The definition of sustainability is often described as vague or complicated, this is caused by greenwashing and politricks. Here are 5 definitions and their context to make clear what sustainability is. Also a definition of UN sustainability is added.

Sustainability is:

1 the ability to exist constantly

2 the ability to be maintained at a certain rate or level. “the sustainability of economic growth”

3 avoidance of the depletion of natural resources in order to maintain an ecological balance. “the pursuit of global environmental sustainability”

4 the quality of being able to continue over a period of time: “the long-term sustainability of the community”

5 environment : the quality of causing little or no damage to the environment and therefore able to continue for a long time: “the company’s commitment to environmental sustainability”

UN: “meeting the needs of the present without compromising the ability of future generations to meet their own needs.” As we know this has not been a success since 1987 so I call this UN sustainability; “needs of the present”, “compromising” and “their own needs” leave to much room for wrong interpretations.
