The current study explored the determinants of individual and collective pro-environmental behaviors in Germany and Japan. A self report questionnaire was sent to two random sample respondents by mail in Cologne, Germany (N=996) and Nagoya, Japan (N=531). Hierarchical regression analyses demonstrated an interaction between country of respondent and both individual and collective behaviors. For individual behavior, subjective norms played an important role in Japan where interpersonal relationship is emphasized, whereas perceived behavioral control played an important role in Germany. Social factors, such as the amount of network and subjective norms, affected collective pro-environmental behaviors in both samples. The results highlighted the importance of social factors in studies of collective pro-environmental behaviors.
