A label is a collective mark with its own name and logo, used by companies, brands or products which comply with the label's specifications. The aim is to clearly certify certain specific advantages and characteristics. A labelling scheme may be run privately (managed by a producer association, for example) or by a public body.
For example, the NF Environnement label, an official green label owned and managed by Afnor, the French standardisation body, applies to products which have a reduced environmental impact. It guarantees both the product's reduced environmental impact and its quality of use. Labelling criteria are defined in partnership with the public authorities and award of the label is conditional on certification by an acknowledged independent body.
