Biodiesel for buses cuts carbon footprint
Summary Information
Although electric light duty consumer vehicles are now widely available, the heavy duty vehicle market has proven harder to electrify. One way to reduce emissions from heavy duty vehicles without having to electrify vehicles is to switch to biodiesel.
As part this broader effort, the University of California at Santa Cruz ran a pilot program with biodiesel buses. The University converted its entire regular diesel bus fleet to biodiesel in January 2019. Research teams then monitored the effects and estimated the carbon emissions reduction from this switch.
In the end, switching to biodiesel buses reduced CO2 emissions by an estimated 25 percent.
