Case Studies in the Environment (2019) 3 (1): 1–14.
Published: 31 December 2019
Abstract
To improve and to protect brand reputation, corporate sustainability officers must assist with decisions about how to manage supply chains to avoid deleterious impacts from consumer products, such as food or clothing. This case study shows how one method typically used to identify problematic materials and sources in a supply chain, life cycle assessment, can be made spatially explicit for water footprints. Water must be understood spatially because the use of the same amount of water in an arid place creates more ecological damage than the use of water in places with ample water resources. This case reports on the development of a spatially explicit water footprint for Guess?, Inc., a global apparel company to highlight “hot spots” of negative impacts on water resources. Freshwater resources consumed throughout the life cycle for a pair of blue jeans were assessed, including the growth of cotton, production of the fabric and other materials, industrial laundering, and washing by the consumer. The locations of these steps were then mapped with a geographic information system to generate spatially explicit water impact estimates. Engaging with this case, students will learn about key methodological choices and limitations in such projects, think about how to advise the company on steps to be taken in its water management action plan, and reflect on the implications for sustainable corporate management of consumer products.
