7 Types of Greenwashing: How Companies Make False Green Claims
7 Types of Greenwashing: How Companies Make False Green Claims
Last updated: 24 June 2026 | Author: VerdaScope Editorial Team
Greenwashing examples are everywhere in UK marketing—from “eco” fashion edits to “green” energy tariffs and “sustainable” fund names. Not every environmental claim is deceptive, but regulators repeatedly see the same patterns: vague language, missing evidence, and imagery that promises more than the product delivers. This guide explains the seven types of greenwashing (the TerraChoice “seven sins” framework), maps each to examples of greenwashing from real greenwashing companies, and shows what UK businesses can learn for compliant greenwashing in marketing.
For the core definition and pillar overview, start with what is greenwashing. For legal requirements, see the CMA Green Claims Code.
Direct Answer
The seven sins of greenwashing describe seven recurring ways firms make false environmental claims: hidden trade-off, no proof, vagueness, false labels, irrelevance, lesser of two evils, and outright fibbing. UK regulators do not use this list as law—but the patterns align closely with the CMA Green Claims Code principles (truthful, clear, complete, fair comparison, life-cycle consideration, and substantiation). Recognising the sin type helps compliance teams fix claims before the CMA or ASA does.
Key Takeaways
- The TerraChoice framework names seven types of misleading green marketing—still widely used because patterns repeat across sectors.
- Hidden trade-off greenwashing highlights one benefit (recycled packaging) while ignoring larger impacts (production, transport, disposal).
- UK enforcement increasingly targets vague collection branding—“responsible,” “eco,” or “for good” ranges without published criteria.
- False labels and self-made eco-badges are high risk unless backed by independent, objective standards.
- The CMA’s six Green Claims Code principles are the practical compliance test for any example on this list.
- Use the summary table and FAQ to train marketing, product, and legal teams on greenwashing in marketing.
The Seven Sins Framework: Where It Came From
TerraChoice (later part of UL Solutions) published research on misleading environmental claims in consumer products, identifying six sins in 2007 and expanding to seven sins in subsequent reports. The framework was based on scanning consumer products in North American retail—not UK law—but it remains one of the most cited greenwashing examples taxonomies worldwide.
UK enforcers use different language (misleading actions and omissions under the CPRs), but the sins still help teams classify weak claims quickly.
| Sin | Core idea | CMA principle most aligned |
|---|---|---|
| Hidden trade-off | One green attribute masks bigger harms | Life cycle; omissions |
| No proof | Claim without evidence | Substantiation |
| Vagueness | Broad, undefined terms | Clear and unambiguous |
| False labels | Misleading certifications or icons | Truthful and accurate |
| Irrelevance | Trivial or legally mandated “benefit” | Truthful and accurate |
| Lesser of two evils | “Greener” within a harmful category | Fair comparison; life cycle |
| Fibbing | Factually false claims | Truthful and accurate |
1. Sin of the Hidden Trade-Off
Hidden trade-off greenwashing promotes a single environmental benefit while downplaying—or omitting—significant negative impacts elsewhere in the product life cycle.
How it appears in marketing
- “Recycled packaging” on a product with high-carbon manufacturing or non-recyclable multi-material construction
- “Locally assembled” when components are shipped globally
- “Reduced plastic” label when overall environmental impact increased due to heavier glass or longer transport routes
UK-relevant example pattern
The CMA’s Green Claims Code includes a case-style example of a yoghurt pot marketed with “reduced plastic packaging” and green leaf imagery when the plastic reduction is only 5%—offset by moving production to a more distant facility, with little or no net benefit. That is a classic hidden trade-off: a narrow truth used to imply broader improvement.
Fashion sector parallel
In its 2022 fashion investigation, the CMA questioned whether recycled-fabric percentages in “green” collections told the whole story when range branding implied broader sustainability. See greenwashing in fashion.
How to avoid it
- Assess full life cycle impacts—or narrow the claim to the specific stage you can evidence (e.g. “packaging made from 60% recycled cardboard”).
- Disclose trade-offs where consumers need them to decide.
2. Sin of No Proof
Claims are made with no supporting evidence, no accessible methodology, or documentation that would not withstand scrutiny.
How it appears
- “Environmentally friendly” without tests, standards, or benchmarks
- “Low carbon” without scope, boundary, or calculation method
- Website badges with no link to criteria
UK regulatory view
The CMA’s substantiation principle requires businesses to hold robust, credible evidence for claims before they are made—not assembled after a complaint. The ASA applies similar expectations through the CAP Code.
