Why it Matters
The United States is the second largest greenhouse gas emitter in the world and the largest historical emitter. America’s approval of the Paris Climate Agreement in 2016 signaled our intention to cooperate globally in reducing our emissions and helping others reduce theirs. Currently, 196 nations have formally adopted the agreement. Under the Trump administration, the US withdrew from the Paris Agreement on Nov. 4, 2020. However, the Biden Administration rejoined on February 19, 2021, and the US has committed to achieving a 50 to 52 percent greenhouse gas emissions reduction from 2005 levels by 2030.
On inauguration day Jan. 20, 2021, President Biden formally accepted the Agreement, initiating the process to rejoin the Paris Agreement on Feb. 19, 2021 and ensuing conference of parties—COP26, which is scheduled for Oct. 31, 2021 through November 12, 2021.
