Life cycle analysis scope definition

A LCA consists of four independent elements that is, (i) the definition of goal and scope, (ii) the life cycle inventory analysis, (iii) the LCIA, and (iv) the life cycle interpretation. The definition of the goal and scope (i) includes a decision about the functional unit that forms the basis of comparison, the product system to be studied, system boundaries, allocation procedures, assumptions made, and limitations.

An inventory analysis compiles the flows of materials and energy into and out of the system. Necessary work consists of construction of a flow model, data collection, and calculation of results. In other words, the phase of life-cycle inventory (LCI) provides the systems model of the technical system ( product system ) under study, complying with the goal and scope definition. This model consists of certain elements, which in terminology of the ISO standards are the following ... 

The goal and scope definition stage is then followed by a life cycle inventory analysis. In the life cycle inventory analysis stage, data on raw materials and energy consumption, emissions, waste, monetary flows, and social issues are collected. While data on raw material inputs, environmental outputs, and monetary flows are quantitative, data on social issues are in forms of both quantitative (e.g., number of working hours, amount of child labor) and qualitative (e.g., risk ofpubhc resistance to the prospective product, risk... 

The International Standard Organization (ISO 14040) [26] breaks the LCA framework into four main stages (1) Goal and scope definition of the study. This stage clarifies the purposes of carrying the study while the assumptions and system boundaries are described clearly. (2) Life Cycle Inventory (LCI) analysis. LCI involves data collection and calculation procedures to quantify relevant inputs and outputs of the entire system defined within the system boundaries. (3) Life cycle impact assessment involves qualifying the potential environmental impacts of the inventory analysis results. (4) The interpretation of the results from the previous phases of the study in relation to the objective of the study. This interpretation can be in form of conclusions and recommendations to decision-makers for process changes to deliver improvement in the environmentel performance.
