- Tracking odometer readings and fuel usage provides information needed to better optimize vehicle usage for minimum cost and gives early warning of vehicle problems.
- Vehicle energy usage data is critical to complete accounting and regular reporting of progress toward financial, energy-reduction and carbon-emission targets.
- Fleet-management software can track fuel and odometer readings, link to existing fuel-card systems, and cut time and expense from fleet management by eliminating paperwork.

Select the most efficient vehicle for each day’s use
- Require employees to select the car or truck that matches that day’s tasks.
- Use cars or minivans, not SUVs, for moving people.
- Use 2wd trucks for towing, dirty jobs and hauling large objects.
- Use 4x4 trucks or SUVs only for off-road jobs or inclement weather.
- Do not permanently assign large vehicles or 4x4s to individuals, unless that person’s job requires off-road or inclement weather driving for a majority of the time.

Reduce vehicle miles traveled (VMT)
- Use carpools to and from work, and between work sites for jobs or meetings.
- Use teleconference, videoconference and webinar options when possible to eliminate trips.
- Leverage IT staff to identify and eliminate gaps in or barriers to teleconference, videoconference and webinar tools.
- Telecommute from home if job function permits.
- Use public transit, biking or walking between facilities whenever possible. Keep a fleet of bicycles for staff to use for nearby errands.
- Develop a VMT reduction outreach and education program for employees.

- Aerodynamics: Put racks, ladders and tools on vehicle roofs only when needed that day
- Routinely check tire pressure.
Note: tires inflated with nitrogen stay fully inflated longer. More information from the nonprofit GetNitrogen Institute of Denver.
- Use low rolling resistance (LRR) tires to achieve fuel savings of 2 to 10 percent.
- Cars: Goodyear FuelMax, Bridgestone Ecopia, Michelin Energy Saver A/S
- Trucks: Goodyear FuelMax (dual), Michelin X-One (wide-base)
- Note: Low rolling resistance does NOT mean low traction. LRR tires use improved internal construction to reduce the energy absorbed inside the tire during each rotation. Truckers using wide-base tires actually report improved traction in snowy conditions.
< Back to recommended actions list
- Avoid fast acceleration, hard braking and unnecessary idling.
- Use good planning to combine trips and identify efficient routes.
- Choose the most efficient vehicle you can for the trip.
< Back to recommended actions list
- 4x4 vehicles use more fuel per mile than 2wd vehicles.
- Create a motor pool for shared use of low-efficiency vehicles such as SUVs and 4x4s.
- Pre-arrange agreements with rental companies for special needs.
- Do not permanently assign large vehicles or 4x4s to individuals, unless that person’s job requires off-road or inclement weather driving for a majority of the time.
- Director-level approval recommended for any 4x4 purchases.

Use the 10-year life cycle cost in vehicle purchase planning
- When planning a vehicle purchase, quantify the net present value of vehicle fuel usage over a 10-year period.
- Always purchase vehicles with the lowest overall life cycle cost over high cost vehicles.
- Purchase advanced technology vehicles with higher purchase price but lower lifecycle cost.
- Do not use artificially low fuel prices.
- Do not include unrealistically high maintenance costs of for advanced vehicles.
< Back to recommended actions list
- Retire low-mileage vehicles whenever possible.
- Purchase vehicles with the highest possible mileage for a given need.
- Purchase hybrid-electric vehicles whenever they fit the need.
- Purchase multi-fuel vehicles when possible: gas-ethanol or diesel-biodiesel.
- Purchase neighborhood electric vehicles (NEVs) for low-speed tasks in and around town.
- Note: House Bill 1228 requires state government to purchase only flex-fuel or hybrid vehicles, subject to availability, unless the cost is 10 percent higher than a comparable non-flex-fuel or non-hybrid vehicle.

- Plan for purchase of plug-in hybrids (PHEVs) in 2010
- Vehicles will operate on plug electricity and as a gasoline-electric hybrid.
- Designed to charge overnight from any 110 volt wall plug.
- Efficiency will range from 50 to 150 mpg.
- Passenger cars will be on the market in 2010, cargo vans by 2012.
- Plan for purchase of electric vehicles in 2010
- Electric vehicles are planned by many manufacturers (domestic & foreign)
- Electric vehicles will be available in many vehicle types (cars/trucks/vans)
- Electric vehicles will be all-weather, highway-capable with significant cargo capacity
- Cargo vans, delivery trucks, and cars will all be available in 2010
- Prepare for new technology
- When repaving sidewalks or parking lots, bury electrical conduit to allow for future plug-in parking spaces.
- When designing or remodeling buildings, include 110 volt outdoor outlet plugs near parking spaces and size circuits for future installation of fast-charging 240 volt outlet plugs for electric vehicles.

- Educate employees on how to maximize the use of ethanol and biodiesel fuels.
- Clearly mark all flex fuel vehicles and biodiesel vehicles with a sticker on the fuel door.
- Determine the feasibility of converting some motor pool pumps to dispense E-85 or biodiesel.
- Use locally available ethanol and biodiesel supplies.

Increase use of locally-produced natural gas as vehicle fuel
- Compressed natural gas tanks and fuel systems can be retrofitted on certain vehicles.
- Natural gas vehicle retrofit kits are EPA-certified to deliver equivalent emissions performance.
- Install compressed natural gas fueling stations at convenient locations.

Hydrocarbon and nitrogen oxide are smog-forming pollutants that pose a health hazard.- Pre-2000 vehicles are two times more polluting than current standards.
- Pre-1990 vehicles are 20 times more polluting than current standards.
- Soot particulates from diesel tailpipe emissions are cancer-causing. New diesel trucks have much lower particulate emissions.
- Heavy duty diesel engines built in 2007 and later (Class 4-8 trucks) are up to 95 percent cleaner than older vehicles.
< Back to recommended actions list
Reduce diesel particulate emissions in older diesel vehicles
- Adding diesel particulate filters to the exhaust of a truck, bus, refuse vehicle or piece of diesel equipment can cut cancer-causing particulate emissions by up to 90 percent.
- Fuel economy is not significantly changed.
- Carbon particulates are captured in the filter and incinerated by the hot exhaust.
- Reducing diesel particulate emissions reduces “black carbon” in our air. Black carbon emissions can form a layer on snow, and can contribute to asthma and impaired lung development in children.
