Greenwashing: The Reputation and Legal Risks, and How to Avoid Them

Greenwashing is when a business makes its products, services or operations sound more environmentally friendly than they really are, through vague claims, cherry-picked facts or promises it can’t back up. It creates two kinds of risk: regulators in the US, UK and EU can act against misleading environmental claims, and customers who feel misled tend to say so loudly and publicly. The fix is simple to describe and harder to do: only make claims you can prove, say exactly what they cover, and correct them fast when they turn out to be wrong.

This guide explains what counts as greenwashing, what the main rules say in general terms, how to substantiate a claim before you publish it, and how to respond if someone accuses you.

What counts as greenwashing

Most greenwashing isn’t an outright lie. It’s a claim that is technically defensible but leaves a misleading overall impression. Regulators generally look at what a reasonable customer would take away from the claim, not just the literal words.

• Vague, sweeping terms. “Eco-friendly”, “green”, “sustainable”, “natural” or “planet positive” with nothing to show what they mean.
• Hidden trade-offs. Highlighting one good attribute, such as recycled packaging, while the product’s bigger impact goes unmentioned.
• Claims without evidence. Saying something is “100% recyclable” or “carbon neutral” without data, testing or a clear method behind it.
• Irrelevant claims. Promoting something that is true but meaningless, such as being free of a substance that is already banned or never used in that category.
• Whole-product claims for part of a product. Calling a product “recycled” when only the cap is.
• Misleading imagery and labels. Leaves, globes and green colors that imply an environmental benefit, or self-made badges that look like independent certifications.
• Distant future promises. “Net zero by 2040” with no plan, interim targets or progress reporting.

A related problem is claiming a product is recyclable when few places can actually recycle it. The claim may be true in a lab and false for most of your customers.

The rules, in general terms

Environmental claims are covered by the same broad principle as other advertising: they must be truthful, not misleading, and backed by evidence before you make them. Several regulators have published specific guidance.

Where	Main guidance	What it says, broadly
United States	The FTC’s Green Guides	How the FTC applies its rules against deceptive advertising to environmental claims such as “recyclable”, “compostable”, “carbon offset” and general “eco-friendly” wording. Claims need competent and reliable evidence, and broad claims are hard to substantiate.
United Kingdom	The CMA’s Green Claims Code	Principles for environmental claims: be truthful and accurate, clear and unambiguous, don’t omit important information, make fair comparisons, consider the full life cycle, and be able to substantiate the claim.
European Union	EU consumer protection rules on environmental claims	The EU has been tightening its rules, with particular attention on generic claims like “eco-friendly” and on sustainability labels that aren’t based on a recognized scheme.

These are summaries, not legal advice. The details differ by country and change over time, and some states and industries have their own rules. If you sell across borders or make claims about carbon, recycling or offsets, have a lawyer who knows advertising law review them.

Beyond regulators, greenwashing claims can come from competitors, consumer groups, journalists and customers themselves. The legal process may take a long time. The reputational hit usually starts the day someone posts about it.

Why greenwashing hurts your reputation

A green claim is a trust claim. Customers who choose you partly for environmental reasons feel personally misled when the claim falls apart, and that sense of betrayal is what drives angry reviews, social posts and press coverage.

• It spreads well. A photo of a “plastic-free” product wrapped in plastic is simple, visual and easy to share.
• It sticks in search results. Articles about a greenwashing complaint can rank for your brand name long after you fix the claim.
• It spills onto other claims. Once one claim is shown to be misleading, people start doubting your quality, pricing and safety claims too.
• It affects hiring. Employees and candidates who care about the issue may raise it on employer review sites.

Greenwashing often grows out of a genuine corporate social responsibility program that marketing described too generously. The underlying work may be real. The overstatement is what does the damage.

How to make environmental claims you can substantiate

The safest approach is to treat every environmental claim like a factual statement you may one day have to defend in writing.

1. Start with the evidence, not the slogan. List what you can actually measure: the share of recycled content, the energy source for a facility, the results of a specific test. Write claims from that list.
2. Be specific. “Made with 50% recycled plastic” is stronger and safer than “eco-friendly packaging”. Say which part of the product the claim covers.
3. Qualify clearly. If a package is recyclable only where facilities exist, say so near the claim, not in small print on another page.
4. Think about the whole life cycle. Ask whether a claim about one stage hides a bigger impact at another, such as manufacturing or shipping.
5. Be careful with carbon and offset claims. Explain what “carbon neutral” covers, whether it relies on offsets, and what kind. These are among the most scrutinized claims.
6. Use real certifications only. Refer to independent schemes accurately and don’t design your own badge that looks like one.
7. Give future targets a plan. If you publish a target, publish the steps, interim milestones and progress, and update them.
8. Keep a claims file. For every claim, record the wording, where it appears, the evidence, who approved it and when it was last checked.
9. Review claims regularly. Suppliers, materials and facilities change. A claim that was true two years ago may not be now.

