Hello Leah,

Sustainability is a complex concept and I don't think there is any 
"standard" definition.  If memory serves, the one you suggest is similar 
to the Brundlant definition.  Recently I found a useful compilation of 
definitions:

http://sustainabilityed.org/what/education_for_sustainability/what_is_sustainability.html

I like this one:

"Sustainability is a dynamic condition which requires a basic 
understanding of the interconnections and interdependency among 
ecological, economic and social systems. Sustainability means providing 
a rich quality of life for all, and accomplishing this within the means 
of nature."  Jaimie P. Cloud, Cloud Institute, www.cloudinstitute.org

I would switch the order of the two sentences, but the first sentence 
makes it clear that policy design for sustainability always requires 
inter-disciplinaryr analysis.
