon scientist. Pricing is not published; an offer comes after a 30-minute online consultation.

What preeco does well

  • All ten ESRS topical standards stated as productive, with double materiality assessment
  • Hosting in ISO 27001 certified German data centres, with private cloud and on-premises options
  • Scope 1 to 3 with supplier portal, EUDR and 24 languages
  • Multi-tenant structure for groups with several subsidiaries
  • Support in German and English

Where preeco falls short

  • No published pricing; offer on request after a consultation
  • Compliance suite first, less of a carbon specialist than Normative or Sweep
  • No analyst rankings or certifications for the product itself are stated, beyond its data centres

Standout feature. The only tool in this category that documents cloud, private cloud and on-premises hosting options, all with German data centres.

#10 Cozero

Berlin, Germany Founded 2020 Not published; demo request None stated

Best for: Finance and sustainability teams steering carbon like a financial KPI

  • Operating company. Cozero GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. AWS cloud environment; region not stated on the security page
  • Independent checks. None stated for Cozero itself; the page lists the independent attestations held by its cloud providers (ISO/IEC 27001, SOC 2 and others)
  • Source code. Closed source
  • Replaces. Watershed, Persefoni

Cozero is a Berlin climate software company founded in 2020, registered as Cozero GmbH at Amtsgericht Berlin-Charlottenburg under HRB 218586 B.

It pitches a shift from carbon accounting to carbon controlling: data collection by bulk upload, API or direct supplier input, a calculation engine with more than one million vetted emission factors, and dashboards designed so finance and sustainability teams work from the same data. Beyond the accounting layer, Cozero offers target setting, forecast building with carbon price scenarios and an evaluation of reduction actions by ROI, payback period and marginal abatement cost.

Reporting covers CSRD, CDP and internal governance with audit management and read-only access for auditors. Separate solution pages cover corporate and product carbon footprints, supplier engagement and CBAM.

Be precise about the CSRD claim: the vendor’s own CSRD page scopes it to ESRS E1 climate data, not the full set of ESRS standards. Hosting is stated as an AWS cloud environment without a named region. Pricing is not published and goes through a demo request. It sits well for an enterprise with an emissions focus, less so for a full sustainability statement.

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. Carbon treated as a financial variable: forecasts, carbon prices and ROI-ranked reduction actions inside the same platform that produces the disclosure data.

#11 Dcycle

Madrid, Spain Founded 2019 No price list published; "Start for free" sign-up and a demo request are offered on the website Self-serve "Start for free" sign-up; limits not stated on the page

Best for: Spanish and Southern European industrial companies needing EINF and CSRD

  • Operating company. The Wake Up Movement, S.L. (trading as Dcycle)
  • Jurisdiction. EU (Spain)
  • Independent checks. Not verified; the vendor points to a separate trust center that could not be read
  • Source code. Closed source
  • Replaces. Watershed, Persefoni, Workiva

Dcycle is a Madrid ESG data platform operated by The Wake Up Movement, S.L., registered in the Madrid Mercantile Registry in October 2019. It is aimed at companies that make, transform and move physical products and brings supplier, facility, purchasing and workforce data into one model.

The vendor lists frameworks including CSRD, GHG Protocol, EINF, GRI, CDP, EcoVadis, LCA, GLEC, SBTi, PPWR, EUDR, VSME and the ISO 14001 family. Its CSRD page promises every ESRS data point automated, from double materiality through to XBRL-tagged reports. Other modules cover Scope 1 to 3 carbon footprint, product LCA, a CDP questionnaire, supplier engagement, multi-entity management and integrations with SAP, Sage and Dynamics.

An AI assistant called Leia and an MCP server let teams query the data in natural language. It is the only Spanish vendor in this list and the only one that calls out the EINF non-financial statement and MITECO emission factors by name.

It offers a "Start for free" sign-up, but the limits are not stated, pricing is otherwise not published, and certifications could not be verified because its trust center is not readable without scripts. Claims 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. Local Spanish regulatory depth, EINF and MITECO factors, inside a platform that also covers CSRD, CDP and product LCA.

Carbon accounting or CSRD reporting: which one are you actually buying?

The two products overlap but are not the same job. Carbon accounting measures emissions from activity data such as electricity, fuel, travel and purchases, and applies emission factors under the GHG Protocol. CSRD reporting is wider: ESRS E1 covers climate, but the standard also asks for pollution, water, biodiversity, workforce, value chain and governance disclosures, plus a double materiality assessment that decides which of those apply to you.

