ABSTRACT
ONE OF THE MORE RECENT AND COMMONLY USED SUSTAINABILITY METRICS is called eco-efficiency. Developed in 1992 by the World Business Council on Sustainable Development (WBCSD) (2005a and 2005b, www.wbcsd.ch), it brings together the essential ingredients necessary for increased economic prosperity— more efficient use of resources and lower emissions. This framework can be used by any business to measure progress toward economic and environmental sus tainability.
