The Paris Agreement (French: l’accord de Paris) is an agreement within the United Nations Framework Convention on Climate Change (UNFCCC), on climate change mitigation, adaptation, and finance, signed in 2016. The agreement’s language was negotiated by representatives of 196 state parties at the 21st Conference of the Parties of the UNFCCC in Le Bourget, near Paris, France, and adopted by consensus on 12 December 2015. As of March 2021, 191 members of the UNFCCC are parties to the agreement. Of the six UNFCCC member states which have not ratified the agreement, the only major emitters are Iran, Iraq and Turkey, though Iraq’s president has approved that country’s accession. The United States withdrew from the agreement in 2020 under the leadership of Donald Trump, but rejoined in 2021 after Joe Biden became President.
Biden made the pledge, called the “nationally determined contribution,” while speaking at a two-day virtual climate summit attended by dozens of world leaders Thursday morning. Biden rejoined the 2015 climate pact in February, reversing a decision by President Donald Trump to withdraw the U.S. from the global coalition to curb carbon emissions.
