Fleet Strategy: With 16,000 power units, the YRC Worldwide companies have many opportunities to optimize equipment use and maximize efficiencies for environmental and corporate benefits.
Our fleet strategy centers on: equipment use, cleaner-burning fuels and fuel-efficient engines.
Equipment use
To minimize emissions, the newest equipment with the newest emission controls runs the most miles; older equipment runs the fewest miles.
| Unit Type | Approximate Average Annual Miles |
|---|---|
| Sleeper | 240,000 |
| Linehaul Day Cab | 180,000 |
| City | 30,000 |
Cleaner-burning fuels
To support environmental sustainability, we are testing alternative fuels. Our use of ultra-low sulfur diesel complies with EPA initiatives to reduce heavy-duty power-unit emissions.
- We introduced ultra-low sulfur diesel fuel in 2006.
- We introduced cleaner engines in 2007.
- After-market diesel particulate filters testing began in 2010.
- In 2011, we are planning to buy new vehicles with selective catalyst reduction devices, which greatly reduce NOx emissions.
We also use biodiesel fuel, an emerging alternative, which burns cleaner than petroleum-based diesel.
Cleaner-Burning Engines And Hybrid Vehicles
Cleaner-burning engines improve fuel efficiency and reduce our carbon footprint. Engines in linehaul power units are rebuilt to the newest EPA standards about every 5 years.
We added two low-emissions hybrid vehicles to the fleet in December 2008.
- The units are particularly effective in congested metropolitan areas.
- Diesel-electric hybrid technology benefits include 30-percent savings in fuel economy, quieter operation, reduced CO2 emissions and longer brake life.
- We are carefully evaluating each unit and may buy additional units if results are favorable.
