Ecolabel, quality mark, test seal, environmental label: what is the difference?

In everyday use the four words are interchangeable. None of them is legally protected, and none of them says on its own who did the assessing. There is still a difference in emphasis.

What each term stresses

Ecolabel is the narrowest term. It usually means the state-backed marks such as the Blue Angel or the EU Ecolabel, which assess a product across its whole life cycle.

Environmental label and sustainability label are umbrella terms for any mark confirming an environmental or sustainability property. A single attribute such as a recycled content falls under them too.

Quality mark is not limited to the environment. It also covers safety, as with the German GS mark, origin, or how an online shop handles a purchase.

Test seal stresses that an assessment took place. The word does not say who assessed. A manufacturer testing its own product can put such a mark on the pack as well.

The distinction that actually matters

The ISO 14020 series is sounder than the vocabulary:

Type I under ISO 14024. A programme with published criteria, assessed and awarded by a body that does not itself sell the product. The Blue Angel and the EU Ecolabel belong here.

Type II under ISO 14021. A self-declared claim by the manufacturer, for example „recyclable“ on its own packaging. This is exactly what the EmpCo Directive restricts from 27 September 2026.

Type III under ISO 14025. An environmental declaration with life-cycle figures, without judging whether those figures are good or bad. Known as an EPD in construction.

Where the flustix trustmarks sit

The flustix trustmarks are third-party marks. Material analysis is carried out by laboratories accredited to ISO/IEC 17025, and conformity is assessed by certification partners accredited to ISO/IEC 17065. flustix does not assess its own marks. How that works in detail is set out in the certification process. Every certificate carries a licence number and can be looked up in the public database.
