ABSTRACT
This chapter discusses concepts of sustainability, socially critical action, and social justice in relation to environmental literacy, which is one of the central foundations of global citizenship. In that respect, the emphasis is placed on the maxim: Think globally, act locally! Within this chapter, I emphasize the importance of the active participation of institutions, social groups, and individuals in these processes. I also draw attention to the importance of environmental ethics, starting from the hypothesis that environmental literacy is deeply related to the qualitative development of the identity of the learner and that adult education can play a very important role in developing environmental literacy.
