Protecting the environment has always been a major priority for Delor, who introduced waste sorting and recycling facilities back in 2001, and a water purification site in 2004.
To consolidate these practices, in 2012 Delor adopted the voluntary, collective Environmental Management System (EMS), spearheaded by the Conseil Interprofessionnel des Vins de Bordeaux. Bordeaux was the first wine-producing region to unite the entire wine industry around such an approach.
In 2013, the internationally recognised ISO 14001 certification acknowledged its commitment to an environmentally friendly approach.
