For integrating Life Cycle Assessment into the design process it is more and more necessary to generate models of single life cycle steps respectively manufacturing processes. For that reason it is indispensable to develop parametric processes. With such disposed processes the aim could only be to provide a tool where parametric environmental process models are available for a designer. With such a tool and the included models a designer will have the possibility to make an estimation of the probable energy consumption and needed additive materials for the applied manufacturing technology. Likewise if he has from the technical point of view the opportunity, he can shift the applied joining technology in the design phase by changing for instance the design.

The basis for an environmental benign design of the production is the knowledge of the environmental impacts of processes. By setting up an Environmental Knowledge Management System (EKMS) the perception can be organized. The application of the EKMS is divided into two steps: 1. Documentation of the actual state with the focus on data collection and modeling of technical systems (production of products). 2. Derive from prognostic statements by means of evaluated data and the identification of potentials for optimizations. The implementation and updating lays the foundations for the environmental optimization of the planning, development and production. The target is to ensure the availability of environmental information in the entire product developing process. The decision maker can identify optimization potentials with the help of this system already in an early stage of the product development process.
