The movement towards green supply chain management is rooted in the concept of sustainability
“Sustainability is closely aligned with the concept of “triple bottom line” – expanding traditional reporting frameworks to take into account environmental and social performance in addition to financial performance – 1994, John Elkington
There is now abundant scientific evidence that humanity is living unsustainably. Returning human use of natural resources to within sustainable limits will require a major collective effort.
One major driver of human impact on Earth systems is the consumption of biophysical resources. The world population is projected to reach 7 billion early in 2012 (right)*.

Four primary factors drive business interest in being sustainable
Growing interest as business face continuous margin erosion, and energy prices remain volitile
A growing segment of customers favor companies that credibly demonstrate they are reducing carbon impact
Through trading permits, mandated caps, and other means, governments will increasingly press businesses to limit the amount of greenhouse gasses they release
The efficiencies that a company like Wal-Mart or Toyota can put in place to reduce emissions can reduce other costs and improve operations as well, increasing the competitiveness or their extended supply chain

Integrating Sustainability Into Your Supply Chain

Measuring the carbon footprint of your supply chain is an important first step in reducing your emissions and complying with forthcoming regulations
A carbon footprint is "the total set of GHG (greenhouse gas) emissions caused directly and indirectly by an individual, organization, event or product" (UK Carbon Trust 2008).
Measuring your carbon footprint is an essential step in preparing for US Cap and Trade regulations
The American Clean Energy and Security Act of 2009 established a variant of a cap-and-trade plan. This will likely be passed into legislation in 2010.
– Of note, the "Cash for Clunkers" program was an amendment under this Act
Large emitters of GHGs will be directly influenced by a mandatory cap through requirements to reduce emission, buy carbon offsetting credits
Small emitters will be influenced by the cap indirectly through increases in energy costs
Emissions trading markets do exist in the USA but it is currently voluntary
The more efficient supply chain will be at a advantage once this legislation passes

The process for measuring your carbon footprint in its current state
Calculating Your Carbon Footprint
MappingMapping Segmentation Segmentation Articulation Articulation Calculation CalculationSteps
Activity Details
Objectives
- Map all of the products, processes, transportation and processing associated with your business.
- Mapping ensures that all basic process, products and product flows are captured correctly. This is the highest level activity in the carbon footprinting process
- Separate all processes and flows into three categories: Upstream – products you receive as raw material, Entity - value and non value added business activities and Downstream – all activities that occur once the product has left the manufacturing phase
- Segmentation further defines the map by drawing lines around what occurs prior to, during and after your business has control of materials and processes
- Articulation is the detailed work all inputs/values for Production and Transportation for each segment of your supply chain.
- Articulation provides the details required to calculate the emissions for the supply chain
- Calculate the emissions for each variable- Calculate to the product or unit level- Example: Transportation of wood used in pallet making that transports your product is 0.18 MT CO2e per ton of wood. The product occupies 0.28% of the pallet.
- Calculation includes calculating the emissions for each step in the supply chain. - The sum of this is the carbon footprint

Case Study # 1: The Carbon Footprint of Fat Tire Amber Ale
Beverage Industry Case Studies
11
Case Study # 1: The Carbon Footprint of Fat Tire Amber Ale The New Belgium Brewing Company (NBB) was concerned with their carbon emissions and
decided that the best place to begin their reduction efforts was to understand their current carbon footprint.
Their goal was to reduce emissions and save money.
They conducted a product level life-cycle assessment which included:
– the production of all raw and manufactured materials,
– conversion of those materials into finished products and co-products,
– processing of waste,
– product packaging,
– storage and transportation during distribution and retail,
– in-use emissions,
– disposal or recycling of the product,
– as well as immediate offset projects and any other innovative solutions.

To begin, NBB segmented the Upstream, Entity and Downstream activities
Packaging and Non-Consumable Materials
– Glass (Production and Transportation)
– Paper (Production and Transportation)
– Cardboard (Production and Transportation)
– Steel (Production and Transportation)
– Wood (Production and Transportation)
– Adhesive (Production and Transportation)
– Plastic (Production and Transportation)
Consumable Materials
– Malt and Barley Agriculture
– Barley Production and Transportation
– Malt Production and Transport
– Hops Agriculture
– Hops (Production and Transportation)
– Water (Production and Transportation)
– Carbon Dioxide (Production and Transportation)

They then Articulate and Calculate carbon dioxide equivalent values for each segment (Upstream, Entity and Downstream)
Example: Transportation of Glass:
– Twelve ounce brown glass bottles are deliver to NBB from Windsor, Colorado, a distance of 16 miles.
– These bottles are shipped by OTR truck.
– Class 8 tractor-trailer with an average fuel efficiency of 6.3 mpg, a max cargo weight of 20,000kg and using standard diesel fuel.
– The 16 mile trip requires 2.54 gallons of diesel fuel.
– The production and transportation of a gallon diesel fuel contributes 11.8 kg of Co2 to the environment (West and Marland, 2002).
– The entire trip then emits 29.96 kg of CO2.
– Allocating this CO2e per 6-pack results in a total mount for the transportation of bottles of 1.8 g of CO2(CO2e Carbon dioxide equivalent. A unit of GHG emissions including non-CO2 gases that have been converted to an equivalent mass of CO2 according to their global warming potentials)

NBB then summed all emissions for the entire supply chain
The boundaries of the carbon footprint analysis encompassed the entire supply chain
– Acquisition and transport of raw materials, brewing operations, business travel, employee commuting, transport and storage during distribution and retail, use and disposal of waste.
This analysis goes beyond the regulatory requirements but positions them well for the future.
The largest line item in the tally of GHG emissions is the electricity used for refrigeration at retail.
The next largest sources are production of glass and malt (including barley).
These three sources account for 68.4% of all emissions embodied in a 6-pack of FT.
The carbon footprint of a 6-pack of Fat Tire® Amber Ale (FT) is 3,188.8 grams of CO2 equivalents (g CO2e).

