is measured the quotient from the economic value of a product and the effects exercised by the manufacture procedure on the environment, in a suitable unit.

The term was introduced 1991 by the commercial advice for lasting development (Business Council for Sustainable development) into the economic world. The motivation for it was that negative ecological effects and the resources intensity are to be reduced over the entire life cycle (the product) to a level, which is compatible with the ultimate bearing capacity of the earth.

reached, if goods and services are concerning the price competitive, human needs to satisfy and quality of life bring.

The commercial advice for lasting development defines over the formula:

= (economic value of a product)/(influence and/or effects on the environment)

This concept demands the maximization of the value (utility) per unit "environmental impact ". Both the production process and the use/use and the later disposal (with products) into the balance are included ("from the cradle to the Bahre"). The reduction of the material and energy intensity of products and the reduction of the pollutant output are together with the increase of the recycling ability of materials reused by products as well as the maximum employment as small an environmental impact as possible to cause.

is a characteristic number, more economical with which production processes are to be arranged and products. The increase of the environmental compatibility is thereby a positive side effect.

The reduction of the various environmental impact on scalar divisor requires the summary of different factors as for example carbon dioxide output and heavy metal missions, which must be made necessarily as arbitrary selected computing procedures.

The characteristic number does not meet a statement about the fundamental lastingness (load-carrying capacity of the ecological system).
