Paris Climate Agreement to enter into force on 4 November

New York, 5 October— The historic Paris Agreement to address climate change will enter into force on 4 November, the United Nations announced today.

“This is a momentous occasion,” said UN Secretary-General Ban Ki-moon as the latest instruments of ratification were accepted in deposit. “What once seemed unthinkable, is now unstoppable. Strong international support for the Paris Agreement entering into force is a testament to the urgency for action, and reflects the consensus of governments that robust global cooperation, grounded in national action, is essential to meet the climate challenge.”

But he cautioned that the work of implementing the agreement still lay ahead.  “Now we must move from words to deeds and put Paris into action. We need all hands on deck – every part of society must be mobilized to reduce emissions and help communities adapt to inevitable climate impacts.”

The Agreement provides that it shall enter into force 30 days after 55 countries, representing 55 percent of global emissions, have deposited their instruments of ratification, acceptance or accession with the Secretary-General.   As of today, 73 countries and the European Union have joined the Agreement, exceeding the 55 percent threshold for emissions.

The requirements for entry into force were satisfied today when Austria, Bolivia, Canada, France, Germany, Hungary, Malta, Nepal, Portugal and Slovakia, as well as the European Union, deposited their instruments of ratification with the Secretary-General.

These countries were the latest to join the Agreement this week, following New Zealand and India, and the 31 countries which joined at a special event at the UN on 21 September during the General Assembly high-level week. In early September, the world’s two largest emitters, China and the United States, joined the Agreement, providing the impetus for other countries to quickly complete their domestic ratification or approval processes.

The Agreement will now enter into force in time for the Marrakech Climate Conference (COP 22) in Morocco in November, where countries will convene the first Meeting of the Parties to the Agreement.  Countries that have not yet joined may participate as observers.

Patricia Espinosa, Executive Secretary of the UN Framework Convention on Climate Change, said, “Above all, entry into force bodes well for the urgent, accelerated implementation of climate action that is now needed to realize a better, more secure world and to support also the realization of the Sustainable Development Goals.”
