Peace lifestyles are possible in social environments that endorse peace activism. This discussion of community change processes provides an outline of mechanisms needed for successful community activism working at the cultural level. The Community Peace Cultures Program (CPCP) is an approach to building supportive environments for peace lifestyles. It is based on the normative systems culture change model for promoting change and community activism. This approach has been successfully used in areas such as litter reduction, health promotion, and other concerns in business, government, and community settings. Applied to peace activism, the program helps participants understand how their subcultures and the overall culture influence their abilities to achieve inner, interpersonal, inter-organizational, and international peace. Program participants are given an opportunity to identify what aspects of their cultures and lifestyles fail to match their personal commitments to peace. They then join with others in working towards peace lifestyle goals of their choosing. Individual action plans, and a four phase culture change process promote individually tailored peace lifestyles for families, businesses, and community organizations. (AS)
