California Transit Agencies Must Convert to Zero-Emission Buses

California has become the first state in the nation to require public transit agencies to transition to only zero-emission buses, following a vote by its Air Resources Board on Friday.

The regulators told transit agencies to convert by 2040. It’s part of an Innovative Clean Transit measure passed by the board. Starting in 2029, all transit bus purchases in the state need to be zero-emission vehicles.

California already leads the nation in electric vehicle adoption. About 50 percent of all electric vehicles operating in the U.S. are on California roads.
