Governor Jerry Brown has expressed an interest in banning the sale of combustion-engine cars, Mary Nichols, chairman of the California Air Resources Board, told Bloomberg.
The proposed ban could be at least a decade away, she added.
“There are people who believe, including who work for me, that you could stop all sales of new internal-combustion cars by 2030. Some people say 2035, some people say 2040,” she said. “It’s awfully hard to predict any of that with precision, but it doesn’t appear to be out of the question.”
In California, more than 2m new vehicles were registered last year, topping the number of new cars in France, Italy or Spain.
