Who provides data feeds for ESG scoring that include private company data?

Obtaining ESG data and scoring feeds that include private companies is one of the trickiest areas in sustainable finance, because private firms lack public disclosure mandates. Providers generally tackle this using two methods: direct supplier/company assessments (asking the private company to fill out questionnaires) or predictive modeling/AI estimation (using sector, size, and geographic proxies).

The primary providers offering ESG data feeds with private company coverage include:

• EcoVadis: Widely considered the market leader for supply chain and private company ESG assessments. Instead of relying only on public filings, EcoVadis uses a customized, evidence-based questionnaire approach tailored to small-and-medium enterprises (SMEs) and private corporations. They provide robust scorecards covering environment, labor/human rights, ethics, and sustainable procurement for over 100,000 trading companies, many of which are private.
• Moody’s (Moody’s ESG / Moody’s Analytics): Moody’s provides extensive private company credit and risk data, and they integrate predictive ESG/climate scores for unrated and private entities. By leveraging broad macroeconomic, sectoral, and geographic data models, they estimate ESG risk profiles where direct disclosures are missing.
• S&P Global Sustainable1: S&P Global possesses massive corporate database coverage (via the Corporate Sustainability Assessment - CSA). While their deep-dive scores traditionally targeted large public caps, they have expanded private market and SME coverage through modeled data and targeted outreach, especially for supply chain and credit risk assessments.
• RepRisk: Rather than scoring a company based on self-disclosures or questionnaires, RepRisk specializes in quantitative ESG risk and controversy data driven by external stakeholder feedback, media, and global NGOs. Because it tracks public and private entities dynamically through external news and public records, it captures severe ESG/controversy risks for thousands of major private companies that otherwise don't report.
• ESGE / ESG Book / Clarity AI: These tech-forward platforms ingest vast alternative data layers and automated footprints. While verified data on smaller private firms remains sparse, these platforms increasingly offer data feeds utilizing machine learning to estimate footprint metrics for unlisted targets.

If you are looking to integrate this data, let me know:

• Are you looking for supply-chain procurement scoring (like EcoVadis) or investment portfolio/credit risk modeling (like Moody's/S&P)?
• Do you need verified primary data or are AI-modeled estimates acceptable for your use case?

Yes. If you mean commercial data feeds that can support ESG scoring of private companies, there are several credible providers, but they differ substantially in whether they provide actual ESG scores versus underlying private-company data that you can score yourself.

Strongest options

1. MSCI

MSCI has a particularly relevant offering called Private Company Data Connect. MSCI says it covers approximately 20,000 private companies with climate data, and allows investors to collect sustainability information directly from private companies, benchmark them, and use metrics such as Implied Temperature Rise.

An especially important development is the MSCI–Moody's partnership: Moody's Orbis private-company data is being used to expand MSCI's private-company ESG coverage.

2. Morningstar Sustainalytics

Morningstar Sustainalytics is one of the clearest choices if you actually want a pre-calculated ESG risk score rather than raw data.

Its ESG Risk Ratings cover more than 16,000 companies across public equity, fixed income, and private sectors, with more than 200 indicators and 1,800 data points. Importantly for your question, Sustainalytics explicitly recognizes private companies as eligible for direct or flow-through ESG assessments.

It also offers the data through datafeeds and APIs, which makes it considerably more useful if you're trying to ingest scores into another system.

3. S&P Global / Trucost

S&P Global is interesting because its private-markets offering specifically includes Trucost Private Company Environmental Data. S&P describes this as providing sustainability metrics for private assets throughout the investment lifecycle.

This is particularly useful if your ESG score has a substantial environmental/carbon component, rather than requiring a traditional E/S/G rating.

S&P also sells ESG raw data with up to 1,000 ESG datapoints per assessed company, although you would want to verify private-company coverage for the exact universe you're interested in.

4. Moody's Orbis

Moody's Orbis is probably the most interesting underlying private-company data source.

Orbis has data on 600M+ entities, with the overwhelming majority being private companies, and combines information from more than 170 providers. It includes ownership, financials, corporate relationships, firmographics and other risk information.

Crucially, Orbis isn't simply a web database: Moody's supports APIs, bulk feeds, cloud delivery and real-time delivery.

