tions systematically throughout a product’s value chain. The environmental assessment methods focused solely on the environmental indicators and they were based on material and energy balances. Production-oriented assessment methods including discrete event simulation and value-stream mapping focus on time and volumes but can be employed in light environmental assessments, adding environmental indicators into the assessment. They commonly focus on the production floor operations. In spite of the method looked at, careful consideration of the objectives and the use of applications are determinants. In the Ekoteho project, four industrial case studies were completed and a new methodology, ECOmap, created and tested. Four confidential industrial case studies were carried out, and the final research report, four conference papers and one master’s thesis resulted from the project. The ECOmap, shown in Figure 2, works on an existing commercial software platform, eVSM, and uses the process flow chart and worksheet. It is a simplified and connective process flow chart method. The platform uses pre-selected indicators. The method uses a limited number of visible parameters. The plat-

form has connections to web databases to import data.

Discussion and exploitation potential It is becoming more important to control environmental impacts in the manufacturing industry, as the goal is shifting from conventional end-of-pipe technology to life cycle thinking. This shift can be accelerated with the right tools and methods. Manufacturing systems, processes, products and related data are becoming more complex. Thus, product and manufacturing engineering and production management decisions require many interdependent factors and variables to be considered. To be able to consider the environmental impacts of a production process, it is important to assess the environmental parameters simultaneously in the same model along with the process parameters. Thus, the environmental considerations can be made in conjunction with production system planning. The development of a sustainable manufacturing system adds parameters that must be handled simultaneously. To incorporate environmental considerations while analysing manufacturing systems,
