Coral Davenport, reporting for the New York Times:
A new report by the environmental data company CDP has found that at least 29 companies, some with close ties to Republicans, including ExxonMobil, Walmart and American Electric Power, are incorporating a price on carbon into their long-term financial plans.
Perhaps more interesting than which companies that are on the list—it also includes Microsoft, General Electric, Walt Disney, ConAgra Foods, Wells Fargo, DuPont, Duke Energy, Google and Delta Air Lines (though unsurprisingly not Koch Industries)—is the amount they expect a ton of carbon to cost: $60. Five years ago when I interviewed Dan Kammen, director of Renewable and Appropriate Energy Laboratory at UC Berkeley, he said that to significantly reduce emissions, carbon would need to cost—you guessed it—at least $60 per ton.
