Emerging issues related to climate change have been explored in recent years as the need for appropriate behavioral solutions grows. However, one of the main problems raised and yet to be solved is the challenge to encourage people to act against climate change. One of the identified barriers is the mental indirect link between the influence of human activities in the present and their future consequences. This psychological distance could be investigated by examining temporal discounting—the overvaluation of benefits in the present compared to benefits in the future—and its relationship to environmental behavior on consumers’ attitudes toward green purchasing. In this research, we conducted a survey (n = 337) to examine the relationship between temporal discounting and perceived seriousness of environmental behavior and investigated the moderating effect of consumers’ attitudes regarding green purchasing. The results show a moderating effect of these consumers’ attitudes on the relationship between temporal discounting and perceived seriousness of environmental behavior. These findings make important contributions to environmental policies by rethinking and adapting new solutions that promote behavioral change, namely by exploring psychological variables and identifying green consumption profiles.
