Best ESG Reporting Software (2026): Top 10 Compared

Updated September 2026By StatWharf Editorial10 vendorsMethodology

ESG reporting software collects environmental, social and governance data from across a company, calculates metrics such as greenhouse gas emissions, maps them to disclosure frameworks and produces a report that an auditor can review. The ten products below fall into three groups. Workiva, Diligent and Enablon connect ESG disclosure to financial reporting, board governance or EHS systems. Novisto, Sweep and Position Green are sustainability reporting platforms built around CSRD, ISSB and GRI disclosures. Persefoni, Watershed, Sphera and IBM Envizi start from carbon and environmental data and extend into full reporting. Persefoni is the only vendor here with a free plan, and IBM Envizi is the only one that publishes how its price bands are sized.

These comparisons draw on public product information, not hands-on testing of every tool. Source records identify available references and checks; missing evidence is marked. Buyer fit is an editorial assessment, not a measured performance score. How to use this research.

ESG reporting software turns scattered sustainability data into a disclosure that regulators, investors and auditors can rely on. It gathers energy, emissions, workforce and governance data from business systems and contributors, applies calculation methods such as the GHG Protocol, maps each datapoint to frameworks like CSRD, ISSB, GRI and CDP, and keeps the evidence and approvals behind every number.

The ten products compared here split by origin. Workiva, Diligent and Enablon extend financial reporting, board governance or EHS platforms into ESG. Novisto, Sweep and Position Green are built around multi-framework and CSRD disclosure. Persefoni, Watershed, Sphera and IBM Envizi began with carbon and environmental data and now produce full reports.

Vendor details and trade-offs

Workiva

enterpriseworkiva.com ↗
Consider forFinance and sustainability teams at listed companies that want ESG reports prepared with the same controls and linked data as financial filings, as Workiva describes on its ESG software page
Pricing notesNo published price. Workiva's pricing page describes a sales call to discuss requirements followed by a customised demo, and lists features included with every plan, such as 24/7 support and 70+ connectors, but no figures (checked Sep 2026)
Feature to evaluateData linking keeps one figure consistent across the ESG report, supporting spreadsheets and presentations

Workiva is a reporting platform used for financial statements, regulatory filings, risk and sustainability disclosure. Its ESG product applies the same controlled environment to sustainability data: data is collected into the platform, validated at the source and linked into the report so that a change in one place updates every document that uses the figure.

The ESG Explorer holds pre-built frameworks and standards, including SASB, GRI, TCFD and the UN Sustainable Development Goals, and Workiva offers a materiality assessment template for teams deciding which topics to report. Planning, materiality work and disclosure drafting all sit in the same workspace.

Every plan includes the Workiva AI companion with a prompt library, in-app comments and version control, more than 70 connectors to systems such as Oracle, Salesforce and Workday, open APIs and 24/7 phone support. Buyers already using Workiva for SEC or annual reporting can extend the same licence and review process to ESG, which is the main reason finance-led teams shortlist it.

Potential strengths

  • ESG Explorer offers pre-built SASB, GRI, TCFD and UN SDG frameworks
  • Same platform can hold financial, risk and sustainability reports

Trade-offs

  • No published price or plan list
  • Emissions calculation depth depends on connected carbon data

Diligent

enterprisediligent.com ↗
Consider forCompanies that want ESG data collection, emissions and CSRD reporting on the same vendor platform as board and risk governance, as Diligent documents for Diligent ESG
Pricing notesNo published price. Diligent does not list plans or figures for Diligent ESG; its help documentation states that the CSRD module must be activated for an account through the customer success manager (checked Sep 2026)
Feature to evaluateCSRD instant reports for quantitative datapoints plus a separate author tool for ESRS narrative

Diligent is best known for board management software, and Diligent ESG extends its governance platform into sustainability data and disclosure. The product collects data through workflows, surveys and imports, calculates Scope 1, 2 and 3 emissions using more than 70,000 emissions factors that Diligent keeps current, and maps data to SASB, GRI, TCFD, CDP and WEF metrics as well as an internal framework.

CSRD reporting runs in two parts. Instant reports produce the quantitative tables for a chosen disclosure requirement and reporting year, filtered by scope or data stream. The Diligent ESG Author tool builds the qualitative corporate report, organised by ESRS sections such as ESRS 2. Diligent also generates the tables needed for the CDP climate questionnaire.

For boards, Diligent presents ESG data in storyboards for directors. Buyers already using Diligent for board portals or risk should ask how ESG data connects to those modules and which CSRD features require the extra module.

