What is greenwashing? It is the practice of making environmental claims that mislead, by overstating, blurring or hiding the truth about the climate and environmental impact of a product, service or company.
This page is independent and informational. It explains how to read green claims and links to the underlying rules, starting from the basics in what is a carbon footprint, and it does not certify or rate any company.
Greenwashing defined
The term is now used in law as well as in everyday speech. The EU directive on empowering consumers for the green transition refers to misleading environmental claims (‘greenwashing’) among the practices that national bodies should be able to address. In that sense a claim does not have to be false to mislead: it can be technically accurate yet leave a reader with an inaccurate impression.
Researchers who study carbon markets use the same word. The University of Oxford’s offsetting principles warn that if not done well, offsetting can result in ‘greenwashing’ and create unintended negative impacts for both people and the environment. The concern is therefore broader than advertising slogans.
Vague and generic claims
The most common pattern is a broad word with no explanation. The EU directive lists ‘environmentally friendly’, ‘eco-friendly’ and ‘green’ among its examples of generic environmental claims, which it restricts unless the trader can show recognised excellent environmental performance relevant to the claim.
United States rules take a comparable view. The Federal Trade Commission’s Green Guides, as published in the federal regulations, state that unqualified general environmental benefit claims are difficult to interpret and likely convey a wide range of meanings. The guidance says marketers should qualify such claims with clear and prominent language limited to a specific benefit.
The UK’s competition authority makes the same point in its Green Claims Code: vague and general statements of environmental benefit are more likely to be misleading. A specific statement, such as which part of a product is recycled and how much, gives the reader something to check.
Selective and incomplete claims
A second pattern is picking the flattering fact and leaving out the rest. The UK guidance gives an example: if a courier company claims that it is investing 10% more in electric vehicles, but does not disclose that it is also investing 40% more in diesel vehicles, this would be a significant omission liable to mislead consumers. The same code states that claims must not omit or hide important relevant information.
The boundary of a claim matters in the same way. A company may report progress on emissions from its own sites while saying little about those from its supply chain. The guide to scope 1 2 and 3 emissions explains how those categories divide an organisation’s footprint, and the Oxford principles stress that organisations must focus on urgently reducing emissions within their value chain, not only inside their own walls.
Labels, offsets and future pledges
Labels and self-made badges can imply an independent check that does not exist. The EU directive describes the target of its rules as including non-transparent and non-credible sustainability labels. A label is easier to rely on when it names who sets the criteria and who checks compliance.
Offsetting is another area of care. In the EU, claiming that a product has a neutral, reduced or positive impact on the environment based on offsetting is among the banned practices listed in the directive, which Member States were to apply from 27 September 2026. A business that makes public climate claims should check the advertising and consumer rules where it operates, because the details differ by country.
Why greenwashing matters
Misleading claims have a cost beyond the single purchase. Shoppers who pay extra for a product because of an environmental promise lose out if the promise is hollow, and companies that make accurate claims compete against those that do not. The EU directive explains that ensuring that environmental claims are fair, understandable and reliable lets traders operate on a level playing field, so consumers can choose products that are genuinely better for the environment.
There is a climate cost as well. When a broad green label makes a product sound harmless, attention moves away from the reductions that would actually lower emissions. A reader who believes a service is already neutral has little reason to ask what it has changed, and the pressure to cut emissions at source weakens.
Everyday examples show the difference. A product described as made with recycled materials, with the share stated and explained, can be checked against its packaging or a published report. A product described only as planet friendly offers nothing to check, and the reader must either trust the brand or ignore the claim. The first kind of statement invites scrutiny; the second avoids it. Asking for that kind of detail is a simple, practical habit for any reader.
For that reason, careful claims tend to share a few habits. They name the specific benefit, state the boundary, describe the period and method, and avoid implying more than the evidence supports. These habits cost little, and they are what separates a useful environmental statement from a slogan.
How to check a green claim
A short set of questions covers most cases:
- What exactly is claimed, and for which product, site or period?
- Is the wording specific enough to be tested, or is it a broad word such as green or eco?
- Does the claim leave out an important downside or a larger part of the footprint?
- Is a label or certificate named, with a published method and an independent body behind it?
- Does the claim lean on offsets, and if so is that stated clearly?
The UK Green Claims Code states that claims must be truthful and accurate, clear and unambiguous, and the same page lists comparisons, life cycle and substantiation as further tests. Readers can apply the same tests informally to any claim they meet.
For individuals, the most reliable approach is to look at actions that cut emissions directly. The guide to ways to reduce household carbon footprint shows where the larger savings usually lie, which makes it easier to judge whether a product’s green claim touches anything that matters.
Frequently asked questions
Is greenwashing always intentional?
Not necessarily. A claim can mislead through vague wording or missing context even when the business did not mean to deceive, and the rules in the UK and EU focus on the impression a claim gives to consumers.
Are words like eco-friendly banned?
In the EU, generic claims of that kind are restricted unless the trader can show recognised excellent environmental performance relevant to the claim. US guidance tells marketers not to make unqualified general claims. Rules differ by country.
Does carbon offsetting count as greenwashing?
Offsetting is not automatically greenwashing, but the Oxford principles warn that offsetting done badly can result in it. How a claim describes the offsets, and what it says about the company’s own reductions, matters most.
Where can a consumer look for specific information?
A trustworthy claim usually names what is covered, the period, the method and any independent body involved. If those are missing, the claim cannot easily be tested.
