Greenwashing is no longer a reputational risk. It is a legal and financial one — with fines now measured in millions, not warnings. The penalty landscape varies sharply by country: the EU and UK are tightening rules simultaneously, France has already handed out a €40 million fine, and the US continues active FTC enforcement while its regulatory framework remains in flux. Here is a precise, country-by-country breakdown of what your business can be fined for making unsubstantiated green claims in 2026.
Global penalty comparison at a glance
The table below summarises maximum penalty thresholds for greenwashing by jurisdiction as of February 2026. Note that most of these represent upper limits — actual penalties depend on violation severity, company size, and whether infringement was deliberate.
| Jurisdiction | Authority | Maximum Penalty | Court Required? | Effective Date |
|---|---|---|---|---|
| EU (27 states) | National NCAs under ECGT | 4% of annual EU turnover (minimum) | No (from Sept 2026) | 27 Sept 2026 |
| United Kingdom | CMA / ASA | 10% of global group turnover (CMA) | No (since April 2025) | April 2025 |
| France | DGCCRF | 10% avg. annual turnover or 80% of ad spend | Possible (criminal) | Now (Climate Law 2021) |
| Netherlands | ACM | EUR 900,000 per violation (+ reputational) | No | Now (UCPD transposition) |
| Germany | Verbraucherzentralen / courts | Variable (injunctions + damages) | Yes | Now |
| United States | FTC / SEC / State AGs | Up to $50,120 per violation (FTC); SEC unlimited | FTC: No; SEC: Yes | Now |
| Australia | ACCC / ASIC | AUD 50 million or 30% of adjusted turnover | Yes | Now |
EU: the ECGT 4% rule (effective September 2026)
The Empowering Consumers for the Green Transition Directive (Directive 2024/825) — better known as the ECGT — entered into force on March 26, 2024. EU member states must transpose it into national law by March 27, 2026, and enforcement begins on September 27, 2026.
The penalty framework in Article 24 requires member states to impose fines of at least 4% of annual turnover in the affected EU member states. Some states are expected to go higher. Beyond financial fines, enforcement tools include:
- Mandatory corrective advertising (at the company's expense)
- Public disclosure of the infringement on the regulator's website
- Confiscation of revenues and profits derived from the misleading claim period
- Temporary exclusion from public procurement for up to 12 months
The ECGT specifically bans claims like "carbon neutral", "climate positive", "eco-friendly", or "sustainable" unless backed by independently verified lifecycle assessments. Sustainability labels not based on approved third-party certification schemes are also prohibited from September 2026. For a full list of banned terms, see our EU banned green terms guide.
Companies already under investigation by any national authority before September 2026 are at elevated risk: regulators across the EU are building case files now, to be converted into formal sanctions the moment the directive is enforceable.

UK: CMA's new 10% global turnover power
The UK left the EU but created its own aggressive anti-greenwashing regime. The Digital Markets, Competition and Consumers Act 2024 (DMCCA) came into force on April 6, 2025, transforming the Competition and Markets Authority (CMA) from a watchdog that needed court orders into one that can act directly.
Since April 2025, the CMA can:
- Investigate greenwashing claims without court involvement
- Issue binding enforcement orders requiring corrective action
- Fine companies up to 10% of their global group turnover — the highest percentage threshold of any major jurisdiction
- Fine individuals up to £300,000 for deliberate personal involvement in misleading practices
The UK Advertising Standards Authority (ASA) operates in parallel, banning non-compliant advertisements and naming companies publicly. The ASA banned Ryanair's "lowest carbon airline" claim in 2020 and HSBC's climate commitment advertisements in 2022 — both cases establishing precedents now used actively in 2026 enforcement.
The CMA's Annual Plan 2025–2026 identifies misleading green claims as a priority area. Chief Executive Sarah Cardell confirmed early actions would target the most egregious cases, with broader sector sweeps to follow. Financial services firms face additional scrutiny from the Financial Conduct Authority (FCA), which requires all financial product sustainability claims to be substantiated and capable of independent verification.
