  Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI): User's Guide and System Documentation (79 pp, 1.21 MB) (EPA/600/R-02/052) June 2003

TRACI allows the examination of the potential impacts associated with the raw material usage and chemical releases resulting from the processes involved in production. With TRACI, the user can examine the potential impacts for a single life cycle stage or the whole life cycle and compare the results between products or processes.

The purpose of TRACI is to determine priorities or conduct a preliminary comparison of two or more options on the basis of the following environmental impact categories: ozone depletion, global warming, acidification, eutrophication, photochemical smog, human health cancer and noncancer, human health criteria, ecotoxicity, fossil fuel use, land use, and water use.

TRACI is an impact-assessment tool that will support consistency in environmental decision making. It is recognized that additional tools may be useful to assess, prioritize, and reduce potential environmental impacts. This user's guide presents information to assist in the use of, limitations and uncertainties associated with, and information concerning the methodologies within TRACI.
