Governments and other entities worldwide are becoming increasingly aware of the need to promote sustainable living. Today, some institutions have a policy on sustainability in any field. This understanding has led to the organization of various courses and educational materials being published in all areas of education, including English language teaching (ELT). This paper examines how ELT is promoting environmental sustainability, and how ELT contributes to sustainability can be divided into three broad categories: direct, collaborative, and teacher-based. This paper also examines and analyzes the categories, as well as proposes the best way to strengthen the focus on sustainability through a variety of approaches. Collaboration between ELT teachers and teachers from other fields is not only an important way but also a concept that is often overlooked. Therefore, teacher education programs should focus on teaching the principles of sustainability, not just teaching skills, regardless of sustainability skills. English teacher education programs should support innovation for sustainability, not just English teaching methods, and finally, future studies should examine the effectiveness of this combination.
