The United States has delivered a notice of intent to withdraw from the Paris Agreement, an agreement by nearly 200 nations to cut greenhouse gas emissions in order to stave off the projected effects of climate change. The formal notice was delivered on November 4, the first day countries could serve such notice, and begins a yearlong process that follows more than two years after a June 2017 announcement of the nation’s intent to withdraw from the international pact. While this marks the beginning of the yearlong process, the United States will not formally exit the agreement until November 4, 2020.
Once the United States withdraws from the agreement, it will take on a reduced observer status at future Conference of the Parties gathering of the United Nations Framework Convention on Climate Change. This status will allow it to attend negotiations and comment on proceedings related to the agreement. Many state and local governments are and will remain party to subnational agreements, including the 24-state U.S. Climate Alliance, reaffirming their commitment to the standards outlined in the Paris Agreement. Michael Bloomberg, the former mayor of New York City, announced that a “U.S. Climate Action Center” will participate in future negotiations in place of the United States. However, no subnational groups will formally replace the United States within the Paris Agreement.
