Tesla CEO Elon Musk is making good on his threat and will be parting ways with President Trump's advisory councils moments after Trump announced the U.S. would break with the Paris climate agreement.

"Am departing presidential councils. Climate change is real. Leaving Paris is not good for America or the world," the billionaire electronic car magnate said in a tweet Thursday afternoon.

A day earlier, responding to reports that Trump was going to go through with leaving the international accord to reduce global greenhouse gas emissions, Musk said he would have "no choice" but to depart the President's Strategic and Policy Forum, comprised of some of America's leading business leaders to advise Trump and help him put together his economic agenda, as well as Trump's manufacturing jobs initiative.

Musk previously resisted criticism for his participation in the councils, saying he would bring a progressive view to the table.

Speaking to Fox News from the Rose Garden of the White House following Trump's announcement, Commerce Secretary Wilbur Ross downplayed the loss.

"There are no end of businessmen who wanted to be on that council," he said. "I don't think that there will the slightest problem replacing them, not that we won't miss their participation."
