10 Best ESG Reporting Software in 2026: Pricing and Trade-offs
The ten platforms below share a goal, a defensible sustainability disclosure, but arrive at it from different directions. Novisto, Sweep and Position Green were designed around disclosure standards such as CSRD, ESRS, ISSB and GRI. IBM Envizi, Persefoni, Sphera and Watershed began with energy, carbon or life cycle data and later built reporting on top. Enablon, Workiva and Diligent extend platforms first used for EHS operations, financial filings and board governance respectively. On price, Persefoni offers a free Pro tier, IBM Envizi explains how its bundles are sized without stating figures, and the remaining eight quote after a demo or scoping call.

ESG reporting software converts scattered sustainability information into a disclosure that regulators, investors and assurance providers can rely on. A typical platform pulls governance, workforce, energy and emissions records out of business systems and from individual staff, runs methods like the GHG Protocol, links every datapoint to frameworks including CSRD, ISSB, GRI and CDP, and stores the evidence and approvals that sit behind every number. The market divides by origin. Novisto, Sweep and Position Green were built for disclosure, with CSRD and multi-framework reporting at the centre. IBM Envizi, Persefoni, Sphera and Watershed grew from carbon, energy or life cycle data and now produce complete reports. Enablon, Workiva and Diligent extend EHS, financial reporting and board governance platforms into sustainability. Persefoni offers a free tier and IBM Envizi explains its bundle structure; the other eight vendors quote.

Tool profiles
Novisto
mid-marketNovisto, headquartered in Montreal, builds a sustainability management platform for companies whose disclosures go to several audiences at once. The vendor says its clients track more than 700 metrics on average and reports a 50 percent average gain in efficiency when submitting disclosures; both figures are Novisto's own.
The CSRD product follows the reporting cycle from start to finish. It begins with a double materiality assessment aligned to EFRAG guidance, with automatic scoring. A contributor portal then gathers ESRS datapoints from colleagues and sends reminders when inputs are late. Scope 1 to 3 emissions can be calculated inside the platform. Cross-referencing connects ESRS requirements to GRI and IFRS equivalents, so one datapoint can serve several disclosures. Role-based approvals and an audit trail record who changed and signed off each figure. For electronic filing, Novisto maps XBRL tags automatically, and it also supports SFDR and the EU Taxonomy.
Standards content is a particular strength. Novisto holds a SASB licence covering standards for 77 industries, offers a GRI-licensed solution, and partners officially with the IFRS Foundation on software for IFRS S1 and S2. That combination suits companies answering both European regulators and investors who rely on SASB and ISSB.
Reporting output extends beyond regulatory filings. A Microsoft add-on embeds metrics that update automatically into annual reports, and peer benchmarking helps teams set targets. Balchem and PagerDuty are quoted as customers, PagerDuty in connection with the S&P Global Corporate Sustainability Assessment.
No pricing is published. Novisto suits companies whose priority is multi-framework disclosure with strong controls; those mainly seeking deep carbon modelling may prefer a carbon-first platform.
Where it is strong
- Double materiality aligned to EFRAG, with automatic scoring
- Live metrics can be embedded in reports through a Microsoft add-on
- Cross-referencing links ESRS, GRI and IFRS requirements

