Fleets

When buying or leasing new vehicles, California government fleets are required to follow certain State and Federal policies in order to help reduce petroleum dependence and protect the environment. In addition, many private organizations are also looking to green their fleets and have included voluntary purchase guidelines for low emission, high efficiency and/or alternative fuel vehicles. Whatever your green vehicle purchase goals are, DriveClean.ca.gov has the vehicle emissions data and the search tools to help you find what you need.

Finding Vehicles that Meet Your Fleet's Criteria

DriveClean.ca.gov provides emissions information for all vehicles certified in California dating back to the 2000 model year. Vehicles can be searched in a variety of ways and sorted based on their Fuel Economy and Environment Label (label) ratings that indicate their smog and greenhouse gas impact. The higher the rating, the cleaner the vehicle is. Here are some tips on how to use DriveClean.ca.gov's vehicle searches to get the list of qualified vehicles that meet your fleet needs.

Searches can be generated to include vehicles that:

  • Meet specific emissions certification levels (SULEV, LEV II ULEV, etc.)
    California's emissions certifications equate to a Smog Rating which are outlined in this conversion chart. Once you know what Smog Rating you are looking for, you can perform a Smog Rating search.

 

  • Have the fewest smog-forming emissions
    Vehicles with the HIGHEST Smog Ratings emit the least smog pollution. You can search vehicles by Smog Rating, or by any search method and then sort by the cleanest score within your search results.

 

  • Have the smallest carbon footprint
    Vehicles with the HIGHEST Greenhouse Gas Ratings have the fewest greenhouse gas emissions, and tend to be more efficient vehicles in general. You can search vehicles by Greenhouse Gas Rating, or by any search method and then sort by the cleanest score within your search results.

 

  • Are the cleanest, most efficient alternative fuel models:

    Battery electric
    You can search battery electric vehicles (EVs) on the market this year, or in previous years by adjusting the viewable year within your results. Since all pure battery EVs are zero emission, they have the cleanest (highest) possible scores for both smog and greenhouse gas.

    CNG
    You can search light-duty CNG vehicles on the market this year, or in previous years by adjusting the viewable year within your results. You can then sort by the highest Smog Rating to find out which models have the fewest smog-forming emissions, or by the highest Greenhouse Gas Rating to find vehicles that have the smallest carbon footprint and are the most fuel efficient.

    DriveClean.ca.gov provides only light-duty vehicle information, however a list of medium-duty CNG vehicles can be found on ARB's single occupancy carpool lane webpage under Qualifying Vehicles for Clean Air Vehicle Decals.


    E-85
    You can search E-85 vehicles on the market this year, or in previous years by adjusting the viewable year within your results. You can then sort by the highest Smog Rating to find out which models have the fewest smog-forming emissions, or by the highest Greenhouse Gas Rating to find vehicles that have the smallest carbon footprint and are the most fuel efficient.

    Hydrogen
    You can search hydrogen fuel cell vehicles on the market this year, or in previous years by adjusting the viewable year within your results. All hydrogen fuel cells are zero emission and have the cleanest (highest) possible ratings for both smog and greenhouse gas.

    Diesel / biodiesel capable
    You can search diesel vehicles on the market this year, or in previous years by adjusting the viewable year within your results. You can then sort by the highest Smog Rating to find out which models have the fewest smog-forming emissions, or by the highest Greenhouse Gas Rating to find vehicles that have the smallest carbon footprint and are the most fuel efficient.

 

  • Are the cleanest, most efficient hybrids and plug-in hybrids:

    Hybrids
    You can search hybrids on the market this year, or in previous years by adjusting the viewable year within your results. You can then sort by the highest Smog Rating to find out which models have the fewest smog-forming emissions, or by the highest Greenhouse Gas Rating to find vehicles that have the smallest carbon footprint and are the most fuel efficient.

