The study documented energy use and carbon dioxide emissions generated through the complete cycle of buying a product using Buy.com's distribution and delivery channel as well as through traditional retail store operations. In fact, the study showed that 65 percent of total carbon dioxide emissions generated by shopping at retail outlets related to consumers driving to and from the stores.
Results showed that, on average, Buy.com's model fared better in reducing carbon dioxide emissions and energy consumption with fewer steps in getting products from manufacturers' warehouses to consumers' homes.
