“…The standards provided by the International Organization for Standardization (ISO) describe the four main phases of an LCA: "goal and scope", "inventory analysis", "impact assessment," and "interpretation." These standards have been developed by the ISO/TC 207 Technical Committee and they are: UNI EN ISO 14040 (1998) [2,3], by which the principles and the requirements for an LCA study are established; UNI EN ISO 14041 (1999), in which the objective and the field of application are defined and an inventory analysis is performed; UNI EN ISO 14042 (2000), that evaluates impacts: in particular, the main impact categories to be taken into consideration are the use of resources, human health, and ecological consequences; finally, with the UNI EN ISO 14043 (2000), improvements are analyzed. According to the ISO standards on LCA, it can assist in: identifying opportunities to improve the environmental features of products at various points in their life cycle; decision making in industry, governmental or nongovernmental organizations (e.g., strategic planning, priority setting, product and process design or redesign); selection of relevant indicators of environmental performance, including measurement techniques; and marketing (e.g., an environmental claim, eco-labeling scheme, or environmental product declarations).…”
