From 27 September 2026, advertising using "sustainable", "environmentally friendly" or "green" will only be permitted if every claim is substantiated directly on the advertising medium with concrete evidence. This page sets out the four core principles of the evidence obligation and ranks the cease-and-desist risk per advertising channel.
Last update: 26 May 2026
Generic terms such as "sustainable" or "environmentally friendly" must be replaced with concrete, measurable properties — e.g. "80% less water consumption in production compared with 2019".
Evidence must be accessible directly on the same web page or advertising medium — not a reference to a 200-page sustainability document, but inline links to the standard, certificate and methodology.
Anyone who actually reduces part of their emissions and offsets another part must communicate both openly. Merging the two figures is misleading.
In-house "eco" labels and self-certifications are banned from 2026 if they suggest a third-party seal. Only accredited seals are reliable (Blue Angel, EU Ecolabel, FSC, GOTS).
Highest risk of a cease-and-desist letter. Product copy, category pages, marketing banners and about pages are systematically screened by competition associations.
Greatly underestimated. Blanket claims in image captions or story texts are increasingly being monitored by consumer protection associations.
Long production cycles — changes require a lead time of 6–12 months. Existing stock can become a cease-and-desist trap from 27 September 2026.
Medium risk due to limited reach, but high public visibility — flawed campaigns are picked up by the trade press.
Low but steadily rising risk. Competition associations systematically subscribe to the newsletters of competing brands.
Only in combination with concrete evidence. "Sustainably produced" on its own is prohibited — "produced and certified to the GOTS standard (certificate no. XY)" is permitted. Rule of thumb: every blanket term must be backed up on the same page by a verifiable fact.
Recognised standards (ISO 14040 LCA, GHG Protocol, EN 13432, GOTS, FSC), independent certifications (Blue Angel, EU Ecolabel, Demeter, Naturland) and scientific studies with a citable source. Your own calculations without external verification are not enough.
Terms with no direct environmental reference do not fall under the EmpCo rules. But if a claim implicitly implies an environmental benefit ("regional = sustainable"), it counts as an environmental claim and is subject to the corresponding requirements.
