Just before ending the five-hour long investigation into the U.S Environmental Protection Agency’s waiver denial, Senator Barbara Boxer (D-CA) announced she was introducing a bill to avert similar EPA waiver disapprovals. The legislation directs the EPA administrator to grant California’s request for the waiver and allow the state to implement its greenhouse gas emissions standards for vehicles. It also permits other states to adopt California’s emissions standards. “I will use every available tool to ensure that California and the nation are able to reduce the pollution that causes global warming,” Boxer said January 24. “One of those tools is legislation that essentially overturns Mr. Johnson’s actions.” Boxer introduced similar legislation last year, but it never got off the ground. Cosponsors of this week’s bill include Senator Dianne Feinstein (D-CA), 12 other Democratic senators, as well as Senators Joe Lieberman (I-CT) and Susan Collins (R-ME).