IBM Envizi
enterpriseIBM Envizi is a suite for managing and reporting ESG data, with particular depth in energy and facilities. Its emissions engine applies the GHG Protocol to Scope 1 and 2, uses AI to accelerate Scope 3 calculations, and includes a financed emissions module for organisations with investment or lending portfolios. Supply Chain Intelligence collects supplier inputs for the first two Scope 3 categories, purchased goods and capital goods.
Data consolidation is where Envizi stands out. Utility bill analytics and interval meter analytics pull energy and water data from facilities into one place, which matters for organisations with hundreds of buildings or sites. Reporting modules handle framework disclosures, building ratings, benchmarks, internal surveys and programme management for sustainability initiatives. Planning Analytics models reduction targets next to financial plans, so emissions goals can be tested against budgets. Other software can reach the calculation engine through the Emissions API or an Excel add-in.
Envizi is one of the few vendors in this comparison to explain its pricing structure publicly. The suite is priced by data volume measured in Accounts, a count covering activity records, supplier records and location-level KPIs. Essentials stops at 1,000 Accounts, Standard spans 1,001 to 5,000, and Premium starts at 5,001 and runs to 15,000 or beyond. ESG reporting, Scope 3 and other modules sit on top, and a calculator gives an indicative figure, although a final price requires IBM sales.
According to IBM, GPT Group cut energy and water spending by USD 20 million annually. Envizi suits property-heavy and multi-site organisations; office-based companies with a handful of locations may find the energy tooling more than they need.
Where it is strong
- The public pricing structure explains how bundles are sized
- Financed emissions module serves lenders and investors
- Planning Analytics models reduction targets beside financial plans
Watch-outs
- A final figure still requires scoping with IBM sales
- Energy and property depth is more than office-only companies need

Sweep
mid-marketSweep is a platform for carbon and ESG data with a strong focus on the European reporting regime. Its CSRD module combines a preconfigured library of ESRS indicators with a double materiality assessment organised by sector, questionnaires for collecting data, gap analysis and a report generator assisted by AI.
Review is handled carefully. Approvers can accept or reject an entire survey or an individual answer, and comments and supporting documents stay attached to the response, which leaves an evidence trail for assurance providers.
The final stage assembles the material indicators in the format regulators require and applies machine-readable tags for the European Single Access Point, the EU's planned central repository for company disclosures. Sweep says its platform keeps pace with changing standards and shows, at each datapoint, how the simplified ESRS alter the requirement. That feature helps teams that began CSRD preparation under the original standards and now need to understand what has moved.
Data is entered once and reused. The same inputs map to CDP, GRI, ISSB and the EU Taxonomy, and support targets aligned with SBTi, so a company answering several frameworks does not repeat collection for each.
Sweep publishes case studies featuring SSE, Swisscom and MV Credit. Its free CSRD Materiality Builder produces a double materiality matrix and lets teams begin the assessment before committing to a platform.
No price is published. Sweep suits companies in CSRD scope, including financial institutions, energy companies and manufacturers, that want the full workflow from materiality to tagged filing in one tool.
Where it is strong
- One round of data entry serves GRI, CDP, the EU Taxonomy, ISSB and SBTi-aligned targets
- Each datapoint shows what the simplified ESRS change
- A free CSRD Materiality Builder exports a double materiality matrix
Watch-outs
- No public pricing

Enablon
enterpriseEnablon is the Wolters Kluwer software line for environment, health and safety, risk and ESG. Its ESG Excellence product gathers and validates ESG data from over 100 enterprise applications, normalises it into standard indicators, and calculates KPIs aligned to reporting frameworks that refresh automatically when the source data changes.
The reporting layer is a distinguishing choice. Disclosure runs on CCH Tagetik, a Wolters Kluwer product for corporate performance management that finance departments use. As a result, sustainability and finance staff can work within one process, combining narrative and numbers in reports that conform to CSRD, CDP, GRI, TCFD and IFRS. For companies where the CFO owns the sustainability statement, sharing tooling with financial close can simplify controls and sign-off.
Beyond disclosure, the platform runs materiality assessments, manages net zero programmes for Scope 1, 2 and 3 emissions down to asset level, and supports climate risk analysis. The vendor points to its position as a leader in Verdantix's 2025 Green Quadrant covering ESG and sustainability reporting software.
Enablon's operational heritage is its main advantage. Existing Enablon customers in health, safety or environmental compliance are able to reuse that operational data, such as incident, energy and waste records, for disclosure rather than collecting it again.
Pricing is not published; a consultation or demo is required. Enablon suits large enterprises with substantial EHS operations and a finance function that wants sustainability reporting under the same controls as financial reporting.
Where it is strong
- Supports CSRD, CDP, GRI, TCFD and IFRS reporting
- Scope 1 to 3 emissions tracked down to individual assets
- Materiality, net zero programmes and climate risk in one platform
Watch-outs
- No public pricing
- Delivers most value to buyers already using other Enablon or CCH Tagetik products

