Methodology and utilization of simplified eco-assessments for policy making

Environmental policy making, green product rating, and marketing activities seem likely to drive the utilization of eco-assessments in the near future. In this paper we show from the example of EuP Preparatory Studies and other policy supporting studies some characteristics of ICT eco-assessments on different economical levels. We argue that the high diversity of individual cases coupled with technology dynamics, which characterize the ICT development, requires an adequate parameterization in the eco-assessments. We present the idea of a multi-level model that incorporates these aspects and could be used as an interface for different eco-assessment purposes.
