The Paris Agreement (the Paris Agreement)  is an agreement within the framework of the United Nations Framework Convention on Climate Change (UNFCCC) that deals with the reduction, adaptation and financing of greenhouse gas emissions and was signed in 2016. The language of the agreement was negotiated by representatives of 196 States Parties at the 21st UNFCCC Conference of parties held at Le Bourget, near Paris, France, and agreed on 12 December 2015.   Since February 2020, all 196 UNFCCC members have signed the agreement and 189 have left.  Of the seven countries that are not parties to the law, Iran and Turkey are the only major emitters. On October 5, 2016, when the agreement reached enough signatures to cross the threshold, U.S. President Barack Obama said, “Even if we achieve all the goals… we will only get to part of where we need to go. He also said that “this agreement will help delay or avoid some of the worst consequences of climate change.”
