The purpose of this study is to investigate the green consumption behaviors, the current patterns of the green information diffusion process and the relationships among the variables in a community-based setting within Taipei City. It also aims to assess the information process and the effective media approach for the reference of further media formation design and intervention programs. Wan-Hao is a small-sized, urban area community which is fitted the research criteria and therefore was selected for the study. A structure-ended questionnaire was designed to collect the quantitative data. The sample consists with 279 community members. Also an open-ended questionnaire was designed as an instrument for data collection of focus groups' in-depth interviews with three different community groups (mothers, old people, and community leaders). Major results are as follows: Recycling behavior is the best performance of the green consumption behavior among the community members. The other three parts of green consumption are reduce, refuse, and reuse behaviors in order. General speaking, the value system among community members prefer more environmentally protective value than economic developing value. The main barrier for green consumption behavior is lack of incentive policy for buying green products. The level of perceived barriers and benefits, the level of perceived value, age, and the supportive level of the referent group could effectively predict the green consumption behavior; and the explanation power of all these four variables is 16.6%. The effective ways for the community media information process are the formal notes from the head of the subdivision district and the DM sent from community center. The experts or someone with friendly outlook are the best media representatives, the double-sides information presentation is the better structure of media than just report one-side of the issue. Easy to understand, real photo picture, and the issues related to real life experience and personal health are important points of the format for the printed-media design.
