What does Sustainability Mean?
1987 United Nations Brundland Commission: "Sustainable
development is development that meets the needs of the
present without compromising the ability of future generations
to meet their own needs".
From the 2007 West Linn Sustainability Strategic Plan:
Sustainability means using, developing and protecting resources
at a rate and in a manner that enables people to meet their
current needs and also ensures that future generation can meet
their own needs. A sustainable community of West Linn will
balance the needs of individuals and organizations with the
resources and benefits of the natural and economic
environments to create a livable community for future
generations.
