Delegates from around the world are gathering in Geneva for a critical round of negotiations aimed at securing the first global treaty to curb the mounting plastic pollution crisis.

Hours after he was sworn in to a second term, Trump pulled the U.S. out of the landmark Paris agreement to combat global warming. The United States didn’t participate in a vote in April at the International Maritime Organization that created a fee for greenhouse gases emitted by ships, or send anyone to the U.N. Ocean Conference in June.

Under President Donald Trump's leadership, the United States has withdrawn from international negotiations and commitments, particularly around climate. But the U.S. is very much involved in treaty talks for a global accord to end plastic pollution.
