Paris Agreement
The Paris Agreement, often referred to as the Paris Accords or the Paris Climate Accords, is an international treaty on climate change. Adopted in 2015, the agreement covers climate change mitigation, adaptation, and finance. The Paris Agreement was negotiated by 196 parties at the 2015 United Nations Climate Change Conference near Paris, France. As of September 2022, 194 members of the United Nations Framework Convention on Climate Change are parties to the agreement. Of the four UNFCCC member states which have not ratified the agreement, the only major emitter is Iran. The United States withdrew from the Agreement in 2020, but rejoined in 2021. The Paris Agreement was opened for signature on 22 April 2016 at a ceremony in New York. After the European Union ratified the agreement, sufficient countries had ratified the Agreement responsible for enough of the world's greenhouse gases for the Agreement to enter into force on 4 November 2016.
