Simulation of household factor X in Japan

While each home appliance is being improved in terms of eco-efficiency now, the increasing number and size of such products in the home might increase the environmental impact as a whole. So factor X on home appliances at a household with regard to both the \´prevention of global warming\´ and \´effective utilization of resources\´ (hereafter called household factor X) in 2003 comparing to 1990 in Japan was simulated using independently developed "Factor X Tool 2001". This is the first attempt anywhere in the world to perform such a calculation. The results are the GHG factor of 1.9 and the resource factor of 1.2 on a household. Although based on a restricted simulation model, these results could show the potential for realizing a "sustainable society" that involves the reduction of environmental impact at the same time as improving quality of life.
