摘要

为了提高和保护品牌声誉,企业可持续发展官员必须协助决策如何管理供应链,以避免来自消费品(如食品或服装)的有害影响。本案例研究展示了一种通常用于识别供应链中有问题的材料和来源的方法,即生命周期评估,如何在空间上明确地显示水足迹。必须从空间上理解水,因为在干旱地区使用同样数量的水比在水资源充足的地方使用水会造成更大的生态破坏。这个案例报告了一个空间明确的水足迹的发展。, Inc.,一家全球服装公司,强调对水资源的负面影响的“热点”。对一条蓝色牛仔裤在整个生命周期中消耗的淡水资源进行了评估,包括棉花的生长、织物和其他材料的生产、工业洗涤和消费者的洗涤。然后用地理信息系统绘制这些步骤的位置,以产生空间上明确的水影响估计。通过这个案例,学生们将了解这些项目的关键方法选择和局限性,思考如何建议公司在水管理行动计划中采取的步骤,并反思对消费品可持续企业管理的影响。

The Spatially Explicit Water Footprint of Blue Jeans: Spatial Methods in Action for Sustainable Consumer Products and Corporate Management of Water
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.
