The purpose of this study is to evaluate the carbon point system from consumers’ point of view, and contribute to proposing ways to establish the carbon point system as a sustainable system by discussing what needs to be improved. It analyzed the differences between carbon point system participants and non-participants in terms of eco-awareness and environment actions, participants’ satisfaction with and use of the carbon point system, and the characteristics of non-participants. This study also tried to understand how eco-awareness, environment actions, and consumers’ awareness of the carbon point system affected participation in the carbon point system. The results showed that there was no significant difference between participants and non-participants in terms of eco-awareness and environment actions except for the greater importance of environmental conservation than economic development, and self-assessment of the level of eco-awareness. It was revealed that participants were more aware of the carbon point system, but the level did not meet expectations. As for satisfaction with the operation of the system, consumers living in larger homes were more satisfied. It turned out that non-participants were not well aware of the carbon point system, and they said that PR and educational programs would need to be invigorated in order to raise the participation ratio. Lastly, the more aware of the carbon point system they are, the more likely they are to participate in the carbon point system.
