Greening the Fleet

The 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 on Energy Efficiency, Conservation and Climate Change continues to promote an efficient fleet mix and use of efficient, low emission vehicles to lower the dependence on petroleum as well as reduce emissions of air pollutants and greenhouse gases. Through a combination of regulation compliance, state purchasing policies, and innovative demonstrations we have implemented renewable diesel, battery electric and plug-in hybrid vehicles, solar-powered equipment, propane-fueled vehicles, hydrogen fueled vehicles, low dust street sweepers, diesel particulate filters on heavy-duty diesel-powered vehicles, and the use of E-85 fuel ethanol. Also, in the South Coast Air Quality Management District, we are employing the use of compressed natural gas when replacing our larger fleet.
