CTSA - Chapter 3 - Developing a CTSA

Cleaner Technologies Substitutes Assessment
The aim of a CTSA is to develop as complete and systematic a picture as possible of the trade-offs among risk, competitiveness (i.e., performance, cost, etc.), and conservation associated with the substitutes in a use cluster. To accomplish this, a CTSA employs a modular approach to data collection and analysis utilizing "information modules." An information module is a standard analysis or set of data designed to build on or feed into other information modules to form an overall assessment of the substitutes. A CTSA records and presents facts collected in the information modules, but does not make value judgements or advocate particular choices.

This chapter summarizes the information module approach, describes the flow of information between modules, and provides an overview of the information modules currently in the CTSA methodology