Carbon-first tools such as Normative, Greenly, Sami and Cozero are strongest at the measurement layer. Cozero’s CSRD page, for instance, is explicit that its scope is ESRS E1 climate data. Framework-first tools such as Coolset, Position Green, Greenomy and preeco start from the disclosure requirement. preeco states that all ten ESRS topical standards, E1 to E5, S1 to S4 and G1, are productive in its product.

The practical test is the report you have to file. If your obligation is a climate transition plan and a Scope 3 inventory, a carbon-first platform is enough. If an auditor will test a full sustainability statement, check which ESRS standards the vendor covers in the product today rather than on a roadmap slide.

What does "European" mean when the vendor has investors, offices abroad or a new parent?

It means the contracting entity, and the decision rights behind it, sit in the EU, EEA, UK or Switzerland. Every tool here passes that test on paper, but three caveats are worth knowing before you sign.

Sami remains a Paris company, yet since November 2025 its majority shareholder is SGS SA of Geneva, which is Swiss and therefore outside the EU. Greenomy is still built in Brussels but now sits under Position Green Group. Position Green itself is majority-owned by Norvestor.

Offices matter less than owners, but they are not irrelevant. Sweep opened a Denver office in 2025 and Position Green lists offices in North America, so check which entity processes support tickets and which sub-processors touch your data. Plan A works from Berlin and Paris, Normative from Stockholm, Copenhagen and London.

Most of these vendors do not state their shareholders on their public pages. If your procurement policy cares about independence rather than jurisdiction, ask each vendor to name its largest shareholder and describe its change-of-control terms in writing.

Why does no vendor publish a price, and how do you budget anyway?

Because pricing in this category depends on variables the vendor cannot see until you describe your company: number of legal entities, number of sites, which frameworks apply, how much supplier data you will collect and how much advisory support you want bundled. Coolset prices each of its nine modules separately. Greenly names three tiers and charges extra for a custom API, SSO and further entities. Position Green and Normative bundle consultants or climate advisors with the software.

To compare quotes, ask every vendor for the same six things: the price per legal entity, whether users are unlimited, which frameworks are included in the base price, what onboarding costs, how emission factor databases are licensed, and what the renewal uplift is. Coolset states that unlimited users, onboarding and a customer success manager are included on its base platform, which makes that comparison easier.

A free account is a way to test the workflow, not a way to file a report. Greenomy’s own page says its free trial account exists, and Dcycle offers a "Start for free" sign-up, but neither describes a free tier large enough to cover a full CSRD cycle.

What should you ask about hosting and security?

Ask for the data centre and the operator, not the continent. Sustainability data feeds disclosures that are subject to limited assurance, so you need an audit trail that shows who changed which data point and when, and you need to know where that trail is stored.

The public pages in this category are thin on this. preeco names ISO 27001 certified data centres in Germany and offers private cloud and on-premises. Sami and Plan A state certifications at the company level, ISO 27001 for Sami and a TÜV Rheinland-certified methodology plus a stated SOC 2 compliance for Plan A. Cozero says it runs on AWS and that its cloud providers hold independent attestations, but it does not name a region on the page we read.

Treat anything the vendor did not publish as an open question for the security questionnaire, and request the sub-processor list as a standard part of the data processing agreement.

How we selected and ranked these 11 tools

Every tool on this page is in the European Purpose directory, which means the operating company is established in Europe and we have verified that from the company register or the vendor's own legal notice rather than from a marketing page. Tools headquartered outside Europe are not eligible, however good they are.

  1. Feature verification (weight: 40%). We check each capability against the vendor's own documentation and product pages, and record what the tool does rather than what the category is assumed to include.
  2. Ease of adoption (weight: 30%). Integrations, published API access, trial availability and how much configuration stands between signing and a usable result.
  3. Value and transparency (weight: 30%). Published pricing counts in a vendor's favour; quote-only pricing is recorded as quote-only rather than estimated. We weigh what a buyer gets for the entry price, not the headline feature count.
  4. Editorial review. Every page is researched and drafted with AI assistance, and the compliance and pricing claims are checked against the vendor's documentation before it is published under the founder's editorial responsibility. The three weights above decide the order; a position is a ranking against the other European tools in this category, not an absolute score.

