Abstract
The EFQM Business Excellence Model is used by many larger European Corporates to measure and manage their quality development processes. One target (or results) dimension in that model deals with society results. The perhaps most important quality aspect within that dimension concerns environmental issues. In the present paper a Society Result Environmental Index is introduced. Its main purpose is to provide support for cost efficiently managing investments for environmental improvement to secure better financial results. The measurement procedure that is suggested provides information about the market perception of the environmental status and, even more important, it gives information about how to prioritize profitable environmental improvement. The methodology suggested meets the highest statistical requirements for 'best practice' measurement.
