The purpose of this study is to investigate whether the resident-based carbon dioxide emissions trading system is realizable. We conducted a survey in the vicinity of the Minamisenrioka area in Settsu City of Osaka Prefecture in January, 2009. The survey results indicate that although the residents in the Minamisenrioka area show considerable concern toward environmental issues, they still know little about the carbon dioxide emissions trading system. In addition, many residents consider that government should take the lead in combating global warming. Meanwhile, the results also suggest that the residents wish for an emissions trading system that will not influence their current lifestyle much. Finally, by examining the factors influencing the residents' approval of the emissions trading system, it is clear that if various efforts (e.g., diffusing knowledge on bad effects caused by global warming, promoting clinical diagnosis for households' energy-saving scheme, conducting enlightenment activities regarding the fact that the emissions trading system contributes greatly to the reduction of carbon dioxide emissions, etc.) are made, the possibility that residents will support the designed resident-based carbon dioxide emissions trading system in the Minamisenrioka area will increase.
