There is no one definition of 'sustainability'.
It can be an idea, a property of living systems, a manufacturing method or a way of life. There may be as many definitions of sustainability as there are people trying to define it.
Most definitions include the notions of:
- living within the limits of what the environment can provide
- understanding the many interconnections between economy, society and the environment
- the equal distribution of resources and opportunities
Sustainable development aims to meet human needs in the present while preserving the environment so that these needs can also be met in the indefinite future.
Environmental sustainability programs include resource efficiency actions to:
- reduce the use of physical resources including water and energy
- encourage recycling
- increase the use of renewable resources
- encourage redesign of production processes and products to eliminate the production of toxic materials
- protect and restore natural habitats and environments valued for their biodiversity or beauty
Environmental sustainability programs aim to strike the balance between benefits for the environment/society and economic costs – helping society to move towards a more sustainable future.
