California plans to sell its first carbon allowances in November, undeterred by warnings from a federal energy commissioner that a system meant to curb emissions may harm businesses, the state air board’s head said. The agency is on schedule to develop a platform for a Nov. 14 auction of allowances, which will be used by companies to comply with emissions limits beginning next year, Chairman Mary Nichols said today in an interview in San Francisco. She is scheduled to speak with Philip Moeller, one of five members of the Federal Energy Regulatory Commission, later today. California carbon futures have dropped 12 percent from this year’s high on speculation that the auction may be delayed after Moeller warned California Governor Edmund G. Brown Jr. on Aug. 6 that the system may “seriously impact” the U.S. West Coast economy. Moeller flagged a provision that prohibits companies from sending carbon-intensive power outside the state.
