Informed by the above efforts, eco-efficiency metrics were further refined for application at the operational level through the sustainability metrics work of the American Institute of Chemical Engineers (AIChE, www.aiche.org/cwrt/...

Economic and panel approaches are arguably the most common methodologies in aggregating metrics. In the economic approach, metrics are weighted in terms of their associated monetary costs and benefits, both internal and external to the company. AIChE s Total Cost Assessment methodology (TCA, see Section 6.2) and the Environmental Priority Strategy in product development (EPS) (Steen, 1999) are tools that may be used to assess environmental and sustainability costs and benefits.
