The purpose of this article is to propose a tentative model of environment-conscious behavior, to review relevant researches on energy and water conservation, recycling, and detergents-using behavior on the basis of our model, and to clarify determinants of these behaviors. The decision making of environment-consicious behavior is hypothesized to consist of two phases. The first phase is to decide on a general goal intention of a pro-environmental lifestyle. The second is to decide on a specific behavior intention of environment-conscious behavior consistent with the general goal intention previously determined. The main conclusions of this review are as follows. The facilitating factors of the goal intention were the three main beliefs about the environmental problems; the perceived seriousness of environmental problems, the ascription of responsibility for environmental problems, and the belief in the effectiveness of an proenvironmental lifestyle. The main inhibiting or facilitating factors of the behavior intention were the three evaluations of this behavior; the feasibility evaluation, the costbenefit evaluation, and its social norm evaluation.
