United States Again Abandons the Paris Climate Agreement

On his first day in office, Trump ordered a second U.S. withdrawal from the Paris climate agreement and directed federal agencies to end or revoke related international climate commitments.

The withdrawal reversed the U.S. return to the Paris framework that had occurred earlier in the decade and reduced federal participation in coordinated global emissions-reduction policy. As with Trump's first-term withdrawal, the move affected U.S. standing in international climate negotiations and reduced binding federal commitments to emissions targets, though it did not by itself alter individual state or private-sector climate initiatives.

The withdrawal order took effect as a day-one action; available sourcing does not indicate a legal challenge to the withdrawal itself.
