At the recent summit in Rio de Janeiro, leaders of the BRICS group signaled their intention to take the lead on climate justice, positioning themselves as champions for the Global South amid waning Western leadership. The summit's declaration emphasized climate finance, conservation, and systemic reform, but highlighted the need for concrete action, including fossil fuel phaseout timelines and transparent oversight mechanisms. BRICS has evolved from an economic bloc to a powerful political force, now driving global green growth through clean energy investments and South-South cooperation in sectors like solar technology and electric vehicles. India, as the incoming chair, is pivotal in shaping multilateral climate platforms and fostering collaboration among developing nations. The upcoming COP30 summit will test BRICS' resolve to align ambition with action, demanding equity-driven finance, transparency, and a unified approach to climate governance that could redefine the global order.
