Hundreds of American companies, including Mars, Nike, Levi Strauss and Starbucks, have urged President-elect Donald J. Trump not to abandon the Paris climate deal, saying a failure by the United States to build a clean economy endangers American prosperity.

In a plea addressed to Mr. Trump — as well as President Obama and members of Congress — 365 companies and major investors emphasized their “deep commitment to addressing climate change,” and demanded that he leave in place low-emissions policies in the United States.

“Failure to build a low-carbon economy puts American prosperity at risk,” the companies said in a joint letter announced on Wednesday in Marrakesh, Morocco, where global leaders are determining the next steps for the Paris deal. “But the right action now will create jobs and boost U.S. competitiveness.”
