Abstract
Calculating the ecological impact of different types of proenvironmental behavior has shown that having one child less is the behavior with the largest ecological impact. Despite this, environmental psychology has barely researched the childfree lifestyle as a proenvironmental behavior. The aim of this article is to explore this topic, here defined as being environmentally childfree. Twenty participants, including three couples, who have chosen to be environmentally childfree, were interviewed using semistructured interviews focusing on the psychological and social processes around making such a choice. Three main themes were identified using thematic analysis. The three main themes revolve around how the participants made the choice, how they share their choice, and how the choice is integrated into their lives. Further research should investigate being environmentally childfree as a decision made by couples, rather than as an individual decision, in addition to how the phenomenon is represented among youth and younger adults. Economic and social consequences of decreasing fertility rates should also be investigated.
