The California Air Resources Board at press time was preparing to adopt sweeping new automotive emissions standards aimed at reducing both greenhouse gases and smog-forming pollution produced by cars beginning in 2016. After the standards are fully phased in by 2025, the Air Board estimates that California would have 1.4 million electric vehicles on the road, including both pure battery-powered models and plug-in hybrids that run on electricity for commuting and around town use, but have onboard gasoline engines for longer trips. Air Board chair Mary Nichols noted that the standards are not opposed by the auto industry.The Air Board standards not only call for electric cars, but also gasoline models that get progressively better mileage in order to reduce greenhouse gas emissions. By 2025 under the standards, the average new car is expected to get 54.5 miles per gallon. The California requirements are closely aligned with federal auto rules that President Obama is backing.
