Objective: Convey an understanding of the value of incorporating Green House Gas Emissions (GHG) into Supply Chain Design and discuss “How” to do this.

Key Elements:

– Impact on business and the environment

– Design activities in SCM that impact GHG

– Tools and techniques associated with Green Supply Chain Network Design

Strategy Formulation

Network Design Approach

• Define Boundaries

• Cost, Service, Capacity, GHG

• Model Configuration

• Convergent/Divergent Thinking

• What-if Analysis/Review

• Go-forward Plan

Page 9: Incorporating Green Considerations in the Supply Chain Design ...

Scoping Considerations

• Understand Corporate Goals for

Emissions Reduction

• Define Span of Supply Chain Control

and Influence

• Estimate Network Emissions

– Top Down vs Bottom Up

– Use of Government Information and

Other Sources

Visioning:Techniques to RevisitIn identifying alternative scenarios to test, keep in

mind techniques that can impact GHG emissions.

• Offshore Sourcing

• Packaging/Postponement

• Consumer Direct Shipments

• Inventory Policies

• Transportation Mode Shifts

• Cooperative Arrangements - Trans, Whs

GHG Analysis Options

• Climate exchanges exist to facilitate cap

and trade and social responsibility

• Exchanges trade contracts for 100 metric

tons of C02e offsets

• Offsets pay for the cost of projects which

offset carbon emissions

• Offset contract pricing can be utilized in

network modeling as a logistics cost

Carbon offsets may be used to approximate

“social costs” of GHG emissions

Tradeoff Analysis

Scenarios Comparisons

• Minimal cost solution reduces GHG by 25%

• Further 4% reduction in GHG: marginal costs $24 per tonne of GHG

• Next 20% reduction costs $36 per tonne of GHG; (1/2 of original GHG)

• Additional GHG reductions require significant cost increases

Baseline = 100%

Page 26: Incorporating Green Considerations in the Supply Chain Design ...

• Changed product deployment approach –

increased stock points on some categories

• DCs reduced from 6 to 3

• Reduced avg miles per delivery by ~310

• Reduced fuel/delivery by avg of ~ 60 gal

• Reduced C02e emissions per delivery by

an avg of ~ 1,100 pounds

Strategy balancing customer service, risk,

cost, lease commitments, GHG and flexibility
