WASHINGTON: California has asked the Biden administration to approve its plan to require all new vehicles sold in the state by 2035 to be either electric or plug-in electric hybrids, a landmark move that could speed the end of gasoline-powered vehicles, according to a letter seen by Reuters.
The California Air Resources Board (CARB), which approved the plan in August, asked the Environmental Protection Agency (EPA) on Monday to approve a waiver under the Clean Air Act to implement its new rules that set yearly rising zero emission vehicle rules starting in 2026 and would end the sales of vehicles only powered by gasoline by 2035.
"These vehicles will permanently displace emissions from conventional vehicles," wrote CARB Executive Officer Steven Cliff, adding that motor vehicles and other mobile sources are the greatest source of emissions in California.
The Biden administration has repeatedly refused to endorse setting a date to phase-out the sale of gasoline-only vehicles.
EPA spokesperson Tim Carroll said "as with all waiver requests from California, we’ll follow an open public process in considering it, as the agency routinely does."
In a Reuters interview last month, EPA Administrator Michael Regan declined to say how the EPA would react to a California request. "We’ll be on the lookout for that if it were to ever come," Regan said.
Under an EPA proposal released in April to drastically cut vehicle emissions through 2032, automakers are forecast to produce 60% EVs by 2030 and 67% by 2032 to meet requirements, compared with just 5.8% of US vehicles sold in 2022 that were EVs.
California's zero-emission rules will cut by 25% smog-causing pollution from light-duty vehicles by 2037.
The rules mandate that 35% of the new cars sold be plug-in hybrid electric (PHEV), EVs or hydrogen fuel cell by 2026. That proportion will rise to 68% by 2030 and 100% by 2035.
The 60-page California waiver request seen by Reuters says through 2040, California's zero emission rules will cost US$210.35 billion but have total benefits of $301.41 billion.
A growing number of states are adopting California's electric vehicle rules that are more stringent than what the Biden administration has proposed. Earlier this month, Rhode Island joined Washington, Virginia, Vermont, Oregon, New York, and Massachusetts in adopting the California requirements.
CARB's regulation would allow automakers to sell up to 20% PHEVs by 2035 and by then would need a minimum 80km all-electric range label to qualify.
