The association brings together the key players in the green roofing industry (manufacturers, building and landscaping contractors, professional associations, etc.). It recently expanded to encompass the green wall industry, a sector in which many of its members have been present for several years. Concerning roofing , the hard work and dedication of the association and its members in recent years (training/information/experimentation) has resulted in a boom in green roofs in France, with more than one million square metres installed in 2011. ADIVET is also recognized as a reference organization in its field and is co-editor of the French Professional Standards for Green Roofs and Terraces together with the UNEP (National Union of Landscaping Companies) and the CSFE (French Waterproofing Association).
