Those executives were Elon Musk, CEO of electric-car maker Tesla ( tsla ) , who said that “Leaving Paris is not good for America or the world;” and Disney CEO Robert Iger, who said he would resign as “a matter of principle.”

Trump created the group, called the President's Strategic and Policy Forum, shortly after being elected so he could get advice from the business world about creating jobs and lifting the economy. The executives are trying to capitalize on Trump’s "America first" ideology by warning that a withdrawal would put the U.S. at a disadvantage in a global race to develop and deploy clean-energy technology, potentially ceding that market opportunity to China, the world’s top emitter of greenhouse gas emissions.
