Fleet Greening

The Caltrans Fleet Greening Program began in August 2000 as a way to reduce emissions from the Caltrans fleet, 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 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.
