In order to build this framework for sustainability, society must adopt the four system conditions in order to be ecologically sustainable. TNS summarizes the Four System Conditions in the following text: In order for a society to be sustainable, nature's functions and diversity are not systematically:

1 Subject to increasing concentrations of substances extracted from the earth's crust.

2 Subject to increasing concentrations of substances produced by society.

3 Impoverished by overharvesting or other forms of ecosystem manipulation.

4 Resources are used fairly and efficiently in order to meet basic human needs worldwide.
