ESMA's New ESG Communication Rules: What 'Integration' and 'Exclusions' Actually Mean Now
The EU regulator is closing the definition gap that let fund managers call almost anything "ESG." Here's what changes for asset managers, LPs, and portfolio companies.
Risk Matrix
Executive Summary
On January 14, 2026, ESMA published its second thematic note on sustainability-related claims, targeting two of the most widely used and loosely defined terms in fund marketing: "ESG integration" and "ESG exclusions." The guidance does not create new law but establishes supervisory expectations that will shape enforcement across EU national regulators.
The context matters. An ESMA study of the 25 largest EU asset managers (EUR 7.5 trillion AUM) found that 64% of funds with ESG-related names changed those names following the May 2025 deadline for fund naming guidelines. Of those that changed, around half replaced explicit ESG terminology with vaguer terms like "Scored," "Screened," or "Select." The message: many funds could not substantiate their original ESG claims.
For asset managers, LPs conducting due diligence, and portfolio companies marketing sustainability credentials, this guidance signals a tightening definitional environment. The era of claiming "ESG integration" without specifying what that integration actually changes in portfolio construction is ending.
The Signal
ESMA's January 14 publication is one component of a broader regulatory tightening on ESG claims:
This thematic note follows ESMA's December 2025 study documenting the market impact of its fund naming guidelines and a first thematic note on ESG credentials. The pattern suggests ESMA is building a comprehensive framework piece by piece, with enforcement likely to follow once supervisory expectations are fully documented.
What Happened
| Date | Event | Significance |
|---|---|---|
| May 2024 | ESMA publishes final fund naming guidelines | 80% threshold, PAB exclusions established |
| Nov 2024 | Guidelines enter into force | Six-month compliance period begins |
| May 2025 | Fund naming deadline | 64% of ESG funds rename; 56% update investment policies |
| Nov 2025 | European Commission publishes SFDR 2.0 proposal | New product categories, 70% thresholds proposed |
| Dec 2025 | ESMA publishes fund naming impact study | Documents mass renaming across EUR 7.5T AUM |
| 14 Jan 2026 | ESMA publishes thematic note on ESG strategies | Do's and don'ts for integration and exclusion claims |
Key Actors
The Core Guidance
ESMA's thematic note establishes four principles for sustainability claims: they must be accurate, accessible, substantiated, and up to date. The guidance identifies specific forms of misleading claims:
"Misleading claims can in particular take the form of cherry-picking, exaggeration, omission, vagueness, inconsistency, lack of meaningful comparisons or thresholds, misleading imagery or sounds."
ESMA Thematic Note, January 14, 2026
ESG Integration Claims
ESMA guidance requires managers to explain:
- → Whether integration is binding or non-binding
- → Where integration sits in the investment process
- → Whether it leads to concrete portfolio action
- → Methodology specifics, not just labels
ESG Exclusion Claims
Investors must be able to see:
- → Precisely what is excluded and why
- → Clear criteria and thresholds
- → Whether screens are based on materiality assessment
- → Whether exclusions have meaningful impact on the portfolio
Market Impact
The study found that approximately half of funds that dropped ESG names replaced them with terms like "Scored," "Screened," "Select," "Advanced," or "Committed." These terms carry less stringent requirements under ESMA guidelines, suggesting the original ESG claims may not have been substantiated.
Article 9 Fund Flows
Article 9 ("dark green") funds have experienced outflows for eight consecutive quarters, with EUR 7.1 billion in redemptions in Q3 2025 alone. Approximately 40% of Article 9 funds by AUM have been downgraded to Article 8 since SFDR inception.
Article 8 Fund Flows
Article 8 funds attracted EUR 75 billion in Q3 2025, the highest since Q4 2021. The divergence suggests investors are shifting to lower-commitment ESG products where greenwashing risk is perceived as lower.
What's Being Overstated
Separating signal from noise:
- • Enforcement Imminent: Only one NCA has taken enforcement action to date. ESMA's supervisory approach currently emphasizes escalated measures over formal enforcement. The immediate risk is reputational, not legal.
- • New Requirements: The thematic note does not create new disclosure requirements. It reminds market participants of existing obligations to make claims that are "clear, fair and not misleading." The guidance applies to non-regulatory oral and written communications.
- • SEC Alignment: The SEC withdrew its proposed ESG disclosure rule in June 2025, and recent US enforcement (WisdomTree, October 2024) suggests a narrower focus on factual misstatements rather than definitional ambiguity. EU and US approaches are diverging.
- • Immediate Deadlines: SFDR 2.0 is not expected until 2028. The current guidance shapes supervisory practice but does not trigger immediate compliance requirements beyond the existing fund naming deadline.
Why It Matters
The guidance addresses a documented market problem. According to an EY survey, 85% of investors report greenwashing is a greater problem than five years ago. A separate study found 25% of retail investors who abandoned ESG cited "too much greenwashing" as the reason, with another 21% citing "general confusion."
