ISO’s official catalogue shows that ISO 14021:2026 was published in June 2026. It addresses self-declared environmental claims for products, including labels and digital communications. The point is not to add more green words to a package, but to make every statement answer: which product, which attribute, under what boundary and with which evidence?
The first field group is the subject of the claim. “Less packaging” may refer to the bottle, cap, label, shipping case or dose; “contains recycled material” also needs to identify the relevant component and calculation basis. If the subject is unclear, consumers may read a local improvement as an overall product advantage.
The second group is scope and qualification. The FTC’s Green Guides summary warns that broad, unqualified environmental-benefit claims such as “green” or “eco-friendly” are difficult to substantiate. Qualifications should be clear, prominent and close to the claim. The UK CMA Green Claims Code likewise stresses accuracy, clarity, material information and evidence.
The third group is metric, method and baseline. A content, reduction or comparative claim should record the unit, calculation method, comparison product or year, life-cycle stage and data date. Without like-for-like evidence, adopting a particular design should not be extended into “lower carbon”, “greener” or overall-performance leadership.
The fourth group is evidence version and ownership. A change in formulation, packaging supplier, production version, market language or legal context may leave old evidence outside scope. The ledger should retain product ID, exact claim, qualification, evidence file, review date, owner, target market and reason for change.
EPHYON’s public ODM service places target market, category and scenario, formulation and dosage form, fragrance, sampling, packaging and scale-up review in one development entry point. These project nodes can index an environmental-claim ledger: lock the product and packaging versions before discussing external wording. The page does not prove any environmental certification or advantage for a specific product.
The EU UCPD, US FTC guidance, UK CMA principles and an ISO standard do not have the same legal status or scope. A marketing principle from one jurisdiction is not a universal compliance conclusion; a specific market still requires its mandatory rules, certification scheme and current evidence.
An executable review form therefore turns “what we want to say” into “how far the evidence lets us say it”. Check subject, boundary, metric, method, version, market and owner before deciding the headline, package copy and digital page. Restraint does not hide real strengths; it makes reliable facts traceable.
