Greenwashing explained: how to spot it

Greenwashing wastes your money and effort, and erodes trust in brands and claims that are genuinely trying to do better. Learning to spot it quickly is a useful, transferable skill — not a reason to become cynical about all environmental claims.

What greenwashing actually is

Greenwashing is when a company, product, policy or investment is presented as more environmentally responsible than it really is. The term was coined in the 1980s and covers a wide spectrum — from a minor exaggeration on a shampoo bottle to a major corporation making sweeping climate commitments while continuing to expand fossil fuel extraction.

It is not always deliberate deception. Sometimes marketing teams reach for environmental language without fully understanding whether the claims are accurate. But the effect is the same: you make purchasing decisions based on a misleading picture.

Greenwashing is increasingly regulated in some countries — advertising standards bodies in a growing number of markets have issued guidance or taken action against unsubstantiated environmental claims. But regulation varies, and plenty of vague language still slips through.

Why it matters

• It wastes your money. You may pay a premium for a product presented as sustainable when it offers no meaningful advantage over the alternative.
• It wastes your effort. If you're trying to make better choices, greenwashing sends you in the wrong direction.
• It erodes trust. Repeated exposure to hollow claims makes it harder to take genuine environmental commitments seriously — which benefits no one.
• It can crowd out the real thing. When any brand can call itself "eco-friendly" without evidence, companies that have invested seriously in improvement lose their competitive advantage.

Common tactics

Vague buzzwords

Words like "eco," "natural," "green," "conscious," "responsible," "planet-friendly" and "sustainable" have no universal legal definition in most markets. They can appear on almost anything without substantiation. A cleaning product can be labelled "natural" while containing ingredients with significant environmental effects. The word alone tells you nothing — look for specifics.

Hidden trade-offs

A product is highlighted for one green feature while everything else about it is ignored. A clothing brand might promote a small range made from recycled fibres while its main production line uses environmentally intensive processes and fast-fashion volumes. Evaluate the whole product and the whole company, not just the headline claim.

Irrelevant or obvious claims

Labelling a product "CFC-free" when CFCs were banned decades ago and were never in that type of product anyway. "Plastic-free" on items that would never have contained plastic. "Free from artificial colours" on a product where artificial colours would be illegal. These claims are technically true but designed to create a halo of environmental virtue where none applies.

Fake or unclear certification

A logo or certification mark that looks official but was designed by the company itself and refers to no external standard or auditing process. Or a reference to a real certification scheme that turns out, on inspection, to apply only to one ingredient or one factory. Real certification schemes are transparent — you can look them up and find their standards and who does the auditing.

Misleading imagery

Lush greenery, pristine mountains, clear water or baby animals on packaging or in advertising create an emotional sense of environmental care that may have no connection to how the product is made. Imagery is not a claim, so it is harder to regulate — but it is one of the most effective tools in greenwashing.

Carbon-neutral and net-zero claims

These claims deserve particular attention because they have become widespread and the methodology behind them varies enormously. "Carbon neutral" and "net zero" should mean that verified, measurable emissions reductions — plus any high-quality remaining offsets — bring total net emissions to zero or near it.

In practice, many such claims rely heavily on carbon offsets of variable quality, use narrow accounting that covers only part of a company's emissions (for example, direct operations but not supply chain or product use), or have not been independently verified. Some targets are set decades in the future with little action committed in the near term.

A credible claim will specify the scope of emissions covered, the methodology used, who independently verified it, and what proportion represents genuine emissions reduction versus offsetting. See our explainer on carbon offsetting for more on what good and poor offset quality looks like.

How to see through it

• Ask: what specifically? Vague language should be replaceable with specifics. If it isn't, that's telling. "Made with sustainable materials" — which materials? What standard defines them as sustainable? Who verified it?
• Look for recognised third-party certification. Independent bodies with published standards and auditing — FSC for wood and paper, EU Ecolabel, recognised energy ratings, B Corp for company-level practice — carry more weight than self-declared claims. You can verify these bodies are real and check their standards.
• Think whole-product and whole-company. One recycled-content detail does not define a product. One green initiative does not define a company. Look at the full picture of what is being sold and how it is made.
• Check transparency. Companies serious about environmental performance tend to publish detailed sustainability reports, with numbers, scope descriptions and third-party verification. The absence of this information in a company making strong claims is itself a signal.
• Is the company helping you buy less and use longer? A brand that offers repair services, sell-back or take-back, long warranties, modular design, or that openly encourages you to buy second-hand instead (see our guide to buying secondhand) is demonstrating a genuine alignment between its business model and sustainability — unlike brands that rely on constant new purchasing.

Red-flag checklist

• Vague words with no supporting evidence: "eco," "natural," "green," "conscious," "responsible."
• A self-made certification or logo with no reference to an independent standard.
• One green feature highlighted while the rest of the product or company is ignored.
• Irrelevant claims ("CFC-free," "no added hormones") that don't apply to the product category.
• "Carbon neutral" or "net zero" with no scope, methodology or verification stated.
• Distant sustainability targets with no concrete near-term actions or milestones.
• Green and nature imagery with no substantive environmental claims beneath it.
• A company that profits primarily from high volumes and short product lifespans calling itself sustainable.