France: criminal liability and the Shein case
France operates the toughest criminal framework for greenwashing among major economies. The 2021 Climate and Resilience Law (Loi Climat et Résilience) built on existing consumer protection law to create a three-tier penalty system:
- Administrative fines: up to €300,000 per violation (DGCCRF)
- Proportional penalties: up to 10% of average annual turnover, or 80% of the expenditure on the offending advertising
- Criminal sanctions: up to 2 years' imprisonment and fines under criminal code provisions for deliberate deception
The highest-profile recent case: the DGCCRF fined Shein €40 million in 2025 following a months-long investigation into the fast-fashion company's environmental claims and misleading discount practices. This is the largest single greenwashing-related fine in French enforcement history.
France's approach is notable for its willingness to pursue criminal charges — not just administrative penalties. Marketing executives and sustainability officers who personally sign off on false claims can face individual prosecution. For companies in the fashion sector specifically, see our guide on fashion industry greenwashing claims and EU rules.
Netherlands: the ACM's aggressive enforcement model
The Dutch Authority for Consumers and Markets (ACM) has been one of the most proactive greenwashing regulators in Europe. Its enforcement model is instructive: rather than imposing fines after lengthy legal proceedings, the ACM typically requires companies to make substantial donations to environmental causes as undertakings, combined with mandatory removal of misleading claims and public disclosure of findings.
Key enforcement outcomes include:
- H&M: Required to remove "Conscious Collection" labeling and revise sustainability communications across Dutch markets (2022–2023)
- Decathlon: EUR 400,000 donation to sustainable causes for unsubstantiated environmental product claims (2022)
- Vattenfall & Greenchoice: EUR 950,000 and EUR 450,000 donations respectively for unclear sustainability claims (2022)
- KLM: Amsterdam District Court ruled KLM's "sustainable flying" claims were misleading and unlawful (2024)
The ACM's 2025 annual plan prioritises the food and beverage sector, building on existing enforcement infrastructure. From September 2026, the ACM gains additional authority under the ECGT transposition.
Germany: private enforcement and Verbraucherschutz
Germany's enforcement model differs structurally from most EU countries. Rather than relying primarily on a central regulatory authority, Germany uses a system of private enforcement through Verbraucherzentralen (consumer protection organisations) and industry associations (Wettbewerbszentrale), which can file injunctions against misleading green claims in commercial courts.
German consumer protection bodies launched over 40 formal warning letters and injunction proceedings against companies using unsubstantiated environmental claims in 2024 alone. The courts have been receptive: German judges have consistently upheld that vague terms like "climate neutral" or "CO2-compensated" without transparent methodology disclosure are unfair commercial practices under the Gesetz gegen den unlauteren Wettbewerb (UWG).
Under ECGT transposition (due by March 27, 2026), Germany will add administrative fining authority to its existing court-based system, creating a dual enforcement track that significantly increases overall risk exposure for companies operating in the German market.
United States: FTC fines and the Green Guides
The US Federal Trade Commission (FTC) enforces environmental marketing claims under Section 5 of the FTC Act (prohibition on unfair or deceptive practices) and its Green Guides, last formally updated in 2012. Unlike European authorities, the FTC cannot issue fines directly in first-instance cases — it must first obtain a consent order, after which violations carry penalties of up to $50,120 per violation per day.
Notable enforcement outcomes with specific dollar amounts:
- Walmart: $3 million civil penalty for marketing rayon textile products as made from bamboo (FTC and DOJ action)
- Kohl's: Part of the same $5.5 million combined settlement for bamboo/rayon labeling — the largest-ever civil penalty for misleading product environmental claims at that time
- LED manufacturers: $21 million in FTC-ordered penalties for exaggerated energy efficiency claims
- Keurig Dr Pepper: $1.5 million SEC fine for inaccurate recyclability claims (2024)
The Green Guides were expected to be updated in 2024 to address carbon offsets, climate neutral claims, and recyclability standards. Those updates remain pending as of February 2026, creating regulatory uncertainty. However, individual state attorneys general — particularly in California, New York, and Massachusetts — have been increasingly aggressive, filing state-level actions that do not depend on FTC Green Guides updates.
