Elon Musk, the CEO of Tesla and SpaceX, has announced his resignation from Donald Trump's business advisory council following the president's decision to pull the U.S. out of the Paris Agreement on climate change.
Musk made the announcement on Twitter after warning May 31 that he had done all he could to persuade the White House to stay in, CNN Money reported.
Renewable energies are a key part of Tesla's brand.
"Am departing presidential councils. Climate change is real. Leaving Paris is not good for America or the world," Musk wrote on Twitter, according to CNN.
Musk had previously come under pressure to exit the council, particularly in January, when Trump issued an executive order banning travel to the U.S. from seven Muslim-majority countries. Musk said at the time he disagreed with the policy.
"Advisory councils simply provide advice, and attending does not mean that I agree with actions by the administration," Musk explained in a statement.
In May, Tesla began accepting deposits for its new solar roof in an effort to further develop renewable energy sources.
"That's the vision for the future we think is the only sensible vision for the future -- and the one we're building towards," Musk said at the time.
Musk is not the only business leader who has spoken out against Trump's decision.
Microsoft President Brad Smith stated his company was "disappointed" by the withdrawal.
"Disappointed with today's decision on the Paris Agreement. Climate change is real. Industry must now lead and not depend on government," wrote Jeff Immelt, CEO of General electric, according to Fortune.
IBM took a similar view, declaring in a statement that it will "reduce its own greenhouse gas emissions and will continue to help our clients do so as well."
Statements from Amazon, HP and Intel noted the companies' support for the Paris Agreement and added that climate change was a real issue.
On the other hand, Trump received support from his decision from Republican allies.
"The Paris climate agreement was simply a raw deal for America. Signed by President Obama without Senate ratification, it would have driven up the cost of energy, hitting middle-class and low-income Americans the hardest. In order to unleash the power of the American economy, our government must encourage production of American energy. I commend President Trump for fulfilling his commitment to the American people and withdrawing from this bad deal," House Speaker Paul Ryan said, according to CBS News.
Department of Energy Secretary Rick Perry and Senate Majority Leader Mitch McConnell also praised the move.
