Core Sustainability Goal
• Incorporate sustainable practices in our day-to-day operations, reduce fleet emissions and improve the efficiency of the fleet strategically by trying new methodologies and technology.
![Page 5: Western States Highway Equipment Managers Association AASHTO Equipment Management Technical Services Program Partner 43 rd Annual Conference WSDOT Fleet](https://reader035.vdocument.in/reader035/viewer/2022062421/56649e395503460f94b2ad40/html5/thumbnails/5.jpg)
Fleet Goals• Reduce fuel consumption.• Reduce emissions with technology, alternative fuels, and
hybrids.• Operate a robust preventative maintenance program.• Maximize utilization to optimize fleet size, increase
efficient use and meet minimum use criteria set by OFM.• Increase engine operating efficiency with new
technology and equipment.

#1 Challenge to reducing fuel consumption and emissions
• Operation needs drive consumption.– Construction projects– Weather events– Snow and Ice control– Responding to accidents

Washington State Mandates
• Reduce emissions below 2005 levels• Use 20% biodiesel• By 2013, 40% of all fuel use must be from electricity
or biofuel• OFM Minimum Use Rule• Passenger vehicle fuel economy requirements• Governor directed 5% fuel reduction

AccomplishmentsUsing 2008 as the baseline, WSDOT has:
reduced our fuel use
increased our B100 gallons purchased by 80%
purchased 45% more hybrid vehicles.
reduced passenger-carrying vehicle inventory by 20%
reduce privately-owned vehicle miles travelled for state business by 34%.

Additional Highlights• Adjusted PM schedules to using fuel usage as a basis versus
time intervals
• Installed shift lights in heavy trucks’ dash to let driver’s know the best time to shift gears
• No Idle Policy and Fuel Conservation Policy
• Replaced incandescent lights with LED lights
• Diesel truck retrofits to reduce emissions

Biodiesel• Started using biodiesel May 2005 • Western Washington
• 47 WSDOT fuel sites @ B20 or higher– 12 sites @ B25 or higher
• Eastern Washington• 46 WSDOT fuel sites
– 25 @ B10 or higher

Challenges
• Biofuel costs more than diesel.• Biodiesel has propensity to gel in cold weather.• Tank and filter maintenance is critical in maintaining fuel
quality.• Biodiesel has a short “shelf life”.

Strategies to Reduce Emissions
• Convert 360 sedans and small SUVs to hybrid/electric
• Reduce fuel consumption by an additional 5%
• Increase biofuel use
• Transition approx. 348 heavy vehicles from gas to diesel
