According to the international standards ISO 14040-14044, LCA is a strategic technique to identify and quantify the potential environmental impacts associated with a product or a system throughout its life cycle. The common LCA framework (goal and scope definition, life cycle inventory, LCI, and life cycle impact assessment, LCIA), applies environmental mechanisms and characterization models to relate the LCI results to selected category indicators for a quantitative evaluation of environmental impacts. A fourth phase, i.e., interpretation, transversal to the previous three ensures consistency between the aims of the study and its execution to finally draw recommendations. In the following paragraphs, the four phases are described with reference to the LimoFish process.
