Studio Working Group Due Diligence and Supply Chain Analysis
Business Challenge:
As part of the Walmart sustainability initiative and packaging scorecard, the Studio Working Group (SWG) was formed by three major studios. These studios worked collaboratively to identify sustainability wins including decreasing the carbon footprint from DVDs and Blu-rays. The first goal was to determine the emissions contributed from each step of the product supply chain for DVD production. The initial study revealed that packaging makes up about 30% of the footprint, a significant part of the product supply chain emissions, and therefore the SWG enlisted ClearCarbon to further investigate the carbon contribution of nine different DVD packaging options.

Our Approach:
- The boundaries of the packaging analysis encompassed raw material extraction through disposal of the product in a landfill.
- ClearCarbon solicited supplier data from over 25 domestic and international facilities.
- To allow flexibility in the analysis, ClearCarbon calculated emissions factors for each packaging material based on weight and surface area for each packaging component.
- The final results of this analysis are detailed GHG emissions values for each major phase (e.g., extraction, manufacturing) and component (e.g., case, tray) of the nine DVD and BD package options based on 2007 data.
Value Created:
ClearCarbon created a complete database of contributing supplier and manufacturing facility data. Using this database, ClearCarbon is able to estimate emissions for various package types based on materials used, size, and weight of each packaging option. This database allows the studios flexibility in testing additional packaging variations made from several previously specified materials, including paperboard, polypropylene, and steel. Results from this analysis have been used to inform the studios and Walmart on the relative carbon “friendliness” of each package variation. The SWG is also conducting consumer preference studies to compliment the findings of the carbon packaging analysis to help aid in determining which package types will be phased in or out of production moving forward.
