President-elect Joe Biden announced the United States would rejoin the Paris Climate Agreement (PCA) on the first day he enters office.
What is the PCA and why is it important?
The PCA, signed in 2015 by 189 countries, aims to curb greenhouse gas emissions, thereby keeping global average temperatures from rising more than 3.6 degrees Fahrenheit. These actions would forestall rising sea levels and higher frequencies of tropical storms, floods, and droughts.
Each PCA signatory set voluntary targets for reducing greenhouse gas (GHG) emissions. Since terms of the climate agreement are voluntary, they do not carry the force of law. The only binding requirement is accurate reporting by signatories on their GHG reduction efforts.

What are the consequences of the U.S. rejoining the PCA after announcing intentions to exit in 2017?
Some PCA signatories will likely doubt the intentions of the U.S. However, upon re-entering the PCA, President-elect Biden has committed to use “every tool of American foreign policy to push the rest of the world to raise their ambitions alongside the United States.” To achieve that objective, a Special Presidential Envoy for Climate will focus on international issues while a White House climate director will manage domestic policy issues.
Which countries have filled the international climate leadership vacuum since the U.S. took a lower profile in PCA activities?
- China announced during the 2020 United Nations General Assembly their intentions to be carbon-neutral (i.e., net zero greenhouse gas emissions) by 2060.
- The European Union, the de facto PCA leader during the United States’ absence, adopted a European Green Deal program to achieve carbon-neutral status by 2050.
