ECO2 Calculator

A program to determine the private CO2 emmission and energy consumption

What does the ECO2 Calculator do?

Based on the individual life-style of the user, the model calculates his or her personal CO2 and energy balance. The necessary data are inquired in four different questionnaires covering the areas nutrition, living, mobility and consumption. Each input results immediately in a modification of the displayed values, so that the user can identify the effects of the individual aspects of his or her life-style easily.

The model has been written particularly for laymen who are interested in the consequences of climate change but who do not necessarily have any scientific foreknowledge. The questionnaires are formulated to be generally intelligable; the graphic output of the results is intuitively understandable. Beyond that the user can compare his or her personal balance with the average per capita consumption in other world regions.
