Could anybody explain, in simple terms, what is behind an Environmental Performance Indicator (EPI), or where can I find some information (not too much details) about this topic?

Thanks,

MrStout
 
From a book by Mary Ann Curran Environmental Life-Cycle Assessment, McGraw-Hill 1996:

EPI is a scalar quantity where the total effect of the environmental impacts (by emissions or consumptions per unit of product) is calculated from a weighted average of the impacts. It is based on 13 impact categories, within three main groups:

- Resource depletion parameters-resource effy., 4 parameters
- Health impact parameters-health quality, 2 parameters
- Ecological parameters-ecological quality, 7 parameters
