Method and system for calculating environmental impacts of products

摘要

An environmental impact calculation system comprises a plurality of measuring instruments (10 to 21), a plurality of flowmeters (9a to 9d) and a production management system (22). The measuring instruments measure environmental impacts of products that are produced in a manufacturing process. The flowmeters specify a proportional distribution parameter for proportionally distributing environmental impacts associated with plural types of products that have been measured by the measuring instruments to environmental impacts associated with PCB products. The production management system specifies a distribution parameter for distributing the proportionally distributed environmental impacts to one product. <IMAGE>
