Trump said during the campaign he would “cancel” the Paris agreement to make global reductions in carbon emissions that Obama signed in December.
The agreement was not a treaty and was not approved by the Republican-controlled Senate, and legal experts agree that as president Trump would have the authority to walk away. Even without a formal withdrawal, Trump could simply order EPA not to take any action toward meeting the U.S. commitments to reduce greenhouse gas emissions by at least 26 percent below 2005 levels within the next 10 years.
