Abstract
This article examines the dynamics of the climate movement’s (CM) engagement within global civil society (GCS), focusing on how this relates to its evolving commitment to anti-colonial climate politics and the wider, ongoing tensions between actors from the Global North and South within the movement. Here, this article contributes with a theorization on how counter-hegemonic and anti-colonial social movement alliances can be forged in GCS, building from neo-Gramscian, post- and decolonial concepts. This theorization builds on a study of the COP26 Coalition’s efforts in Glasgow in November 2021, exploring how the coalition strategically utilized post-apocalyptic environmentalism to amplify Southern and anti-colonial perspectives within the broader CM and to carve out a space for such perspectives within GCS. However, this study also highlights how GCS spaces are shaped by a neo-colonial global hegemony which fosters structures of Northern epistemic dominance which often function to de-legitimize, exclude, or co-opt non-Western knowledges and movements within GCS.
