What Is Greenwashing?

Greenwashing is the gap between what an environmental claim appears to mean and what the available evidence actually demonstrates -- not every vague claim is deliberate deception.

Plain-English Definition

Greenwashing describes marketing that creates an impression of environmental responsibility that isn't supported by the evidence, whether through vague language, irrelevant claims, hidden tradeoffs, or unsupported certifications.

What the Claim Usually Means

The term is often used as a blanket accusation of dishonesty. In practice, greenwashing exists on a spectrum from genuinely deceptive marketing to overly optimistic but not deliberately false framing.

What It Actually Proves

Recognizing greenwashing patterns helps identify where a claim is likely to be weaker than it sounds, so you know what to ask before trusting it.

What It Does Not Prove

Spotting a greenwashing pattern doesn't prove a specific company is acting in bad faith. Vague language is sometimes just poor communication rather than intentional deception.

How It Is Measured

There's no formal greenwashing score. Regulators like the FTC (U.S.) and the CMA (U.K.) publish guidance describing specific deceptive patterns, which is the basis for the pattern categories used on this site.

Common Misunderstandings

  • That greenwashing always means an outright lie -- most cases involve selective framing, not fabrication.
  • That a single greenwashing pattern found on a product means the whole company is acting in bad faith.
  • That greenwashing is only about words -- imagery and design choices are common vectors too.
