The U.S.'s top corporate executives agree on the need for energy and climate-change policies, but consider Congress' attempts at legislation to be largely piecemeal approaches to comprehensive issues, Exxon Mobil Corp. (XOM) Chairman and Chief Executive Rex Tillerson said Thursday.

In comments to reporters at a Business Council meeting in North Carolina, Tillerson dismissed notions that U.S. companies are at odds with each other over whether such government policies are necessary.

"I don't think there is a split over the need to do something," said Tillerson before ducking into meetings with dozens of fellow chief executives. "In discussion among ourselves, people are focused on serious challenges and serious solutions."

Much of the corporate push-back on legislative proposals dealing with energy conservation, carbon-emissions reductions and alternative energy, he said, stem from the limited focus of the proposals. He said the measures often fail to address the broader implications regulations to business competitiveness and the U.S. economic performance.

"One of the challenges of dealing with Washington, and it's not unique to this administration, is they look at issues in a very narrow way," he said. "It's a long-term problem with how we formulate policy. We've never really had a sensible, long-term policy" on energy.

Tillerson said it is unlikely that Congress will be able reconcile versions of energy legislation in the House and Senate and approve a single bill by the end of the year.

Tillerson was joined at the Business Council press briefing by Jim Owens, chairman and chief executive of Caterpillar Inc. (CAT) ,and Jamie Dimon, chairman and chief executive of JPMorgan Chase & Co. (JPM).