Persefoni
mid-marketPersefoni is a platform for carbon accounting and climate disclosure, and it is the only vendor in this comparison offering a free tier. Its pricing page describes two products aimed at different stages of maturity.
Persefoni Pro is free and self-service, needing no card and carrying no trial window or expiry. It is aimed at companies needing a full-scope emissions footprint for customer requests like CDP and EcoVadis questionnaires. Guided workflows walk users through the inventory, and a Sustainability Report Builder combines narrative answers with emissions data into a first report.
Persefoni Advanced is the enterprise product. On top of Pro it brings market-based accounting for renewable energy purchases, finer-grained and custom or proprietary factors, APIs linked through an integration hub, reduction modelling and seats without a cap. Persefoni describes the platform as SOC 2 compliant, which matters when emissions data feeds regulated disclosures.
Framework-specific outputs are sold separately as GHG Metrics Reports. Beyond a methodology report, the range covers ISSB, CSRD, CDP, UK SECR and California's climate disclosure laws. Concierge Support is another paid add-on. None of these add-ons, nor Advanced itself, carries a published price.
The structure makes Persefoni easy to start and harder to budget at scale. A company can build its inventory at no cost, but the moment it needs a framework-formatted report, it moves into quoted territory, so buyers should price the add-ons they will need early.
Persefoni suits companies whose first need is a credible carbon inventory and which may later expand into formal climate disclosure. Organisations needing broad social and governance reporting will find the coverage concentrated on carbon.
Where it is strong
- The free Pro tier includes full-scope emissions accounting plus a report builder
- Advanced adds custom factors, APIs and reduction modelling
- Vendor states the platform is SOC 2 compliant
Watch-outs
- Framework-formatted outputs cost extra
- Coverage of social and governance topics trails its carbon depth

Position Green
mid-marketPosition Green, a European ESG software vendor, says over 1,000 companies use it. The CSRD product covers the reporting cycle in sequence: a double materiality assessment, ESRS templates, data collection, and finally the Statement Studio, which consolidates all inputs into a sustainability statement that can be exported. The platform supports both the original and the revised ESRS, VSME for smaller companies, SFDR and the EU Taxonomy.
AutoReporting, documented in the help centre, uses AI to propose answers to ESRS or VSME datapoints, drawing on documents the company uploads. Each suggestion references the file it came from, and suggestions never overwrite data that has already been reported. A controller launches the run while colleagues review the drafts, which keeps human approval in place while reducing the time spent searching policies and reports for evidence. AI must be enabled on the account for the feature to work.
The platform also covers carbon accounting and supply chain assessments, and connects to Fortnox and Microsoft Dynamics 365, which helps companies whose financial and operational data sits in those systems.
Support for VSME is relevant to smaller companies and suppliers that are outside mandatory CSRD scope but receive sustainability data requests from larger customers.
No price is published, and a tailored demo with a specialist is the route to a quote. Position Green suits European enterprises that want a guided path from materiality to a finished ESRS statement.
Where it is strong
- Handles original and revised ESRS as well as VSME
- Fortnox and Microsoft Dynamics 365 connectors
- Carbon accounting and supply chain assessment on the same platform
Watch-outs
- No public pricing
- AutoReporting needs AI enabled and a controller to start it

