LOS ANGELES -- California regulators have approved a rule requiring 15.4 percent of new vehicles sold in the state to be electric, fuel-cell or plug-in hybrid vehicles by 2025.
The rule -- supported by major automakers -- is part of a broader package of regulations called the Advanced Clean Car program designed to cut vehicle greenhouse gas and smog-forming emissions.
The new standards could mean 1.4 million electric, fuel-cell and plug-in hybrid vehicles on California roads by 2025.
The measure also supports development of an infrastructure for hydrogen fueling stations across California, the nation's largest car and light-truck market.
General Motors, Ford Motor Co., Chrysler Group, Nissan Motor Co. and other automakers -- usually at odds with California regulators -- submitted testimony in support of the new standards.
The California Air Resources Board voted unanimously to approve the program during a two-day meeting that ended Friday, Jan. 27.
