Climate challenges constitute pivotal global imperatives, encompassing the BRICS coalition. Their mitigation necessitates multi-national collaboration owing to their inherently transboundary ramifications. Employing both analytical and comparative methodologies, this chapter provides insight into the prevailing tendencies and prospective trajectories concerning inter-BRICS cooperation. Empirical evidence demonstrates predominant emphasis on bilateral dialogues centered upon technological transfer modalities and co-financing environmentally sustainable endeavors. Notwithstanding the current prevalence of bilateral frameworks, transition toward multilateral paradigms may confer enhanced efficacy in the long-term horizon. Nationally divergent policy orientations prevail, highlighted by contrasting examples of South Africa's substantial commitment to renewable energy infrastructure vis-à-vis Russia's persistent dependence on conventional, ecologically detrimental fuel sources. Hence, we argue that achieving substantive planetary-scale outcomes mandates harmonization of objectives and uniform regulatory regimes across member states. Furthermore, we highlight that relocation of carbon-intensive industries from European and American multinational enterprises to BRICS countries engendered significant ecological repercussions. Counteractive measures currently under consideration entail targeted industrial carbon taxation mechanisms, exemplified by China contemplating an additional differential carbon levy targeting firms currently excluded from the emissions trading scheme.
