The risk of neutralizing the political dimension in environmental education through the depoliticization of its thematic objects, its intended learning, and its educational purposes, is a curricular phenomenon identified by recent research in the field. The aim of this article is to develop a conceptual and analytical framework to identify clarification of the political dimension. The framework on the political dimension as part of environmental education provides political learning entry that help to avoid the vanishing of this dimension. Nevertheless, this is not without themes and cannot be decoupled from its educational aims. Therefore, establishing a conceptual and analytical framework considering environmental themes, political learning and educational purposes together can effectively support the curricular construction of environmental education's political dimension. Thus, we define six environmental issue meta-themes by politicization and depoliticization trends that cross them; draw on environmental and political education research to identify political learning components in an environmental education context; and discuss linking political learning to possible educational purposes. We believe that within the dialectic of politicization/depoliticization that crosses the thematic subjects, learning and purposes of environmental education's political dimension, the path leading to the democratic subjectification of learners guarantees its non-neutralization.
