"It would be good for the U.S. to stay in the climate agreement," ConocoPhillips CEO Ryan Lance told reporters as he walked offstage at the big CERAWeek industry conference in Houston.

Why it matters: The Trump administration still hasn't said what it's going to do about U.S. involvement in the 2015 Paris climate accord. ConocoPhillips joins a number of other major energy companies, including Exxon Mobil, in backing the agreement.

Lance also said Trump's policies on deregulation and infrastructure approvals will be good for the oil-and-gas industry. He warned against a border adjustment tax that could hurt retailers and said Congress needs to find the "right balance" on a tax that wouldn't benefit either side too much.
