The U.S. delegation to the G7 was the only country not to sign a draft joint-statement that included a commitment to follow the Paris climate agreement's provisions, according to the AP. As a result, the group didn't issue a statement at all.
Why the U.S. didn't sign: It's still reviewing its position, per the Italian development minister. Energy Secretary Rick Perry also wanted to include references to coal and fossil fuels in the statement, Reuters reports.
Context: Perry is to talk with the Italian development minister Tuesday, but Donald Trump said on the campaign trail that he didn't want the U.S. to stay in the climate pact.
