Wondering what is greenwashing? It is when a company makes its product or practices sound more environmentally friendly than they really are. You can spot it by checking for vague words, missing proof and selective facts.
This guide sits under our broader explainer on what is sustainability, and it focuses on the marketing side.
| Item | Value |
|---|---|
| Shoppers reading an unqualified “green” or “eco-friendly” claim as “no negative environmental impact” (FTC study) | 27 percent |
| Same reading when the “green” claim was qualified | 16 percent |
| Same reading when the “eco-friendly” claim was qualified | 17 percent |
| Principles in the UK Green Claims Code | Six |
| Date the UK CMA guidance was published (per Business Companion) | 20 September 2021 |
The figures come from the US Federal Register notice of 15 October 2010 and Business Companion’s note on the UK code. Rules and guidance can change, so check the source before you rely on them.
What greenwashing looks like in practice
A true detail can be stretched into a bigger impression: one recycled component becomes “a sustainable product”.
The trouble is that shoppers fill gaps with their own assumptions. A bold word with nothing behind it invites you to assume the best.
Common forms include:
- Vague words such as “green”, “natural”, “eco” or “planet-friendly” with no explanation.
- Green imagery like leaves, earth tones and globes that suggest benefits the text never states.
- Irrelevant claims, such as boasting that a product is free of a substance that was never allowed in it anyway.
- Hidden trade-offs, where one good feature distracts from a larger harm elsewhere in the product’s life.
- Made-up labels that look like certifications but are created by the brand itself.
Why vague words mislead: what the research shows
The US Federal Trade Commission tested how people read general claims while reviewing its Green Guides. In its October 2010 notice, it reported that 27 percent of respondents took unqualified “green” and “eco-friendly” claims to mean a product had no negative environmental impact.
When the claim was qualified, fewer people drew that conclusion: 16 percent for “green” and 17 percent for “eco-friendly”. The same notice said such broad claims are so difficult to substantiate that marketers were advised against unqualified seals or certifications.
The takeaway is simple. A specific claim (“made with recycled plastic, and here is the exact share”) gives you something to check, while a broad one gives you only a feeling.
What regulators say a fair claim needs
The UK Competition and Markets Authority published its Green Claims Code on 20 September 2021, according to Business Companion. The guidance rests on six principles drawn from existing consumer law.
- Claims must be truthful and accurate.
- Claims must be clear and unambiguous.
- Claims must not omit or hide important relevant information.
- Comparisons must be fair and meaningful.
- Claims must consider the full life cycle of the product or service.
- Claims must be substantiated.
These principles also work as a checklist for you as a buyer. If a claim fails any of them, treat it with caution.
A quick checklist for spotting misleading eco claims
You do not need specialist knowledge to test a claim. Run through these questions before you buy.
- Is it specific? Look for a measurable detail, such as a percentage, a material or a named change.
- Is it about the whole product? A claim about the packaging only should say so.
- Is there proof? Look for a named third-party certification you can look up, or a published report.
- Is it a fair comparison? “Greener than before” means little without knowing the starting point.
- What is left out? Ask what the claim does not mention, such as manufacturing, transport or disposal.
Labels deserve extra care. The FTC notice treated unqualified seals and certifications as a risk because they imply broad benefits that are hard to prove.
Greenwashing beyond products: finance and fashion
Misleading claims are not limited to household goods. Investment funds can use sustainable-sounding names while holding assets that do not match, which is why it helps to understand what is ESG and how those ratings are built.
Clothing is another hot spot, with vague terms like “conscious” or “eco collection” common on labels. Our guide on what is sustainable fashion explains what real practices look like, so you can compare them with the marketing.
Examples of wording to question
Certain phrases show up again and again. None proves wrongdoing, but each should prompt a follow-up question.
| Phrase | Question to ask |
|---|---|
| “Eco-friendly” | Friendly in what way, and compared with what? |
| “Natural” | Natural does not mean harmless or low-impact. What is the actual material or process? |
| “Carbon neutral” | Is it based on cutting emissions or on offsets, and who verified it? |
| “Recyclable” | Can it be recycled where you live, or only in theory? |
| “Sustainable” | Which part is sustainable: the sourcing, the factory or the packaging? |
The phrases are common examples, and the FTC’s 2010 notice found that relatively few people linked the term “sustainable” to any particular environmental benefit; check that source before relying on it. That fits the pattern: the word feels positive but often says little.
Even a well-meant claim can slip when it is shortened for a label or an advert.
Offsets and “net zero” pledges are a special case. A pledge for a future date tells you about intent, not about what the product does today, so look for the plan and interim results behind it.
Also watch the timing of announcements. A big campaign about one small improvement can draw attention away from the larger impacts of the business.
What to do if you suspect a claim is misleading
Start by looking for the company’s evidence, which is often in a sustainability report or on a product page. If you cannot find any, that gap is informative in itself.
You can also report concerns to your national consumer or advertising regulator, which in the UK includes the CMA. This site is independent and is not connected to any regulator or company mentioned here, and it cannot take complaints.
Keep your expectations realistic as well. A company can have genuine progress and still overstate it, so the aim is to judge each claim by its evidence rather than to distrust every brand.
Frequently asked questions
What is greenwashing in simple terms?
Show answer
It is marketing that makes something look more environmentally friendly than the evidence supports. It can involve vague wording, selective facts or imagery that implies benefits.
Is greenwashing always intentional?
Show answer
No. Some firms overstate claims through carelessness or by repeating what a supplier told them. Intent matters less to you as a shopper than whether the claim can be backed up.
Are words like “eco-friendly” banned?
Show answer
The FTC’s 2010 notice advised that broad unqualified claims are hard to substantiate, and the UK code asks for clear, substantiated wording. Rules differ by country, so check your local regulator.
How can I tell if a label is a real certification?
Show answer
Look for the name of the certifying body and search for it independently. Check what the label actually covers, since many cover only one aspect of a product.
