Environmental information documenting apparatus and environmental information documenting method

An environmental information documenting method by which an environmental information documenting apparatus including:

• a storage unit that stores an evaluative information table, a transport information table, a product compositional information table, and an environmental load factor table, in each of which the cost and the scale of use of system products, each being a combination of plurality of hardware and/or software products, at different stages the life cycle thereof is assigned IDs sorted by product class, a shipping work information table in each record corresponds to one of the IDs, and a constituent elements information table, an evaluative information management table and a product evaluation result table;
• a control unit;
• and an input unit and an output unit that constitute user interfaces and performs communication with an external system,
• wherein the control unit executes the steps of:
• at least accepting from a user interface indicators representing the name of a product to be evaluated, the product field, the total cost of the product and the scale of use of the product, and extracting from the evaluative information table the record closest within a prescribed tolerance to the accepted product cost and scale of use;
• searching each table according to the ID of the extracted record, presenting to the user interfaces the cost of the pertinent system product at each stage of the life cycle thereof, accepting a corrected input from the user and recording the corrected cost;
• displaying a product use environmental load factor screen on the user interface, presenting information on the scale of use, the scale of use coefficient, and the initial value regarding factors including the number of man-hours worked, communicated data quantity, shift, consumed wattage and paper retrieved from the environmental load factor table and, after accepting a corrected input from the user, recording the data;
• searching each record in the constituent elements information table and the product compositional information table matching the record of the extracted evaluative information table, computing the environmental load at each stage of the life cycle, and creating a product evaluation result table for each stage of the life cycle for each evaluation class of the environmental load and the cost and for each unit of totalization of the constituents, the system and the total;
• and
• outputting a product evaluation output table screen from the output unit, arranging on the screen a selection button for the name of product to be evaluated, the environmental load and the cost on the screen, accepting the input of the selection made therewith, and displaying a graph of the environmental load or the cost at each stage of the life cycle and of the product use.
