From the article:
Under a state mandate enacted last year, 35% of cars sold in California, beginning with 2026 models, must be zero-emissions, ramping up to 68% in 2030 and 100% in 2035.
IRT to my post 26 an older Calmatters article suggests how the enforcement might work.

From the article:
“To ensure enforcement, state officials could penalize manufacturers that don’t meet their yearly percentages with hefty fines of $20,000 for every car they fail to produce in a given year, according to air board staff. Automakers that fail to meet those requirements would need to get credits from another manufacturer that already met their targets. Air board staff also assured the public that they could amend the regulation at any point to address lingering equity and compliance issues.”
