Werner & Mertz maintains intensive dialogues at various levels and establishes contacts: to companies, to nature conservation organisations and other associations.

The company is involved in cooperations and memberships, project partnerships and sponsoring relationships e.g. with:

Business in Good Company e.V.
Naturschutzbund Deutschland e.V.
EMAS Club Europe e.V.
Alliance for Resource Conservation
Deutsche Tafel e.V.

Through our membership in the German Cosmetic, Toiletry, Perfumery, and Detergent Association we are represented in the European industry association A.I.S.E. and are signatories to the A.I.S.E. Charter for sustainable cleaning. In 2005 Werner & Mertz was the first medium-sized company to sign this voluntary commitment to sustainable washing and cleaning and pass the corresponding audit.
