This article aims to empirically test the so called low-cost hypothesis. The hypothesis posits that cost moderates the strength of the relationship between environmental concern and behavior. The effects of the behavioral cost and environmental concern on household waste recycling were evaluated, using empirical data collected from 2,695 respondents in Cologne, Germany. Empirically, a clear effect of both behavioral cost and environmental concern can be identified. Recycling rates are higher when a curbside scheme is implemented or the distance to collection containers is low. In addition, the probability of recycling participation rises when the actor has a pronounced environmental concern. This effect of environmental attitudes does not vary with behavioral cost and opportunities. Therefore, the low-cost hypothesis is not supported by the study.
