India formally ratifies Paris climate change deal
India on Sunday deposited the 'Instrument of Ratification' at the UN to formally ratify the landmark Paris climate change deal. PM Narendra Modi had earlier announced that India, responsible for 4.1% of global greenhouse gas emissions, will ratify the agreement on Gandhi Jayanti. The deal will take effect when at least 55 countries, accounting for 55% emissions ratify the pact.