A worked example

This is an illustrative scenario, not a real client. A small coffee brand sells pods labeled “compostable” and “zero waste”. A customer posts a video showing that her city’s composting program doesn’t accept them and asks why the packaging claims otherwise. The post gets shared widely by people who care about packaging waste.

The brand checks its claims file. The pods do meet an industrial composting standard, but most customers don’t have access to industrial composting, and “zero waste” had no basis at all. It was a line from an old campaign.

Within a day, it posts a short response acknowledging the customer was right to question the label. It explains that the pods are designed for industrial composting, not home or most city programs, and that “zero waste” should not have been used. It commits to new packaging wording by a stated date, removes “zero waste” from its website immediately, and adds a page explaining what the pods can and can’t do. The criticism doesn’t vanish, but the story becomes “brand corrects its label” rather than “brand caught misleading customers”.

How to respond if you’re accused of greenwashing

An accusation can come from a customer post, a news story, a campaign group or a regulator’s letter. The first steps are similar, but a regulatory or legal complaint needs a lawyer involved before you say anything public.

1. Don’t react defensively. Avoid a quick denial you haven’t checked. A denial that later proves wrong is far worse than a short pause.
2. Pull the claims file. Find exactly what was claimed, where, and what evidence supports it.
3. Decide honestly which situation you’re in. The claim is accurate and misunderstood, the claim is accurate but poorly worded, or the claim is wrong.
4. Issue a holding statement if the story is spreading. Acknowledge the concern and say when you’ll respond fully. Our guide on how to write a holding statement has templates.
5. If the claim is accurate, show your evidence. Publish it plainly: the test, the standard, the numbers. Clarify the wording if it caused the confusion.
6. If the claim is wrong or overstated, correct it. Remove or change it everywhere it appears, including packaging schedules, ads and product listings, and say so publicly. Apologize if customers were misled.
7. Tell the people who need to know. Retailers, distributors and staff who repeat the claim need the updated wording.
8. Follow through and report back. If you promised new packaging or new data, publish it when it’s ready.

If the accusation includes statements about you that are false, not just critical, keep a record and talk to a lawyer before responding. Our guide on handling negative press coverage covers working with journalists who are writing about it.

Common mistakes

• Letting marketing write claims without evidence. Claims should be checked by whoever owns the underlying data.
• Overcorrecting into silence. Some businesses respond to greenwashing risk by saying nothing about genuine improvements. Specific, supported claims are still worth making.
• Quietly deleting a claim. People screenshot. A claim that vanishes without explanation can look like an admission with no apology.
• Arguing with critics online. Answer once, clearly, with evidence, then let the facts do the work.
• Threatening the critic. Legal threats against customers who question a claim tend to spread the original complaint further.
• Treating it as a PR problem only. If the product or process doesn’t match the claim, fix the product, the process or the claim.

When to get help

Most claims problems start and end with better wording and better records, which you can handle internally. Get a lawyer involved if a regulator or competitor contacts you or you face a lawsuit. Consider outside support if the story is spreading across news and social media or appearing in your search results. Our online reputation crisis management service can help you respond, monitor the fallout and publish accurate information that ranks.

Frequently asked questions

What is an example of greenwashing?

Common examples include calling a product “eco-friendly” with no explanation, labeling packaging “recyclable” when most local programs can’t take it, calling a product “recycled” when only one part is, and promoting a net-zero target with no plan or progress reporting.

Is greenwashing illegal?

Misleading environmental claims can break advertising and consumer protection laws in the US, UK, EU and elsewhere. Regulators such as the FTC and the UK’s CMA have published guidance on environmental claims. Whether a specific claim is unlawful depends on the facts and the jurisdiction, so talk to a lawyer about your situation.

Can small businesses be accused of greenwashing?

Yes. The rules apply to any business making environmental claims, and customers call out small brands as readily as large ones. Smaller businesses often have an advantage, though: they can check and fix their claims quickly.

Should we stop making environmental claims altogether?

Not necessarily. Specific, accurate claims you can support are useful to customers. The goal is to drop vague or unproven claims, not to hide real improvements.