Vendor-reported outcomes — ROI figures, margin uplift, time saved — are labelled as vendor claims wherever they appear on this page. We have not audited them, and neither has anyone else who quotes them. Read our full editorial process for how pages are re-verified.

Frequently asked questions

Sweep holds #1 in this directory: a Paris-headquartered platform for carbon and wider ESG data, named a Leader in the 2026 IDC MarketScape for Carbon Management and the 2026 Verdantix Green Quadrant, and B Corp certified. The right answer depends on the job.

Position Green when you want software bundled with advisory across CSRD, EU Taxonomy and CSDDD, Coolset for the broadest named module list, Normative for a named climate advisor on every account, Plan A for a TÜV Rheinland-certified methodology, and preeco when German hosting and an on-premises option matter.

Position Green covers CSRD, ESRS, EU Taxonomy and CSDDD reporting alongside Scope 1 to 3 carbon accounting.

Coolset bundles nine modules including CSRD, EU Taxonomy, VSME, EUDR and PPWR. preeco states that all ten ESRS topical standards are available in its product, with a double materiality assessment and ten disclosure report generators. Dcycle describes CSRD reporting from double materiality to XBRL-tagged reports. Cozero’s CSRD solution is limited to ESRS E1 climate data. Always confirm coverage against the standards in your own materiality outcome.

There is no permanently free reporting tool among these eleven. Greenomy advertises a free trial account, and Dcycle offers a "Start for free" sign-up on its website, but neither vendor documents the limits of that free access, and paid plans are quoted on request. Every other vendor sells through a demo or a quote. If budget is the constraint, ask whether a lighter framework such as VSME, which Coolset lists as a named module, is enough for your obligation.

None of the eleven publishes a numeric price. Greenly comes closest by naming three tiers with described contents, and Coolset states which services are included at no extra cost on every module, but both still route to a quote. Plan to request quotes from at least three vendors with an identical scope statement.

Sami has been majority-owned by SGS SA, a Swiss testing and certification group headquartered in Geneva, since November 2025. Position Green has been majority-owned by Norvestor, a Nordic private equity firm, since April 2022, and acquired Greenomy in September 2025. Greenomy therefore sits under Position Green Group. No tool in this list has a US parent, which is the disqualifying condition in this directory.

Greenly positions itself for small and mid-sized businesses and names three clearly differentiated tiers with life cycle analysis included. Coolset targets EU mid-market companies and includes unlimited users. Sami describes its positioning as enterprise-grade capability at SME and mid-cap pricing. For a German-speaking company, preeco offers a 48-hour start and support in German and English. All of them are quote-based, so scope the request tightly before asking.

Only preeco documents this: its sustainability product is offered as cloud, private cloud on a dedicated virtual server, or on-premises in your own data centre. The cloud and private cloud variants run in ISO 27001 certified data centres in Germany. None of the other ten vendors describes a self-hosted option on its public pages, and none is open source, so treat a self-hosting request as a negotiation point rather than a given.

Dcycle is the Madrid-based option and references the Spanish non-financial information statement (EINF) and MITECO emission factors alongside CSRD, GHG Protocol and CDP. The website is available in several languages including Spanish. The company is The Wake Up Movement, S.L., registered in the Madrid Mercantile Registry in October 2019, and it trades as Dcycle.

Best European ESG & Sustainability Reporting Software

Looking for a European alternative to Watershed, Persefoni or Workiva? European ESG and sustainability reporting platforms cover carbon accounting, CSRD and EU Taxonomy disclosure, and decarbonisation planning, built around EU reporting frameworks from day one.

How we rank these tools — 4-step process
  1. 1
    European ownership, verified

    The company is headquartered and incorporated in the EU, EEA or Switzerland, and processes customer data in Europe. A US parent company disqualifies a tool from this page regardless of where its servers are.

  2. 2
    Category fit and hands-on review

    What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.

  3. 3
    Compliance and pricing check

    GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.

  4. 4
    Position on this page

    Placement on this page can be paid, and that can affect the order tools appear in. It never buys a listing: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.

Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Paid placement can affect the order in which tools appear; it never affects whether a tool is listed. Editorial policy

Key takeaways

  • Sweep ranks #1 among European ESG platforms on independent analyst recognition (a Leader in the 2026 IDC MarketScape and Verdantix Green Quadrant) plus verified B Corp and Entreprise à Mission status.
  • None of the eleven vendors publish numeric pricing on their own sites — every one of them is sold through a demo or a sales conversation, which is normal for this category rather than a red flag specific to any one tool.
  • Coolset and Greenomy are the two built specifically around CSRD and EU Taxonomy disclosure; the other six cover both carbon accounting and reporting more evenly.
  • Two of the eight are no longer fully independent: Greenomy joined Position Green Group in September 2025, and Sami's majority stake was acquired by SGS SA, a Swiss (non-EU) company, in November 2025 — both stay EU-headquartered and EU-built, and we say so plainly in each review.
  • Normative, founded in 2014, is the longest-established dedicated carbon accounting vendor in this group, and the only one that bundles a named, GHG Protocol-certified climate advisor into every account.

Looking for a European alternative to Watershed, Persefoni or Workiva? European ESG and sustainability reporting platforms cover carbon accounting, CSRD and EU Taxonomy disclosure, and decarbonisation planning, built around EU reporting frameworks from day one.

Every European ESG & Sustainability Reporting tool reviewed

#1 Sweep

Paris, France Founded 2020 Quoted on request No published free tier

Best for: Companies wanting an analyst-recognised platform spanning measurement to reduction

  • Operating company. Sweep
  • Jurisdiction. EU (France)
  • Certifications. B Corp certified; registered Entreprise à Mission under French law
  • Source code. Closed source
  • Replaces. Watershed, Persefoni, Workiva

Sweep is a Paris and London-based sustainability data platform founded in 2020 by Rachel Delacour, Yannick Chaze and Raphael Güller, built to help companies measure, manage and act on carbon emissions and wider ESG data across their value chain. It was named a Leader in the 2026 IDC MarketScape for Carbon Management and a Leader in the 2026 Verdantix Green Quadrant for enterprise carbon management, two of the more closely watched independent analyst rankings in this category.

The company holds B Corp certification and is a legally registered Entreprise à Mission under French law, a status that writes social and environmental commitments into its corporate bylaws.

It is also a member of the World Bank's Carbon Pricing Leadership Coalition, France Invest and the International Emissions Trading Association. Sweep positions its platform around embedding sustainability into core operations rather than treating it as a compliance checkbox, covering Scope 1, 2 and 3 emissions tracking alongside broader ESG performance data.

Pricing is not published; every plan is quoted after a demo. Sweep opened a Denver, Colorado office in 2025 as part of a US expansion, which is worth knowing if vendor location matters to your procurement policy, though the company remains headquartered and incorporated in France.

#2 Position Green

Malmö, Sweden Founded 2015 Quoted on request No published free tier

Best for: Larger organisations wanting software bundled with advisory across many EU markets

  • Operating company. Position Green AB
  • Jurisdiction. EU (Sweden)
  • Certifications. Not stated by the vendor beyond framework coverage (CSRD, ESRS, EU Taxonomy, CSDDD)
  • Source code. Closed source
  • Replaces. Workiva, Diligent ESG, Sphera

Position Green is a Malmö-founded ESG software and advisory business, established in 2015, that combines CSRD and ESRS reporting, EU Taxonomy and CSDDD compliance, Scope 1-3 carbon accounting and supplier sustainability management inside a single platform. The company runs 11 offices across Europe and North America and states it supports more than 1,000 customers in over 30 countries, making it one of the larger dedicated ESG vendors headquartered in the EU.

Unlike most of the other tools in this category, Position Green is sold with consulting and advisory services built around the software rather than as a pure self-serve SaaS product, which suits an organisation that wants hands-on help interpreting ESRS materiality assessments rather than a tool it configures alone. A majority stake was acquired by Norvestor, a Nordic private equity firm, in April 2022; the company remains headquartered and operated from Sweden.

In September 2025, Position Green Group acquired Greenomy, the Brussels-based EU Taxonomy specialist also reviewed on this page (#8). The two remain separately built and sold products under one parent company, which is worth factoring in if you want vendor diversity across your compliance stack.