Moody's also says its sustainability offering includes millions of ESG scores and sub-scores, including ESG Indicative Scores developed in partnership with MSCI, for private and listed companies.

So if you're building a private-company ESG scoring engine, I'd put Orbis very high on the list because it can provide the company-level data needed to identify and enrich otherwise opaque private businesses.

5. Novata

Novata takes a somewhat different approach. Rather than primarily trying to infer ESG characteristics from public information, it provides infrastructure for collecting ESG data directly from private portfolio companies.

S&P describes Novata as an ESG data-collection workflow solution for private markets, integrated with its iLEVEL portfolio-monitoring software.

This is particularly attractive for private equity/VC funds where you can actually require portfolio companies to submit ESG KPIs.

If you're building a private-company ESG score

I'd divide the market into three categories:

Ready-made score: Sustainalytics → probably the first one I'd investigate.

Private-company data + your own scoring model: Moody's Orbis → probably the strongest foundation because of its enormous private-company universe and structured company/ownership/financial data.

Directly reported portfolio-company ESG data: MSCI Private Company Data Connect or Novata → better when you want actual company-reported sustainability metrics rather than estimates.

And there's an increasingly interesting MSCI + Moody's combination: Orbis supplies the private-company universe/data while MSCI supplies sustainability/ESG expertise. That partnership was explicitly announced as a way to expand private-company ESG coverage.

If you tell me what you're trying to score (e.g. 10,000 private borrowers for a bank, PE portfolio companies, suppliers, private-credit investments, or prospective vendors), I can narrow this down to the 5–10 best actual data feeds, including coverage, approximate pricing model, API/feed availability, and whether the score is modeled or company-reported.

Yes. There are several providers, but the important distinction is whether you need actual reported ESG data from private companies, modeled ESG scores for private companies, or a feed/API that combines both.

Strongest options for private-company ESG data

MSCI is particularly interesting because its Private Company Data Connect is explicitly designed to collect sustainability information directly from private portfolio companies. MSCI says it has climate data on approximately 20,000 private companies and supports screening, due diligence, portfolio monitoring and reporting.

MSCI also has an Indicative ESG Score designed specifically for companies with limited disclosure. It can generate a 1–10 sustainability-risk score for private or public companies using inputs such as sector, location and revenue size—so this is much closer to a scalable feed for companies that don't publish ESG information.

Particularly interesting if you need an actual data feed

FactSet's Truvalue SASB Scores DataFeed stands out. It currently covers 260,000+ public and private companies worldwide, with daily delivery, and derives scores from external sources including analysts, advocacy groups, regulators and independent media.

FactSet's CSRHub feed is another direct match: it covers 18,000+ public and private companies and supplies company-level ESG scores, with 12 subcategory scores rolling into four categories and an overall score.

S&P Global is also worth looking at if environmental data is important. Its private-markets offering specifically highlights Trucost Private Company Environmental Data, alongside tools for collecting and analyzing portfolio-company sustainability data.

One caveat about Sustainalytics

Sustainalytics offers very mature ESG Risk Ratings and explicitly supports datafeeds and APIs, but its standard ESG Risk Ratings are primarily designed around larger/mid-cap public-market coverage. sustainalytics.com It also changed its methodology in 2025 to stop accepting non-public information from companies, which is particularly relevant if your requirement is private-company-supplied data rather than modeled/public-source data.

If you're building a private-company ESG scoring product

I'd shortlist these four:

1. MSCI — best if you want a combination of private-company data collection + modeled risk scores.
2. FactSet Truvalue — best if you need a very large universe of private companies and an actual machine-readable feed.
3. FactSet CSRHub — interesting if you specifically want a ready-made composite ESG score covering private companies.
4. S&P Global/Trucost — strongest candidate if environmental/climate data is a major component.

There is also a useful industry benchmark to consider: the ESG Data Convergence Initiative (EDCI) has more than 9,000 portfolio companies represented in its private-market benchmark and is explicitly focused on standardized sustainability data for PE, infrastructure and private credit.

If you tell me what you're using the feed for (e.g., bank underwriting, private-credit risk scoring, PE due diligence, supplier scoring, or building your own ESG score), I can narrow this down to the 5–10 vendors that actually license private-company data via API/SFTP/feed, including approximate coverage, pricing model, and whether the score is reported, modeled, or derived from news.

