The Global South is disproportionately affected by climate change, but digital societies are structured so that the global governance of artificial intelligence (AI) spawn's new climate adaptation infrastructures, which place two major threats to digital sovereignty and epistemic justice in marginalised territories. The chapter examines the ways in which BRICS+ countries (comprising 45 -percent of the worldwide population) are using AI to become more climate-resistant and challenging Western technology governance paradigms by invoking data sovereignty and implementing Indigenous Knowledge Systems (IKS).We apply the doctrinal policy analysis in the outreach of the decolonial theory and the digital sovereignty perspective through a comparative case-study analysis of the four main BRICS + initiatives that relate to India, Brazil, South Africa, and China along with the additional boundary cases based on Ethiopia and Iran.