Potential strengths

  • More than 70,000 emissions factors maintained for Scope 1, 2 and 3
  • Surveys collect data from thousands of employees and suppliers

Trade-offs

  • CSRD is a separately activated module
  • No published pricing model

Persefoni Advanced is aimed at enterprise sustainability programmes. It adds market-based accounting for renewable energy, more granular emission factors, proprietary and custom factors, APIs and an integration hub, reduction modelling and unlimited collaboration seats. Persefoni states that the platform is SOC 2 compliant.

Framework-ready outputs are sold as GHG Metrics Reports: a methodology report and metrics reports for CDP, UK SECR, California's climate disclosure laws, ISSB and CSRD. Buyers should price these add-ons early, since they are where the free tier stops.

Potential strengths

  • Free Pro tier includes Scope 1, 2 and 3 accounting and a report builder
  • Advanced adds reduction modelling, APIs and custom emission factors

Trade-offs

  • Framework report outputs are paid add-ons
  • Broader social and governance reporting is lighter than carbon coverage

How to choose a vendor

Start from the frameworks the company must file

A company under the CSRD needs a double materiality assessment, ESRS datapoints and digital tagging. A US or Australian filer may need ISSB-based climate disclosure, and a supplier answering customers may only need CDP and a GHG inventory. Buyers should list mandatory and voluntary frameworks first, then ask each vendor to show those templates in a live product rather than on a roadmap.

Decide where carbon accounting lives

Several platforms here calculate Scope 1, 2 and 3 emissions themselves, while others import emissions from a separate carbon tool. Running both in one system avoids reconciling two numbers, but a specialist carbon platform may offer deeper emission factor libraries. Buyers should confirm how emissions flow into the report and who owns the calculation audit trail.

Plan for assurance, not only the first report

CSRD and several national regimes require limited assurance, moving towards reasonable assurance. Buyers should ask how each platform records evidence, approvals and changes to a datapoint, and whether external auditors can be given read access. Features that shorten the audit, such as validation checks and data lineage, often matter more in year two than drafting speed in year one.

Frequently asked questions

What is ESG reporting software?

ESG reporting software collects environmental, social and governance data from across a company and its suppliers, calculates metrics such as Scope 1, 2 and 3 emissions, maps the data to frameworks such as CSRD, ISSB, GRI, SASB and CDP, and produces disclosures with an audit trail. Most products also support materiality assessments and review and approval workflows.

How much does ESG reporting software cost?

Among the ten vendors on this page, only Persefoni publishes a figure: its Pro carbon accounting tier is free, while Advanced and framework-specific report add-ons are quoted. IBM Envizi publishes its pricing structure, with bundles sized by the number of data Accounts, but not the prices. The other eight vendors quote after a demo or scoping call.

What is the difference between ESG reporting software and carbon accounting software?

Carbon accounting software calculates greenhouse gas emissions using activity data and emission factors. ESG reporting software covers the full disclosure, including social and governance metrics, narrative sections, materiality and assurance evidence. Several vendors here, such as Watershed, Persefoni, Sphera and IBM Envizi, began with carbon or environmental data and added reporting, while Workiva and Novisto began with disclosure.

Which ESG reporting software supports CSRD and ESRS?

All ten vendors describe CSRD support. Sweep, Novisto, Position Green and Watershed document double materiality, ESRS datapoint collection and report assembly in detail. Sweep and Novisto describe digital tagging for filing, and Watershed integrates with Workiva for XBRL tagging. Diligent's CSRD capability is a separately activated module.

Which tools support ISSB and IFRS S1 and S2 reporting?

Novisto is an official IFRS Foundation software partner and supports IFRS S1 and S2 alongside SASB industry standards. Sweep and Watershed map data to ISSB disclosures, Persefoni sells an ISSB GHG metrics report, and Enablon lists IFRS among its supported standards. Buyers should confirm local adoptions such as the Australian standards separately.

What is a double materiality assessment?

Double materiality is the CSRD test for which sustainability topics a company must report. It considers both how sustainability issues affect the company's finances and how the company affects people and the environment. A topic material under either view is reported. Sweep, Novisto, Position Green and Watershed include assessment tools that link results to ESRS disclosure requirements.

Can a small company use ESG reporting software?

Yes, though most products here target mid-sized and large companies. Persefoni Pro offers free carbon accounting and a report builder for companies with simpler operations. Position Green supports the voluntary VSME standard intended for smaller companies. Enterprise platforms such as Workiva, Enablon, Sphera and IBM Envizi are designed for large, multi-entity reporting.

How were these ESG reporting software vendors selected?

The page includes vendors whose products collect ESG data and produce framework-aligned sustainability disclosures, each with a live product page and a documentation or pricing page checked in September 2026. Order follows source readiness and content sequence, not quality. Vendors not listed can contact [email protected].
