The Council general-approach text defines an explicit environmental claim as an environmental claim made in written form or orally, including through audiovisual media, while excluding environmental labels. That captures text on packaging, product pages, ads, scripts, videos, sales pages, marketplace feeds, sustainability pages, and similar consumer-facing communications when the message says or implies an environmental advantage.
The related Directive (EU) 2024/825 definition is broader: an environmental claim can be any non-mandatory text, pictorial, graphic, or symbolic representation, including labels, brand names, company names, or product names, in a commercial communication. The Green Claims proposal then focuses on the explicit subset for substantiation, communication, and verification rules.
