Withstanding pressure from automakers, air quality officials in California voted 9-0 yesterday to move forward with a mandate requiring that 3 million electric and low-polluting vehicles be sold in the state over the next decade. The vote by the California Air Resources Board automatically triggers similar mandates in Vermont, Massachusetts, and New York, and affects six of the largest auto manufacturers — DaimlerChrysler, Ford, General Motors, Honda, Nissan, and Toyoto. The mandate is far less progressive than what was originally proposed 10 years ago, requiring more low-polluting vehicles on balance and fewer zero-emissions vehicles. Still, enviros were pretty dang pleased with yesterday’s outcome.
