Business leaders piled into a conference hall in central Copenhagen early on Dec. 11 to talk climate change. A lot of big hitters were there. Coca-Cola (KO) Chief Executive Muhtar Kent, Duke Energy (DUK) Chairman James Rogers, and Unilever (UN) CEO Paul Polman were just a few to lay out the role of businesses in tackling global warming. Others, including trade associations, consultants, and industry analysts, were on hand to weigh in. "Business will have to innovate, become more efficient, and create better products," says Mark Spelman, global head of strategy at consultants Accenture (ACN), who spoke at the one-day event that took place on the sidelines of the U.N.Climate Change Conference. "But that can only be based on a political framework [to stop global warming]."