Fat Tire Conclusions and Next Steps

Supply Chain Element
Result from Carbon Footprint Next Steps
Overall The business of creating any beer is linked inextricably to GHG emissions and many of the emissions are today unavoidable.
Set a goal of reducing emissions by 25% by 2015
Raw material production
Raw material production accounts for only 18.6% of emissions but is an area NBB can control better
Switch to organic barley (or barley fertilized from organic sources)
Work with suppliers to reduce emissions during the production phase
Demand planning and fulfillment
Electricity used for refrigeration at retail is the largest single source of emissions.
NBB has little influence over the design of the refrigerators employed by retail centers but they can reduce the emissions by minimizing stock time at retail or the removal of some portion of product from refrigerated section altogether.

Case Study # 2: The Carbon Footprint of Tropicana Orange Juice
PepsiCo, owners of Tropicana Orange Juice, wanted to answer how much does a glass of their OJ contribute to global warming.
They measured the emissions from such energy-intensive tasks as running a factory and transporting heavy juice cartons.
The largest single source of emissions was simply growing oranges.
Citrus groves use a lot of nitrogen fertilizer, which requires natural gas to make and can turn into a potent greenhouse gas when it is spread on fields
PepsiCo found the equivalent of 3.75 pounds of carbon dioxide are emitted to the atmosphere for each half-gallon carton of orange juice.

The Carbon Footprint of Tropicana Orange Juice
Juice production accounts for 60% of all emissions in Orange Juice production
PepsiCo plans to work with their growers and with researchers to find ways to grow oranges using less carbon
They are planning to publish carbon-footprint numbers for products including Pepsi, Diet Pepsi and Gatorade
Next steps include exploring greener:
– Agricultural practices
– Packaging material, quantity and re-use
– Sourcing locations
– Thermal and electrical efficiencies
– Transportation methods to market

Case Study # 3: The Carbon Footprint of Bottled Water
Published in the February 2009 edition of the peer-reviewed journal Environmental Research Letters, the Pacific Institute conducted analyses of the energy requirements for various stages in bottled water production
– This including the energy to manufacture the plastic bottles, process the water and the bottles, and transport and cool the final product.
This was the first peer-reviewed analysis of its kind.
They also apply these inputs to three site-specific examples of the energy required from production to the point of use:
1. Local bottled water produced and used in Los Angeles
2. Water bottled in the South Pacific and shipped by cargo ship to Los Angeles
3. Water bottled in France and shipped in various ways to Los Angeles

Flow diagram of energy requirements of bottled water supply chain
Figure 1. Flow diagram showing examples of where energy is required during bottled water manufacturing, use, and disposal.
They evaluate the energy required in the first four stages, including transportation (colored orange) between them.
Energy is embodied in PET material itself, and additional energy is required to turn PET into bottles.
– This energy is typically supplied by natural gas and petroleum, along with electricity from the local electricity grid.

Beverage Industry Case Studies
24
The largest contributors to CO2 emissions and energy use in bottled water is the bottle and transportation
Most energy requirements for locally bottled water are found in the bottle
Long-distance transport can lead to energy costs comparable to, or even larger than, the energy to produce the bottle.
Far less energy is needed for processing and treating the water, and cooling bottles for retail sale.
Gleick and Cooley find bottled water is up to 2000 times more energy-intensive than tap water.

Total energy requirements for producing bottled water
Bottled water requiring long-distance transport is far more energy-intensive than bottled water produced and distributed locally.

Definition of Terms
Carbon Footprint The carbon footprint, or embodied carbon, of a product or service is the total amount of GHGs emitted across the life cycle of a product. Though there are non-CO2 GHGs that are included in the carbon footprint, the term arises from the most significant GHG: CO2 (carbon dioxide).
CO2e Carbon dioxide equivalent. A unit of GHG emissions including non-CO2 gases that have been converted to an equivalent mass of CO2 according to their global warming potentials
GHGs Greenhouse Gases. TCC’s assessment tracks the six “Kyoto” gases regarded as most significant in terms of their climate impact: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6).
LCA Life Cycle Assessment. An academic field concerned with the accounting of material and energy flows involved in the life cycle of a product or service, and the assessment of associated environmental impacts. TCC’s Climate Conscious Assessment is an LCA of GHGs.
Offsets GHGs removed from the atmosphere (e.g. by growing trees) or prevented from escaping to the atmosphere (e.g. by capturing exhaust from power plants or gases released from landfills) have been commoditized by companies and organizations which market them as a means of “offsetting” comparable masses of greenhouse gases emitted elsewhere. Purchasers of offsets often seek to obtain amounts sufficient to compensate for all their direct emissions, thus making their product/service/activity “carbon neutral.” TCC’s assessment does not consider offsets, since we are seeking to quantify the GHGs emissions immediately related to the production system.
