This truck proposal is just more of the same: when considering credits, Option 1 gives away 12 percent of the first step of regulations (2027-2030), causing even further delayed action in an industry that hasn’t seen new tailpipe NO X regulation in over 20 years. Image: Freightliner ).

Under the Clean Air Act, California has the unique ability to set its own standards for tailpipe emissions from new vehicles, including greenhouse gases. There are some aggressive milestone requirements: 35% of new vehicles must be electric by 2026 and 68% in 2030. Other states can then piggyback on California’s efforts.

Today, the Union of Concerned Scientists (UCS) projects that 50 percent of US passenger car sales could very well be electric by 2030. Senate Bill 233 would require all EVs sold in the state to have bidirectional charging capacity by 2030. If that happens, EVs could make up 60 to 70 percent of the cars on US roads by 2050.
