Suppliers should support the sensible and responsible use of resources. As part of the production process therefore, they should factor in the limited availability of natural resources (e.g. water), environmental influences on production (e.g. climate), the possibility of production-related environmental impact (e.g. noise, waste, waste water), as well the waste management infrastructure (e.g. waste disposal and recycling). Furthermore the supplier will promote the process for an effective energy management.
Deliveries within the serial production process must be performed with a "zero-defect-quality". Suppliers must also provide a 100% service rate, which is expressed in maximum responsiveness and a positive attitude.
