1. Background
Carbon dioxide ( CO2 ) emissions, which cause global warming, occur in various situations in home life. It is therefore important to reduce CO2 emissions by leading an environmentally conscious energy-saving lifestyle.

The "Environmental Household Account Book" provides one way to review one's lifestyle. The households which participate in the program find out the amount of CO2 emissions in their home life by recording the consumption of electricity and gas.
