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. It covers climate change mitigation, adaptation, and finance. The Agreement was negotiated by 196 parties at the 2015 United Nations Climate Change Conference near Paris, France.

The Paris Agreement was opened for signature on 22 April 2016 (Earth Day) 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.

As of July 2021, 191 members of the United Nations Framework Convention on Climate Change (UNFCCC) are parties to the agreement. Of the six UNFCCC member states which have not ratified the agreement, the only major emitters are Iran, Turkey, and Iraq (though the president has approved that country's accession). The United States withdrew from the Agreement in 2020, but rejoined in 2021.
