In a dictionary Sustainability is usually defined as the ability to maintain itself avoiding depletion.
This also gives itself to a Framework at its simplest defined as:
Outcome with interdependent Dimensions and Goals
It is working within this Framework that transforms an Activity or Organisation into a Sustainable one as it directs effort towards common Outcomes.
The United Nations
The Outcome is “Sustainable Development is development that meets the needs of the present generation without compromising the ability of future generation to meet their own needs”
There are 3 Dimensions: Social, Economic and Environment containing 17 international Goals (Sustainable Development Goals or SDG’s).
These 3 Dimensions can be further encompassed within a Worldview/Cultural Dimension in which they belong for example: Forest, Marine, Desert, Urban, Muslim, Christian, Secular, Democratic, Autocratic etc.
