A California assemblyman introduced a bill that would require all new passenger vehicles sold in 2040 to be zero-emission vehicles.

The bill, which does not apply to large commercial vehicles larger than 10,000 pounds, was introduced by California Assemblymember Phil Ting (D-San Francisco) primarily to contribute to the efforts of combating climate change.

“It’s time that we clear the path for emissions-free transportation and take significant steps to achieve our ambitious emissions reduction goals,” said Ting.

Zero emissions vehicles cannot produce exhaust emissions of any criteria pollutant or greenhouse gas under any operational mode or condition, according to a release from Ting. The bill also does not apply to vehicles owned by people moving into California from other states.

In September 2017, Jerry Brown reportedly considered banning the sale of vehicles with internal-combustion engines in California.
