Green claims in ads (carbon neutral, green, sustainable, eco-friendly) are under growing scrutiny. The European directive on empowering consumers for the green transition restricts generic, unsubstantiated claims, and advertising authorities already apply these requirements.
The essentials in a definition
Green claims in ads are statements about the environmental impact of a product, service or brand. The directive on empowering consumers and the Unfair Commercial Practices Directive require them to be specific, true and provable, and restrict generic ones.
What changes
The directive on empowering consumers for the green transition amends the Unfair Commercial Practices Directive and identifies as prohibited practices, among others, generic environmental claims without recognised excellent environmental performance to back them, and claims about the whole product when they apply only to part of it. Consult the current text and application dates.
Claims based on emissions offsetting to say a product has a neutral or reduced impact are also restricted under the conditions provided.
Generic claims
Terms such as “eco” or “environmentally friendly” without specification are the riskiest. Prefer saying what is concrete and verifiable: recycled material at a proven percentage, plastic-free packaging, a recognised and identifiable certification. If you cannot prove it, do not say it.
Bodies such as the ASA in the UK and national EU authorities publish rulings and guidance that show how these rules are applied.
Checking a green claim before publishing it
- Identify the exact claim
- Gather verifiable evidence
- Use specific wording
- Review existing ads and pages
Evidence and labels
Keep a file with evidence for each claim: suppliers, tests, certifications and methodology. Sustainability labels should be based on recognised certification schemes or public authorities, not on seals created by the brand without verification.
Update the evidence when the product or supplier changes.
A green claim is worth the evidence behind it.
Internal process
Include an environmental-claims check in the ad approval flow. Train teams and agencies, and define who approves. Review old ads and pages to remove claims you can no longer support.
When in doubt, opt for a more modest and specific wording.
Decision table
| Claim type | Risk | Practice |
|---|---|---|
| Generic (“eco”) | High | Avoid or specify and prove |
| Specific and proven | Low | Point to the evidence accessibly |
| Neutrality by offsetting | High | Confirm legal conditions |
| Own label | Medium to high | Use recognised certifications |
Common mistakes to avoid
- Vague claims. They are the most sanctioned.
- Applying the claim to the whole product. When it applies to only a part, it is misleading.
- Not keeping evidence. Without evidence, the claim does not hold.
How to measure the result
Count active environmental claims, those with documented evidence and related complaints or disapprovals.
Limits and exceptions
Transposition and application of the directive vary by country and have different dates, and this content is informational and does not replace legal advice. Interpretation evolves with authorities’ decisions. When in doubt, opt for the most cautious wording and consult a professional.
Illustrative example
Illustrative example: a cleaning brand replaces “100% eco” with “packaging made with certified recycled plastic” and “biodegradable formula, per standardised test”, linking to the documentation. It withdraws old ads with generic claims. The risk of complaints falls and the message becomes more concrete.
In practice: checkpoints
Keep claims specific, keep the evidence in an accessible file with dates, and review ads and pages when products, suppliers or laws change.
Frequently asked questions
Can I say “sustainable”?
Generic terms are risky; be specific and prove each aspect.
Does carbon offsetting allow saying “neutral”?
It is restricted under conditions in the regulation; confirm the applicable text.
Do own seals work?
Seals without independent verification are problematic.
Who can verify claims?
Laboratories, recognised certification bodies and, internally, a compliance function.
What if a competitor uses generic terms?
The risk is yours; comply with the rules instead of aligning with questionable practices.
Support every green claim with evidence, be specific instead of generic and keep a verification process before publishing.