Example pattern from sector reviews
The European Commission’s research (cited in EU green claims policy materials) found a large share of voluntary green claims lacked supporting evidence. UK CMA sector work has similarly highlighted claims that could not be verified from the information shown to consumers.
How to avoid it
Build a substantiation file for each claim: data source, date, scope, approver, and review schedule. If evidence is incomplete, narrow or pause the claim.
3. Sin of Vagueness
Vagueness is among the most common greenwashing examples in UK retail. Terms like “eco,” “green,” “sustainable,” “responsible,” and “natural” suggest positive overall impact without telling consumers what was actually achieved.
Why regulators focus here
The CMA states that broad terms are more likely to mislead unless the business can prove the product, service, or business as a whole has a positive environmental impact—or at least no adverse impact. Qualifiers like “greener” still require clarity about what is being compared and how.
UK enforcement example: fashion collections
The CMA’s July 2022 investigation into ASOS, Boohoo, and George at Asda cited concerns that collection names and language—such as “Responsible edit,” “Ready for the Future,” and “George for Good”—could be too broad and vague, creating impressions that ranges were more sustainable than they were.
The March 2024 undertakings require plain-language fabric statements, defined collection criteria, and restrictions on ambiguous terms without further explanation.
How to avoid it
Replace vague terms with specific, measurable claims:
| Risky | Clearer |
|---|---|
| “Sustainable collection” | “Collection: each garment contains minimum 50% recycled fibres (see label)” |
| “Eco-friendly cleaning” | “Biodegradable formula per [defined standard]; bottle 100% recycled HDPE” |
| “Green energy” | “Tariff backed by REGO certificates for 100% renewable electricity supply” |
4. Sin of Worshipping False Labels
This sin covers misleading use of labels, logos, and certification marks—including fake third-party badges, self-created “eco” symbols, and accreditation marks applied more broadly than their scope allows.
How it appears
- A green leaf icon implying third-party certification when none exists
- “Certified sustainable” when certification applies only to one facility, not the product
- Trust marks without a link to standards or verification body
CMA guidance
The Green Claims Code warns that self-assessed marks are more likely to raise concerns than labels based on clear, publicly available criteria and independent assessment. Claims should explain what a symbol means and how consumers can verify it.
UK example pattern
The CMA’s fashion investigation included concerns about statements on fabric accreditation schemes where it was unclear whether accreditation applied to particular products or wider corporate practices.
How to avoid it
- Use only marks you are contractually entitled to display, at the correct product/firm scope.
- Explain the scheme on-pack or one click away.
- Never design icons that mimic official ecolabels.
5. Sin of Irrelevance
Irrelevance means trumpeting an environmental “benefit” that is legally required, industry-standard, or too trivial to influence real impact—while implying exceptional performance.
CMA example
The Green Claims Code cites rinse-off cosmetics advertised as “microbead free” when microbeads are already banned in such products in the UK. The statement may be true but misleads consumers into thinking the product is superior to others.
Other patterns
- “CFC-free” on aerosols years after CFC phase-out
- “Complies with environmental law” presented as a differentiator
- Highlighting a 1% recycled content increase on an otherwise high-impact product
How to avoid it
Ask: Is this claim distinguishing our product, or stating the baseline? If baseline, do not market it as a benefit.
6. Sin of the Lesser of Two Evils
This sin frames a product in a harmful category as environmentally preferable without addressing the category’s fundamental impact—or suggests “green” status relative only to a poor comparator.
How it appears
- Marketing disposable single-use items as “greener” without addressing disposability
- Fast fashion marketed as “sustainable” based on partial recycled content while production volume and landfill impacts remain high
- High-emitting vehicles promoted as “more efficient” only within an inefficient class
UK fashion context
Fashion’s environmental challenges include volume, synthetic fibres, dyeing, and short garment life. A recycled polyester dress may be less bad than a virgin polyester dress, but marketing it as “sustainable fashion” without context can still mislead—particularly when consumers interpret labels as addressing the whole impact of the category.
How to avoid it
- Use fair comparisons with clear baselines.
- Avoid implying category-level virtue from attribute-level improvements.
- Pair marketing with durability, repair, or take-back programmes where relevant—without overstating their effect.
7. Sin of Fibbing
The most straightforward sin: claims that are demonstrably false—fabricated percentages, non-existent certifications, or emissions data that does not match reality.
How it appears
- Incorrect recycled content figures
- False “organic” composition
- Claiming carbon neutrality with no offsets or reductions in place
UK consequences
False claims are the clearest path to enforcement. The CPRs prohibit misleading actions; demonstrably false statements are unlikely to survive regulatory or ASA review.
