Total Cost Assessment

Apart from the actual purchase cost a business pays a supplier for a chemical, there are costs that are usually not considered. Happily there has been considerable development of approaches to Total Cost Assessments or environmental accounting, and the reader is strongly encouraged to seek out more information about how this is done. Application of Total Cost Assessment will provide a strategic view of trends that can directly affect the long-term viability of a process and is well worth the effort.

Total cost assessment (TCA) provides a comparison of costs of sustainability, and by consequence, a consistent evaluation of alternative processes. 

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. 

Section 6.2.3 is called Total Cost Assessment Looking at All the Costs Involved with a Decision. Traditional decision-making typically focuses on direct and indirect costs that appear on the balance sheet. The TCA model defines three additional cost types, contingent liabilities and internal and external intangibles. A methodology for developing total costs related to environmental impacts is discussed.
