Energy Use by Mode of Transportation
National Transportation Statistics 2013
Total US Energy use in 2013: 26 Quadrillion Btu
US Must Take Lead for Addressing CO2
More States And Cities Are Taking Action On Climate Change
States with Climate Action Plans: 34

Health Effects of Diesel Emissions
• Two main categories of diesel exhaust:– Gases: non-toxic and toxic components
• Volatile Organic Compounds (VOC)
• Oxides of Nitrogen (NOx)
– Particles: fine/ultrafine and toxic chemicals absorbed onto them
Pollutants react with oxygen and make ozone
}
More about particulates...
Health Effects of Diesel Emissions (continued)
Particulate Matter (PM)
• Small particles of dust, dirt, soot, smoke, liquid droplets, and organic chemicals
• EPA regulates PM in two categories:– PM10 (10 microns or less)– PM2.5 (2.5 microns or less)
• PM2.5 is very small, 1/30th of the width of a human hair– Small size allows PM2.5 to get through the human body’s
airway defense mechanisms and enter deep into the lungs
2.5 Microns
Health Effects of Diesel Emissions (continued)
What health and environmental effects have been linked to high PM concentrations?
• Respiratory Problems• PM, especially PM2.5 can enter deep into the lungs and
bloodstream• Aggravated asthma, coughing, painful/difficult breathing,
chronic bronchitis, decreased lung function, premature death
• Visibility• Haze problems in national parks
• Atmospheric deposition• Can cause high acidity in lakes and streams• Can change soil nutrient concentration• Can damage sensitive plants and crops
Regulatory Approaches
• Criteria Pollutant Regulations (PM and Ozone)
• Fuel Regulations
• Engine Standards
What You Can Do
Improving Your Truck’s Efficiency
• Idle Reduction– Policies– Onboard Devices– Shore Power
• Fuel Efficiency– Tires– Aerodynamics– Driver
Behavior/Incentives
When a vehicle is running for nonpropulsion purposes, it is idling.
• Trucks idling while in queue• Vehicles waiting to
load/unload passengers or goods
14
Running emergency lights and other auxiliaries• Emergency vehicles, utility vehicles
Powering HVAC•All vehicle types, for operator and passenger comfort in extreme weather
Performing nonpropulsion (PTO) work•Bucket trucks, sewer-line maintenance trucks, wood chippers
Some Idling Is Unavoidable
Most Idling Is Not
Waiting in queue•Delivery trucks, transit buses and motor coaches, shuttle buses, taxis
Engine warming•Today’s vehicles warm up faster by being driven than idling
Sitting in vehicle•During lunch breaks, to complete paperwork, to make phone calls
• Idling a car wastes up to 0.5 gallons of fuel per hour.
• Idling a medium-duty truck wastes 0.4 to 0.6 gallons of fuel per hour.
• Idling in the U.S. uses more than 6 billion gallons of fuel at a cost of more than $20 billion EACH YEAR.
• Engine idling increases vehicle maintenance costs.
• Engine idling can shorten vehicle life.
The Cost of Idling Adds Up
Idle Reduction Policies
Elements of Idle Reduction Policies
• Clear signage• Communicated well –
to drivers and management
• Reduced detention time (at facilities)
• Proper staging of cargo
• Driver comfort stations
• Queue Scheduling
• Sufficient drayage equipment

Onboard Idle Reduction Technologies
Average fuel savings Emissions ControlledTrucks: 1 gal/hr CO2, NOx, and PM
Rail: 4 - 12 gal/hr
• Automatic Shut-Down/Start Up System • Battery Powered Systems• Diesel Driven Heating System• Auxiliary Power Unit/Generator Set
Auxiliary Power Unit (APU)
• Mounted externally
• Small Engine/Generator Combination– HVAC– Electrical accessories
Bunk Heaters/Battery Air Conditioners
Heaters
•Use very little fuel
BAC’s•Store energy as truck operates•Can work up to 16 hours
Automatic Engine Shutdown (AESS)
• Start and stop truck automatically
• Can be programmed to meet idle rules
• Can be programmed for temperature

Aerodynamics - Tires
27
Average fuel savings Emissions Controlled
Trucks: 4 - 5% CO2, NOx
• Single-wide tires and aluminum wheels– Reduced rolling resistance
– Reduced weight
• Low rolling resistance duals can be as effective
as singles
Tires (continued)
• Single-wide tires Can Reduce 800-1000 lbs (when used on drive and trailer axles)– Reduced fuel consumption– Increased cargo capacity
• Low rolling resistance – better mpg– 2% to 5% compared to conventional tires
Benefits of Low Rolling Resistance Tires
29
• Incremental fuel savings demonstrated for the tractor, trailer & combination
• Benefits demonstrated with new and retread tires
• SAE 2014-01-2425

configurations
– Now has SmartWay Trailer and SmartWay Elite levels
– New test methods for verifying trailer aerodynamic components are more rigorous and incorporate multiple test protocols (i.e., track test, wind tunnel, coastdown, and computational methods)
– SmartWay tire program recently expanded to include verified low rolling resistance retread and wide-based tires.

– 72,000 tons PM
National Clean Diesel Campaign & Midwest Clean Diesel Initiative
What is MCDI?
A public-private partnership formed in 2004 with a goal to address 1 million ‘legacy’ diesel engines by 2010 (we did!)
MCDI Leadership Group: (initially) 33 public-sector and private-industry organizations. Meets yearly to discuss progress, raise issues
MCDI Co-Chairs: EPA, Cummins, ALA, Illinois EPA; choose general direction of the Initiative
What is MCDI? (continued)
State Coalitions:– Government, industry, and nonprofit
organizations– Address diesel pollution through projects,
legislation, and innovative financing
Communication tools:• www.epa.gov/midwestcleandiesel• Webinars• To get on board:
How MCDI Reduces Diesel Emissions“The 5 R’s”
– Retrofit– Repower– Replace– Rebuild– Refuel
Each can reduce emissions and/or fuel use
