# Advertising greenwashing: legal framework and best practices

**In short:** greenwashing means giving a misleading ecological image to a product or brand. It is both a **legal risk** (misleading claims) and a major **reputational risk**. The golden rule: an environmental claim must be **proven**.

## What is greenwashing?
Greenwashing occurs when communication exaggerates, invents or blurs an environmental quality: vague words ("eco", "green", "natural") without proof, misleading visuals, or highlighting one virtuous detail that masks an overall negative impact.

## The framework in France
Misleading advertising is governed by consumer law. In addition, the **Climate and Resilience law** (2021) strengthened the framing of environmental claims and introduced measures such as the ban on advertising for **fossil fuels** (in force since 25 August 2022). The ARPP also issues ethical rules on environmental claims.

## Risky claims
- Vague, unjustified terms ("environmentally friendly").
- Global claims based on one aspect ("recyclable" when the rest isn't).
- Nature-evoking visuals with no basis.
- Offsets presented as full neutrality without proof.

## Best practices
- **Prove** each claim (data, recognised labels, life cycle).
- **Be specific**: which benefit, over what scope?
- **Avoid** unsupported superlatives.
- **Document**: keep evidence in case of checks.

## FAQ
**Is greenwashing illegal?**
A misleading environmental claim can fall under misleading advertising, which is punishable. The framework has tightened, notably with the Climate law.

**How to avoid greenwashing?**
Only communicate real, proven, specific benefits, without exaggeration or unjustified vague terms.

**Can you call a product "eco-friendly"?**
Only if justified and specific. Global, vague claims are especially risky.
