The construction of lifestyle for sustainable society - the calculation of consumer unit from household budget and CO_2 emission -

本研究利用“CO_2排放点表”数据和“1984年全国家庭收支调查”的原始数据，分析了家庭支出与CO_2排放之间的关系。结果表明，每对夫妇的二氧化碳排放量为1277 kg，其中一个孩子的二氧化碳排放量为188 kg，而另一个孩子的二氧化碳排放量为66 kg。交通通信、食品、燃料、电费和水费等三项费用占总二氧化碳排放量的60%至70%。对于一人家庭，结果表明，“交通和通讯”项目的二氧化碳排放量最大，但存在性别和年龄段的差异。年轻群体中男性家庭在“交通和通讯”项目中的排放比例较高。另一方面，女性家庭表现出了差异。老年组的CO_2排放量大于青年组，主要来自燃料、光、水三项。分析结果表明，重新审视燃料、光、水费的使用将是减少家庭层面的CO_2排放，实现社会可持续发展的关键因素。

This research clarifies the relationship between household expenditures and CO_2 emission using the data of "CO_2 Emission Point Table" and the raw data of "National Survey of Family Income and Expenditure 1984".The frequency distributions of household expenditures and of CO_2 emission were drawn by different types of family, couples, couples with one child, couples with two children, and couples with three children. The result shows that CO_2 emission for couple is 1277kg and one child emits 188kg of CO_2. However, other child shows 66kg. Three items such as Transportation and communication, Foods, Fuel, light and water charges share 60 to 70 percent of total CO_2 emission. As for one person household, the result shows that CO_2 emission from the items of "transportation and communication" is the largest, however it differs in sex and age groups. Male households in younger group emit large proportion in the items of "transportation and communication". On the other hand, female households show the differences. CO_2 emission in older group is larger than younger group and it mainly comes from the items of "fuel, light and water".The findings of analysis shows that reexamining the usage of Fuel, light and water charges will be the key factor in order to reduce CO_2 emission in household level to achieve sustainable society.
