Analysis of garbage volume and the amount of CO₂ emission based on the consumption expenditures of households considering fuzzy group

Abstract

In this study, the total volume of garbage per year is estimated by the possibilistic regression analysis using the consumption expenditures of households as the independent variables. At the same time, the fuzzy quantification theory I is used to estimate which expenditures affect the total volume of CO₂ emissions due to garbage. In Nagano city, the garbage collection system have changed over the years. Therefore, numeric value between 0 and 1 were assigned to the garbage collection systems and used as the fuzzy measure. The fuzzy partial correlation coefficients between the total amount of CO₂ emissions and expenditures show that the groups of goods such as vegetables or confectioneries affect the amount of CO₂ emissions, while household goods such as furniture do not have much of an effect.