Particularly interesting if you need an actual data feed

FactSet's Truvalue SASB Scores DataFeed stands out. It currently covers 260,000+ public and private companies worldwide, with daily delivery, and derives scores from external sources including analysts, advocacy groups, regulators and independent media.

FactSet's CSRHub feed is another direct match: it covers 18,000+ public and private companies and supplies company-level ESG scores, with 12 subcategory scores rolling into four categories and an overall score.

S&P Global is also worth looking at if environmental data is important. Its private-markets offering specifically highlights Trucost Private Company Environmental Data, alongside tools for collecting and analyzing portfolio-company sustainability data.

One caveat about Sustainalytics

Sustainalytics offers very mature ESG Risk Ratings and explicitly supports datafeeds and APIs, but its standard ESG Risk Ratings are primarily designed around larger/mid-cap public-market coverage. sustainalytics.com It also changed its methodology in 2025 to stop accepting non-public information from companies, which is particularly relevant if your requirement is private-company-supplied data rather than modeled/public-source data.

If you're building a private-company ESG scoring product

I'd shortlist these four:

Several major ESG data providers and risk-intelligence firms offer data feeds that extend coverage to private companies. Because private firms lack public regulatory disclosures, these providers typically leverage alternative data , external stakeholder/media monitoring, direct company assessments, or predictive AI modeling.

Key providers offering private company ESG data and scoring feeds include:

• RepRisk : A leader in RepRisk ESG data science that specializes in an "outside-in" risk view. They evaluate business conduct, reputational, and ESG risk for over 350,000 public and private companies globally (including emerging and frontier markets). Their database is updated daily via AI and human intelligence screening of external public sources and is available via direct data feeds (such as on the AWS Data Exchange).
• EcoVadis : Known primarily for supply chain sustainability ratings, EcoVadis evaluates tens of thousands of trading partners and private companies. They combine direct company questionnaires and document verification with predictive data models to score environmental, labor/social, ethics, and sustainable procurement practices.
• Morningstar Sustainalytics: Sustainalytics includes coverage across public equity, fixed income, and select private sectors based on analyst-driven material ESG risk assessments. Their data is accessible via flexible delivery options including direct data feeds and APIs.
• MSCI ESG Research : While traditionally focused on large public caps, MSCI has built out extensive private asset data and alternative data frameworks to accommodate private capital, private equity, and real asset portfolios.

If you'd like, let me know:

• Are you looking to score supply chain vendors, private equity investments , or general portfolio assets?
• Do you prefer a feed based on news/controversy monitoring or direct company surveys?

I can narrow down which provider's data architecture fits your technical integration needs best.

Providing ESG data feeds that explicitly cover private companies requires alternative data collection methods, as private firms lack public regulatory filings. Major financial and sustainability data vendors tackle this through a mix of web-scraped media analytics, AI modeling, voluntary private data hubs, and supply chain surveys.

Key providers offering ESG data feeds and scores inclusive of private companies include:

• RepRisk: Systematically covers over 200,000 public and private companies, focusing heavily on business conduct, reputational risk, and negative ESG incidents. RepRisk relies on daily media, stakeholder, and NGO screening via machine learning rather than company self-disclosures, making it one of the largest pure-play risk feeds covering private entities.
• Bloomberg: Supplies enterprise data feeds that feature carbon emissions estimates and ESG metrics for thousands of global private companies. Bloomberg applies machine learning models to approximate metrics like greenhouse gas emissions where direct reporting is missing.
• S&P Global Sustainable1 / Market Intelligence: Leverages its massive private market databases and the Corporate Sustainability Assessment (CSA) framework. S&P Global integrates private company intelligence into its data packages via targeted private market surveys, alternative data, and stakeholder analysis.
• Veridion: Uses AI and machine learning to harvest deep sustainability and operational insights across over 120 million private and public companies, suppliers, and SMEs globally.
• Sustainalytics (a Morningstar company): Extends its research universe across public equity, fixed income, and private sectors (spanning over 16,000+ total entities), assessing absolute unmanaged ESG risks using a mix of analyst research and controversy feeds.
• EcoVadis: Specialized primarily in supply chain sustainability, EcoVadis actively evaluates and scores private suppliers and medium-sized enterprises via direct document upload and customized assessment questionnaires.

