The growing field of political education through environmental issues is organized around processes, which reach beyond the formal ones found in academic disciplines and national curricula into informal processes (such as social mobilization) and nonformal processes (such as those found in various international educational recommendations). Using theoretical approaches from the fields of political philosophy and the social sciences, this book develops a simultaneously conceptual and analytical framework for the political in educational content involving environmental issues. This framework is then used to empirically analyze educational content on sustainable development formulated by UNESCO, as well as the Tunisian curriculum. The theoretical and empirical studies carried out in this book lead to proposed curriculum tags for political education through environmental issues, with the intent of opening this field to inclusion in the didactics of curriculum research.
