The climate crisis, with its global reach, demands diverse solutions, yet many religious education curricula, for example in Swedish schools, lack climate-focused content. Given that climate change disproportionately affects different regions, a postcolonial perspective is crucial in understanding the disparity between the crisis’s causers and victims. Religions contribute diverse ethical frameworks and spiritual resources, providing both identity and hope in the face of ecological anxiety. By integrating climate concerns into religious education, students can engage with concepts such as eco-theology, climate justice, and the spiritual responsibilities of humans toward nature. This integration fosters critical discussions on the socio-political roles of global religious institutions, such as the World Council of Churches can serve as platforms for dialogue and cooperation. The paper will also discuss the collaborative development of educational materials, highlighting the importance of cooperative work between educators, theologians, and interfaith groups. By drawing on examples from various religious traditions, the paper emphasises the potential of religious education to offer constructive, globally unified responses to the climate crisis while respecting the plurality of religious experiences.
