Soon after President Trump announced that the United States would back out of the Paris climate accord, several large companies based in the United States that had supported the international pact said they were disappointed by the decision and would continue their environmental efforts.
And two chief executives who sat on Mr. Trump’s economic advisory council — Elon Musk and Robert A. Iger — said they were leaving that group because they disagreed with the exit from the Paris agreement.
While Mr. Trump said the decision to exit the deal was made to protect American jobs — a contention that environmental groups have disputed — some large companies had urged the president to stay in the accord.
Twenty-five companies, including Apple, Facebook, Google and Microsoft, bought full-page ads in The New York Times, The Wall Street Journal and The New York Post last month to argue their case. Some of those companies, and others with similar views in the technology, energy and engineering sectors, reacted quickly on Thursday.
But so did some companies, particularly in the coal industry, that supported Mr. Trump’s decision.
