The Paris Agreement strengthens the global climate effort by requiring all countries to set climate goals and by establishing new mechanisms to hold countries accountable and to build ambition over time.

The agreement was reached in December 2015 and entered into force 11 months later.  In June 2017, President Trump announced that the United States would withdraw from the agreement.
