What Legal Risks Do Companies Face for Greenwashing?

The legal landscape for greenwashing has transformed over the period from 2020 to 2025. What was previously a primarily reputational risk — companies faced negative press for overstated environmental claims but limited legal liability — has become a multidimensional legal exposure encompassing securities enforcement, consumer protection litigation, class action lawsuits, and emerging tort theories based on misleading climate disclosures. The DWS settlement, SEC enforcement against Goldman Sachs and BNY Mellon, Delta Airlines' class action, and regulatory actions in the EU and UK have collectively created a litigation and enforcement environment where ESG misrepresentation carries material financial and legal risk. Understanding this risk landscape is essential both for companies making ESG claims and for investors assessing the legal exposure of portfolio companies.

Quick definition: Greenwashing legal liability refers to the exposure of companies, investment managers, and individuals to regulatory sanctions, civil litigation, and criminal prosecution arising from misleading environmental, social, or governance claims — including securities fraud liability for misleading ESG disclosures to investors, consumer protection liability for misleading product environmental claims, and potential tort liability for misleading climate commitments.

Key takeaways

• Securities fraud is the primary legal theory for investment greenwashing liability: materially misleading ESG claims in regulated disclosures (fund prospectuses, Form ADV, annual reports) violate the Investment Advisers Act, the Investment Company Act, or Exchange Act Rule 10b-5.
• Consumer protection liability applies to product greenwashing: the FTC Green Guides, UK Green Claims Code, and EU Green Claims Directive (proposed) provide the basis for regulatory action and private litigation against unsubstantiated product environmental claims.
• Private litigation for greenwashing is growing: class action lawsuits targeting misleading ESG fund marketing (Delta Airlines carbon neutrality claim), securities fraud class actions against companies with misleading climate disclosures, and consumer protection class actions against product greenwashing have all occurred in the 2022-2025 period.
• EU regulatory framework creates additional liability pathways: SFDR misclassification, CSRD disclosure inaccuracies subject to assurance requirements, and EU Taxonomy misrepresentation create regulatory and civil liability beyond US securities law.
• Directors and officers face increasing personal accountability: in several enforcement actions and investigations (DWS CEO resignation, individual criminal charges in the Volkswagen case), individual accountability for greenwashing has reached beyond corporate-level sanctions.

Securities Fraud Liability

The Legal Framework

Securities fraud liability for ESG greenwashing typically relies on three legal theories:

Section 10(b) and Rule 10b-5 (Exchange Act): It is unlawful to make any untrue statement of material fact in connection with the purchase or sale of securities, or to omit a material fact necessary to prevent other statements from being misleading. This is the principal federal securities fraud provision — it applies to public company disclosures, fund marketing materials, and statements made to investors.

Investment Advisers Act Section 206: Investment advisers are prohibited from engaging in fraudulent, deceptive, or manipulative conduct. SEC enforcement actions against BNY Mellon and Goldman Sachs relied on Section 206(2) (prohibited conduct harmful to clients) and Section 206(4) (prohibited conduct with clients using mail or interstate commerce), with implementing Rule 206(4)-8 (prohibiting false statements to investors in pooled investment vehicles).

Investment Company Act Section 34(b): Prohibits registered investment companies from making any untrue statement of material fact in required documents (including registration statements and annual reports).

Materiality: For securities fraud liability, the misrepresentation must be material — a reasonable investor would consider it important in making an investment decision. ESG credentials are material to investors who specifically seek ESG funds; misrepresentation of ESG process or credential is therefore material for ESG-labeled products marketed to ESG-seeking investors.

Enforcement Actions

The primary securities fraud enforcement actions for ESG greenwashing through 2025:

Case	Regulator	Amount	Year	Key Theory
BNY Mellon	SEC	$1.5 million	2022	False statements that all positions had undergone ESG review
Goldman Sachs	SEC	$4 million	2023	Policy/procedure failures leading to ESG policy non-compliance
DWS (US)	SEC	$19 million	2023	Overstated ESG AUM integration claims
DWS (Germany)	BaFin	~€6.5 million	2023	ESG misrepresentation in German operations
HSBC Asset Management	FCA	£6.28 million	2023	Misleading climate marketing for bond funds

Private Securities Litigation

Beyond regulatory enforcement, private securities fraud litigation by investors has emerged:

Securities fraud class actions: Shareholders of companies that have made materially misleading ESG claims have filed class action lawsuits alleging that stock price declines following ESG disclosure restatements or greenwashing revelations constitute securities fraud. These cases typically allege that company management made material misstatements about ESG credentials, that investors relied on those statements, and that subsequent disclosure of ESG claim inaccuracies caused stock price decline.