Workiva
enterpriseWorkiva is a platform companies use to report financial statements, regulatory filings, risk reporting and sustainability disclosure. Its ESG product brings sustainability data into the same controlled environment: data is gathered into the platform, validated where it originates, and linked into reports, so that a figure edited once changes in every document that draws on it.
Framework content sits in the ESG Explorer, which includes prebuilt standards such as GRI, SASB, TCFD and the UN Sustainable Development Goals. A materiality assessment template helps teams decide which topics to cover. Planning, materiality work and drafting of disclosures all happen in one workspace.
All plans come with Workiva's AI companion and its prompt library, version control, comments inside the app, open APIs, round-the-clock phone support and over 70 connectors to systems including Workday, Salesforce and Oracle.
The main reason finance-led teams shortlist Workiva is reuse. Companies already filing SEC reports or annual reports in Workiva can extend the same licence, review process and controls to ESG, which keeps sustainability figures under the discipline applied to financial numbers. Data linking also reduces the risk that a corrected emissions figure appears differently in the report, an appendix and an investor presentation.
Emissions calculation is not the core of the product; its depth depends on carbon data connected from other systems. Workiva publishes no price; its pricing page describes a requirements call followed by a customised demo.
Workiva suits listed companies where finance and sustainability teams want one controlled reporting process. Companies seeking an all-in-one carbon accounting engine may pair it with a specialist tool, as Watershed's Workiva integration illustrates.
Where it is strong
- ESG Explorer ships with SASB, GRI, TCFD and UN SDG frameworks
- Financial, risk and sustainability reports can share one platform
- More than 70 connectors, open APIs and 24/7 phone support in every plan
Watch-outs
- Neither prices nor a plan list are published

Sphera
enterpriseSphera sells software for environment, health, safety and sustainability, and says its products have served over 2,800 customers across three decades. The Corporate Sustainability suite spans collection, disclosure and performance tracking, with modules for reporting, sustainability performance, environmental impact calculation and financed emissions in lending and investment portfolios.
Two content modules distinguish Sphera from software-only vendors. Managed Disclosure Content provides prepared reporting material that shortens the writing of disclosures. Managed LCA Content supplies verified emission factors from Sphera's own life cycle assessment database, and the platform uses them to calculate Scope 3 emissions with industry-specific data rather than generic averages.
Setup effort is reduced through data collection templates and standard configurations based on materiality, so teams start from a prepared structure instead of building one. The software also highlights gaps between targets and actual performance, helping sustainability managers focus attention where progress lags. Expert consulting is offered throughout implementation.
The LCA connection is the strongest reason to choose Sphera. Manufacturers that already run product life cycle assessments or produce environmental product declarations can hold product and corporate sustainability data with one vendor, and use the same factors for both.
Pricing is not published, and the module list is broad, so buyers should scope carefully which modules a quote covers. Sphera suits industrial companies where product footprints and corporate disclosure are closely linked; service businesses without product LCA needs may not use what makes it distinctive.
Where it is strong
- Scope 3 calculations use industry data from Sphera's LCA database
- Consulting experts are available throughout implementation
- Financed emissions module for investment and lending portfolios
Watch-outs
- No public pricing
- A broad module list requires careful scoping

Watershed
enterpriseWatershed presents its product as an AI platform for sustainability, organised around three activities: measuring, reporting and acting. Measurement draws on 2.3 million emission factors along with benchmarks and methodologies, covers water and land use as well as carbon, and keeps every figure traceable to the calculation behind it, which is what assurance providers ask to see.
CSRD support is detailed. Watershed maps a company's materiality assessment onto ESRS requirements, computes the ESRS metrics after data arrives, and applies over 150 automated checks that flag errors before an auditor finds them. Qualitative answers are drafted by AI using peer examples, regulatory guidance and company data, displaying the sources it used so reviewers can verify each statement. The same dataset maps to CDP, TCFD and ISSB, and an integration with Workiva handles XBRL tagging and consolidation for companies that file through that platform.
Acting on the data is the third part. Watershed supports supplier decarbonisation programmes, forecasts at product level, and buying vetted clean power projects, so the platform extends beyond producing the report into reducing the numbers it contains.
Watershed points to leader placements in Verdantix Green Quadrant reports and in Forrester's 2026 Wave for sustainability management software.
No pricing page exists; buyers request a demo. Watershed suits large companies with established sustainability programmes that need audit-ready carbon data, CSRD reporting and supplier engagement in one system.
Where it is strong
- AI drafts qualitative disclosures and shows its sources
- Workiva integration handles XBRL tagging and consolidation
- Measurement covers water and land use as well as carbon
Watch-outs
- No public pricing

