Prototipi calzature alta moda basati su design innovativo ed eco-comaptibile

The quantitative environmental performance based on comparative life cycle assessment (LCA) constitutes an increasing area of interest for the suppliers competitiveness in the product chain. However the sources of uncertainties still constitute a relevant barrier for the full LCA utilization. Such reduced precision may invalidate the whole reliability in the comparison of environmental impacts for different products. Using standard modules of information for single life cycle stages this paper presents a systematic methodology for the application of an independent information modules approach (IIMs) in order to deal with the complexity in manufacturing chains. Such approach requires a dedicated modular description both for the enterprise activity and for the supply framework conditions. The resulting description is "firm specific" and based on shared assumptions in order to be rapidly reusable. A case study was carried out in the footwear chain for different products. Findings of this preliminary study show that the clear definition of relevant parameters can limit the redundancies in LCAs and firm efforts in the inventory of consumption and emission patterns. Further deepening of such methodology can introduce an integration of attributional and consequential LCA approaches by emphasizing the dependencies between product life cycle scenarios and the resulting impacts.
