California is on the brink of banning combustion-powered vehicles, a move that could have wide-reaching effects throughout the U.S.

The California Air Resources board is expected to pass a motion that will require all cars sold by 2035 to produce no tailpipe emissions, effectively setting an end date for new ICE machines in the state because only battery-powered or hydrogen vehicles will meet the new legal requirements. The Trump administration had removed California’s ability to set its own emission standards, but that right was reinstated by the new Democrat government.

But carmakers can’t take that 2035 date as a simple switch from dirty to clean cars. The legislation would also implement something called the CARB Advanced Clean Cars II rule that sets increasingly tough emissions standards in the years running up to 2035, including a requirement for 70 percent of new vehicles to emit no tailpipe nasties by 2030.

A 2035 ICE ban is great news for automakers like Tesla, which builds cars in California

A 2035 cut-off for combustion vehicles brings California into line with mainland Europe following the European Union’s decision earlier this year to ban ICE cars from the middle of the next decade. The UK’s tougher stance means fossil-fuel vehicles will be outlawed there by 2030, a date news reports last year suggested California might also adopt, and Norway is going green in 2025.

California has led the way on North American emissions reductions measures going back to the early 1960s. And while other states were, and are, under no obligation to match those targets, the technology fitted to cars to meet California clean limits was later adopted nationwide and benefited air quality around the country.

Also benefiting from California’s ICE ban are the numerous electric vehicle manufacturers located in the state, which will see demand increase, potentially generating more jobs and revenue. But California isn’t the only state seeking an end to sales of ICE vehicles. Eleven other states are currently encouraging Washington to implement a nationwide ban on gasoline and diesel-powered light vehicles.

A 2035 ban on combustion cars in California will, of course, only apply to new vehicles. But given that many cars and trucks have a lifespan of less than 15 years, it’s likely that gas-powered vehicles, and gas pumps, will be a rare sight in the state by 2050.
