RATING TECHNOLOGICAL APPLICATIONS BY USING LIFE CYCLE ASSESSMENT
RATING TECHNOLOGICAL APPLICATIONS BY USING LIFE CYCLE ASSESSMENT

Summary/Abstract: In order to optimize different technological applications it is necessary to clearly define the rating perspectives of the approached technologies. In order to carry out a holistic comprehensive rating the environmental perspective has to be considered as well, beside technical and economic points of view. Following this constraining conclusion it is necessary to carefully analyse and evaluate environmental impacts of technological applications. Currently there are scientific debates regarding assessing possibilities of different economic activities especially related to concrete methods used in this context. One of the most discussed and used tools is the Life Cycle Assessment (LCA), which will be presented, emphasing the offered possibilitiesto actually optimise technological applications from different points of view. It will be concluded that with the optimising goal this instrument can be used in different stages and for different phases in the life cycle of a product. Regarding currently car market debates an example will be presented considering a so-called „generic car” by taking into consideration two phases of the whole life cycle, i.e. phase of basic materials fabrication and phase of car utilization. Pollutants emissions in these two phases will be assessed and compared by an Aggregated Emission Indicator, AEI. The obtained results will be discussed and conclusions concerning the application potential of the presented methodology by using life cycle assessment will be drawn
