A footnote to the Group of 20's official document summarizing the collective plan of action on climate issues states the the U.S. continues to reserve its position.
“The United States is currently in the process of reviewing many of its policies related to climate change and continues to reserve its position on this document and its content,” the footnote reads.
The document’s plan is built around the terms laid out in the Paris climate agreement.
On June 1, Trump announced that the U.S. would be pulling out of the accord.
"The United States will withdraw from the Paris Climate Accord, but begin negotiations to re-enter either the Paris Accord or really an entirely new transaction on terms that are fair to the United States," Trump said. "So we are getting out, but we are starting to negotiate and we’ll see if we can make a deal that’s fair."
He added that the nonbinding portions of the agreement would cease to be enforced by the U.S.
Trump had campaigned for the presidency on the promise to pull out of the agreement, which was one of Obama’s signature accomplishments.
