Avoiding Greenwashing in Retail Claims

Customers increasingly want to buy things that are better for the planet, and retailers want to show that they are. That creates a temptation to describe products in generous green language: eco, natural, sustainable, planet-friendly, responsibly made. Some of it is deserved. Much of it is vague, unprovable or simply wrong.

Greenwashing, the practice of presenting something as more environmentally friendly than it is, harms customers, honest competitors and the brand that does it. In the UK, it also carries legal risk. This guide explains the main principles for making environmental claims honestly, with a premium retailer in mind. It is not legal advice, and you should check official guidance and take advice where claims matter.

The rules in outline

GOV.UK's publication on the Green Claims Code, from the Competition and Markets Authority, says that the code helps businesses understand and meet their existing obligations under consumer protection law when making environmental claims. It sets out principles, explains the legal basis of each, gives examples and includes case studies. It also makes clear that businesses remain responsible for complying with the law, and that the guidance is not legal advice.

Separately, GOV.UK's guidance on advertising regulations describes rules against false or deceptive messages and against omitting important information, and notes that breaches can lead to enforcement, fines or prosecution. Environmental claims fall squarely within these rules.

The practical message is that every environmental claim you make must be truthful, accurate, clear and capable of being backed up.

What makes a claim misleading

A claim can mislead in several ways.

It is false. The product does not have the property claimed.

It is vague. "Eco-friendly", "green" and "kind to the planet" suggest broad benefits without saying what they are. Customers read them as promising more than is delivered.

It overstates. A small improvement is presented as a transformation.

It omits. A true claim hides a larger problem. A bag made partly from recycled material is called "sustainable", while the rest of the product has a heavy impact.

It is unsupported. There is no evidence.

It is irrelevant. A claim that something is free from a substance that is banned anyway, presented as a special virtue.

It trades on imagery. Leaves, globes and earth tones imply environmental credentials without a claim to check.

It relies on a made-up label. An invented "eco" badge that looks like a certification.

Principles for honest claims

Drawing on the spirit of the official guidance, a few principles help.

1. Be truthful and accurate

Do not say anything that is not true. Check each claim against facts, not hopes.

2. Be clear and unambiguous

Say what you mean in plain words. "Made from 80 per cent recycled polyester" is clear. "Eco fabric" is not. Think about how an ordinary customer will read it.

3. Do not omit or hide important information

If a product has a significant downside that customers would care about, do not make a headline claim that ignores it.

4. Be fair in comparisons

If you say a product is better than another, compare like with like, and say what you are comparing. "Uses less water than our previous version" is fine if true and measurable. "Better for the planet than the competition" needs evidence and care.

5. Consider the whole life of the product

A claim about one stage, such as the material, may mislead if other stages, such as manufacturing or disposal, are worse. Make clear what the claim covers.

6. Back it up

Hold evidence for every claim. It should be robust, credible and up to date. Evidence might include test results, supplier documentation, certificates from recognised bodies and calculations with stated methods.

7. Keep it current

Claims can become untrue. A supplier changes, a material is replaced, a certification lapses. Review claims regularly.

Words to handle with care

Some words and phrases are especially risky.

• "Eco-friendly", "green", "sustainable", "planet-friendly". Too broad unless carefully defined.
• "Natural". Not the same as better for the environment, and often not clearly defined.
• "Biodegradable" and "compostable". True only in particular conditions, which may not be available to customers. State them.
• "Recyclable". Only if it can actually be recycled where customers live. Say how.
• "Carbon neutral" and "net zero". Require careful, evidence-based substantiation, and should be explained.
• "Plastic-free". Only if the whole product and packaging contain none.
• "Ethical" and "responsible". Say what you mean and how you know.
• "Handmade" and "local". Define them and be able to support them.

Where you use such words, add specifics immediately: what, how much, under what conditions and how it was checked.

Make specific claims

The best way to avoid greenwashing is to be specific.

• Instead of "sustainable packaging", say "Outer carton made from recycled card; recyclable in household collections. Inner box is uncoated paper; tissue is acid-free and recyclable. We do not use plastic tape."
• Instead of "ethical wool", say "Wool from farms that hold [named certification], spun in [named mill]."
• Instead of "kinder to the planet", say "This bag uses leather from a tannery that treats and reuses its water, certified by [named body]."

Specific claims are easier to verify and harder to mislead with.

Use certifications honestly

Certifications and labels from recognised third parties add credibility, but they have rules.

• Use them only if you hold them, and for the products and scope covered.
• Follow the issuer's rules on how to display them.
• Say what they mean, in a few words.
• Do not create your own look-alike badges that imply independent verification.
• Keep certificates current and records on file.

Be careful with imagery and design

Green leaves, earth tones, paper textures and globe icons can imply environmental benefits without any claim. If your products do not have such benefits, the imagery may mislead. Use design that fits the brand without implying more than the facts support.

Do not claim what the law already requires

Presenting legal compliance as a special virtue can mislead. If a substance is banned and you do not use it, saying "free from" it as a selling point may suggest a distinction that does not exist. Be sure that a claim distinguishes you in a way that is real.

Handle offsetting and future promises carefully

Claims based on offsetting, or on future targets, need extra care. If you say a product is "carbon neutral" because of offsets, be clear about what is offset, how and by whom, and how reductions are being made. If you promise future change, such as "net zero by a certain year", explain the plan and the progress. Avoid presenting aspirations as accomplishments.

Create a claims process

A little structure protects you.

1. List every environmental claim on your site, packaging, emails, social posts and sales material.
2. For each, record the evidence: document, date, source and who checked it.
3. Rate the risk: vague or broad claims are high risk.
4. Rewrite or remove anything that cannot be supported.
5. Assign an owner for each claim.
6. Review quarterly, and whenever something changes.
7. Train staff who write copy or answer questions.
8. Take advice for significant or high-risk claims.

Keep the record, so that you can show your reasoning if challenged.

Talk about progress honestly

You do not have to claim perfection. Customers respect honesty about a journey.

• "We are reducing the plastic in our packaging. This year we removed it from the outer layer; the inner wrap is still plastic and we are testing alternatives."
• "We do not yet know the full supply chain for our linings. We have asked our suppliers and will share what we learn."

Honest incremental claims build more trust than sweeping ones, and they are safer.

Remember the reader

Google's guidance on helpful content emphasises trustworthiness, honest sourcing and clarity about who is behind a page. A page that makes careful, evidenced environmental statements fits that approach and serves customers who want to make informed choices.

A worked example

A UK homeware brand describes its candles as "eco-friendly and sustainable" in headings and packaging. The founder reads the official guidance and audits her claims.

She finds that the wax is a plant-based blend, the jars are recycled glass that can be reused, the wicks are cotton, and the outer box is recycled card. She cannot document the sourcing of the fragrance oils and uses a small plastic seal. She rewrites: "Plant-based wax blend, cotton wick, reusable recycled-glass jar. Outer box is recycled card and can be recycled with household paper. Fragrance oils are synthetic; we are working with our supplier to understand their sourcing. The seal on the lid is plastic; we are testing alternatives." She removes "eco-friendly" and "sustainable", and records the evidence for each statement, with dates and supplier confirmations.

Sales stay steady, and customers write to say they appreciate the honesty. A competitor's complaint about a different brand's claims does not touch her.

Common mistakes

1. Vague words like "eco" and "green".
2. Claims with no evidence.
3. Highlighting one good feature and hiding a larger problem.
4. Invented badges.
5. Imagery that implies more than the facts.
6. Out-of-date claims.
7. Overpromising on the future.