The SEC separately enforces ESG disclosures under securities law, with unlimited financial penalty authority for publicly traded companies that make material misstatements in sustainability reports or investor communications. For companies in the financial sector, see our guide on ESG fund greenwashing and finance sector risks.
Australia: ACCC and ASIC joint enforcement
Australia has emerged as an unexpected frontrunner in greenwashing enforcement. The Australian Competition and Consumer Commission (ACCC) and the Australian Securities and Investments Commission (ASIC) operate coordinated enforcement campaigns.
Under the Australian Consumer Law, courts can impose penalties of:
- AUD 50 million per violation
- Or 3 times the benefit obtained from the conduct
- Or 30% of adjusted turnover during the period of the conduct
- Whichever is greatest
In June 2025, the ACCC commenced Federal Court proceedings against Australian Gas Networks, alleging its claim that gas distributed on its network would become renewable "within a generation" was false and misleading — specifically because the company had no credible plan to achieve this. ASIC has identified greenwashing as a priority in its 2025 enforcement strategy, with particular focus on superannuation funds and managed investment schemes that market themselves as sustainable or responsible.
What actually triggers a greenwashing investigation
Regulatory investigations in 2025–2026 have consistently been triggered by a narrow set of patterns. Understanding these allows businesses to prioritise remediation efforts before September 2026.
The highest-risk behaviours are:
- Carbon neutral or climate neutral claims based on offsets: Every major jurisdiction has moved against this. Offset-based neutrality claims are effectively banned under ECGT, challenged by the FTC, and have been the basis of court rulings in Australia and the Netherlands. See our dedicated analysis of carbon neutral claim bans in the EU.
- Generic "eco" or "green" terms without substantiation: The ECGT explicitly bans generic environmental claims. Regulators in Germany, the Netherlands, and the UK have all issued findings against companies using "eco-friendly", "sustainable", "responsible", or "green" without lifecycle assessment evidence.
- Comparative claims without methodology disclosure: The Ryanair case established this clearly: even a technically accurate comparative claim becomes misleading if consumers cannot understand the basis for the comparison.
- Omission of material negative information: The HSBC case in the UK defined this category. Highlighting positive environmental initiatives while omitting a company's overall carbon footprint or continued fossil fuel investment constitutes a misleading omission.
- Sustainability labels not based on approved schemes: Self-created eco-labels are prohibited under ECGT from September 2026. Any label not derived from an EU Ecolabel, Energy Star, or equivalent third-party certified scheme will face enforcement.

How to protect your business before September 2026
The convergence of ECGT (September 2026), the UK DMCCA (already in force), and active enforcement in France, the Netherlands, and Australia means the window for voluntary remediation is narrowing. Companies that act now can correct claims without penalty; companies that wait will face enforcement in a regime where regulators have invested resources building cases.
The essential steps are:
- Audit all environmental claims across all channels: website copy, product packaging, social media, press releases, and annual reports. Cross-channel inconsistency is itself a red flag.
- Document substantiation for every surviving claim: lifecycle assessment reports, third-party certification certificates, specific data sources. If you cannot produce the evidence immediately, withdraw the claim immediately.
- Remove or rephrase generic terms: replace "eco-friendly" with specific, quantified statements. Replace "sustainable" with what is actually being measured and certified.
- Eliminate offset-based neutrality claims: reframe around verified reduction milestones rather than neutrality achieved through offsetting.
- Implement approval governance: every new environmental claim must pass through a legal or compliance review before publication.
