But the program for the event, obtained by The New York Times and verified by the Competitive Enterprise Institute, also included major corporations, like Google and Amazon, that have made their commitment to addressing climate change a key part of their corporate public relations strategies.

Those companies both signed a pledge of support for the Paris Agreement and joined a coalition that vowed to stick to the climate pact’s goals after President Trump announced the United States would withdraw from it.

A Google representative said the tech giant’s support of the gala did not necessarily mean it supports climate denial. “We’ve been extremely clear that Google’s sponsorship doesn’t mean that we endorse that organization’s entire agenda,” said a spokesman for the tech giant, whose manager for outreach was listed on the dinner’s host committee.

A spokeswoman for Amazon, where employees have been urging the company’s chief executive, Jeff Bezos, to adopt a climate change policy, said the company “may not agree with all of the positions of each organization,” but believed that its $15,000 contribution to the event “will help advance policy objectives aligned with our interests.”

Analysts at C.E.I. do advocate on a wide range of policies, including opposing antitrust laws, an issue dear to tech and telecom giants as well as other major corporations.