#3 Normative

Stockholm, Sweden Founded 2014 Quoted on request No published free tier

Best for: Teams that want a named climate expert working alongside the software

  • Operating company. Normative
  • Jurisdiction. EU (Sweden)
  • Certifications. Not stated on the vendor's about page beyond GHG Protocol-aligned methodology
  • Source code. Closed source
  • Replaces. Watershed, Persefoni

Normative is a Stockholm-founded carbon accounting platform, established in 2014 by Kristian Rönn, Adam Wamai Egesa and Robin Undall-Behrend, with additional offices in Copenhagen and London. It is one of the longest-established dedicated carbon accounting vendors in this category, predating the CSRD-driven wave of newer entrants by several years, and states it draws on a database of 349,000 verified emission factors.

A distinguishing feature is that every Normative account includes a named, GHG Protocol-certified Climate Strategy Advisor who works with the customer's data and methodology directly, rather than leaving interpretation entirely to self-service software. The company states it has consulted with the European Commission on emissions accounting standards and contributed to a UN initiative on the topic, and is backed by climate-focused investors.

Pricing is not published on Normative's public pages; the vendor directs prospective customers to a separate sales conversation. For a company that wants software plus a dedicated point of contact rather than a pure self-serve tool, Normative sits closer to Position Green in that respect than to the lighter self-serve tools further down this list.

#4 Plan A

Berlin, Germany Founded 2017 Quoted on request No published free tier

Best for: Organisations prioritising decarbonisation modelling over reporting alone

  • Operating company. Plan A GmbH
  • Jurisdiction. EU (Germany)
  • Certifications. GHG Protocol compliant, TÜV Rheinland certified methodology, B Corp certified, SOC 2 compliant
  • Source code. Closed source
  • Replaces. Persefoni, Watershed

Plan A is a Berlin-headquartered carbon accounting and decarbonisation platform founded in 2017 by Lubomila Jordanova and Nathan Bonnisseau, with a second office in Paris. Its methodology carries TÜV Rheinland certification and is described by the company as GHG Protocol compliant, and the business also holds B Corp certification and states SOC 2 compliance. Plan A has raised roughly $40M in total funding, including a $27M round in 2023.

The platform's stated emphasis is "decarbonisation-first": alongside Scope 1-3 measurement and sustainability-disclosure reporting, it includes AI-assisted decarbonisation modelling, target-setting and supplier engagement tools meant to turn a carbon footprint into a reduction plan rather than a static disclosure. The company lists clients including BMW, Visa, KFC, Sorare, Alphabet and Mollie on its own site.

Pricing is quote-only, reached through a demo request rather than a published price list. For a buyer whose primary goal is cutting emissions rather than just reporting them, Plan A's certified methodology and reduction tooling are the clearer differentiators against the more reporting-first tools in this category.

#5 Coolset

Amsterdam, Netherlands Founded 2022 Quoted per module No published free tier

Best for: EU mid-market companies needing CSRD, Taxonomy, EUDR and CBAM in one place

  • Operating company. Coolset B.V.
  • Jurisdiction. EU (Netherlands)
  • Certifications. Not stated by the vendor
  • Source code. Closed source
  • Replaces. Workiva, Diligent ESG

Coolset is an Amsterdam-based compliance platform, founded in 2022 and registered as Coolset B.V. at Egelantiersgracht 572, that targets EU mid-market companies with nine named modules: CSRD, EU Taxonomy, GHG Scope 1-3 accounting, EUDR (plus a simplified EUDR for SME edition), EUTR, VSME, PPWR and EcoVadis assessment preparation. It is the broadest single platform in this category by named regulatory-framework coverage.

Rather than one flat subscription, Coolset prices each module separately after a quote request, and states that onboarding, a customer success manager, sustainability researchers and a four-week accelerator programme are included at no extra cost on every module. The base platform includes unlimited users, analytics, automations and an auditor-facing audit trail rather than gating collaboration behind seat counts.

Founded in 2022, Coolset is the youngest company on this page, and its own site does not publish specific certifications the way Plan A or Sami do. For a buyer whose priority is covering the full stack of new EU regulatory frameworks (CSRD, Taxonomy, EUDR, CBAM-adjacent reporting) under one vendor relationship, the module breadth is the strongest reason to shortlist it.

#6 Greenly

Paris, France Founded 2019 Quoted on request, 3 named tiers No published free tier

Best for: SMBs and mid-market companies wanting a clearly staged entry point

  • Operating company. Greenly
  • Jurisdiction. EU (France)
  • Certifications. Not stated by the vendor on its pricing page
  • Source code. Closed source
  • Replaces. Persefoni, Watershed

Greenly is a Paris-founded carbon accounting platform, established in 2019, built primarily for small and mid-sized businesses that want a lighter-weight alternative to enterprise carbon accounting suites. The product covers Scope 1, 2 and 3 emissions accounting, life cycle analysis (LCA), and compliance support for frameworks including TCFD, SBTi, CBAM and EUDR.

