The COP 21, held in Paris from November 30 to December 12, 2015, gathered representatives from 196 countries aiming for a universal agreement to combat climate change, focusing on limiting global temperature rise and enhancing climate action. Key provisions of the agreement include differentiation between developed and developing countries, binding commitments for nationally determined contributions, and ensuring support for adaptation and mitigation in developing nations. Indian contributions include ambitious targets for renewable energy, sustainable practices, and climate finance, with varying opinions from environmentalists and global leaders about the agreement's effectiveness and its implications for climate justice.
