Our research offers a number of contributions. On the theoretical level, two main contributions are worth mentioning. First, this study brings new insights into understanding the impact of interpersonal influence on the adoption of eco-friendly behavior. Even though the social facet of pro-environmental behaviors has received increasing attention lately, the largest part of the literature remains exclusively focused on individual predispositions. Little is known about the mechanisms through which social norms affect ecological decisions. The main contribution of our

Our findings show that environmental concern ascribed to relevant others influences individual behavior through the mediation of perceived social risk and self-incongruity associated with the environmentally harmful product. These two concepts were not addressed in prior research on pro-environmental behavior, but provide interesting results. Moreover, even though the literature on perceived risk is extensive, the social dimension of the construct is often neglected.
