INVESTMENT CLASSES

Investors need a clear, simple way to consider the environmental attractiveness of a prospective investment, as well as to understand how "clean" a portfolio of investments is. ECG developed a unique set of CLEAN™ Investment Classes to categorize technologies according to the relative environmental benefits. This classification is based on a quantitative and qualitative analysis using our CLEAN™ Framework and other information. We use this metric to classify the realized and potential environmental impact of each portfolio company in the PCG CalPERS Clean Energy and Technology Program. By looking at the distribution of portfolio companies across the five CLEAN™ Investment Classes, an investor is able to understand at a high level how clean the portfolio is.



ECG used this framework in the pioneering CalPERS AIM Clean Energy & Technology Program 2008 Environmental Measurement Results Report. Download the Report in Adobe PDF format.
