Abstract
Recently, The garbage problem has become aggravated. This Problem includes that the capacity of waste treatment plants is not only insufficient, but also the global warming is caused by carbon dioxide emission. This research investigates the garbage volume and CO2 emission reduction in Nagano city using households survey data. A life cycle inventory analysis is employed to represent the relation between the CO2 emission and household expenditures. At the same time, the forecasting model of the garbage volume is also estimated by using a possibilistic regression model. And using these models, as restrains on CO2 emission, the garbage volume is estimated.
