Headnotes by the Editorial Office 1. When the designation of a certification includes an environmental claim, it is not sufficient to refer only briefly to third-party certification. 2. Although there may be exceptions, as a general rule, the meaning or significance of the certification must be made clear to consumers. 3. The information on third-party certification must be supplemented with information on the meaning of the certification in the immediate vicinity of the marketing claims. 4. Simply posting such information on one’s own website when marketing takes place elsewhere is insufficient. 5. Failure to inform about the meaning of the certification means that the marketing is misleading and, thus, also unfair.