    Plug-in hybrid vehicles
    You can search plug-in hybrids on the market this year, or in previous years by adjusting the viewable year within your results. You can then sort by the highest Smog Rating to find out which models have the fewest smog-forming emissions, or by the highest Greenhouse Gas Rating to find vehicles that have the smallest carbon footprint and are the most fuel efficient.

 

  • Have a particular engine Test Group Number
    This search is most helpful when buying a used vehicle that you are not sure of it's emissions certification level. You can find the test group number (or sometimes called the "engine family number") under the hood of the vehicle. By entering that number into the Test Group Search, you can find out the smog rating, and even find any other versions of that vehicle that might have a different engine – and a different Smog Rating.

 

State of California Fleet Requirements

The California Department of General Services (DGS) Office of Fleet and Asset Management (OFAM) has created the Alternative Fuels Program to support the purchase and use of alternative fuel vehicles (AFV) within the state's fleet. The AFV Program works with the DGS Procurement Division developing the annual state vehicle purchasing contract to ensure specifications meet state fuel efficiency criteria, CARB's low emission standards and Federal AFV requirements. The AFV program submits annual compliance reports to the Federal Government for all state agencies, and it is also a technical resource on matters concerning AFVs, fueling, legislation, policy, and regulations. These are specific requirements for California State fleets:

  • EPAct Requirements
    Under Executive Order W-100-94 the OFAM must develop policies and procedures for the state fleet to comply with the Federal Energy Policy Act (EPAct) of 1992. EPAct set forth the statutory requirements for the acquisition of AFVs by Federal and State agencies in order to increase supply and demand for fuels other than gasoline or diesel, and reduce foreign oil imports. In fiscal year (FY) 2000 and beyond, 75% of light-duty vehicle (LDV) acquisitions in covered fleets must be AFVs. Vehicles that weigh less than 8,500 lb gross vehicle weight rating (GVWR) are considered LDVs.

 

  • Mandates for Gasoline and Hybrid-Electric Powered Vehicles
    After having met the Federal EPAct mandate, all gasoline-powered light-duty sedans purchased or leased by state agencies must be at a minimum certified to CARB's LEV II Ultra Low Emission Vehicle (ULEV) standards (*equates to a Smog Rating of 5). Light-duty pickups, vans, and sport utility vehicles must be at a minimum certified to CARB's LEV I ULEV standards or equivalent (*equates to a Smog Rating of 1). State agencies shall, when available, maximize the purchase or lease of available vehicles that meet or exceed CARB's LEV II Super-Ultra Low Emission Vehicle (SULEV) passenger vehicle standards for exhaust emissions (*equates to a Smog Rating of 8) and maximize the purchase or lease of hybrid vehicles that are substantially more fuel efficient.

    *Smog Ratings - Smog Ratings equate to particular emissions ratings, which are outlined in this Smog Rating / Emissions Rating Conversion Chart. The higher the Rating, the cleaner the vehicle is. Fleets can search vehicles that meet their requirements in a variety of ways on the home page.

 

  • Sport Utility and Four-Wheel Drive Truck Policies
    Public policy discourages the purchase or lease of sport utility vehicles (SUVs) and four-wheel drive trucks if other alternatives can meet an agency's business needs. State agencies must demonstrate the critical need for such vehicles, and priority consideration shall be given to the purchase or lease of an alteratively fueled or hybrid SUV or four-wheel drive truck.

 

Government Purchase Contracts

DGS's Vehicle Purchase and Lease Policy outlines vehicle contracts for the purchase of passenger cars, vans, utility vehicles, and both light duty and medium duty work trucks. Vehicles listed on these contracts are procured via environmental preference scoring (environmentally preferable purchasing).  Bidders earned points based on the pricing, the vehicles’ gas performance, emission standards and those who could meet window glazing specifications.  Points were also awarded for companies who are ISO 14001 certified. In addition, individual contracts are developed for Alternative Fuel Vehicles (AFVs) and hybrid vehicles. These contracts are available to all state agencies, local city and county governments, K-12 education, special districts, colleges and universities. Procurement methodologies may change in the future and are dependent on the contract specifications for each procurement cycle.
