The NF Environnement mark is a voluntary certification mark issued by AFNOR Certification.

This mark, which was created in 1991, is the official French ecological certification.

It is awarded to products that have a reduced effect on the environment while offering an equivalent performance.

To be issued the NF Environnement mark, the product must comply with ecological and fitness for purpose criteria. These criteria are the result of negotiations between representatives of manufacturers, consumer, environmental protection and distributor associations and public authorities.
