“Strong clean energy and climate policies, like the Clean Power Plan, can make renewable energy supplies more robust and address the serious threat of climate change,” they said.

That action also spurred Mr. Immelt to write a blog post to G.E.’s 300,000 employees in which he criticized the rollback.

“We believe climate change is real and the science is well accepted,” said the post, first reported by Politico. “This is just the beginning of what will be a long process” of a repeal, he said, but “no matter how it unfolds, it doesn’t change what G.E. believes.”

Jennifer Friedman, a General Electric spokeswoman, declined to say whether Mr. Immelt intended to relay his thoughts to Mr. Trump personally. Many other companies also declined to commit their executives to intervening with the president on climate-related policies.

But Ms. Friedman emphasized that Mr. Immelt was outspoken, and she cited G.E.’s focus on clean energy, including Current, a subsidiary that focuses on products and services in energy efficiency, renewable generation and energy storage to large customers.

“He’s pretty out there and clear,” she said. “That’s his position in every conversation he has.”

A PepsiCo spokesman, Jay Cooney, said the company believes that “combating climate change is critical to the future of our company, customers, consumers and our world.” Kevin Gardner of Walmart, said its environmental commitments were “embedded in our business.”

Thomas Hushen, spokesman for Campbell Soup, said the company supported “continued U.S. participation in the Paris agreement and the continuation of low-carbon policies and investment in a low-carbon economy.” Campbell’s chief executive, Denise Morrison, participates in Mr. Trump’s advisory council because “we believe it is important to have a voice on matters that will affect our industry, our company and our employees.” Mr. Hushen said.