Its pricing page names three tiers rather than hiding the structure entirely: GHG Report Compliance is the entry tier (Scope 1 and 2 physical accounting, Scope 3 financial accounting, grouped kick-off calls); Climate Action Ready, described as the most popular tier, adds a physical Scope 3 analysis and a dedicated kick-off call; and Net Zero Contributor adds scenario simulation, a trajectory builder and a dedicated project manager.

None of the three list a number — every tier still routes to a "get in touch" form — but the named, feature-differentiated structure is more transparent about what a buyer is actually choosing between than most competitors' single "book a demo" button.

Optional add-ons include a custom API integration, SSO, and extra entity or activity modules, priced separately. For an SMB comparing several EU carbon accounting vendors, Greenly's tier structure makes it easier to have a scoped first conversation than a vendor offering only one undifferentiated "contact sales" path.

#7 Sami

Paris, France Founded March 2020 Quoted on request No published free tier

Best for: French companies wanting France's largest carbon accounting client base

  • Operating company. Sami
  • Jurisdiction. EU (France); majority shareholder is SGS SA, headquartered in Geneva, Switzerland (non-EU), since November 2025
  • Certifications. GHG Protocol certified, ISO 27001 certified, B Corp certified (3-star Positive Company rating)
  • Source code. Closed source
  • Replaces. Persefoni, Watershed

Sami is a Paris-founded decarbonisation and ESG reporting platform established in March 2020, with additional French offices in Marseille, Bordeaux and Lyon and a London office.

The product combines a Carbon Hub for Scope 1-3 emissions measurement and net-zero strategy, an ESG Hub for sustainability reporting, and consulting and training services, drawing on a database the company describes as over 300,000 emission factors. Sami states it serves more than 2,000 clients across Europe and describes itself as France's most widely used carbon accounting software.

The company holds GHG Protocol certification, ISO 27001 certification and B Corp certification with a 3-star Positive Company rating. In November 2025, SGS SA — a Geneva, Switzerland-headquartered testing, inspection and certification group — acquired a majority stake in Sami.

Sami itself remains a French-registered, Paris-headquartered company, and the acquisition is framed by both parties as a "one-stop shop" pairing Sami's software with SGS's certification and audit services across its global network. Because SGS is Swiss rather than EU/EEA, this is the clearest ownership caveat among the eleven tools on this page; a buyer with a strict EU-ownership procurement requirement should confirm current terms directly.

Pricing is quote-only, with the company describing its positioning as "enterprise-grade capabilities at SME-mid-cap pricing" rather than publishing numbers.

#8 Greenomy

Brussels, Belgium Founded 2020 Free trial account; paid plans on request Free trial available

Best for: Financial institutions and corporates needing EU Taxonomy alignment data specifically

  • Operating company. Greenomy; part of Position Green Group since September 2025
  • Jurisdiction. EU (Belgium)
  • Certifications. Not stated by the vendor
  • Source code. Closed source
  • Replaces. Diligent ESG, Workiva

Greenomy is a Brussels-founded ESG SaaS platform, established in 2020, built specifically around EU Taxonomy alignment reporting and CSRD compliance rather than broad carbon accounting. It targets corporates, credit institutions and asset managers who need to produce granular Taxonomy-aligned disclosure data for sustainable-finance requirements, and has built distribution alliances with PwC Belgium, Deloitte and Accenture to reach enterprise customers.

Unlike the other seven tools in this category, Greenomy's own site advertises a free trial account rather than routing every visitor straight to a sales call, though the depth of that free tier and its suitability at company scale should be confirmed directly before assuming it covers a full CSRD reporting cycle.

In September 2025, Greenomy was acquired by Position Green Group (#2 on this page), the Malmö-headquartered ESG vendor; Greenomy continues to operate and sell as a distinct, Brussels-built product.

For a buyer whose primary need is EU Taxonomy alignment data specifically — rather than full Scope 1-3 carbon accounting or broad ESRS reporting — Greenomy's narrower focus can mean less unused platform surface than the broader suites higher on this page, at the cost of needing a separate tool if carbon accounting depth is also required.