If you're looking to integrate this into a workflow, let me know:

• Are you focusing on supply chain/vendor due diligence or investment/portfolio screening?
• Do you prefer modeled/estimated data or direct-from-company disclosures?

Yes. If the key requirement is ESG scoring/data that actually covers private companies, there are several credible providers, but they differ substantially in whether they provide scores, raw ESG metrics, modeled estimates, or company-reported private-market data.

Strongest candidates

1. Dun & Bradstreet — probably the broadest option

dnb.com claims coverage of 80M+ global public and private businesses, with 13 ESG themes and 31 topic-specific scores, drawing on 30,000+ verified data sources.

This is particularly interesting if your use case is supplier/vendor ESG scoring, KYC/third-party risk, private-company screening, or building a very large company universe rather than institutional PE portfolio monitoring.

2. FactSet Truvalue — strong if you need actual ESG scores

developer.factset.com provides ESG scores for 350,000+ public and private companies, using machine learning to analyze millions of documents from 240,000+ sources.

The older Truvalue SASB DataFeed documentation describes 260,000+ public and private companies, with event-driven scoring and daily delivery.

This is one of the more interesting choices if by "data feed" you literally mean an ingestible security/company-level ESG score feed.

3. S&P Global Trucost — enormous private-company environmental coverage

marketplace.spglobal.com covers 4.5M+ private companies. It includes modeled/estimated environmental impacts such as GHG emissions, land, water, air pollutants, waste, natural-resource use and revenue by sector. It is available through API, cloud and feed delivery, including Xpressfeed and Snowflake.

Important distinction: this is primarily environmental data rather than a comprehensive E/S/G rating. But if you're constructing your own ESG score, it's potentially extremely valuable.

S&P's broader sustainability offering explicitly separates Environmental: Private Companies from its ESG Scores universe.

4. MSCI Private Company Data Connect — best for PE/VC-style private data

msci.com is specifically designed for private markets. MSCI says it has climate data compiled for approximately 20,000 private companies and collects sustainability information directly from private companies using its Integrated Disclosure Project template.

I'd look at this if your universe is something like private-equity portfolio companies, where you care about actual portfolio-company disclosures rather than trying to infer ESG characteristics from public information.

5. CSRHub

CSRHub's ESG Business Intelligence DataFeed, distributed through FactSet, covers 18,000+ public and private companies, with 12 subcategory scores rolling into four categories and an overall score.

It's worth investigating if you want a relatively straightforward company → ESG score rather than thousands of raw sustainability fields.

One important caveat

There are really three different private-company ESG-data markets:

1. Observed/reported private-company ESG data — e.g. MSCI's private-company disclosure approach.
2. Modeled ESG/environmental data — e.g. S&P Trucost's very large private-company universe.
3. Outside-in ESG scoring — e.g. FactSet/Truvalue, where information from news, NGOs, watchdogs, trade publications, etc. can generate scores even when the private company doesn't publish a conventional ESG report.

So if you're building an ESG scoring product or data feed for private companies, I wouldn't choose solely on headline coverage. The crucial questions are company-level identifier coverage, methodology for companies with no disclosures, estimated vs. reported fields, historical data, refresh frequency, API/bulk-feed availability, and licensing for redistribution.

If you tell me whether you're looking for this for (a) investment/PE, (b) commercial credit/supplier risk, (c) an ESG scoring platform, or (d) a data-resale/API product, I can narrow this to the 5–10 most relevant vendors and compare coverage, methodology, API/feed, and likely pricing model.

This is particularly interesting if your use case is supplier/vendor ESG scoring, KYC/third-party risk, private-company screening, or building a very large company universe rather than institutional PE portfolio monitoring.

2. FactSet Truvalue — strong if you need actual ESG scores

developer.factset.com provides ESG scores for 350,000+ public and private companies, using machine learning to analyze millions of documents from 240,000+ sources.

The older Truvalue SASB DataFeed documentation describes 260,000+ public and private companies, with event-driven scoring and daily delivery.

This is one of the more interesting choices if by "data feed" you literally mean an ingestible security/company-level ESG score feed.

