California, the country’s most populous state and the center of U.S. car culture, is banning the sale of new gasoline-powered vehicles starting in 2035, marking a historic step in the state’s battle against climate change.
The rule, issued by the California Air Resources Board on Thursday, will force automakers to speed up production of cleaner vehicles beginning in 2026 until sales of only zero-emission cars, pickup trucks and SUVs are allowed in the state.
The unanimous vote comes after Gov. Gavin Newsom set a target in 2020 to accelerate the shift away from internal combustion engines. The transportation sector represents the largest source of greenhouse gas emissions in California, which has suffered from record-breaking wildfires, droughts and air pollution made worse by climate change.
The decision will have sweeping impacts beyond California and will pave the way for other states to adopt the requirement. At least 15 states, including New Jersey, New York and Pennsylvania, have adopted California’s vehicle standards on previous clean-car rules.
Liane Randolph, chairwoman of the California Air Resources Board, said the rule is one of the state’s most important efforts yet to clean the air and will lead to a 50% reduction in pollution from cars and light trucks by 2040.
The policy will not ban people from continuing to drive gas cars or from buying and selling them on the used market after 2035. The rule will also allow automakers to sell up to 20% plug-in hybrids, which have gas engines, by 2035.
But the rule does phase out such vehicles over time, requiring 35% of total new vehicle sales to be powered by batteries or hydrogen by 2026 and 68% by 2030. More than 16% of new cars sold in California in 2022 were zero-emissions vehicles, the state said, up from 12.41% in 2021 and 7.78% in 2020.
“California is once-again leading the way by establishing commonsense standards that will transition to sales of all zero-polluting cars and light-duty trucks in the state,” said Kathy Harris, clean vehicles advocate at the Natural Resources Defense Council.
California, home to congested freeways and smog-filled skies over cities like Los Angeles, has considerable authority over the country’s auto industry.
A federal waiver under the Clean Air Act allows the state to adopt stronger fuel economy standards than those of the federal government and has set the precedent for the rest of the country on how to curb vehicle emissions.
California’s ability to control vehicle emissions has spurred some innovative strategies, like catalytic converters that convert toxic gases and pollutants in exhaust gas into less-toxic pollutants, as well as “check engine” lights. The state established the first tailpipe emissions standards in the country in 1966.
The Trump administration in 2019 revoked California’s authority to regulate its own air quality, but the Biden administration restored that authority earlier this year.
State officials said the rule is critical to meeting to state’s goal to transition to 100% renewable energy by 2045, and that resulting emissions reductions would lead to fewer cardiopulmonary deaths and emergency visits for asthma and other illnesses.
However, meeting the timeline will face challenges, including installing enough charging stations across the state and having adequate access to materials needed to make batteries for electric vehicles.
John Bozzella, president and CEO of the Alliance for Automotive Innovation, which represents major automakers, said California’s mandate would be “extremely challenging” for automakers to meet.
“Whether or not these requirements are realistic or achievable is directly linked to external factors like inflation, charging and fuel infrastructure, supply chains, labor, critical mineral availability and pricing, and the ongoing semiconductor shortage,” Bozzella said in a statement. “These are complex, intertwined and global issues.”
The rule comes after President Joe Biden signed the Inflation Reduction Act earlier this month, which provides funding for electric vehicle tax credits and clean vehicle manufacturing facilities. The Biden administration also issued new nationwide limits on tailpipe emissions last year for new cars and light trucks made through 2026.
Environmental groups praised the decision on Thursday, though some argued that the board needed to set even tougher targets to meet the urgency of the climate crisis. Some groups had previous urged the board to impose a rule to achieve 100% zero-emission vehicle sales by 2030, five years earlier than the actual regulation.
“This rule needed to match the urgency of the climate crisis and instead leaves Californians making sputtering progress in the slow lane,” Scott Hochberg, an attorney at the Center for Biological Diversity’s Climate Law Institute, said in a statement.
“California needs to act strongly on gas-powered cars instead of ignoring them, and shift to EVs much sooner or watch our climate stability slip away,” Hochberg said.
Daniel Barad, California senior policy advocate at Sierra Club, said in a statement that the rule is “a major step towards breathable air in California communities, and will be critical for the state to meet its climate goals and emission reduction targets.”
“Other states should move swiftly to join California and adopt this life saving rule, which will improve air quality and help slow the climate crisis,” Barad said.
