The BASIC countries, comprising Brazil, South Africa, India, and China, play a pivotal role in shaping international climate policy due to their unique positions as emerging economies with substantial greenhouse gas emissions and large populations dependent on vulnerable ecosystems. Their influence is particularly significant in the context of global environmental negotiations, such as the United Nations Framework Convention on Climate Change (UNFCCC), the Kyoto Protocol, and the Paris Agreement, as they represent both developmental priorities and environmental responsibilities. Brazil, with its vast Amazon rainforest, is crucial in discussions on carbon sequestration, deforestation, and biodiversity conservation. The Amazon acts as a global carbon sink, absorbing significant amounts of carbon dioxide, and any changes in Brazil’s land-use policies have far-reaching implications for climate mitigation. Brazil has historically used its natural resources strategically in climate negotiations, emphasizing the principle of “common but differentiated responsibilities” to assert that developed countries should bear greater responsibility for historical emissions while supporting developing nations with technology transfer and financing. Policies such as the National Policy on Climate Change and efforts to reduce deforestation in the Amazon have positioned Brazil as both a defender of developing countries’ rights and a contributor to global mitigation strategies. However, fluctuations in deforestation rates due to political changes demonstrate the challenges in balancing economic development, particularly from agriculture and mining, with global climate commitments. India, as the world’s third-largest emitter, has highlighted the importance of equity in climate agreements. Its climate policy approach emphasizes sustainable development, energy access, and poverty alleviation, arguing that ambitious climate actions must be aligned with development priorities. India has been a vocal advocate for the principle of differentiated responsibilities, insisting that
