<p>PROBLEM TO BE SOLVED: To provide a more objective evaluation system, especially a system capable of objectively evaluating recycling, improved in sections such as 'distribution', 'setting system boundary' and 'setting using state and disposing state' which are susceptible to subjectivity of an evaluator in the system of life cycle assessment(LCA) to quantitatively show the total environmental load of products and services. SOLUTION: The conventional LCA has made evaluations based only on the data regarding the environmental load of an object product (or service). This system assumes a method to manufacture a product (or service) substituting the object product not by recycling or a process to manufacture plural products at a time and objectively distributes by using the environmental load data. The system also maintains and uses data, regarding the price of material input or output at each process for objectively setting the distribution and the system boundary. Plural values or functions according to the using state or the disposing state of the product (or service) are output for the conventional system, that outputs only one figure according to each environmental load item.</p> |