ESG fund investor claims: Investors in ESG-labeled funds who allege that the fund did not invest as described have filed suits against fund managers for breach of fiduciary duty and securities fraud. These cases face challenges around materiality (is the ESG methodology important enough to the investment decision to be material?) and damages (did the misrepresentation cause financial harm beyond values harm?).

Consumer Protection Liability

FTC Enforcement

The FTC's Green Guides create a substantiation standard for consumer product environmental claims. FTC enforcement actions can result in:

• Injunctions requiring cessation of false claims
• Civil penalties for knowing violations (up to $50,000 per violation per day under FTC Act Section 5)
• Consumer restitution in appropriate cases
• Consent orders requiring corrective advertising

Private Consumer Litigation

Consumer class action lawsuits targeting product greenwashing have grown substantially:

State consumer protection laws: California's Unfair Competition Law (UCL), Consumers Legal Remedies Act (CLRA), and False Advertising Law (FAL) are particularly favored for greenwashing class actions because of their broad standing requirements (consumer victims can sue without proving individual injury in some contexts) and attorneys' fees provisions.

Delta Airlines carbon neutrality class action (2023): Filed in California under the UCL and CLRA, the Delta class action alleged that Delta's "carbon neutral airline" marketing was misleading because the offset credits underlying the claim did not represent genuine emissions reductions. The case is a test of whether offset-based carbon neutrality claims create consumer protection liability when the offset quality is insufficient.

Fashion brand greenwashing: Multiple class actions have been filed against fashion brands for "sustainable" collection marketing, "recycled material" content claims, and sustainable sourcing certifications where the underlying supply chain practices did not meet implied standards.

EU Consumer Protection Framework

The EU Unfair Commercial Practices Directive prohibits misleading commercial practices, including misleading environmental claims. The proposed Green Claims Directive would add:

• Substantiation requirement for all environmental claims
• Pre-market independent verification for explicit claims
• Prohibition on unsubstantiated generic environmental terms

Emerging Liability Theories

Climate Liability for Misleading Commitments

Litigation theory is developing around whether companies that make public net-zero or climate commitment pledges and fail to follow through face legal liability beyond consumer protection:

Common law fraud: If a company makes a materially false representation (a net-zero pledge) knowing it is false, and investors or others rely on it to their detriment, common law fraud may apply.

Statutory securities fraud: If a net-zero pledge is materially misleading to investors and causes stock price inflation, subsequent correction may cause a claim under Rule 10b-5. Several securities class actions against companies for climate pledge misrepresentation have been filed, though success rates vary.

First Amendment defenses: Companies facing litigation for misleading climate claims have invoked First Amendment protections for puffery and opinion — courts have generally allowed securities fraud claims to proceed where the claims involve specific factual representations (e.g., "we are on track to meet our 2030 emissions target") but have been more protective of general aspirational statements.

Criminal Liability

The Volkswagen Dieselgate criminal prosecutions established that deliberate corporate environmental fraud can generate individual criminal liability:

• VW AG paid $2.8 billion in criminal fines (corporate criminal liability)
• Multiple VW executives were individually charged; some received prison sentences in German courts
• Former VW CEO Winterkorn was indicted by US federal prosecutors (though not extradited for trial)

For investment greenwashing, the DWS BaFin criminal referral (resolved without criminal conviction) showed that regulators in some jurisdictions treat serious ESG misrepresentation as potentially criminal rather than merely civil.

Risk Management for Companies

Companies managing greenwashing legal risk should focus on:

Claim substantiation before publication: All environmental and social claims in both marketing materials and investor communications should be reviewed for substantiation — can the company provide the "competent and reliable scientific evidence" or documented investment process basis that regulators require?