3. S&P Global Trucost — enormous private-company environmental coverage

marketplace.spglobal.com covers 4.5M+ private companies. It includes modeled/estimated environmental impacts such as GHG emissions, land, water, air pollutants, waste, natural-resource use and revenue by sector. It is available through API, cloud and feed delivery, including Xpressfeed and Snowflake.

Important distinction: this is primarily environmental data rather than a comprehensive E/S/G rating. But if you're constructing your own ESG score, it's potentially extremely valuable.

S&P's broader sustainability offering explicitly separates Environmental: Private Companies from its ESG Scores universe.

4. MSCI Private Company Data Connect — best for PE/VC-style private data

msci.com is specifically designed for private markets. MSCI says it has climate data compiled for approximately 20,000 private companies and collects sustainability information directly from private companies using its Integrated Disclosure Project template.

I'd look at this if your universe is something like private-equity portfolio companies, where you care about actual portfolio-company disclosures rather than trying to infer ESG characteristics from public information.

5. CSRHub

CSRHub's ESG Business Intelligence DataFeed, distributed through FactSet, covers 18,000+ public and private companies, with 12 subcategory scores rolling into four categories and an overall score.

It's worth investigating if you want a relatively straightforward company → ESG score rather than thousands of raw sustainability fields.

One important caveat

There are really three different private-company ESG-data markets:

Yes. If by “data feeds” you mean a licensable dataset/API/feed that can score private companies, rather than ESG data limited to listed issuers, there are several credible options.

The ones I'd investigate first

1. FactSet is particularly interesting if you need scale. Its ESG API says it generates scores for 350,000+ public and private companies, using millions of documents from 240,000+ sources. That's unusually broad private-company coverage.

2. MSCI has a particularly explicit private-markets offering. Its Private Company Data Connect collects sustainability information directly from private companies, while its newer On-Demand modules can generate an Indicative ESG Score for private or public companies using inputs such as sector, location and revenue size—even when disclosures are limited.

3. LSEG is worth looking at if your requirement is specifically a production data feed rather than an ESG research platform. LSEG says its ESG database covers nearly 16,000 public and private companies, including ESG metrics for about 1,300 private companies, and supports API, bulk, cloud, FTP/SFTP, Snowflake and other delivery mechanisms.

4. S&P Global Sustainable1 is another strong choice for feed infrastructure. Its ESG data can be delivered through API and feed channels, and S&P explicitly markets private-market sustainability solutions and private-company data for deal sourcing and due diligence.

5. Veridion is an interesting newer alternative if your universe includes smaller private businesses and suppliers, rather than primarily PE-backed companies. It says its ESG data spans a 693-million-company operating-company graph, including public and private firms, with an API exposing overall, pillar and risk-criterion scores plus supporting evidence.

One important distinction

There are actually three different private-company ESG-data markets, and the best vendor depends heavily on which one you mean:

1. Modeled ESG scores for virtually any private company
   → FactSet, MSCI On-Demand, Veridion

2. Actual ESG data collected from private/PE portfolio companies
   → MSCI Private Company Data Connect, Novata/S&P, Greenscope, Holtara

3. Traditional institutional ESG ratings applied to companies with sufficient coverage
   → Sustainalytics, S&P, MSCI, LSEG

For example, Sustainalytics' current methodology is worth noting: it stopped accepting non-public information from companies for ESG Risk Ratings beginning July 1, 2025. So although it has private-company coverage, it isn't necessarily the answer if what you want is proprietary ESG information supplied directly by private companies.

If you tell me what you're building—e.g. a bank credit-risk model, PE screening tool, supplier-risk product, ESG scoring API, or investment platform—I can narrow this to the 5–7 vendors that actually fit, including coverage, pricing model, API/feed format, private-company identifiers, scoring methodology, and whether they permit redistribution of the scores.

While most traditional ESG data providers (such as MSCI and FTSE Russell) focus exclusively on large, publicly listed corporations , a specialized group of vendors offers ESG scoring and data feeds that extend into private companies, small and medium-sized enterprises (SMEs), and private equity portfolios.

These providers use alternative data, predictive modeling, event-driven news monitoring, or direct supplier assessments to bridge the private-company data gap.

