Factors for One Household

Whilst we have made improvements in the Factor figures for each product, the number and size of products used at one household have both been increasing. As we are mainly engaged in the home appliance industry, we therefore believe it is important to evaluate the GHG and Resource Factors for One Household, targeting some 90 appliances or items of equipment commonly used in households.

Sample household
Family and house
We assumed a four-member, three-generation household with grandmother(70), father (40), mother (37) and daughter (6).The family live in a two-story house with 4 rooms and a living-dinning room, with total floor area of 136.9m2, the national average in Japan.
Products comprising the house
Fiscal 1991: The latest models that we produced and marketed at that time in consideration of market penetration
Fiscal 2007: The Latest products recommended by Panasonic in consideration of market penetration and changes in lifestyles (increase in the number and size of products used at a household)
