Promoting Green Supply Chains in North America Progress and Perspective Arnold Maltz, Ph.D. April 22, 2008 Promoting Green Supply Chains
The Two Sides of the Issue • Resource Use • Enforced by price • The “Easy” Sell • Subject to the customer test • Environmental Impact • An “externality” from the firm’s perspective • Enforced by regulation • Trade-offs Promoting Green Supply Chains
Rail vs. Truck (1)Fuel Efficiency • Fuel efficiency – measured inton-miles per gallon • Rail current state:400 ton-miles per gallon (AAR) • Truck current state:130 ton-miles per gallon (estimate) Promoting Green Supply Chains
Rail vs. Truck (2)Accessibility Promoting Green Supply Chains
Rail vs. Truck (3)Service Performance • On time delivery (anecdotal)Truck 92%-95%Rail 83%-87% • Transit time ??? • Other customer issues Promoting Green Supply Chains
Rail vs. Truck (4)Results • Market Share – Ton-miles (w/o pipeline) 1996 2005Rail 42.8% 47.7%Truck 33.0% 35.6% • Market Share - $ (2006)Rail 6.7% Truck 79.3% Promoting Green Supply Chains
Rail vs. Truck (5)Cost Drivers • Fuel costs per ton-mileRail $.009Truck $.031 • Labor cost (wage only)Rail $.0003 (rough estimate)Truck $.0170 (rough estimate) Promoting Green Supply Chains
Expectations • Rail will take share of longer haul business, but gradually. • Infrastructure growth limited by access to capital and environmental acceptability • Work force issues • Availability of equipment • Customer acceptance • Rail impact on the environment is not negligible.

Regulatory Actions for aGreen Supply Chain Promoting Green Supply Chains
Highway Diesel Engine • Rule made in 2000, in effect with 2007 engines. • Lower sulfur fuel content from 500 ppm to 15 ppm (97% reduction) • 90% reduction in particulate matter • Significant reduction in Nox • Additional reduction in 2010 • Higher costs per truck ($8,000-$12,000) and for fuel and maintenance. • Lower fuel efficiency (7 mpg-6.5 mpg) Promoting Green Supply Chains
Highway Diesel - Mexico • As of July, 2008, new Mexican trucks to meet 2004 U. S. standards; OK unitl 2011. • ULSD begins in 2008, but long term conversion. Promoting Green Supply Chains
Port Cleanup (LA/LB) • 80% decrease in emissions by 2012 (mix of DPM, Nox, Sox) • $35/teu fee to penalize non-conforming, finance upgrades • Disagreement on owner-operator vs. licensed drayage company approach • Increased cost, but much higher under LA approach Promoting Green Supply Chains
Non-Highway Diesel • Locomotive and marine diesel to conform to 2007 standards, over time. • Must use ULSD fuel, a major change • Final results by 2012 and 2014 Promoting Green Supply Chains
Some Company Programs Promoting Green Supply Chains
Wal-Mart • Fuel efficiency improvement for private fleet • “No idle” and APU programs • 25% initial effort (end of 2007) • 100% improvement by 2015 • Better network and packaging design, as well as supplier score cards • Store redesign??? Promoting Green Supply Chains
UPS • Phasing in compressed natural gas (CNG) for urban deliveries • 20% less emission than optimal diesel • 10% better efficiency than optimal diesel • Approximately 1,000 currently deployed in U. S., and 700 overseas, with multiple alternative models Promoting Green Supply Chains
DPWN • Reduce carbon footprint by 30% by 2020 • Upgrade aircraft • Improve warehouses and sorting centers • GoGreen shipping service allows customers to offset shipping related emissions (in Europe since 2006) Promoting Green Supply Chains
