Green supply chain management much more than questionnaires and ISO 14.001

Green supply chain management goes clearly beyond substance questionnaires and ISO 14.001. In this paper it is demonstrated that supplier-producer cooperation in the fields of EcoDesign (Design for the Environment) and in benchmarking of manufacturing processes can yield impressive ecological and economic gains. Examples are shown in the fields of energy consumption of products, application of recycled material, take back and recycling and use of utilities in production. In all these fields it shows that "what is measured is better managed".
