This paper makes a twofold contribution. Firstly it presents a typology of eco-clubs that can be used to contextualise eco-club observations by researchers and can support management of eco-clubs by practitioners. Secondly it explains how participation in eco-clubs provides a space for a child to both enact and develop as a citizen, a place for being-as-becoming. It shows how children navigate adult behaviours in these settings and how these experiences afford opportunities for the development of attributes including critical and analytical thinking that are commonly associated with citizenship education in England. In conclusion the paper makes links between these unintended outcomes and the liberal underpinnings of educational institutions in England.
