When it comes to setting emissions standards California has long led the world. And California’s market is too big and too important: No car company can afford to ignore the standards set in the sixth largest economy in the world. Despite a new administration in Washington determined to relax the emission challenges for the car industry, California’s clean-air agency has voted to push ahead with stricter emissions standards for cars and trucks. The standards would require automakers to nearly double the fuel economy of new cars and trucks by 2025. Twelve other states will follow, meaning a coalition that covers more than a third of the vehicle market in the U.S. will be enforcing the new standards.
