The policy allows Californians to keep driving gas-powered vehicles and buying used ones after 2035, but no new models would be sold in the state.
One-fifth of automakers’ sales after 2035 could be plug-in hybrids, which run on batteries and gas, but the rest must be powered solely by electricity or hydrogen.
The European Parliament in June backed a plan to effectively prohibit the sale of gas and diesel cars in the 27-nation European Union by 2035, and Canada has mandated the sale of zero-emission cars by the same year.
California climate officials say the state’s new policy is the world’s most ambitious because it sets benchmarks for ramping up electric vehicle sales over the next 13 years.
The first mandated threshold comes in 2026, when one-third of all vehicles sold in the state must be zero-emission. Automakers could be fined $20,000 per vehicle sold short of that goal.
About 16% of cars sold in California in the first three months of this year were electric.
Washington state and Massachusetts already have said they will follow California’s lead, and many more are likely to — New York and Pennsylvania are among 17 states that have adopted some or all of California’s tailpipe emission standards that are stricter than federal rules.
Kia Corp.’s Laurie Holmes said the company plans to spend $25 billion by 2025 on electric vehicles and hopes to offer seven models by 2027.
But she and several other representatives of auto companies expressed concern about the state’s timeline given factors such as supply chain challenges and the high cost of materials to build electric cars.
“Automakers could have significant difficulties meeting this target given elements outside of the control of the industry,” she said.
The switch from gas to electric cars will drastically reduce emissions and air pollutants, but the transition will be painful for the state’s oil industry. California remains the seventh-largest oil-producing U.S. state, though its output is falling as it pushes forward with climate goals.
California shouldn’t wrap its entire transportation strategy around a vehicle market powered by electricity, said Tanya DeRivi, vice president for climate policy with the Western States Petroleum Association, an oil industry group.
“Californians should be able to choose a vehicle technology, including electric vehicles, that best fits their needs based on availability, affordability and personal necessity,” she said.
California is the nation’s most populous state, with about 39 million people. They account for 10% of the U.S. car market but have 43% of the nation’s 2.6 million registered plug-in vehicles, according to the air board.
