Supply Chain as a Complex System: Environmental Impact Evaluation and Perception

Abstract

Customers are aware of the complexity of supply chains and link this to a high environmental burden. However, if not coupled with quantitative results, this may be overestimated. The present paper proposes a general method used in the specific case of deep environmental evaluation of a swimming goggles distribution. The results are compared to the consumers’ perceptions, collected and analyzed from questionnaires, and the remaining product lifecycle stages, assessed through the life cycle assessment (LCA). The design and prototyping phases take place in Italy, the goods are manufactured in Asia, and further commercialized worldwide. The environmental analysis enabled the identification of the most impacting lifecycle phases. Results highlight that for small products, with a simple use phase like the goggles, the distribution phase retains a small percentage of the overall environmental impact; thus, it is reasonable to simplify the modeling of the supply chain by selecting a limited number of significant scenarios. This work proves how important is to quantify and rationalize the environmental impacts of a complex system. The end of life and transport phases are perceived as high impacting, but the life cycle assessment analysis reveals that the materials and manufacturing phases retain the highest impacts and are the first that should be improved. Consequently, proper dissemination, cooperation, and communication strategies should be carried out by the goggles brand toward suppliers and stakeholders; the company is now studying how to replace virgin materials with recycled content to lower the environmental impact without hampering the product’s performance.
