Abstract
A sustainable society can be created by establishing a positive feedback loop of the supply of Green Products and Services (hereafter called GPs) by businesses that will be able to contribute to the creation of a sustainable society and demand of GPs by users (customers). In order to promote the development of GPs and the diffusion of GPs, easily understandable criteria for judging GPs that can be shared among “designers and developers”, “managers” and “users (customers) ” are necessary. However there is no general means of measuring and evaluating specific target products, and the standard assessment method is yet to be established. Therefore, the “Factor X Tool 2001” independently developed as a GP indicator is proposed in this paper. And the way to calculate 'Factor X' ('Eco-efficiency') is explained by using the case study of applying “Factor X Tool 2001” to washing machines. After that, this paper verifies the effectiveness of this indicator by comparing with the Factor X calculation method developed by Mitsubishi Electric Corporation that has publicized calculated Factor values in the electric and electronic industry.
