Freight Impacts
10
• Transportation is the second largest contributor to greenhouse gases (after electricity generation). It plays a significant role because the industry relies so heavily on oil.
• Moving freight in the U.S. accounts for 20 percent of energy consumed by the transportation sector
Freight Impacts
• The Department of Energy has set a goal of reducing petroleum use by 20 per cent in large trucks by 2050
• It expects weight reduction to be a big part of that effort as fleets deploy new trucks and trailers built with weigh saving materials.
11
• Using Alternative Fuels• Driving Efficiently: Tire pressures and air conditioner• Reducing Packaging: It represents approximately 5% of the
shipping weight of consumer goods and an unknown but certainly significant amount of volume.
• Slowing Down: Slowing down 13 percent (from 75 mph to 65) will reduce fuel consumption by 27 percent.
• Consolidating: Increasing load capacity utilization is one of the most effective ways of reducing carbon caused by shipping.
• Optimizing Routes: Computer programs can help design the most efficient routes, taking into account traffic patterns and the likelihood of delays.

Making Freight Transport More Efficient
12
• Low collaborative solution provide cost to visibility to Shippers and Carriers by identifying potential opportunities to reduce empty backhaul capacity.
• A web based Service to match carrier availability (empty miles) with transportation demand (loads) delivered through a members only internet portal.
• A toolset comprised of collaborative processes, cost and emissions savings Benefits calculator, negotiating
VICS Empty Miles
checklists, legal agreement templates, and standard data definitions to use the service.

Case Study: Coca Cola• Partnership with Eaton Corp developing Hybrid Diesel
Delivery Trucks• Currently, 170 Hybrid electric heavy delivery trucks in the
US and Canada– Decreased emissions by 37%– Increased mileage by 32%
15
• Idle Time Reduction– Automatic shutoff installed on all tractors– 14% reduction in idle time– Estimated annual fuel savings – 75,000 gallons
• Collaborate to Eliminate Dead-head Miles– 5-7% reduction on line-haul loads– Estimated annual fuel savings – 53,000 gallons
• Equipment Efficiencies– Use of lightweight trailers– 42% of weekly orders moved with lightweight trailers– 12% fewer loads for equivalent # of cases– Estimated Fuel Savings – 9,500 gallons

16
• Using friction reducers on the wheel-to-rail interface
• Improving trailer positioning on trains to reduce drag
Case Study: BNSF
• Using hybrid switch engines, such as the Green Goat, which use 40 to 70 percent less diesel fuel and reduce particulate emissions by 80 to 90 percent
• Adding idle control mechanisms that reduce fuel consumption and emissions
17
Fleet Impacts
18
• The nation’s corporate fleets drive about twice the rate of personal vehicles, representing a major opportunity for fuel efficiency efforts.
• Fluctuating gas prices, coupled with corporate sustainability commitments, have cast a spotlight on green fleet initiatives that can save money and boost reputations.
• Elements to consider include cost, alternative fuel infrastructure limitations, resale potential, and driver behavior, to name a few.
• Fleet management companies have stepped in the fill the demand with services including fleet greenhouse gas measurement and driver education.

Fleet Impacts
19
• Still, cost is viewed as a major obstacle to reducing fleet impacts. – Newer technologies in passenger vehicles, such as gasoline-
electric hybrids, can carry a purchase price premium that may be difficult to recoup in the projected lifetime of some vehicles
– For some larger vehicles, such as cargo vans, hybrid technology is limited or nonexistent.
– Pushback from drivers and attractive manufacturer incentives for less-efficient vehicles can also slow the transition from larger trucks to greener fleets.

Employee Commuting
21Source: GreenBiz.com,“The State of Green Business,”: (2009)
Employee Commuting
• Public transit systems, in many cases resembling a hub-and-spoke model don’t always offer a convenient alternative to workers who commute suburb to suburb.
• Overall commuting patterns in recent years have idled. • Workers value their cars because driving alone is perceived
to be the fastest way to get to work.
22
• Interest in public transportation has grown as employers search for ways to ease their workers’ commutes. Some cities are concerned, borne of the need to ease congestion and pollution.
• Massachusetts for example, created a law requiring that employers offer workers transit benefits; other States and Countries have similar programs in place.
Employee Commuting
23
Telecommuting
24
• A “telecommuter” is defined as someone who works from home at least three days a month as part of an arrangement with an outside employer.

Telecommuting
25
• Telecommuting programs – Employer-subsidized phone lines and furniture to boost work-life
balance and reduce commuting costs– Often leads to happier, more productive workers, too. – Can also save money for both workers and employers;
• A study found that individual workers save more than $1,700 in gasoline and vehicle wear and tear, while home office equipment typically consumes about half the energy as standard office equipment.
• Companies have also turned to telecommuting to trim their carbon footprints. – Cisco tested its telecommuting technology on about 20% of its
staff cutting GHG emissions by about 30,000 tons a year

Hybrids
27
How do Hybrid Cars Work?• Gasoline Power vs. Electric Power
– The gasoline-electric hybrid car is just what it sounds like -- a cross between a gasoline-powered car and an electric car.
– A gas-powered car has a fuel tank, which supplies gasoline to the engine. The engine then turns a transmission, which turns the wheels.

– An electric car, on the other hand, has a set of batteries that provides electricity to an electric motor. The motor turns a transmission, and the transmission turns the wheels.

• Produce 80% less• Toyota Prius produces 3.5 tons per year.
• H3 produces 12.2 tons per year
