As we previously reported, two weeks ago, UN Secretary-General Ban Ki-moon announced that more than 55 countries, including the United States and China, had formally joined the Paris Climate Agreement, officially crossing one of the two thresholds required to bring the Agreement into force. The Paris Climate Agreement was adopted by the 195 Parties to the UN Framework Convention on Climate Change (UNFCCC) at a conference known as COP21 in December 2015. It will enter into force 30 days after at least 55 countries, accounting for 55% of global greenhouse gas emissions, deposit their instruments of ratification.

On Wednesday, October 5th, the UN announced that the European Union and 10 additional countries have deposited their instruments of ratification. Now, countries that have ratified the Paris Climate Agreement account for more than 55% of global greenhouse gas emissions, surpassing the second requirement for the Agreement to enter force. Thus, the Paris Climate Agreement will enter into force on November 4, 2016.

UN Secretary-General Ban Ki-moon made a statement to mark this “momentous occasion”:

“Global momentum for the Paris Agreement to enter into force in 2016 has been remarkable. What once seemed unthinkable is now unstoppable.

Strong international support for the Paris Agreement entering into force is testament to the urgency for action, and reflects the consensus of governments that robust global cooperation is essential to meet the climate challenge.”

The Paris Climate Agreement calls on countries to combat climate change and to accelerate and intensify the actions and investments needed for a sustainable low-carbon future, as well as to adapt to the increasing impacts of climate change. Specifically, governments must take actions to limit global temperature rise to well below 2 degrees Celsius, and to strive for 1.5 degrees Celsius. The Paris Climate Agreement also requires developed countries fund $100 billion in investments to assist developing countries meet the Agreement’s goals.
