What Conflicts of Interest Exist in the ESG Rating Industry?

The ESG rating industry faces conflicts of interest analogous to — and in some ways more severe than — the conflicts that plagued credit rating agencies before the 2008 financial crisis. When the same organization that rates a company's ESG quality also sells consulting services to help that company improve its ESG scores, or when a company can pay to have its ratings re-reviewed, the independence of the rating is compromised. Understanding these conflicts helps investors evaluate whether ESG ratings reflect independent assessments or commercial relationships.

Quick definition: ESG rating conflicts of interest arise when business relationships between ESG rating agencies and the companies they rate create financial incentives that could influence rating outcomes — either inflating ratings for paying clients or creating commercial pressure to avoid negative assessments.

Key takeaways

• The primary ESG rating conflict of interest is the "issuer feedback" model, where companies can submit information to rating agencies to influence their ratings — creating commercial incentives for rating agencies to maintain positive relationships with rated companies.
• Some ESG rating agencies sell consulting or advisory services alongside rating services to the same companies they rate, creating a direct issuer-pays conflict.
• Unlike credit ratings (where SEC regulations require registered credit rating agencies to manage conflicts of interest), ESG ratings were largely unregulated until the EU's ESG Rating Regulation (2024) and similar regulatory developments.
• The conflict of interest problem is more acute for questionnaire-based rating systems (where company responses directly determine scores) than for independently derived assessments based on third-party data.
• Regulatory reform — requiring ESG rating agencies to separate rating and consulting activities — is the primary structural solution, as has been implemented in the EU.

The Issuer Feedback Model

Most major ESG rating agencies provide companies with feedback on their ratings before publication — sharing draft scores, the factors affecting them, and the data underlying their assessments. This process is intended to allow companies to correct factual errors. But it also creates structural tension:

The commercial relationship dynamic: ESG rating agencies are businesses that depend on subscriber fees from investors — but they also have commercial relationships with rated companies, who may subscribe to data products, attend conferences, or engage advisory services. A rating agency that consistently produces negative assessments of companies it wants to maintain commercial relationships with faces commercial pressure.

The "improvement recommendations" pathway: Some ESG rating agencies provide rated companies not only with their scores but with guidance on how to improve them — which data points to disclose, which policies to adopt. This creates a feedback loop where companies optimizing their scores receive guidance from the same agency that will benefit commercially from maintaining the company relationship.

Differential access: Companies that pay for enhanced ESG consulting services or premium data subscriptions may receive more detailed score guidance than companies that don't — creating a pay-to-play dynamic that gives well-resourced companies an advantage in their ESG scores regardless of underlying performance.

Consulting and Advisory Conflicts

Several ESG rating agencies have offered consulting or advisory services to rated companies:

Score improvement consulting: Some providers have offered (or historically offered) services explicitly designed to help companies improve their ESG scores — which creates an obvious conflict when the same organization provides both the consulting advice and the subsequent rating.

ESG strategy advisory: Broader ESG strategy advisory services — helping companies set ESG targets, design programs, structure governance — when offered by a rating agency create a relationship where the advisor has financial incentive to produce ratings that validate the strategy it recommended.

DJSI consulting history: S&P Global's CSA/DJSI has historically faced scrutiny about whether companies could purchase consulting services that helped them qualify for DJSI inclusion, with the same organization providing both assessment and consulting. S&P has taken steps to separate these functions.

Conflict of interest sources

Comparison to Credit Rating Agency Conflicts

The credit rating industry faced analogous conflict of interest problems that contributed to the 2008 financial crisis. Structured finance products (CDOs, mortgage-backed securities) received investment-grade ratings from agencies that were paid by the product issuers — creating incentives to provide favorable ratings to maintain issuer business. Dodd-Frank and SEC regulations subsequently required credit rating agencies to disclose and manage conflicts of interest.

ESG ratings have faced similar structural problems but with less regulatory attention until recently:

Similarities: Issuers (companies) and raters have commercial relationships; rating agencies depend on revenue from rated entities or their investors; positive ratings maintain relationships.

Differences: ESG ratings are opinions about multi-dimensional ESG performance rather than narrow probability assessments (credit ratings); the financial consequences of inflated ESG ratings are less immediately catastrophic than inflated credit ratings on securitized products; ESG ratings users (investors) are more sophisticated than typical fixed income investors who may not question credit ratings.

EU ESG Rating Regulation (2024)

The EU's ESG Rating Regulation, published in 2024 and taking effect from 2026 for firms with EU operations, addresses conflicts of interest directly:

Prohibition on consulting services: ESG rating agencies subject to the regulation are prohibited from providing consulting or advisory services to rated companies — requiring structural separation of rating and consulting activities.

Transparency requirements: Firms must disclose their methodologies, data sources, and any material conflicts of interest.

Registration and supervision: ESG rating providers serving EU investors must register with ESMA (European Securities and Markets Authority) and are subject to ongoing supervisory oversight.

Independence requirements: The regulation requires organizational structures that protect rating functions from commercial pressure.

This represents the first comprehensive regulatory framework for ESG rating independence and is likely to influence global standards for the industry. Readers should verify current implementation details at esma.europa.eu as the regulation is implemented.

