Paris Climate Agreement

The Environmental Policy Initiative is tracking the environmental regulatory rollbacks of the Trump administration. Click here for the list of rules we are following

Why it Matters

The U.S. is the second largest greenhouse gas emitter in the world, and the largest historical emitter. America’s approval of the Paris Climate Agreement signaled our intention to cooperate globally in reducing our emissions and helping others reduce theirs. Withdrawing would undermine our credibility as a leader in climate change science and action, and jeopardize the emissions reductions commitment that we made under the Paris Agreement.

Current Status

President Trump has announced his intention to withdraw, but the U.S. remains a party. Under the terms of the agreement, the U.S. cannot formally announce its intention to withdraw until November 4, 2019; withdrawal would then take place after one year, or on November 4, 2020.


On April 22, 2016 the United States signed the Paris Climate Agreement treaty, and committed to reducing domestic greenhouse gas emissions by 26%-28%, compared with 2005 levels.

On November 4, 2016 the Paris Climate Agreement on greenhouse gas emissions mitigation, adaptation, and finance entered into force, requiring each member country to submit a plan for addressing climate change.

Trump Era

On June 1, 2017 President Trump announced the United States will withdraw from the Paris Climate Agreement.
