What is Sustainability?
Sustainability can be defined simply as meeting contemporary needs without compromising the ability of future stakeholders to satisfy their needs. Sustainability attends to three interdependent areas of concern: environmental preservation, economic viability, and social justice.A sustainable practice works to preserve rather than destroy its ecological base, ensure rather than undermine long-term economic benefits, and advance rather than retard matters of fairness, equity and diversity.

Is Sustainability the Same Thing as "Green"?
Green practices generally address the environment. While sustainability also addresses environmental issues such as conservation and stewardship, it looks at the bigger picture to consider issues of social equity and economic prosperity.