Diligent
enterpriseDiligent built its name on board management software, and Diligent ESG extends that governance platform to sustainability data and disclosure. Data arrives through workflows, surveys that can reach thousands of employees and suppliers, and imports. Emissions across all three scopes are calculated with over 70,000 factors that Diligent maintains, and data maps to CDP, GRI, SASB, TCFD and WEF metrics as well as to a company's own internal framework.
CSRD reporting is split into two tools. Instant reports generate the quantitative tables for a selected disclosure requirement and reporting year, with filters for scope or data stream. A separate Diligent ESG Author tool builds the narrative corporate report section by section along ESRS lines, ESRS 2 for example. Diligent also produces the tables required for the CDP climate questionnaire.
According to the help documentation, each account needs the CSRD module switched on by its customer success manager, so buyers should confirm that it is included in any quote.
The governance link is Diligent's main differentiator. ESG data can be presented to directors through storyboards, placing sustainability information in front of the board in the same environment used for board materials. Buyers who already run Diligent board portals or risk products can ask how ESG data links into them.
No prices or plans are published. Diligent suits companies that want sustainability reporting to sit beside board governance and risk oversight with one vendor, particularly where directors are expected to engage directly with ESG performance.
Where it is strong
- Over 70,000 maintained emissions factors for Scope 1, 2 and 3
- Surveys reach thousands of employees and suppliers
- ESG storyboards present data to directors

Questions buyers ask
How long does it take to implement ESG reporting software?
Timelines depend on data sources and framework scope rather than on installation. A free tier such as Persefoni Pro can produce a first carbon inventory quickly because it is self-service. Platforms that connect many systems, such as Enablon's links to over 100 enterprise applications or IBM Envizi's utility and meter analytics, require integration work. Sphera offers expert consulting throughout implementation, which signals the effort involved in larger deployments.
Which vendors publish any pricing information?
Persefoni Pro costs nothing and has no expiry or card requirement, though Advanced and framework report add-ons are quoted. IBM Envizi publishes its structure, three volume bundles measured in Accounts plus add-on modules, but no figures. The other eight vendors, including Workiva, Watershed and Sweep, quote after a demo or scoping call.
Can ESG reporting software replace a separate carbon accounting tool?
Sometimes. Watershed, Persefoni, IBM Envizi, Sphera and Diligent calculate Scope 1, 2 and 3 emissions within the platform. Novisto and Position Green include carbon accounting as a module. Workiva's emissions depth depends on connected carbon data, and Watershed integrates with Workiva for companies that want both. Buyers should compare emission factor libraries, such as Watershed's 2.3 million factors or Diligent's 70,000, against their supply chain.
Which platforms help with assurance and audit?
Watershed applies over 150 automated ESRS checks and keeps figures traceable to their calculations. Novisto provides role-based approvals and an audit trail. Sweep lets reviewers accept or reject individual responses with documents attached. Workiva validates data at the source and links figures across documents. Buyers should ask whether external auditors can receive direct read access.
Who should not buy an enterprise ESG platform?
A small supplier answering a few customer questionnaires usually does not need multi-entity consolidation, XBRL tagging or board storyboards. Persefoni Pro gives carbon accounting and a report builder at no cost, and Position Green handles VSME, the voluntary standard for smaller firms. Workiva, Enablon, Sphera and IBM Envizi are built around large, multi-site reporting.
Which tools cover ISSB and IFRS S1 and S2?
Novisto holds official software-partner status with the IFRS Foundation for S1 and S2, alongside its SASB licence. Watershed and Sweep map data to ISSB, Persefoni offers a paid ISSB metrics report, and Enablon lists IFRS among the standards it conforms to. Companies in jurisdictions that have adopted ISSB locally should confirm support for the local version separately.
How do these platforms handle CSRD double materiality?
Novisto offers an EFRAG-aligned assessment with automatic scoring. Sweep provides a sector-based assessment and a free Materiality Builder that exports a matrix. Position Green starts its CSRD workflow with double materiality, and Watershed maps a company's assessment to ESRS requirements. Enablon and Workiva include materiality assessment tools within broader reporting platforms.
