      In addition you can se the resulting Impact Growth Factor as a function of assumed improvements in Resource Productivity, where Impact is understood as the impact on the environment resulting from consumption.
      To see how sensitive the result is to parameter selection go to the
Supplementary Calculator
      In this calculation present world population is assumed to be 6 billions, with 1.2 billions in the industrialised countries and 4.8 in the developing countries. For details on the calculation goto : Explanation
      Values shown when loading the calculator are default values. You can try the calculator first using these values. Then choose your own values by typing or using the up and down buttons.

Population Growth over the next 50 years in percent

Developing countries :            PG-D    
Industrialised countries :        PG-I      
  

The present I/D consumption factor.

This factor is :
the consumption per capita and per year in the industrialised countries
divided by
the consumption per capita and per year in the developing countries.

Present I/D consumption factor :      I/D      
   

Per capita Consumption Growth in percent p.a.

Developing countries :          CG-D      
Industrialised countries :       CG-I
