Theme 4 — Claims, greenwashing and enforcement

From environmental message to enforceable representation

Packaging law determines many of the statements that must appear on a pack, but it is often consumer-protection, competition and advertising law that determines what else may be said. A claim can be factually related to the package and still mislead because it is too broad, omits a material condition, relies on an unsuitable comparison, projects an unsupported future outcome or uses a certification mark beyond the scope of the certificate.

This theme follows the full enforcement chain. It begins with the words, symbols and implied messages visible to the audience; identifies the evidence needed to support them; and then examines the public authorities, courts, competitors and private claimants able to test the representation. The analysis separates binding law from regulator guidance and distinguishes a defensible technical proposition from the broader impression created by the package as a whole.

Legal status remains central. The section does not treat a legislative proposal as an existing prohibition or assume that the failure of one proposal leaves a legal vacuum. It records which general rules already apply, what later measures will change, and where national authorities are developing their own approaches.
