California's transit buses are going green, the Associated Press reports, after the California Air Resources Board unanimously decided that all new buses have to be carbon-free by 2029, and that all old buses will be "phased out by 2040."
Details: This is the first mandate of its kind in the U.S., per the AP. 40% of California's greenhouse emissions come from the transportation sector, and the move is meant to "drastically" reduce those emissions in order for the state to meet its climate change goals.
