English as foreign language (EFL) curricula commonly include certain sustainable development (SD) topics, which are covered in a limited fashion within a larger topic base. Because SD is a global issue and participation in that conversation occurs primarily in the English language, students in the EFL classroom are in a prime position to benefit from an increased exposure to an SD lexicon and SD topics. While traditional education for sustainable development (ESD) focuses on student awareness of issues and behaviors, psychology practitioners suggest that additional gains in student attitudes may be achieved by focusing on the ontology of humans and their relationships to Nature. Accordingly, this study examines ways of introducing inner work and intersubjectivity into the EFL classroom with the goal of examining and altering the viewpoint of students such that they see themselves more of Nature rather than apart from it. Examples of classroom modifications are given, including content and text recommendations, as well as course structure. Justifications are presented for including mindfulness and intersubjectivity in exercises in the EFL classroom as a method to practice ESD.