How Investors Can Assess Rating Independence

Methodology transparency: Rating agencies with fully transparent, publicly documented methodologies are less able to apply subjective judgments that favor commercial relationships. Opacity in methodology is a flag for potential conflicts.

Separation of rating and consulting: Agencies that maintain structural separation between rating and consulting functions — different staff, different P&L, different client relationships — are less conflicted than those that combine them.

Revenue mix analysis: Does the agency derive most of its revenue from investor subscriptions (investor-pays model) or from issuer-related services (issuer-pays model)? Investor-pays models have stronger independence incentives.

Multiple provider use: Comparing ratings from multiple providers with different business models reduces dependence on any one provider's potential conflicts. If several independent providers agree on a company's ESG quality, the risk that a single provider's conflict has distorted the picture is reduced.

Real-world examples

ISS separation of proxy and ESG services: ISS has developed structures to separate its proxy advisory business from its ESG ratings business — different client teams, different revenue streams, and governance firewalls to prevent the company-relations aspects of proxy advice from influencing ESG rating decisions. This structural separation is a model for conflict management, though its effectiveness depends on organizational culture and governance.

PRI signatory reporting conflict: The UN PRI requires its signatories (investment managers) to complete annual transparency reports — and PRI itself assesses signatories' compliance. PRI has a commercial incentive to maintain signatory relationships (membership dues revenue) while also acting as assessor of signatory quality — a structural tension that PRI has attempted to manage through independent assessment processes.

Academic research on rating agency conflicts: Several academic studies have found that ESG raters give more favorable ESG assessments to companies that are more engaged with the rating process — potentially reflecting a commercial relationship effect. The most directly relevant is Koundouri et al.'s research suggesting that company ESG score improvements do not necessarily reflect genuine ESG improvement.

Common mistakes

Assuming that payment for ESG rating data implies rating independence: Investor-side subscription payments (investors paying for ESG data) do not guarantee rating independence — but they create better independence incentives than issuer-side payments (companies paying for services that influence their ratings).

Dismissing all ESG ratings as conflicted: Conflicts of interest do not make ESG ratings worthless. They make them less reliable in specific circumstances and for specific rating dimensions. Critical use of ESG ratings — with awareness of where conflicts could plausibly distort outcomes — is more productive than wholesale rejection.

Ignoring regulatory developments: ESG rating regulation is developing rapidly in Europe. Firms that operate in or serve EU markets need to understand how the EU ESG Rating Regulation affects their ESG data providers' independence structures and what disclosures they are required to make.

FAQ

Are credit rating agencies also ESG rating agencies?

Major credit rating agencies (Moody's, S&P, Fitch) have all developed ESG assessment products. S&P Global ESG is perhaps the most significant. These firms face the same conflict-of-interest considerations as standalone ESG raters, plus the additional complication that their core credit rating business has established commercial relationships with rated entities that could influence ESG assessments.

What is the investor-pays model in ESG ratings?

In an investor-pays model, ESG rating data is sold to investment managers, pension funds, and other institutional investors who pay for access. The rated companies do not directly pay for their ratings. This model reduces the direct issuer-pays conflict, though indirect conflicts can still arise if rating agencies seek to maintain good relationships with major issuers to ensure questionnaire participation.

What does "structural separation" mean in ESG rating regulation?

Structural separation means organizational, financial, and personnel separation between rating activities and consulting activities at the same firm. The EU ESG Rating Regulation requires firms to ensure that ESG rating analysts are not involved in commercial relationships with rated companies, that compensation structures don't incentivize favorable ratings for commercial clients, and that governance structures protect rating independence from commercial pressure.

How does the PRI manage its own conflicts of interest?

PRI has a structural tension as both a promoter of responsible investment (with incentive to maintain large signatory numbers for influence) and an assessor of signatory quality. PRI attempts to manage this through its Assessment framework (which uses standardized scoring to reduce subjective assessment), its separate Assessment Review Committee, and its stated policy of removing signatories that consistently fail to demonstrate responsible investment practice.

Is ESG rating conflict of interest a bigger problem than credit rating conflict of interest?

The consequences are different. Credit rating conflicts led directly to the inflation of ratings on financial products that subsequently collapsed, with catastrophic consequences for the financial system. ESG rating conflicts primarily lead to inflated ESG scores for companies that manage the rating process well, causing investors to hold companies with worse-than-reported ESG quality. This is a significant problem for ESG investment integrity but has different systemic risk implications than the 2008 structured finance rating failures.

Summary

ESG rating agencies face conflicts of interest arising from commercial relationships with rated companies — the issuer feedback model, consulting service sales, and questionnaire participation revenues. Unlike credit rating agencies, which have been regulated for conflict management since Dodd-Frank, ESG rating agencies faced minimal regulation until the EU's 2024 ESG Rating Regulation, which prohibits consulting services to rated companies and requires methodology transparency and ESMA registration. Investors can partially mitigate conflict risk by using multiple providers, preferring investor-pays revenue models, and checking methodology transparency. Rating independence is an ongoing concern as the industry develops regulatory structures appropriate to its significance in institutional investment decision-making.