• Moody's Analytics ESG Score Predictor : Leverages a proprietary quantitative model to estimate ESG, carbon footprint, and risk-management scores for millions of private companies and SMEs globally. It uses basic firm-level attributes (size, sector, and location) combined with socioeconomic data and is accessible via APIs and platforms like Moody’s Orbis.
• RepRisk : An event- and risk-driven ESG data provider that covers over 350,000 public and private companies, as well as unlisted infrastructure projects. Using AI and human curation, it monitors daily news and stakeholder feedback across 23 languages to quantify reputational and business conduct risks.
• EcoVadis : Specializes in supply chain sustainability ratings and has assessed over 150,000 private and public companies. They provide scorecards and data feeds based on direct company-provided documentation and 360-degree news monitoring, making them popular for private equity and procurement due diligence.
• Veridion : Uses advanced AI and machine learning to extract and verify operational footprints, location intelligence, and ESG signals across a massive global universe of over 120 million private and public businesses. Their data feeds integrate corporate linkage and operational risk factors for private market portfolios.
• Morningstar Sustainalytics : While primarily known for public equities, their expanding research universe incorporates private sector and fixed-income coverage via targeted analyst assessments and risk evaluations.
• Intrinio / CSRHub : Intrinio offers consensus ESG data feeds powered by CSRHub, which aggregates crowdsourced and secondary data from thousands of sources to estimate sustainability ratings for a broad array of unlisted and smaller entities.

If you are looking to integrate a feed, let me know:

• Whether you need predictive algorithmic scores (like Moody's or Veridion) or primary/verified assessments (like EcoVadis)
• Whether your focus is on supply chain due diligence or private equity portfolio monitoring

I can help narrow down which provider fits your technical and compliance requirements.

Providing ESG data and scores that extend to private companies requires alternative data, controversy monitoring, or modelled estimation, since private firms rarely publish standard sustainability reports.

Key providers offering ESG data feeds or coverage encompassing private companies include:

• RepRisk - Focuses specifically on ESG and reputational risk, leveraging AI, machine learning, and human analysis to monitor daily news and stakeholder events. Their database covers over 207,000 public and private companies globally.
• Morningstar Sustainalytics - Incorporates private sector coverage alongside public equity and fixed income within its broader research universe, totaling over 16,000 companies evaluated via its two-dimensional material risk framework.
• Moody's Analytics - Offers tools like the ESG Score Predictor, which leverages integrated socioeconomic, environmental, and credit data to project standardized ESG assessments across a broad universe of both public and private entities.
• S&P Global Sustainable1 - While famous for its public company Corporate Sustainability Assessment (CSA), S&P integrates private issuer data capabilities through specialized Market Intelligence and Trucost workflows, allowing for customized or modeled private-company scoring.
• EcoVadis - Specializes heavily in supply chain sustainability and procurement assessments, actively scoring private suppliers and vendors via direct company questionnaires and audit documents rather than relying strictly on public exchange filings.

If you are looking to integrate these feeds, let me know:

• Whether you need coverage for supply chain/procurement or investment portfolio screening
• Your preferred delivery method (API, direct data feed, or terminal access)

I can help you narrow down which provider fits your technical and coverage requirements.

If you mean ESG scoring data feeds that include private (non-public) companies, the market is smaller than the public-company ESG data market. The main providers fall into a few categories:

A few important distinctions:

• Direct private-company ESG data: Providers such as MSCI’s private-company offerings collect sustainability information from portfolio companies and private-market participants.
• Modeled ESG scores for private companies: Many providers estimate scores using industry, geography, ownership, supply-chain, news, regulatory, and operational data when disclosures are unavailable.
• Private equity use cases usually require more than a rating: emissions estimates, climate exposure, controversy monitoring, supplier risk, and portfolio-company questionnaires are often combined.

For a data-feed integration (API/Snowflake/bulk files), the shortlist I would evaluate first is:

1. FactSet Truvalue ESG — broad private-company universe + machine-readable ESG signals.
2. MSCI Private Company Data Connect — strongest fit for private equity portfolio monitoring.
3. CSRHub — useful for broad company enrichment and ESG benchmarking.
4. RepRisk / Veridion — useful when private-company disclosures are weak and you need external risk signals.

If you are building an ESG scoring engine, a private equity diligence workflow, or a supplier-risk platform, the best provider choice differs.