How to avoid it
- Verify supplier certificates and lab tests.
- Separate marketing drafts from verified data sources.
- Escalate any claim where evidence is uncertain.
Summary Table: Seven Types at a Glance
| # | Sin | Typical consumer impression | Fix |
|---|---|---|---|
| 1 | Hidden trade-off | “This product is green overall” | Disclose scope; life-cycle thinking |
| 2 | No proof | “This is verified” | Substantiation files; public methodology |
| 3 | Vagueness | “Sustainable means something good” | Specific metrics and plain language |
| 4 | False labels | “An expert certified this” | Legitimate marks only; explain scope |
| 5 | Irrelevance | “This is special” | Do not claim mandated baselines |
| 6 | Lesser of two evils | “Good for the planet” | Honest comparison; category context |
| 7 | Fibbing | “Data backs this” | Verification and audit trails |
Greenwashing Companies: What UK Cases Teach Marketers
Studying greenwashing companies is not about naming and shaming—it is about recognising patterns regulators already target.
| Organisation / sector | Allegation pattern (regulatory concern) | Outcome / status (as of June 2026) |
|---|---|---|
| ASOS, Boohoo, George at Asda | Vague eco-range branding; low criteria thresholds; misleading filters and imagery | CMA undertakings, March 2024 (no admission of wrongdoing) |
| Fashion sector (wider) | Broad “sustainable” presentation with limited supporting information | CMA open letter and sector guidance |
| H&M (Norwegian Consumer Authority) | Environmental labelling on Conscious Collection lacked adequate substantiation for consumers | Authority statement, 2021—illustrates EU/Nordic scrutiny of fashion labels |
| Various energy retailers (ASA) | “Green” and “renewable” tariff claims lacking clarity | Multiple ASA rulings—claims amended or banned |
Enforcement status changes. Check primary sources before citing outcomes in external materials.
Using the Framework in Compliance Reviews
Marketing brief checklist
When reviewing a campaign, tag each environmental statement with a sin type:
- Does it highlight one attribute only? → Hidden trade-off risk
- Is evidence attached? → No proof risk
- Is language broad? → Vagueness risk
- Any icons or badges? → False labels risk
- Is the benefit legally required? → Irrelevance risk
- Is the product category inherently high-impact? → Lesser of two evils risk
- Are numbers verified? → Fibbing risk
If any risk is high, cross-check against the CMA Green Claims Code and escalate to legal or sustainability leads.
Frequently Asked Questions
What are the main greenwashing examples?
Common examples include vague “eco” labels, unqualified recyclability claims, misleading green imagery, false certification marks, offset-only carbon claims, and “sustainable” product ranges without published criteria.
What are the seven sins of greenwashing?
They are: hidden trade-off, no proof, vagueness, false labels, irrelevance, lesser of two evils, and fibbing. TerraChoice popularised the list in research on consumer product claims.
What is hidden trade-off greenwashing?
It is when marketing emphasises one environmentally positive attribute while ignoring more significant negative impacts elsewhere—such as promoting recyclable packaging while omitting high-carbon production.
Which greenwashing companies have UK regulators investigated?
The CMA investigated ASOS, Boohoo, and George at Asda over fashion green claims, securing undertakings in March 2024. The ASA has ruled on many firms’ environmental advertising. See what is greenwashing for context.
How does greenwashing in marketing differ from false advertising?
Greenwashing is a subset of misleading marketing focused on environmental claims. In the UK, such claims are assessed under the CPRs and CAP/BCAP Codes, guided by the CMA Green Claims Code.
How do I fix vague sustainability claims?
Replace broad terms with specific, evidenced statements—material percentages, defined standards, scope boundaries, and prominent caveats. See making legitimate green marketing claims.

Training Exercise: Classify These Claims
Use the seven sins to classify each statement. Answers follow.
- “Our hotel is eco-certified” (hotel developed its own leaf badge with no third-party standard)
- “Now with 10% more recycled plastic” (product still 90% virgin plastic; ad implies major improvement)
- “CFC-free aerosol” (CFCs banned decades ago in this product class)
- “Carbon-neutral flights” (offsets only; no airline efficiency data shown)
- “Organic skincare” (3% organic ingredients)
Likely classifications: (1) false labels; (2) hidden trade-off or vagueness; (3) irrelevance; (4) vagueness and possible omissions on offsets; (5) fibbing or vagueness depending on ingredient prominence.
