Nature deteriorations like climate change, biodiversity loss, and energy crises, pose threats to the equilibrium of our planetary ecosystem, demanding coordinated efforts across sectors and disciplines. English Language Teaching (ELT) shares the responsibility and potential to address these environmental challenges. However, environmental initiatives in ELT are limited and lack a unified term, concept, and framework to guide practitioners and researchers systematically. This article provides overview of Eco-ELT as a pathway for environmental research and practice in ELT. It delves into the term, concept, key points, and instances of pedagogical practices teaching environmental issues in ELT. Let’s collectively address environmental destructions through Eco-ELT. It is never too late for our beloved field of ELT to contribute to the preservation of our planetary ecosystem.
