This study applied Theory of Planned Behavior and investigated the relationship among attitude, subjective norm, perceived behavioral control, behavior intention and green consumption cognition under environmental awareness. Data was collected by internet questionnaire survey. Results shown that environmental awareness has a positive significant relationship among attitude, subjective norm, perceived behavioral control and green consumption cognition. Besides, attitude, subjective norm, perceived behavioral control and green consumption cognition all have a significant relationship with behavior intention. However, there is no significant relationship between environmental awareness and behavior intention. Therefore, this study infer that attitude, subjective norm, perceived behavioral control, behavior intention and green consumption cognition play complete mediation between environmental awareness and behavior intention. Finally, this study suggests to place Carbon Reduction Label, design the exclusive mark for green B&B.