Definitional Tightening
The era of claiming "ESG integration" without specifying whether it is binding, where it sits in the process, or whether it affects portfolio construction is ending. ESMA expects specificity.
LP Due Diligence Standard
For LPs conducting manager selection, this guidance provides a reference framework for evaluating ESG claims. The questions ESMA expects managers to answer are the questions LPs should be asking.
Research by Urgewald and Facing Finance found over 4,700 ESG funds traded in European markets invested more than EUR 123 billion in companies "actively pushing fossil fuel expansion projects." The definition gap has real portfolio consequences.
What's Coming: SFDR 2.0
The European Commission's November 2025 proposal for SFDR 2.0 signals the direction of travel. The revision shifts from a disclosure regime to a product categorization regime with three new categories:
| Category | Focus | Threshold | Key Requirements |
|---|---|---|---|
| Transition (Art. 7) | Companies shifting toward sustainability | 70% | CTB-aligned benchmarks, credible transition plans |
| ESG Basics (Art. 8) | ESG integration beyond risk management | 70% | Best-in-class, ESG outperformance targets |
| Sustainable (Art. 9) | Already contributing to sustainability goals | 70% | Climate mitigation, biodiversity, social outcomes |
Only products qualifying under these categories will be permitted to use sustainability-related terms in names or promotional materials. The removal of the current Article 2(17) "sustainable investment" definition and the "Do No Significant Harm" principle suggests a simplification, but also a potential tightening of what can be marketed as sustainable.
Client Implications
PE/VC Firms
Exposure: LP reporting on ESG integration now requires specificity. Vague claims in fundraising materials create regulatory and reputational risk.
Opportunity: Firms with documented, binding ESG processes can differentiate as LP due diligence tightens.
Risk: "Check-the-box" ESG diligence may fail to identify greenwashing risk in portfolio companies, exposing GPs to LP scrutiny.
Family Offices
Exposure: ESG fund allocations may not deliver expected sustainability outcomes if underlying integration is non-binding.
Opportunity: Apply ESMA's framework when evaluating manager ESG claims. Ask: Is integration binding? Does it affect the portfolio?
Risk: Reputational exposure if allocated funds are subsequently reclassified or found to have overstated ESG credentials.
Asset Managers
Exposure: Marketing materials, pitchbooks, and oral communications all fall within the guidance scope. Review required.
Opportunity: Clear, substantiated ESG claims become a competitive advantage as ambiguous claims lose credibility.
Risk: Enforcement remains supervisory rather than punitive for now, but Q2 2026 greenwashing report may shift the approach.
Law Firms
Exposure: Client advisory needs increasing as ESG disclosure requirements evolve toward SFDR 2.0.
Opportunity: Fund structuring, marketing review, and compliance advisory demand accelerating.
Risk: Regulatory complexity across EU jurisdictions as NCAs implement guidelines at different paces (Bulgaria: April 2026).
Due Diligence Questions
Questions to incorporate when evaluating fund managers or portfolio company ESG claims:
ESG Integration Claims
- → Is ESG integration binding or advisory in the investment process?
- → At what stage does ESG analysis occur (screening, due diligence, portfolio construction, monitoring)?
- → Can you document instances where ESG factors led to concrete portfolio action (exclusion, reduction, exit)?
- → How does ESG integration differ from pure risk management?
ESG Exclusion Claims
- → What specific sectors, activities, or companies are excluded? Provide the complete list.
- → What revenue thresholds trigger exclusion (0%, 5%, 10%)?
- → How do exclusions compare to the Paris Aligned Benchmark (PAB) requirements?
- → What is the portfolio impact of these exclusions (percentage of universe excluded)?
Regulatory Compliance
- → Has the fund changed its name or SFDR classification since November 2024?
- → What changes, if any, are planned for SFDR 2.0 compliance?
- → Has the fund received any supervisory inquiries regarding ESG claims?
Red Label Assessment
Primary Assessment
This guidance represents a definitional tightening, not a regulatory overhaul. The immediate impact is on marketing and disclosure practices. Enforcement risk remains low in the near term, but reputational and LP-relationship risk is significant. Managers with substantiated, binding ESG processes will differentiate; those relying on vague integration claims face pressure to either substantiate or rebrand.
Alternative Interpretation
The mass renaming following the May 2025 deadline may indicate the market has already adjusted. Managers who retained ESG terminology have presumably substantiated their claims. The guidance may reinforce existing practice rather than drive new changes.
Watch For
ESMA's Q2 2026 greenwashing report will indicate whether the supervisory approach shifts toward formal enforcement. Any NCA enforcement actions in the interim would signal a harder line. SFDR 2.0 legislative progress will determine the timeline for the next structural change.
