A New York Times article (March 2, 2011) describes an effort to catalog the environmental impact of every step in the global supply chain of apparel, from cotton growth, to fabric, to dyes, textile manufacturing, packaging, shipping, retail through to the consumer. The factors considered include water, land, waste, chemicals, greenhouse gases impact and labor practices.  The goal is to roll all of these measures across the supply chain into one score. Should supply chains focus on providing one score that summarizes these impacts or should there be a performance score across separate categories like the nutrition list for cereal ? How will such metrics impact retail competitiveness of the supply chain used for production ? Should consumer recycling of the used product, or the frequency of washes and type of detergent used, be included in this overall supply chains score ?
