Understanding our Environmental Risk Indexes. Toxic Environmental Risks Analytical Intelligence

Abstract

The data at TERAIN are divided into scores and indexes based on PRTR data that has been enhanced through the design of proprietary analytical methodology. This has resulted in the presentation of this data in a more sophisticated form that allows to conduct more complex and elaborated studies. TERAIN’s scores a total of 9 indicators (EPIs) that aim to capture the real environmental impact at the facility, company, and region levels. In addition, TERAIN uses these nine EPIs to generate up to seven comparative Environmental Risk Indexes (ERIs) that situate the scores of every search item in their corresponding percentile. These ERIs rank every facility, company, and region according to the result of their yearly scores, based on cluster analysis methods.
