Caltrans Fleet Greening

The Caltrans Fleet Greening Program began as a five-year plan in August 2000 to reduce emissions from the Caltrans fleet, stay ahead of emerging regulations, and set the example for the use of emerging, clean air technologies. Today the Director’s policy continues to promote an efficient fleet mix and use of efficient, low emission vehicles to lower Caltrans’ use of petroleum as well as reduce emissions of criteria air pollutants and greenhouse gases. Through a combination of regulation compliance, state purchasing policies, and innovative demonstrations we’ve implemented , for example, hybrid passenger vehicles, solar-powered equipment, propane-fueled vehicles, low dust street sweepers, diesel particulate filters on heavy-duty, diesel-powered vehicles, two hydrogen demonstration vehicles, and an E-85 fuel ethanol demonstration project.
