Abstract
Many pro-environmental behaviors for reducing CO2 emission are recommended recently, thus people might choose to behave in some ways. A perceived effectiveness, which is said to influence the behavioral choise, might differ from actual effectiveness. This is because this factor is affected by various cognitive bias. We therefore supposed the hypothesis that providing information of actual effectiveness would lead to decrease the difference between perceived and actual effectiveness, and then this difference would make pro-enviromental behaviors more efficient. The reduce of difference by providing information is supported by the data analysis of this experiment.
