States Want Cap-and-Trade Added to U.S. Carbon Rules

U.S. states with cap-and-trade laws want the Obama administration to add their carbon markets into new federal greenhouse-gas regulations, a California environmental official said.

State-run carbon-trading programs should be “treated as equivalents or substitutes” for Environmental Protection Agency regulations for emissions tied to global warming from power plants, oil refineries and factories, Mary Nichols, chairman of the California Air Resources Board, said yesterday in a telephone interview.