Consistency across disclosure contexts: The same company cannot claim different ESG credentials in marketing, investor presentations, and regulatory filings. Inconsistency between contexts is a greenwashing red flag that regulators specifically look for.

Documentation of ESG processes: If ESG processes are claimed (ESG analysis on all fund holdings; ethical sourcing from all Tier 1 suppliers), the processes should be documented in operations manuals, compliance policies, and audit trails that could be produced to regulators.

Claims review by compliance and legal: ESG claims in marketing materials should be reviewed by compliance and legal counsel with specific ESG expertise, not just general marketing review.

Ongoing monitoring: ESG claims that were accurate when made can become inaccurate as business practices change, methodologies are revised, or new information emerges. Ongoing monitoring of ESG claim accuracy — with prompt correction when claims become inaccurate — reduces legal liability compared to allowing stale claims to persist.

Real-world examples

H&M investor lawsuit: H&M faced a shareholder lawsuit in Sweden alleging that misleading sustainability claims inflated H&M's stock price by suggesting a successful transition to sustainable fashion when actual sustainability performance lagged. The case demonstrates cross-pollination between consumer and investor greenwashing — the same marketing claims that generated consumer protection scrutiny also generated investor fraud allegations.

Corporate securities class actions: Several US securities class actions against public companies for misleading climate and ESG disclosures have been filed since 2021. Success rates are variable; courts have generally required specific factual misrepresentations rather than general aspirational language to sustain claims.

Common mistakes

Treating ESG claims in marketing as categorically different from securities disclosures: Marketing materials for investment funds are regulatory documents subject to anti-fraud standards — not just promotional materials. Fund factsheets, pitch decks, and website materials for regulated investment products create the same legal obligation as formal regulatory filings for material accuracy.

Assuming "carbon neutral" claims are protected opinion or puffery: Courts have generally allowed claims that specific factual representations (e.g., "our fund holds no fossil fuel companies" or "our emissions are verified by a third party") are actionable if false, while being more protective of general environmental aspirational language. Companies should be specific about what they can verify and avoid overstating specifics.

Neglecting the D&O dimension: Directors and officers who approve misleading ESG disclosures may face personal liability for securities fraud. D&O insurance covers some but not all ESG liability scenarios, and coverage is subject to exclusions for intentional fraud.

FAQ

Can individual investors sue investment funds for greenwashing?

Individual retail investors can bring consumer fraud claims or, in some circumstances, securities fraud class actions against fund managers for misleading ESG claims. The practical challenge is that retail investors typically join class actions rather than filing individual suits. Institutional investors may have grounds for direct claims depending on their relationship with the fund manager. State consumer protection laws (particularly California) have been used for individual and class action claims against consumer-facing financial products with misleading ESG marketing.

What is the statute of limitations for securities fraud greenwashing claims?

Under the Private Securities Litigation Reform Act (PSLRA), private securities fraud claims must be filed within two years of discovery of the alleged misstatement (or facts that a reasonable investor would have investigated further) and no more than five years after the violation. For regulatory enforcement, the SEC's statute of limitations for civil fraud is five years, and for disgorgement is ten years. Companies involved in ongoing greenwashing face potential liability for recent misstatements even if earlier statements are time-barred.

Summary

Greenwashing legal liability has expanded from primarily reputational risk to a multidimensional exposure encompassing SEC securities fraud enforcement (BNY Mellon, Goldman Sachs, DWS), FCA consumer protection enforcement (HSBC), private consumer class action litigation (Delta carbon neutrality), and emerging securities fraud class actions against companies with misleading climate disclosures. The legal framework relies on securities fraud (material misstatement in investor disclosures), consumer protection (unsubstantiated product claims), and emerging tort theories for misleading climate commitments. Companies can manage legal risk through claim substantiation before publication, consistency across disclosure contexts, documented ESG processes, compliance review of ESG claims, and ongoing monitoring of claim accuracy. Director and officer personal liability for approved ESG disclosures represents the accountability frontier that has most significantly altered how boards engage with ESG claim oversight.
