The 6 Sustainability principles

Conservation of biodiversity and ecological integrity

Maintenance of the abundance of different species living within a particular region, the genetic diversity in a population and the ability of an ecosystem to maintain its biotic and abiotic organisation and function in the face of changing environmental conditions, including a capacity for self-renewal.

Efficiency of resource use

Use of smaller amounts of physical resources to produce the same product or service while minimising environmental impact.

Intergenerational equity

Preserving natural resources and the environment for the benefit of future generations.

Intragenerational equity

Preserving natural resources and the environment for the benefit of the current generation.

Precautionary principle

A guideline that is triggered when the risk of harm to the environment due to a proposed action is high but the scientific evidence is uncertain, requiring that measures be taken to prevent environmental damage and that the proof of no, or minimal, harm be provided by the proposer.

User pays principle

Calls upon the user of a service or resource to pay directly for the amount they use, rather than the cost being shared by all the users or a community equally.
